These 274 lots are part of a large proposed development on a 500.5- acre parcel called Neighborhood One . It is expected to ultimately contain some 1680 lots and associated dwelling units . This Environmental Impact Statement ( EIS ) covers the entire proposed development of Neighborhood One and thus is expected to fulfill the environmental requirements for the remaining applications submitted to HUD during its development. This presumes that the remainder of Neighborhood One will be developed as articulated in the Environmental Impact Report for Neighborhood One , January 1975 and other documents and data supplied by the developer and City of Hercules . Should any substantial changes be proposed by Centex Homes of California , Inc. during the remaining phases of the development of Neighborhood One , a supplement to this EIS with the attendant circulation times for review may be necessary . ���AN SOLNAP NAP A NAPA A NOTLA MAN PARPIELD N RI MA NAPA SOLCANO NOVATO OENICIA 101 SAN RAFA CONCORO • TOWN OF GROW RICONO WALNUT CREEK ART CO CH AN WN PR MODA A SONTARMECDOASTA AL OVALIN YAN R BA HAWWARO PACCA MATEO PREMONT ADA CLARA REDWOOO CITY 101 PALO ALTO SAN JOSE RA CLATA SAN MA SAN SAN FRANCISCO BAY AREA �PROJECT DESCRIPTION The project covered by this Environmental Impact Statement involves 500.5 acres of undeveloped land in the City of Hercules , western Contra Costa County , California . One . " It is the area designated as " Neighborhood The City The city is located in the western portion of Contra Costa County , one of the nine counties comprising the San Francisco Bay region . In the ten years between 1960 and 1970 , the population of the Bay region increased by 27.2 percent compared to 36.5 percent for Contra Costa County and 18.5 percent in West Contra Costa County . The City is in a major path of growth in the Bay region -- accessible by freeway to employment areas in West Contra Costa County , Northern Alameda County and the Benicia area . There is a Bay Area Rapid Transit station in Richmond , nine miles south of Hercules , which provides West Contra Costa County with mass transit service to destinations along the industrial corridor between the cities of Richmond and Fremont , and San Francisco . The City of Hercules is a planned community which is an extension of an urbanizing area already served by major transportation and utility systems. The plan incorporates open space and conservation areas and provides for improved environmental design . The City has the governmental framework to provide its future citizens with needed urban services . HISTORICAL SKETCH The City was incorporated as the Town of Hercules in 1900 and is a general law City of the State of California . members elected at large . It is governed by a council of five The " Hercules Site " of the California Powder Works was established in 1879 . Originally occupying a site in what is now Golden Gate Park , San Francisco , the company decided to find another location and selected a tract of land in San Pablo Bay which was a part of the former Spanish land grant called Rancho El Pinole . In about 1903 , the DuPont Company acquired the California Powder Works and thereafter the plant comprised part of the E. I.

In 1912 , the Hercules Powder Company was incorporated (now known as Hercules Incorporated ) and purchased the Hercules , California plant from the DuPont Company together with other explosive plants operated by the DuPont Company in other States . The Hercules , California plant was the largest producer of TNT in World War I , supplying explosives to Great Britain , France and Russia before the United States entered the war . A few of the houses of the present village were built in 1900 and 1906 , with the majority erected during World War I. In 1902 , the Hercules Water Company was formed which supplied water to the area between San Pablo and Rodeo . This company operated until 1953 when it became a part of East Bay Municipal Utility District . The major landowners of Hercules today are Hercules Incor porated , Sequoia Refining Company and Signal Oil and Gas Company . Today , the City has a population of about two hundred fifty . NEIGHBORHOOD ONE This large tract of land - virtually undeveloped - lies easterly of Franklin Canyon Road and northerly of the ridges above Refugio Creek . Composed of gentle to steep grass - covered hills with trees clustered in the water courses and a few scattered on some of the hillsides , the higher elevations provide occasional panoramic views of San Pablo Bay . At the present time, two subdivisions are under construction : Tract 4745 - La Cresta containing 113 lots and Tract 4746 - Las Laderas containing 161 lots . These subdivision have received HUD approval through its regular subdivision application processing procedures . HUD anticipates receiving applications for approval of each subdivision through the remaining phases of the development of Neighborhood One . Upon the approval of each subdivision , HUD will be able to offer mortgage insurance to all qualified homebuyers within the approved subdivisions. II -2 ��OLS STANDARD G.

E CONCORD ��PART PROBABLE ENVIRONMENTAL III IMPACTS OF THE PROPOSED ACTION ��LAND USE The Centex land holdings in Hercules involve 500.5 acres , all located within Study Area One as illustrated in the City's general plan . This acreage is in the northeast part of town and forms Neighborhood One . It is bordered on the north and east by the City limit lines beyond which are unincorporated areas of Contra Costa County . (Highway 4 ) . The westerly side is Franklin Canyon Road On the southerly side is a strip of land zoned R - 2 within which is Refugio Creek , a natural wooded channel which drains most of Hercules from east to west . Near the easterly end of the site , this creek is the neighbor hood's actual border . The site is characterized by a topography which varies from nearly flat to slopes over 30 % , and reaching nearly 500 feet in elevation . It is virtually all grazing land , with only an occasional tree or small tree grouping , except along the easterly end of Refugio Creek where various trees and shrubs are found . The east branch of Refugio Creek drains the northern part of the site , 1 / and it is proposed to culvert this creek , as discussed under the drainage section of this report . Easements for pipe and gas lines cross these subdivisions. These constitute a use of land which can sometimes be a source of potential danger when they contain petroleum or gas lines that do not meet certain minimum standards. HUD has therefore established such standards and they have been complied with here ( see letters of certification from Standard Oil of California and from Standard Pacific Line Inc. , dated September 19 , 1975 , and September 17 , 1975 , respectively ) . The prevailing winds are from west to east . Proposed Use : The Hercules general plan shows this neighborhood to be developed as low density residential and open space , and to be served by a neighborhood park and an elementary school . Low density is defined as 4.5 dwelling units per acre on the average , with a range varying from three to six dwelling units / acre . " These areas will contain single family detached and attached housing in a residential setting interspersed with open green areas . " 1 Toups Corp., A Plan for Neighborhood One, undated , p.5 . 2/ City of Hercules General Plan , p . 56 III-1 2/ �- �A small area at the southeast corner of this neighborhood is designated as medium - low density ( average 10 dwelling units per acre , with range of six to 14 dwelling units / acre ) . 3/ The predominant housing type will be townhouses , quadruplexes and similar attached dwellings. The general plan indicates a system of collector streets in this neighborhoood , which all end at Sycamore Street, now under construction (see section on Traffic / Circulation ) . Two 60 kv lines traverse Neighborhood One , and have been relocated with in a planned open area in this neighborhood . Two subdivisions are currently under construction . La Cresta and Las Laderas . These are named Together they will provide 274 homes , or approximately 16% of the planned number of dwelling units in the neighborhood . Discussion of Environmental Impacts : The County General Plan for this area dates to 1963. The land around this part of Hercules is under County jurisdiction , zoned Agricultural and Industrial, and is shown on the General Plan as Extensive Agricul tural . The Fernandez Ranch , which immediately abuts Neighborhood One , is used for grazing land under the Williamson Act which insures its remaining open for a minimum of 10 years . Beyond this ranch are vast areas belonging to East Bay Municipal Utility District. for recreational purposes . Some of these lands are made available The County's recreational element shows a proposed system of trails ( riding , bicycles and hiking ) . to form a complete network . The City's plan proposes to tie into these Residential development will therefore accelerate implementation of these trail systems within the City , and will likely cause pressures upon the County to develop them in County areas where they do not now exist , to form a continuous , and hence more usable , network . This would of course be a favorable impact since these trails will be ( eventu ally ) connected with vast watershed lands and major parks which , though not actually adjacent, are very close by . It is also anticipated that development of Neighborhood One will have a favorable impact upon the Fernandez property in that it will enhance its long range desirability for future residential use . If that should occur , annexation to Hercules for sewers would likely be necessary . 31 Ibid , p . 57 III- 2 ��North of this area is Franklin Canyon Road (Highway 4 ) , and between it and the Santa Fe Railroad is industrially zoned land extending east to the golf course . This industrial land is used by the Union Collier Carbon Co. which has been there many years . More recent occupants are the Soprest Co., the Asbury Graphite Co., and currently under construc tion , the John Burton Machine Co. This land is eminently suited to its use because of the availability of the rail facilities . There is considerable hilly terrain between these industrial lands and the developable portion of Neighborhood One . Thus its impact is expected to be minimal. Highway 4 is the only street access and is barely able to adequately carry all the traffic along its portion not yet improved to freeway standards . West of this industrial area is a recently constructed residential development by Singer Co. , which was the subject of a County General Plan amendment approximately three years ago to change the planned use from industrial to residential . This development now contains approximately 250 homes and is growing . It is evident that this entire region is undergoing important changes , each one of which is having impacts which influence further development. The most important of these changes are : 1. Possible residential development of Pinole Ridge , involving some 500 acres between the Hercules City limits and the City of Pinole . 2. Possible redevelopment project in Pinole at southeasterly corner of 1-80 and Appian Way to " Auto Row " type development, and 3. Current construction of Regional Shopping Center at Hilltop Road , west of 1-80 , to include major shops such as Capwell , Penneys , Macy , as well as 150 other lesser stores . The 500.5 acres of this neighborhood are to be developed with some 1,683 residential units and approximately 5,300 people to the area . Detailed development plans for Neighborhood One beyond the first two subdivisions are not available . Conceptual grading plans indicate that vertical separation is to be provided between the development of medium low and medium density areas , and adjoining low density areas which will favorably help to preserve the integrity of the several types of residential development. Near the easterly end of the neighborhood where Refugio Creek borders it , some grading will take place . III-3 ��Subdivision activity will involve certain short term adverse impacts during the construction stages . These include dust , noise , material storage and vibration from equipment operation , all of which may be mitigated by the use of water trucks to control dust , observance of good work practices , specific hours of operation , safety measures , erection of temporary barriers around material and equipment storage, and controlled traffic near and within the project area . All these are to be observed in this development. III - 4 ��EDUCATION The City of Hercules lies within the boundary of the Richmond Unified School District. As the city develops and begins to grow - in terms of population and school- age children - there are three alternative school system organizations open to Hercules . These alternatives are briefly discussed here - not because a decision needs to be made prior to the completion of Neighborhood One , but rather because any decisions made now vis - a - vis bussing , use of portables at a site , etc. could greatly affect the ease with which a future choice of an alternative school system might be made . Alternative A Hercules remains in the Richmond Unified School District . No legal changes necessary Alternative B Hercules transfer from the Richmond Unified School District to the John Swett Unified School District . Since both districts are unified , such a transfer may be legally made . In order to do so , a petition to transfer must be approved by the governing boards of both school districts , by the County Committee on School District Organization , by the County Board of Super visors , and possibly by the State Board of Education . If deemed necessary by the Supervisors or State Board , the petition must be submitted to all the voters of the Richmond Unified School District . School officials have stated that while the process of transferring school districts is difficult , it might have at least a 50-50 chance of success . An argument favoring the transfer might be that with the City of Hercules in the Swett district, it would have a better chance of passing a school construction bond election than would the Richmond School District if Hercules remained there . Without school construction , the Hercules children would be housed in portables or perhaps bussed into Pinole or perhaps further south toward the end of the Richmond District - a considerable distance . III- 5 ��Alternative C Hercules forms a localized district , either by itself or including either or all of the following: Pinole , El Sobrante , or the Singer Development. Since the developing Singer complex at Viewpointe is presently in the John Swett District, a petition to transfer would have to be initiated as discussed in Alternative B. There is a requirement that the assessed valuation per pupil may not vary more than 10 % from the assessed valuation per pupil in all of the territory of which the new district is to be comprised ( i.e. , Richmond and perhaps Swett if the Singer Development of Viewpointe is included ) , except if the assessed valuation per pupil is greater than the State average , it cannot vary more than 15 percent. Therefore , for all practical purposes , this option is most difficult . Even as the Hercules population grows and actual need develops for school buildings , the overall probability of a district -wide approval at a two - thirds level seems remote . A foreseeable condition which might increase chances of its passage would be a change in the state Constitution reducing the percentage of " yes " votes required to pass a school bond election . While there has been pressure for such a change in recent years , it would require passage both by the state legislature and by the voters of the state - a set of favorable circumstances which seems remote under present political and economic conditions . On the other hand , can the John Swett District pass a bond election ? This district has had no need for a bond election for many years and its student enrollment had been decreasing for a number of years prior to the opening of the Singer Development at Viewpointe. Space in its schools is not filled to capacity and the first impact of any increase in enrollment will be absorbed in existing classrooms . Yet , this space is limited and as the Rodeo area continues to grow , the district will be faced with a classroom shortage problem . As this need becomes apparent and if it is augmented by other developments in the area with a resulting in -migration of parents with children in sufficient numbers to overcome local voter opposition , then it is possible that a district -wide school bond election could be successful . Generally speaking , both districts have a good education reputation . graduates who go on to college do well , overall . have gained national scholastic awards . Their Many Richmond students Both school districts have a continu ation school program which has decreased their respective dropout rates . III - 6 ��The Richmond Unified School District has two major racial groups white and black . This year blacks comprise slightly over 33 percent of the total students ; orientals 3.8 % , Spanish speaking 6.7 % , and other non - whites account for 1.3 % . The schools in the Pinole and El Sobrante areas have few black students , whereas the schools in the southern and central portions of the district have a high percentage of black enrollment . The racial composition of the John Swett Unified School District has been about the same since the Rodeo Elementary school District was unified with Swett. This unification introduced a black student population of about five percent into the district for the first time. Swett has always had somewhere near fifteen percent Spanish - surname student population concentrated for the most part in the Crockett and Port Costa areas . The ethnic composition of this district can be described as remaining fairly constant at about five percent black , fifteen percent Spanish - surname, and the remainder white plus a scattering of " other " races . Construction has now started in the first two subdivisions of Neighbor hood One in Hercules and families are expected to occupy their homes around the first of the year in early 1976. The first school age children will attend schools in the adjoining Pinole area of the Richmond Unified School District . The district has anticipated these students both in terms of school planning and personnel, and their planning figures indicate that the district's regular school enrollment will probably drop as fast' or faster than the growth of new students generated by the development of Neighborhood One . A list of those schools most likely to house these early students from Hercules is contained in Appendix A. Officials of the Richmond District indicate that when the number of elementary -age children generated by the Hercules development reaches 150 , the school district will look toward placing portables at the designated school site until such time as they decide to construct a permanent school. financed by a bond issue , have to vote on it . If it is to be residents of the entire Richmond District will Meanwhile , bussing arrangements will have to be set up between the City of The City Manager of Hercules and the Richmond Unified School District . Hercules notes that the Richmond Unified School District has agreed to provide bus service for the children of elementary school age . No transportation will be provided for children attending junior and senior high schools - they must arrange for their own transportation . Appendix B shows the attendance pattern presently experienced in the Richmond Unified School System . This same progression will apply to students from Hercules who attend any of these schools . III - 7 ��Comparison of Tax Rates Richmond and John Swett Unified School Districts 1975/1976 Tax Per $ 100 of Assessed Valuation General Purpose Education Richmond John Swett $ 5.204 $ 2.4931 Community Services .10 Meals for the Needy .05 Repayment of State School Loan .073 $ 5.427 10 $ 2.5931 Interest and principal on bonds issued prior to unification (Paid by Pinole /Hercules .119 property owners only ) $ 5.546 $ 2.5931 The total assessed valuation of the City of Hercules for the 1975/1976 fiscal year is $ 15,308,798 . The general tax rate levied by the City of Hercules is $1.00 / $ 100 of assessed valuation . The current levy for the Richmond Unified School District will raise some $ 849,026 from the City of Hercules . The 1990 General Plan for the City of Hercules provide for five elementary schools at 10 acres / school and a junior -high school site of 45 acres . Neighborhood One has allocated five acres for an elementary school site located next to a park site of some 6.5 acres . It has been indicated in conversations between the developer and the City of Hercules that this school site will be dedicated to the Richmond Unified School District in an improved condition (graded ) . The park will be reserved for school use during school hours through a joint powers agreement yet to be expected between the school district and the City of Hercules . Expected Impacts It is estimated that the full development of Neighborhood One could gener ate opproximately 800 K- 6 students , 230 intermediate students and 240 high school students . At the present time, around two hundred of the elementary students and over one hundred of the intermediate students III - 8 ��could be housed in existing facilities of the Richmond School District without causing a crowded condition . However , these students will be generated on an incremental basis over a five - plus year period as various stages of the development of Neighborhood One are completed so that the impact in any one year will not be major . By the time the development of Neighborhood One has generated some 300 K- 6 students , portable units already owned by the district can be moved onto the school site provided by the developer . In this manner the potential adverse impaction of the school buses will be avoided . This facility will be expanded as the student population grows . Additional sites shown on the Hercules General Plan (i.e. , Refugio Canyon ) will be developed or transportation to nearby schools provided as the size of the school age population dictates . The Richmond School District is presently experiencing high enrollments at the junior high and high school levels . However , as these peaks pass in the next two to three years , attendance area boundaries may be adjusted to accommodate the Hercules students in available facil ities . (See Appendix B , page III - 10 ) . The financial impacts on the Richmond School District are expected to be similar to those normally experienced with the completion of any residential development. The provision of the improved school sites at no cost to the District will mitigate this impact to a significant extent. The Hercules area of the District has historically generated substantially greater revenues than expenditures for educational services due to the high proportion of industrial property as compared with the number of students . It is antici pated that there will continue to be a somewhat higher ratio of assessed value per student for the Hercules area than for other areas in the school district .

Elevation varies from sea level to slightly over six hundred feet on the south -west boundary of the city . Numerous canyons and gullies transect the dominantly grassy sloped foothill areas , and have created microhabitat areas characterized by chaparral and oak woodland . Cattle and sheep grazing has been exten sive in recent years and has resulted in the maintenance of an open grass land and closely cropped chaparral habitats . A considerable amount of the townsite lying northward between Interstate Highway 80 and the bay is occupied by the Hercules Chemical Plant and numerous oil tanks constructed for the Sequoia Oil Corporation and recently sold to the UCO Oil Company of Whittier , California . In addition , a small residential area originally built by Hercules , Inc. for its employees lies adjacent to the present chemical facilities . Nearly 55 % of the lands the city lie southeast of Highway 80 and are virtually undeveloped . of This area is primarily open , heavily grazed grasslands, intersperced with areas of chaparral, eucalyptus , and oak woodland . Man's influence in this area has been limited to the construction of a few miles of road and railroad track , an electrical power transmission line and stock fencing . A. PRESENT ENVIRONMENT The area comprising Neighborhood One has rolling hills with both gentle and steep slopes forming ridges and valleys along and east- west alignment. The entire area slopes downward to the west . Vegetation The predominant ground cover and habitat type for Neighborhood One is grasslands with a few willow trees scattered along the natural drainage clefts . Approximately twenty small to medium sized native oak and bay trees along with native shrubs such as poison oak lie in one of the canyon areas . The major native tree communities of the City of Hercules are not located within the boundary of Neighborhood One . The grasslands dominate the area on the drier westerly and southerly facing slopes , and for the most part , occur as the dominant habitat type as a result of heavy sheep and cattle grazing . In fact , the riparian vege tation has been greatly affected by grazing activity . Many of the plant species characteristically found along watercourses have been closely cropped , resulting in only limited areas of willow and some valley oak III - 12 ��remaining . This habitat type is limited to Refugio Creek along the southern boundary of Neighborhood One . Wildlife The wide expanses of grasslands periodically broken up by shrubs and trees provide excellent habitat for such species as hawks , eagles , vultures , robins , meadowlarks and flickers . During a field survey by Jones and Stokes Associates , Inc. on January 19 , 1973 , red - tailed hawks ( Buteo Jamaicensis ) and sparrow hawks (Falco Sparverius ) were the most common raptors observed . These birds cruise over wide areas of grassland search ing for pocket gophers ( Thomomys bottae ) , harvest mice ( Reithrodontomys Megolotis ) and miscellaneous small birds and reptiles which inhabit the area . Along the streamsides and in the eucalyptus groves , warblers , juricos , thrushes , and chestnut- backed chickadees were observed . For the most part , eucalyptus is of little wildlife value ; however , the groves do provide cover and roosting for several species of perching birds . These riparian areas are important to many species of amphibians and reptiles and several carnivores such as the long tail weasel (Mustela Frenata ) and spotted skunk (Spilogale Putorius ) . The oak woodland habitat type provides food and cover for black - tailed deer , gray squirrels and other rodents , California valley quail , and ous other avian species. numer Although oaks provide little wildlife cover per se , their value is highest when combined with other habitats and vegatative forms such as coyote bush , California laurel and other species . Some of the oak woodland is also associated with a source of water , and this provides all the major components for optimium wildlife habitat - food , cover and water . Most wildlife species found in the chaparral habitat type frequent other habi tats throughout the area , as the presence of just one vegatative form such as coyote brush is of little value to wildlife . Where the chaparral was inter spersed with oak woodland , grassland and other habitats , wildlife such as black - tailed deer (Odocoileus Hemionus Columbianus ) and California quail ( Lophortyx Califomicus ) are abundant . According to the California Department of Fish and Game California Fish and Wildlife Plan , black - tailed deer densities range from 10 to 30 per square mile in tats . Contra Costa County woodland - grass and chaparral types of habi Deer densities in the Hercules area are within this range , as 15 were observed during field studies by Jones and Stokes Associates , Inc. Esti mates for California quail in Contra Costa County range from 10 to 50 birds III - 13 ��per 100 acres . Other population estimates for game species found in the Hercules area include mourning doves ( Zenaidura mocroura ) 10 to 100 per 100 acres in woodland - grass habitats and band - tailed pigeons (Columba fasciata ) (winter migrants ) occurring in densities from 10 to 100 per 100 acres . Since there is little suitable upland habitat, mammals and reptiles are limited . No known rare or endangered species of plant life , mammals , reptiles or amphibians are believed to occur in the Hercules area . B. ANTICIPATED IMPACTS Impacts upon the existing wildlife species of both flora and fauna will occur as a result of construction activities and the development of Neighborhood One . The extent of the development of the project will of course , determine the degree to which the existing wildlife will be impacted . The majority of the impacts caused by construction and development are considered to be direct , since habitat loss as well as decreases in both wild life population and existing species of plant materials will result from exten sive physical modifications of the existing environment . On the other hand , changes in air quality , noise and other more subtle factors will affect all species of wildlife indirectly . These impacts may be of short or long term duration , depending on the magnitude of the impact on the environment and whether or not mitigation measures are enacted . It is anticipated that impacts on the wildlife of Neighborhood One and sur rounding area will occur in two different phases of the project - during construction and after development. Construction - related impacts are us ually considered to be of a short term nature , while those related to the end result are long term . Short Term Impacts ( 1) Construction activities will disturb existing vegetation and related wildlife species . The initial impact will be encountered during the construction phase with the resulting disturbance of the vegetation cover indirectly affecting the wildlife utilizing that vegetation . Grading , filling and related activities will result in the disruption of established patterns of birds , mammals , and reptiles utilizing the surface environment. Those adaptable species capable of coping with the changes may return to the area after construction activities have ceased . III - 14 ��( 2) An increase in erosion and turbidity will occur in water courses throughout the area as a result of the construction efforts . Any construc tion activities will result in changes in the quality of water flow through out the area of Neighborhood One and the surrounding areas . Refugio Creek and other intermittent streams drain all the upper slopes sur rounding them . Grading , filling and related activities will disrupt the existing soil mantle which will tend to create erosion problems and the subsequent situation of streams , no matter how intermittent they may be . This environmental change will indirectly affect wildlife by interrupting the feeding patterns of amphibians , mammals and birds depending upon the lower forms of vertebrate and invertebrate life in the streams . Long Term Impacts ( 1 ) The development of Neighborhood One will result in the direct alteration and / or loss of existing natural wildlife habitats , leading in turn to a change in the size and distribution of wildlife population . All of the habitat types , riparian , chaparral and grasslands - found in the lands of Neighborhood One , will be affected to some degree by the projected development. (a ) Riparian - Changes will occur along sections of Refugio Creek and many seasonal streams joining it from the foothills to the east. Road alignments plus the filling and grading activities will eliminate existing habitats in some areas . will cause permanent loss of that habitat . These fill areas ( b ) Chaparral - Many " pockets " of chaparral habitat will be eliminated primarily by the filling of parallel valleys which occur on the east - facing slopes on the western side of the hills . Many of these canyons have a conglomerate of vegatative forms which provide excellent habitat for deer , quail , numerous song birds and small mammals as well as some reptiles and amphibians . These filled areas will eliminate all future use by wildlife particularly where roadways and houses will be constructed . ( c ) Grasslands - This habitat will probably receive the greatest impact as a result of development. Many acres of existing grass lands in Neibhborhood One will be altered or eliminated by housing , roadways and schools . Among the wildlife species to be affected by the loss of grasslands will be red - tailed hawks , sparrow hawks , mourning doves , turkey vultures , band - tailed pigeons , rough - legged hawks , California quail, meadow larks , valley pocket gophers , California ground squirrels , pacific gopher snake, and numerous III - 15 ��other species of birds , amphibians and reptiles . Development will cause displacement of a majority of these species although small populations will probably be maintained in many of the grassland areas remaining as open space . ( 2 ) The development of Neighborhood One will result in changes in the "carrying capacity " ( the maximum density at which a wildlife species can be maintained in a habitat ) of the area . Since development will cause an alteration in wildlife populations , this will be a direct impact . Due to the decrease in available habitat as a result of development, the numbers of many wildlife species will be decreased . Those species relying on grasslands or which require large areas of diverse habitat will be affected the most . Since there will be less land avail able for food and cover , the individual mammals , birds or reptiles now inhabiting areas to be developed will be forced into habitat already supporting wildlife or into marginal areas that may be unsuit able . The end result will be either ( a ) a lowering in the population size or , ( b ) an over utilization of the remaining resources , i.e. , greater overbrowsing by deer resulting in environmental degradation and ultimate loss of animals . ( 3) Development will directly disrupt established life patterns among some wildlife species , i.e. , roads and housing may sever travel ways used by deer . Other wildlife have developed patterns of movement according to their needs . Quail , for example , may now move from one brushy canyon across an open patch of grassland to another canyon to feed or drink . Although their movements are far more limited than larger animals such as deer , they are still dependent on travelling to that patch of food or spring . Construction of roads , homes and other develop ment will disrupt these established patterns , particularly where plans are for areas of open space to become " islands " among the homes and roads . The results may be a high incidence of road kills and the likeli hood of problems with wildlife " invading " the residential areas and causing depredation ( eating ornamental shrubs , etc. ) . ( 4) The development and resultant loss of habitat will result in changes in the species or composition of wildlife . With the advent of housing , roads and other development, many of the wildlife species inhabiting the area now will be greatly reduced in numbers or possibly eradicated . Because wildlife populations are affected , this impact is considered direct. Ani mals commonly occurring such as sparrow hawks , red - tailea hawks , mourning doves , black - tailed deer and others will be replaced by species III-16 ��more tolerant of development and less dependent on open land . These species will include juncos , warblers , sparrows and other songbirds . The diversity of the species will be dependent on the degree of habitat manipulation .

All waste materials are in either Groups 1 , 2 , or 3 in this system , and each group has its own particular storage , handling , collection , and disposal requirements . A summary of the groups is presented in Appendix I. In general, however , toxic and hazardous wastes are in Group 1 ; Group 3 wastes are inert solids , such as construc tion and demolition wastes ; and all other wastes , including most residen tial and commercial refuse , are in Group 2 . This assessment deals primarily with Group 2 materials which will be gener ated by the future residents of Neighborhood One . The collection of Group 3 wastes - generated usually by a demolition or construction contractor is principally accomplished by two methods : either the contractor hauls his own wastes or he contracts with the franchised waste hauler to deliver and pick up debris boxes . Collection points and volumes are on an ad hoc basis according to the location of the activity , and agreements are negotiated between the generator and the hauler . It should be noted that regulations governing the storage and collection of Group 3 wastes are at a minimum due to the inert nature of the wastes . Although no Group 1 hazardous material is anticipated as a result of the development of this project, the collection and disposal of these materials is briefly covered in the section on liquid waste . Current Collection At the present time the City of Hercules has a refuse collection contract with the Richmond Sanitary Service ( formerly known as Pinole Garbage Service ) . This contract was executed in August of 1967 and runs for fifteen years with an option to renew for an additional ten years . This contract gives the Richmond Sanitary Service the exclusive right and privilege to collect and dispose of all garbage , rubbish and swill in the City of Hercules and to retain all salvage therefrom and to make and retain certain charges for the use of the garbage disposal premises owned by the company . Although the contract reserves the right of the City of Hercules to charge the company ( at a rate similar to that paid to neighboring cities and public agencies ) a fee for the right and privilege to collect and dispose of all garbage and rubbish , in actual practice the city currently pays $ 285 monthly to the company for this service . This fee covers twice per week collection at sixty collection points primarily in the residential village of the city . At the present time, this fee is slated to rise to $ 297 monthly in 1966 for the same sixty collection points . III - 20 ��The two industrial concerns , Hercules , Inc. and Sequoia Refinery ( now Gulf ) each dispose of their various waste accumulations under separate contracts apart from that executed by the City of Hercules . Included in the contract with the City is a guarantee by the Richmond Sanitary Service that they will comply not only with such ordinances as the City of Hercules currently has in force or will be passed in the future relating to the collection and disposal of garbage refuse and swill , but also the sanitary laws of the State of California . In addition , they agree to maintain at their own cost and expense a sanitary collection service and disposal system in compliance with applicable ordinances of the City of Hercules and the regulations of the Regional Air Pollution Control Board . Current Disposal All solid waste materials collected in the City of Hercules under the existing contract is disposed of or dumped in the West Contra Costa County Dump . This sanitary land fill is located at the end of Garden Tract Road in North Richmond and is owned and operated by the same Richmond Sanitary Service which holds the contract for collection and disposal with the City of Hercules . It currently serves as a landfill disposal for West Contra Costa County from the border with Alameda County north to the area of Rodeo . It also receives an estimated fifteen percent of Marin County wastes plus commercial / industrial wastes from the City of Berkeley . It is licensed to receive hazardous (Group 1 ) liquids in bulk or barrels and both Group 2 and Group 3 waste materials . In May 1960 , the Contra Costa County Board of Supervisors passed a county - wide solid waste ordinance to regulate collection practices and institute rat control. The following month regulation of disposal sites was added . With the advent of these regulations and the restrictions on burning , many of the then existing " dump " were closed . Prior to that time, hog feeding and open burning were regular practices . According to the County Health Department, such facilities were maintained , among other places , near the cities of Pinole / Hercules , Crockett and Martinez . An event that had a major impact on disposal site operation in western Contra Costa County was the classification of sites by the Water Resources Control Board on March 2 , 1972. These are shown in Appendix II . The previously discussed waste class groupings were established at the same time. The regional water quality control boards were instructed to determine the potential threat posed by each disposal site to the state's waters . Then , discharge specifications were issued to each site and the site operator was required to file for a discharge permit. III - 21 In so doing , he was required to ��indicate how site modifications and methods of operation could meet the specifications before a permit was issued . Periodic inspections are made by the regional board staff to note compliance or lack of same with the permit. In extreme cases , the regional boards can issue cease - and - desist orders or revoke permits . In essence , the categorization of a site into either Class I , Class II , or Class III reflects the degree of probability that the wastes in the site may come in contact with water and / or pollutants could be conveyed from the site boundaries to state waters . For example , a Class I site has an extremely low probability ; a Class III designation implies certainty of contact and / or conveyance . Class I sites may accept Group 1 , 2 or 3 wastes ; Class II sites may accept Groups 2 and 3 wastes ; and Class III sites may accept only Group 3 wastes . In practice , with a few minor exceptions , Group 1 wastes are deposited in Class I sites , Group 2 in Class II , and Group 3 in Class III sites . The West County Dump is classified as a Class II site as well as a Class I I site . Thus , it is able to receive hazardous (Group I ) liquids in bulk or barrels and all Group 2 or Group 3 wastes . It should be noted that there are no specifically designated Class III sites in Contra Costa County and thus Group 3 wastes are accepted at all Class II sites for use either as cover or fill material . The West Contra Costa County Dump , opened in 1952 , receives approximately 480 tons per day of wastes in the 175 acres open for current operations . The entire area available for disposal operations is estimated to be around 350 acres . However , if some levees have to be removed due to a U. S. Army Corps of Engineers initiated law suit , approximately 61 acres would have to be removed from this use . If the entire 350- acre site can be filled to plus forty feet elevation above mean lower low water , nearly 14 million cubic yards of volume would be available for refuse disposal . The site operator /owner has filed a closure plan with the City of Richmond that shows the conversion of the site to a recreational area after filling is completed . An analysis which takes into account the anticipated population increases in the various areas of Western Contra Costa County and Marin County which now contribute to the dump estimates its closure between 2010 and 2015 . Future Collection and Disposal Discussions are currently underway between the City of Hercules and the Richmond Sanitary Service Company to provide for the collection and disposal of all garbage refuse and swill which will be generated by the future residents of Neighborhood One. One possibility is an extension of the present contract to include the additional collection points or residences in the project. III - 22 ��Another approach being examined by both parties would involve the sale of specially - treated 32 - gallon paper bags by the company to the residents of the area . These bags would then be placed on the curb for pick - up by the company on designated days with no other charge to the householder than the cost of the bags. These bags would , of course , meet or exceed all county standards for storage of refuse and vector control. In either case , the collection and disposal of all garbage , refuse and swill will be accomplished in accordance with the provisions of Title 5 , Section 5-2.09 of the Hercules Municipal Code and any future ordinances which may be enacted . Future Disposal and Landfill In like manner , the contractor , Richmond Sanitary Service , will continue to dispose the collected solid wastes in its facility - the West Contra Costa County Dump in accordance with all current and future operations governing such facilities . A major study of the entire solid waste problem as mandated by State law ( Senate Bills ) is currently nearing completion . Entitled Contra Costa County Solid Waste Management Plan , it offers a number of alternatives for future solid waste collection and disposal including the financial and admin istrative requirements of each . Although the alternatives differ in details , they all proceed from a closure of the West Contra Costa County Dump in Richmond sometime between 2010 and 2015. New facilities include a series of transfer stations which will take much of the collected and segregated waste to energy - recovery facilities , the first of which may be constructed as early as 1978. By 2010 a countywide landfill would open to dispose of the solid wastes for all of Contra Costa , and transfer stations would facilitate hauling from outgoing areas . Other alternatives include additional energy and resource recover / facilities within the County and / or the export of excess waste to energy and resource recovery facilities outside Contra Costa County . Whatever alternative is adopted , it is clear that the collection and disposal of all anticipated solid waste generated by the present and future resident including Neighborhood One in Hercules - will of Contra Costa County Thus it would appear that the solid waste generated by the development of Neighborhood One will not create an adverse environmental impact , but rather its collection and disposal is being prepared be adequately provided for . for in a proper manner .

III - 26 ��CIRCULATION / TRANSPORTATION Highway 4 (Franklin Canyon Road ) is presently the only road serving Neighborhood One. It is a two - lane highway connecting 1-80 with Martinez and beyond. The Santa Fe Railroad generally follows a paralleling align ment with Highway 4 , and the two cross each other via a grade separating structure . This structure is very close to the entrance to Neighborhod One , and because of its configuration , results in a dangerous access point. Development of Neighborhood One , or any portion of it , will result in a dangerous adverse impact upon this access point. The circulation element of the Hercules General Plan provides a solution , full implementation of which will completely mitigate the problem . This solution will extend Willow Street through an interchange of Highway 4 via Sycamore Street to San Pablo Avenue going under 1-80 . The shorter term solution involves continuing Sycamore Street from Neighborhood One to San Pablo Avenue - this has recently been completed . Sycamore Street is a four - lane divided road with a peak hour traffic capacity of over 2000 vehicles per hour , and therefore more than adequate to serve all Neighborhood One with enough capacity for other planned develop ments within the City of Hercules . The neighborhood will have internal circulation via two collector streets (Lupine and Redwood ) off Sycamore , forming a modified loop through the area . These two streets are to have 40 ' curb to curb pavements in 56 ' right- of -way , which will result in two 12 ' lanes (wider and divided at intersection with Sycamore to increase the intersection capacity ) plus two parking lanes , which will adequately serve the completed neighborhood . The City's General Plan recommends the eventual development of Highway 4 to a six - lane freeway and an interchange with Willow and Sycamore Streets , as well as additional ramps off 1-80 at Willow and Highway 4. Once con structed , these will all contribute to better circulation in the entire area , but until then they will have no direct impact on Neighborhood One . The development of Neighborhood One may result in pressures upon the City and the State by the new residents for quick improvement of Highway 4 to freeway status all the way from 1-80 to Martinez . III - 27 ��The City's General Plan makes provisions for Highway 4 , from I - 80 east ward , to be a scenic route . Approximately one mile of this highway is within the Hercules City limits . Since this is a major entrance to the City , every effort will be made to assure its attractive development, particu larly in terms of landscaping . This responsibility will be primarily with the State and with the developers of the restricted industrial districts which border it within the City limits . Right-of-way for the development of Highway 4 to freeway status has been acquired within the City limits , but its design and interchange with 1-80 are not completed. It is currently in a state of limbo due to the lack of funds. Consequently there is no possible way at this time to know what the final design will be nor when it might be constructed - some estimates range as high as ten years . One particular issue concerns the current Highway 4 and its crossing with Santa Fe Railroad near the entrance to the subdivision . The dangerous aspects of this interchange have already been mentioned . It will affect and be affected by the development of Neighborhood One in an adverse manner which will worsen as a result of the added traffic . The Sycamore Street extension to San Pablo Avenue will partially alleviate this by taking traffic destined southbound on I - 80 . But traffic destined northbound on I - 80 must continue to use Highway 4. For this traffic , two problems will be intensified . One is the Highway's underpass with Santa Fe RR . This condition will be -worsened with the added traffic and an increase in accidents may be expected . Mitigating actions could include warning signs or flashing caution lights . The other problem spot concerns access from Neighborhood One to Highway 4 . Currently no left turns are allowed , and people wishing to turn left must first turn right to go some distance where unobstructed views of the road permit making a U - turn . When Highway 4 is relocated in its new right- of- way , existing Highway 4 can be redesigned as an offset intersection with Sycamore as shown on the City's General Plan . Transit: BART's nearest station is some nine miles south in Richmond . A connecting bus service (by AC on contract with BART ) is provided to Pinole Valley Road . That is not far enough to serve this neighborhood . Moreover this bus service only operates during morning and evening commute hours . The 1680 homes to be developed in this neighborhood will result in an immediate demand for extended bus service . This could be provided by extending the route along San Pablo Road and Sycamore Street to the development. Not providing this service will result in the increased use of the automobile with accompanying air pollution as well as gasoline consumption . III- 28 ��Another transit service is provided by Greyhound Bus Lines on San Pablo Avenue , about a mile west of this development. There are no scheduled stops in Hercules . As development increases in this city , public demand for a stop may result in having it , but it may be about a mile or more away from Neighborhood One . Thus the immediate problem of reducing automobile use will not be greatly alleviated by Greyhound . Expected Impacts The configuration of the crossover of the railroad and Highway 4 presents a dangerous traffic situation under current conditions . Any increase in traffic as a result of the development of Neighborhood One could aggravate this situation . Furthermore , the lack of left turn lanes at the present access to the two subsivisions is extremely hazardous . Completion of the Sycamore Street four lane element to San Pablo Avenue has mitigated the situation to some extent and will increasingly do so in the future . Over 90 % of the traffic generated by Neighborhood One is expected to use 1-80 and over half of this will be south bound and thus will use Sycamore Street. Negotiations are currently underway between the City of Hercules and the developer to close the current access to Neighborhood One from Highway 4 until the eventual realignment and upgrading of this route as indicated in the Hercules General Plan . The City of Hercules is currently seeking funds to enable it to either obtain and operate or contract for the operation of a jitney or small bus . This would provide a temporary transit connection to the AC Transit bus service at Pinole Valley Road until such time as increased patronage would encourage AC Transit or other public transit service to the City of Hercules . III - 29 ��PUBLIC SERVICES AND MUNICIPAL CAPACITY Fire Protection In the early 1950's the Board of Supervisors of Contra Costa County decided that almost all of the County should be in some public fire protection jurisdiction in order that all property in the County should pay its share of the fire fighting function . At the present time , the City of Hercules does not have its own organized fire department. Instead , the City is located within the jurisdiction of two fire protec tion districts , each of which cover approximately half of the corporate limits of the City as well as areas outside the City . The Rodeo Fire Protection District covers the northern half of the corporate city limits of Hercules , the unincorporated community of Rodeo and surrounds both the Union 76 Refinery to the north and the PG & E Generating Plant to the east . Service is rendered from the Rodeo Fire Ştation and the present fire insurance rating is 9 * for the undeveloped areas of Neighborhood One . It is anticipated that the developed area of Neighborhood One with its improved access , water hydrants , residences built in compliance with municipal codes , protection rating of 4 * . etc. , will receive a fire The Pinole Fire Protection District covers the southern portion of the City of Hercules including Neighborhood One , older " village " residential area and the county area lying outside the coporate limits of the cities The City of Pinole formally contracts with and of Hercules and Pinole . renders fire protection services to the Pinole Fire Protection District and to the City of Hercules excluding that area protected by the Rodeo The present fire insurance rating for the older Village Fire District . and for the other areas in the City which have fire hydrants is 4. All other undeveloped areas lying within the Pinole Fire Protection District are rated 9 . The current contract between the City of Hercules and the City of Pinole for fire protection services was executed on August 18 , 1975 and while it is to be effective through June 30 , 1976 , it shall be deemed to have been renewed from year to year thereafter unless either party gives written notice to the other party of its election to terminate such written notice to be provided at least 360 days before the date of expiration or the expiration of any period of renewal . *Fire insurance ratings - national standards based on level of fire pro tection available . One is best to 9 which represents virtually no pro tection . III - 30 ��Consideration for the fire protection services provided by the City of Pinole is " an annual amount which represents the same percentage of the adopted Pinole fire protection budget costs as the prior year's Assessed Valuation of that portion of Hercules for which fire protection services are provided is of the total prior year's Assessed Valuation of the entire area served directly or under contract by the Pinole Fire Department . " Each year , within 60 days of the adoption of the City of Pinole budget by the Pinole City Council, Pinole shall notify Hercules by letter as to the current year's budget costs and the annual charge for the current fiscal year . It should be noted that under the terms of this contract no specific level or degree of service is expressly or impliedly guaranteed . Rather , Pinole will render that degree or amount of service that is consistent with fire protection service that is ordinarily rendered by a muncipality in Contra Costa County to properties within its boundaries . Furthermore, the City of Hercules agrees , under the terms of the contract to hold the City of Pinole free , clear and harmless from any and all claims arising out of the actions, or failure to act of the City of Pinole and its employees providing these fire protection services . For several years , representatives of the cities of Hercules and Pinole as well as the officers of the several Fire Protection Districts in northwestern Contra Costa County have been searching for a way - through annexation to consolidate the existing fire protection services under a tax rate which would be equitable to all parties concerned while at the same time protecting the employment and retirement benefits of current employees of the several districts . They are working closely by desire and by law - with the Local Agency Formation Commission but so far they have been unsuccessful in finding a solution that will , among other things, result in the entire City of Hercules being covered by a single fire protection agency or district . It is not the intent of the City of Hercules to plan for or develop its own fire protection capacity . Police Protection The City of Hercules does not have an organized police department with nor does it have a security patrol. trained personnel and police equipment In past years , Hercules has contracted with the City of Pinole for police protection services - including security as well as criminal . On October 20 , 1975 , a new agreement was executed between the cities of Hercules and Pinole for police services which is effective through June 30 , 1976 but which shall be deemed to have been renewed from year to year thereafter unless either party gives written notice to the other of its decision to terminate at least 360 days before the date of expiration of any renewal period . III - 31 ��Consideration for these services is based upon actual hourly personnel costs including wages and benefits plus vehicle costs (which is composed of depreciation as well as operation ) . Finally , a 25 % administration and over head amount is added to the summary figure to obtain the annual cost . This annual cost - which is set at $20,515 for the 1975/1976 fiscal year covers the basic services which are described below . Any additional services required in the sole judgment of the Police Chief of Pinole or his designee , as a result of criminal activity occurring in Hercules , shall be authorized by the Police Chief of Pinole . On the other hand , in the event that non - criminal activity occurring in Hercules may require the assignment of additional police personnel and / or the expenditure of funds for non - salary expenses related thereto , such may be authorized jointly by the City Manager of Hercules and the Police Chief of Pinole following agreement between said officials as to the level of additional services to be provided and the cost therefore which shall be paid by Hercules . In both cases , criminal or non - criminal activity , the required or authorized additional charges shall be paid by Hercules within 30 days of the receipt by Hercules of detailed billings which set forth the cost items incurred , the rates therefore and the total amount due . The rates for these additional costs for the fiscal year 1975/76 are a part of the recently executed agreement. The annual contract amount for Basic Services and the applicable rates for additional services shall be amended annually not later than 60 days after the adoption of the City of Pinole budget by the Pinole City Council . The basic police protection services to be provided by the City of Pinole within the corporate boundaries of the City of Hercules are as follows: 1) Enforcement of State statutes and Municipal Ordinances . 2) Three hours of one - man police patrol per day from July 1 , 1975 through January 31 , 1976 , and four hours of one - man police patrol per day from February 1 , 1976 through June 30 , 1976 , plus detective and juvenile officer support as necessary ; not exceeding , however , a required total of such support of 1.2 hours per week from July 1 , 1975 through January 31 , 1976 , and 1.6 hours per week from February 1 , 1976 through June 30 , 1976 . 3) A system of reciprocity shall exist wherein if in the sole judgment of the Police Chief of Pinole or his designee , an emergency should arise in either City which would require temporary diversion of officers and vehicles from the other city , the Police Chief of Pinole or his designee may to order on an emergency basis . III - 32 ��As with the various other city services which the City of Hercules contracts for performance from other agencies or companies, the level or type of service will be increased or added as the population of Neighborhood One increases and the need dictates . The general philosophy of the City of Hercules is to contract for the provision of most general services normally undertaken by a city rather than to develop the costly staff and capital improvements which would otherwise be required . In each contract provi sion is made for future expansion of the level of service or the addition of other types of service as the growth of the City may dictate . Ambulance Service In order to insure adequate private ambulance service throughout the County while at the same time preventing cut- throat competition , the office of the County Administrator has divided the county into zones , each of which is served by one private ambulance service . In each instance , the service is issued a permit to operate , subject to revocation by the county . Each contract which exists between the ambulance service and the county spelling out services , rate , etc. contains a " need and necessity " clause . This clause compels the ambulance company to expand its fleet , personnel and level of service in the future as the " need and necessity " of the population of that zone dictates . Service to the City of Hercules and Neighborhood One is provided by the Cadillac Ambulance Service located at 4601 Nevin Avenue in Richmond , California . Their zone of operation goes north to Crockett , south to Albany and El Cerrito on the Contra Costa County line and east of Highway 4 to Barry Hill . At the present time , they have a fleet of nine fully equipped ambulances and , as noted above , more will be added as need and necessity which includes increased population in the service area - require . Response time from the company's office in Richmond to Hercules and/ or Neighborhood One is nine minutes . Within the next six to nine months , the Company plans to have one ambulance unit stationed in Pinole to more adequately service the Rodeo -Hercules - Pinole area . response time from nine to three minutes . This will cut the The ambulance company services the four area hospitals which have 24 -hour emergency room facilities . These are : 1) Kaiser - Richmond Hospital South 14th and Cutting Boulevard Richmond , California 2) Richmond Hospital 23rd and Garvin Richmond , California III - 33 ��3) Brookside General Hospital San Pablo , California 4) Doctor's Hospital 2151 Appian Way Pinole , California In each instance , Cadillac Ambulance Company maintains two -way commu nication with the hospital's emergency room for continuous medical assist ance enroute to the hospital. At the present time , fifty percent of the ambulance personnel are enrolled in the Emergency Medical Technician , Class I course . the other half will take the course . Upon completion , The company hopes - by the end of the next six to eight months - to have some of its staff begin the EMT Class II course . Upon completion , this would mean that the technician could defibrillate and administer injections , thus upgrading their services even more . At the present time , the fees , which are approved by the County , are : $ 55 base rate for pick - up $ 2 per mile from location of pick - ups to selected hospital $ 10 additional if it is an emergency run ( to cover insurance , etc. ) The company honors Medicare as well as Blue Cross and all other medical plans. Hospital Facilities The Hercules area , including Neighborhood One is primarily serviced by two hospitals insofar as basic and emergency medical care is concerned . These are : 1) Brookside General Hospital San Pablo Avenue and San Pablo Dam Road San Pablo , California 2) Doctor's Hospital 2151 Appian Way Pinole , California III - 34 ��There are two hospitals in Richmond , Kaiser Richmond ( 86- beds ) and Richmond Hospital ( 92 -beds ) which have twenty - four hour emergency care , but because of the distance involved it is not anticipated that they will be primary medical facilities for the Hercules area . Brookside General is licensed for 246 beds and is currently operating at 63-64 % capacity . It has a six - bed burn unit to which referrals are made from all parts of western Contra Costa County . No referrals are made from the eastern part of the county which confirms the primary source of these cases - the industrialized western county area . The entire burn unit is currently being renovated which will better qualify the area to render this specialized type of care . Brookside General began a $ 10,826,000 general construction project in September of this year which involves both expansion and modernization . No new beds will be added ; however , there will be expanded surgical and emergency room facilities as well as enlarged outpatient capacity . Provision of the expanded outpatient facilities is supported , in part , by a one - third HEW grant of some $ 843, 866 , the remainder being provided by the hospital. The hospital plans to expand in the future if and when a demonstrable need should arise . Brookside General is the largest hospital in the area and is a District hospital supported by property taxes . Shortly after the end of World War II , the California State Legislature passed the California Hospital District Law which allows apport of local citizens to form hospital districts for the construction and local hospitals . In 1948 , the West Contra Costa County Hospital District was formed by the residents of several cities and parts of cities including Richmond , San Pablo , Hercules , Pinole , Rodeo , etc. The hospital was built with the assistance of a Hill - Burton Grant of some $ 850,000 . Later an additional grant of around $ 750,000 was obtained to contribute to the addition of a radiation therapy wing , and now a grant of $843,866 in Hill - Burton (HEW ) funds has been received to upgrade the outpatient facilities . The state law which provides for the formation of the hospital district expressly forbids the hospital from accepting indigent patients except for emergency treatment. However , the Hill -Burton Act , which supercedes state law , specifically states that the hospital, as a condition of its receipt and use of these Federal funds , must provide uncompensated services to those unable to pay annually in the amount of 10 % of the total grant amount for a period of 20 years following the receipt of the Hill - Burton Funds . III - 35 The ��original construction grant was over 20- years ago , so it is no longer being used as a basis for calculation ; however , the radiation therapy grant requires the hospital to presently provide $75,000 of uncompensated services annually . This will increase by $84,000 per year when the funding for the current grant is completed . All other indigent patients must be transferred to the County Hospital in Martinez which is supported by the County . Doctor's Hospital is a modest private facility licensed for 137 beds , which currently operates at around 50 % capacity . A new 14- bed specialized wing is currently being completed at a cost of some $ 600,000 . This wing will become the Coronary Intensive Care Unit . Thus , it would appear that the level of health care available to the residents of Hercules and Neighborhood One is adequate for now and for some time to come . Municipal Capacity As noted earlier , the City Manager and City Council have generally upheld the philosophy that wherever possible , City services should be contracted for rather than have the City undertake the financial burden of providing them itself. The latter course would require a substantial capital invest ment in equipment and buildings as well as the considerable expense of staffing. The Police and Fire Services are already obtained by contract with ample provision for expanded services as required in the future . Street sweeping functions in the Village are currently contracted for from a citizen of Hercules . As requirements for this service increase in the future , a contract will be let to a major firm who specializes in this service . These contracts are let on the basis of lowest bid and the procedure is not unusual for smaller California cities . The current property - tax rate levied by the City of Hercules continues in Fiscal year 1975-76 as it has in recent years at $ 1.00 / $ 100 assessed valuation . In November 1974 , the voters of Hercules empowered the City Council to raise this tax rate to a level of $2.00 / $ 100 assessed valuation whenever deemed necessary , but so far this power has not been exercised . The City Council has not as yet determined whether to organize and support a local park and recreation district or to contract for such services . The subject has been under general consideration for some time . The City intends to expand its staff only as the need arises and to enlarge its services only as law and residential demand requires . the financial burden can be kept at a minimum . III - 36 In this manner , ��Expected Impacts No significant negative impacts are anticipated in the area of public services or municipal capacity as a result of the development of Neighborhood One which will not be adequately mitigated . The City of Hercules will probably always be a relatively small suburban community due to its corporate city limits . Thus it has made the choice to provide the expected city and public services through the vehicle of contractural arrangements rather than expend the high capital costs of providing these services with their own staff and equipment . As a result the annual costs to the city are expected to be considerably less than would normally be the case which , in turn , is presumed to result in a lower tax rate . In addition , as additional or expanded services are required due to increased population , there will be the resultant added number of homeowners whose property taxes will add to the total revenue due the city . Finally , it is expected that there will be a somewhat higher ratio of assessed value per homeowner for the Hercules area than for many other cities in western Contra Costa County due to the significant amount of industrial property in the city . III - 37 ��AIR QUALITY In this project , which involves changing undeveloped land into a residential development of some 1700 homes , with an elementary school, the major source of pollutants will be carbon monoxide ( CO ) generated from automobiles . Two roads or highways have been identified as major traffic carriers . These are Highway 1-80 and the Scycamore -Willow Loop . For the purpose of this analysis , we have assumed that: 1. 1-80 will carry by 1985 , 89,000 ADT , and that the Highway 4 interchange with it will not have been constructed . 2. That the Sycamore Street extension will have been connected with Willow Street , but the interchange will not have been constructed with Highway 4. carry 21,000 ADT . This Sycamore- Willow Loop will Since the greatest pollutant from traffic is Carbon Monoxide ( CO ) , this analysis was confined to this pollutant, and found to be as follows: 1-80 Sycamore Street 1 hour emission 21,201 ug / m - sec 6539 ug / m - sec 8 hour emission 5,115 ug / m - sec 2106 ug / m - sec 24 hour emission 2,959 ug / m - sec 1117 ug / m -sec Total daily emission 422,750 g / day 239 , 400 g / day By application of the procedures in computation sheets 3 and 4 , * these figures translate into a regional Carbon Monoxide calculated emission of over 1,810,000 grams per day , or a regional scale concentration for 1 hour averaging time of .76 ug /m3, and 42 ug for an 8- hour concen tration time . At the local level , the standards for Carbon Monoxide , in ug / m3, are 40,000 for 1 hour , and 10,000 for 8 - hour concentrations . It can be seen from the Project Summary Form # 1 ( Appendix A ) , that the calculated air quality impacts for the project are well within the Therefore , the project's impact upon the air quality will be standards . minimal . * From the Guidelines for Air Quality Impact Analysis of Projects , by BAAPCD , June 1, 1975. See Appendix III - 38 A for form worksheets . ��To this conclusion must be added three items which have not been con sidered in the calculations . All of them will undoubtedly contribute to the quality of the air to some degree . Because of their distances from the project , however , their impact will be regional local ) , and therefore virtually insignificant: 1. ( as opposed to The regional shopping center under construction at Hilltop Road will be a major traffic generator , and will contribute to the regional air pollution . 2. There have been rumors of an expansion of the oil refinery located near the bay side of Hercules next to the Hercules , operations, Inc. approximately 2 km west of the subject project. Such an expansion will require a permit subject to approval of both BAAPCB and EPA , to insure that any pollutants would fall within established standards . 3. The third item pertains to the tank farms located North of Hercules and Rodeo , also approximately 2 km away . These facilities do , project. on occasion , However , generate smell which may reach to this because of the wind patterns in the Carquinez Straits area , ** prevalent only the North and Northeast winds which occur primarily during November to March would bring these odors to the project site . During the remainder of the year , winds are primarily from the East and South and would therefore tend to blow any odor away from the development. **BAAPCD , Information Bulletin : San Francisco Bay Area , June original March , A Study of Air Flow Patterns in the 15 , 1970 .

T. & S. F. Railroad , Highway 4 and Sycamore Avenue . Most of the affected areas lie within the two subdivisions now under construction , Tracts 4745 and 4746 . This noise impaction has been analyzed in a report dated July 14 , 1975 , by Buomaccorsi and Associates , Consulting Engineers . The report stipulates that the noise impaction will be small , and will affect 31 lots . Without attenuation measures , the homes on these lots would fall within the " Normally unacceptable " category as defined in HUD Circular 1390.2 regarding Noise Abatement and Control . All the affected lots are located along Sycamore Avenue, 100 ' distant; Franklin Canyon Road , 60 ' distant; and AT & SF rail road , 300 ' to 350 ' distant. In a subsequent letter dated September 17 , 1975 , the Consulting Engineers recommended approval of proposed attenuation means by Centex Corporation . These involve the construction of a 3 ' - 4 " high masonry wall along the property lines for lots 7-10 , and 18 of Tract 4746 , and lots 37-42 and 52-55 of Tract 4745. A 6 ' high masonry wall is proposed along the property line of lots 1-3 , 17-20 , and 36 of Tract 4745. * These walls will reduce the noise level to the " Normally Acceptable " category , and have been made a condition of approval by HUD . Therefore the original adverse impact of noise upon these two subdivisions will have been successfully mitigated with the con struction of these walls . Subsequent subdivisions in Neighborhood One that are affected by noise from these sources will also have to be analyzed by an accoustical consultant for mitigating requirements . An analysis of the proposed development of Neighborhood One together with a review of the anticipated vehicular traffic indicates that the remainder of the interior areas - at full development - will generate a noise level well within the " Normally Acceptable " category . There are no lower level flight patterns nor industrial noise generators in the near vicinity of this residential development. * The number of lots does not correspond with the 31 mentioned earlier because of lotting redesign that took place subsequent to the original report. III -47 ��WATER SUPPLY . Description A. of Water Supply Facilities Estimated Project Water Demand Neighborhood One , upon completion is estimated to have an average daily water demand of 757,000 gallons per day assuming a total of 1683 dwelling units using an average of 450 gallons of water per unit per day . B. Existing Water Facilities Water service to the project will be served by the East Bay Municipal Utility District (EBMUD ) from their Sobrante Filter Plant . The District presently has diversion rights for 325 million gallons per day (mgd ) from the Mokelumne River . Demand on the District is 211 mgd or approximately 65 % of the allocation . Water for the Hercules area is filtered at the Sobrante Plant and pumped through a 42 inch main to the 22 million gallon Maloney Reservoir from which a 48 inch main feeds a 36 inch and a parallel 24 inch main serving the area northerly to Crockett . A 12 inch water main from the parallel 24 and 36 inch mains ( interconnected ) is extended easterly under Interstate 80 Freeway to serve the project. The pressure in this 12 inch main is reported to be adequate to serve properties located up to 200 feet elevation . The Sobrante Filter Plant has a 60 mgd capacity and is presently treating mately 20 mgd . As of 1974 the District was supplying approxi approxi mately 100,000 gallons of water per day to customers in the City of Hercules . 2. Discussion of Future Water Service Facilities A master plan for water service to the project is in the design stages by EBMUD and is expected to be available in March 1976 . III -48 ��A copy of the master plan for water service will be made available to HUD for review to determine adequacy of water service to the project. Preliminary planning reported by EBMUD indicates the first two units of the project development already under construction can be adequately served by connection to the existing 12 inch water main under 1-80 Freeway . Service to future units and especially to properties located above an elevation of 200 feet will require con struction of a pumping plant and ground level water storage tank located on a high ridge in Neighborhood One by the developer . A ground level water storage tank of approximately two million gallons capacity is now being planned for location at an elevation of approximately 500 feet on one of the higher ridges in the north eastern part of the development to serve properties between the Properties much over 200 and 400 foot elevations approximately . units , can be expected 30 to 20 an , estimated elevation the 400 foot to require future construction of another storage tank at an elevation greater than 600 feet and probably off the development since the Detailed ridge contours on the project peak out at less than 500 feet. design plans of these proposed water supply facilities will be avail able from EBMUD when completed in March 1976 . 3. Water Quality to be Supplied the Project Chemical and bacteriological quality of the treated surface water supplied by EBMUD to the project from the Sobrante Filter Plant meets current California State Department of Health and United States Public Health Service Drinking Water Standards . The EBMUD provides water supply under permit from the California State Department of Health who routinely monitors quality of water service . No impact on the quality of the water is anticipated as a result of the addition of pumping stations and reservoirs . 4. Financing of Increased Water Supply Provision of all water facilities such as mains , oversizing , lift stations and reservoirs is done by EBMUD . The financing is done on a 60 / 40 % basis with the developer supplying 60 % of the total cost at the time the subdivision is developed . Then , as the houses are hooked up , the developer receives 100 % pay back of its share of the total costs . This is the standard procedure with all subdivisions located within the EBMUD service area . III - 49 ��LIQUID WASTE 1. ( SEWERS ) Description A. Sewage Collection System The Hercules / Centex Development of Neighborhood One is within the corporate city limits of Hercules . Sewer service is to be furnished the development by City of Hercules . The developer will construct the sewer collection system to the City of Hercules standards and connect into the existing Hercules sewer system at two locations . A 12 inch trunk sewer serving the northern portion of the development increases to 14 inch diameter on the east side of the Interstate 80 and connects to the 18 inch Hercules trunk sewer just west of 1-80 on Willow Avenue . A future 12 inch sanitary sewer is planned to serve the southern part of the development which slopes toward Refugio Creek and will connect into the same 18 inch Hercules trunk sewer extended easterly under I - 80 after reduction in size to 12 inch diameter . considered adequate . B. Sewage Trunk sewer sizes are Treatment Plant Sewage from Hercules is treated at the City of Pinole sewage plant under a joint powers agreement between the two cities . The Pinole plant has a 2 million gallon per day design capacity and presently is loaded to approximately 65 % of its capacity . The 0.7 mgd remaining plant capacity is available to serve proposed development in the two cities reportedly on a first - come basis . The subject project is estimated to generate an average of 531,000 gallons of sewage per day based on capital and 5310 persons from house dwelling units . 100 gallons per day per 1303 single family and 380 town This is 26.5 % of the treatment plant capacity and 75 % of the remaining plant capacity . III - 50 ��2. Discussion A. of Sewage Plant Capacity Present Capacity The 0.7 mgd capacity remaining in the Pinole plant is reported to be available on a first- come, first served basis under the joint- powers agreement between the cities of Pinole and Hercules and could serve up to approximately 2000 more dwelling units to be built in the two cities of which 1683 units are now proposed in the subject project. There may not be capacity in the Pinole plant for both the subject project and the 500 or more units of local urban renewal housing recently approved by the City of Pinole . A more specific reservation agreement between Hercules and Pinole would be required to assure capacity in the Pinole plant for the 1683 units in the subject project . It is now uncertain whether Pinole would permit most of the remaining sewage plant capacity to be used by Hercules . The City Engineer for Hercules indicates that to date the City of Pinole has used approximately one half of the remaining plant capacity . If so , then there is capacity in the Pinole sewage plant for approximately 1000 of the 1683 dwelling units planned in the subject project. Completion of the project would require either construction of additional capacity in the Pinole sewage plant or adoption of the Western Contra Costa County Waste Water Management Program by the Board of Directors of the West County Agency and the six or so cities and sanitary districts involved . B. Plans for Future Expansion of Sewage Plant Expansion The Western Contra Costa County Waste Water Management Plan is scheduled for public hearing in February and voting in March things , 1976 . 1976 It would provide , among other if the recommended alternative is adopted , pumping the sewage from Hercules and Pinole to the San Pablo Sanitary District sewage plant for treatment . Capacity would be designed to pump and treat sewage expected from future development in Pinole and Hercules through the year 1990 including the subject project . III - 51 ��3. Acceptability of Sewage Treatment by Pinole Plant to Regulatory Agencies The Pinole sewage plant was completed in 1973 with effluent discharge to coastline of San Pablo Bay . The discharge require ments were upgraded by the California Regional Water Quality Control Board the same year requiring a 45 to 1 dilution of This could the plant effluent to protect coastal shell fish . be achieved by construction of an outfall line from the plant into deep water in San Pablo Bay estimated to cost in excess Such a project is not in conformance with the of $ 5 million . recently adopted comprehensive Bay Basin Water Quality Plan and would not be eligible for Federal and State financing of 87 % of the costs . Thus the project would require local financing . The WCCWMP recommendation (to pump sewage from Hercules and Pinole to San Pablo sewage plant) would likely be eligible for Federal and State funding and could result in much less cost to residents in Pinole and Hercules than the cost for expansion of the recently completed Pinole plant. The Pinole sewage plant has been in violation of the CWQCB discharge requirements since 1973 but has received yearly waivers pending the outcome and adoption of the WCCWM Program expected to be voted on in March 1976 . 1. Future Alternatives for Sewage Treatment If the Waste Water Management Program is approved , then Pinole and Hercules sewage will probably be permitted to increase to 2 mgd total flow until the new pumping plant is available at which time additional sewage flows from construction planned through 1990 in both cities will be permitted . If the program is not approved , sewage flows will likely continue to be limited into the Pinole plant to 2 mgd by the California Regional Water Quality Control Board until either the Pinole plant is expanded There is concern that Pinole or some other plan is developed . Hercules residents may not be willing to assume more costs for sewage treatment beyond those of the Pinole plant completed in 1973 . III - 52 ��if the WM Program is not approved , the CWQCB may be expected to impose a moratorium on further connections to the Pinole sewage plant until the Pinole plant is expanded and a deep water outfall is provided . Expected Impacts A significant impact on the Pinole sewage plant may result with construction of the project unless there is assurance that Pinole has in fact consented , under the joint - powers agreement between Hercules and Pinole , to the obligation of 0.53 mgd of the 0.7 mgd remaining capacity in the Pinole sewage plant. This in fact leaves only 0.17 mgd available for sewering future planned developments in Pinole . The use of the remaining capacity of the Pinole plant is on a " first- come , first- served " basis . A minor long term impact on future sewage plant capacity will result from construction of the subject project if the alternative recommended in the Wastewater Management Program is approved as now scheduled for adoption vote in March 1976 by the six cities and sanitary districts involved . Approval of the program will obligate property owners in Pinole and Hercules to inance additional costs of sewage treatment beyond the costs of the sewage plant completed in Pinole in 1973. This is mitigated to a considerable extent by the fact that the 1683 additional property owners in Neighborhood One will also share with existing property owners in Hercules and Pinole the inancing of the local share of new sewage plant construction whether under. the Wastewater Management Plan or in improvements to the Pinole sewage plant as required by California Regional Water Quality Control Board . if the Wastewater Management Plan is not adopted an impact on future con struction in the City of Pinole may result from construction of Neighborhood One in that sewage from the total development will take up 26.5 % of the existing capacity and 76 % of the remaining capacity in the Pinole sewage plant. Added pumping costs can be expected for pumping the sewage to be generated by the subject project from Pinole to San Pablo plant if the alternative recommended n the Wastewater Management Program is adopted . This long term impact vould be mitigated by the additional revenues generated from the 1683 property owners in the project. Che installation of a new sewer system to serve this project in land not previously developed removes future options for other land uses in this area vhich might not require a sewer system and could be considered a long term legative impact on the environment. However , these impacts would be onsidered in the EIR which would be required for such a system . Provision of a public sewer system into the area also provides for orderly planned levelopment and adequate sewer service to new property owners as a long erm positive impact. III - 53 ��As noted previously , adoption of the alternative recommended by the Waste water Management Plan will not be up for vote until March 1976. Rejection of this alternative could result in the need for a moratorium on future sewer hookups either in Neighborhood One or in Pinole whenever capacity in the Pinole Plant is reached . Furthermore , continued use of the Pinole Plant could require substantial additional expenditures to bring the current sewage treatment plant into conformance with Regional Water Quality Control Board requirements . In order to provide still another alternative - should the Wastewater Manage ment Plan alternative be rejected - the cities of Hercules and Pinole have entered into preliminary discussions with the San Pablo Sanitary Sewer District looking toward ultimate annexation . Should this occur , the same procedure outlined in the Wastewater Management Plan would be undertaken , i.e. , elimination of the Pinole Treatment Plant and the pumping of Hercules and Pinole effluent to the San Pablo Plant . There is considerable support for this alternative which would provide a large assessed valuation base for financing the necessary improvements . In a gesture of good will and to begin building a reserve for financing the construction whichever alternative is finally enacted , the City of Hercules has increased its sewer connection charges from $250 to $ 500 per dwelling unit . In addition a sewer service charge of $ 67 /year has been levied upon all users of the system to fund the operational maintenance and debt service of the adopted system . III - 54 ��HOUSING The Hercules housing market area includes Richmond , El Sobrante , San Pablo , Pinole , Rodeo , Hercules , Crockett , and Martinez , Vallejo , in Solano County , may also be a factor . In 1975 , the population of Western Contra Costa County was estimated by the County Planning Department at approximately 170,000 or some 29 % of the County's total population of 582,829 for that year . The rate of growth for the entire county has decreased since 1970 to 4.9 % , a significant departure from the 1960-1970 decade when the rate was approximately 15% . The county now contains 15 incorporated cities and , in the 1975 special census , changes since 1970 were as follows : their population POPULATION STATISTICS for INCORPORATED CITIES CONTRA COSTA COUNTY Percentage Jurisdiction Numeric 1970 1975 Antioch 28,060 33 , 215 5,155 +18.4 Brentwood Clayton Concord 2,649 1,385 85,164 3,662 1,790 1,013 405 +38.2 9,509 +11.2 El Cerrito 25 , 190 252 94,673 22,950 2 , 240 131 856 9.1 52.1 4.2 2,196 +13.3 3,091 2,071 +27.3 +15.6 +18.1 Hercules Lafayette Martinez Moraga Pinole Pittsburg Pleasant Hill Richmond San Pablo Walnut Creek Total Incorporated Source : 121 20 , 484 19,628 16,506 11,327 18,702 14,418 13 , 266 20,651 15,337 24,347 24,610 25,398 3,696 788 79,043 21,461 39,844 378,565 70 , 126 8,917 19,392 46,034 409,793 2,069 6,190 31 , 228 Change +29.2 + 3.2 11.3 9.6 +15.5 + 8.3 1970 Federal Census and 1975 Contra Costa County Special Census . III - 55 ��The median personal income for the county increased 37 % since 1969 to $15,026 in 1974. Special census data in April 1975 showed that only 5.3 % of the labor force was unemployed . ABAG projects a high employment picture for the county through the year 2000 . In addition , the Western portion of Contra Costa County is blessed with a marine climate with little fluctuation from the average . Hercules is one of the few still vacant areas that are close - in , being approximately 30 minutes by automobile from downtown San Francisco , 5 minutes from Richmond , and less than 5 minutes from the new Hilltop Shopping Center now nearing completion . PRICE RANGES The median price for a single family detached home in the Bay Area ( 9 Bay Area counties ) today is approximately $ 38,000 . The Centex develop ment in Hercules currently involves 2 subdivisions , one selling at a price range of $ 39 , 450 to $42,950 . It will have 113 houses , of which 73 are now under construction . sell from $45,000 to $57,000 . have been brisk . The other is planned to have 162 homes to Forty homes are under construction . Within the market area , the supply of new housing is limited . Sales It con sists of the Viewpointe Subdivision by Singer Company , less than a mile About 250 homes are there , selling at a competitive price of distant. $ 40.000 to $ 43,000 . Most have been sold , and Singer is currently pre paring to develop the last unit of single family homes . In Richmond , Peterson and Moretti's Hilltop subdivision involves about 200 single family homes ; and in Pinole Valley , has about 74 homes . Leadership Homes ' Summit Development Both of these developments are in the low $50,000 price range . Sales to date at the Centex development fall in two categories: Previous homeowners are buying the more expensive homes , buyers are purchasing the lower prices models . 1) and 2 ) First There appears to be no particular pattern of buyers' origin . They are not necessarily limited to the market area . Some come from as far away as San Jose , Sunnyvale , Sonoma , Napa and Fairfield . Although no special survey has been taken , it is reported that shorter commuting time is an important factor in drawing customers to the development. Required annual income to qualify for purchase of the lower priced homes in this development is in the vicinity of $ 20,000 substantially higher than the 1974 median household income, county wide , of $ 15,026 annually . Monthly income required for a 71 % loan is about $ 1,600 , III - 56 and for a 94 % ��loan , about $ 1,800 . For first time buyers , this usually means that both adults of a family are wage earners . Most of these buyers are under 30 years of age . For those first time buyers originating from within Contra Costa County, these homes do offer an opportunity for upgrading if the down payment requirements can be met . In the more costly homes , this is no longer true because the equity from the previous home allows larger down payments to permit relatively small mortgages and therefore smaller monthly payments . All types of people are purchasing homes in this area . That is to say , there is cross section of white and blue collar workers , as well as government workers . Approximately 80 % are Caucasians , and the remaining 20 % are composed of Spanish surnames , blacks and orientals , and other minorities . It is interesting to note that the 1975 special census indi cates the following racial and ethnic identities for the County : Oriental , 1.8 % ; Black , 6.3 % ; American Indian and other nonwhite minorities , 1.7 % ; Spanish /Mexican , 3.3 % . Based upon the City's policies enunciated in the general plan , its holding capacity is 7690 dwelling units to be achieved by 1990. All these will be new units since Hercules , Inc. has been demolishing existing units in poor condition as they become vacant. It is anticipated that by 1990 , all of the still existing units will have been demolished . not counted in the inventory . They are therefore STATISTICAL INFORMATION : In 1975 there were 65,940 dwelling units ( all types ) in Western Contra Costa County . Three thousand eighty six ( 3,086 ) of these were vacant, of which 1,500 were single family homes . These vacant single family homes represent approximately 2.3 % of the housing stock . The 1975 census also shows that of the 65,940 dwelling units , 62,215 were classed as sound or deteriorating , ( based on the exterior condition of walls and foundation , roof and chimney , windows , doorways , porches and stairs. If there were obvious defects which did not extend over a large area , or if repairs were needed to provide adequate shelter against the weather , the unit was counted as " deteriorating . " At census time, 2,578 dwelling units fell in this category ). Although these deteriorating units do need work , they cannot be considered uninhabitable and are therefore included with the " sound " ones for the purpose of showing that only 5.6 % of the housing stock in Western Contra Costa County is classified as dilapidated , inadequate in original con struction , or under extensive repair . III - 57 ��According to the Contra Costa County Planning Department, the County's housing stock by 1980 is expected to contain approximately 230,000 units , of which 163,200 or 70.8 % will be single family homes . The remainder would be multiple units , the proportion of which has been increasing in this county since 1960 when there was one apartment for each 7.6 dwelling units . By 1970 , the ratio was 1 in 5 , and in 1974 had increased to almost 1 in 4 , when apartments accounted for 24 % of the housing stock . continue . This trend is expected to In order to meet the expected stock of single family homes by 1980 , approximately 12,580 homes would have to be constructed each year . Subject development will produce 1,683 , or 13 % of these homes . It would appear that the development of Neighborhood One will help relieve the tight single - family housing market in this price range . Proof of this demand is confirmed by the brisk sales record at La Cresta and Las Laderas as well as the successful marketing of the nearby competitive Viewpointe Development in Rodeo . III - 58 ��Geology , Seismic , Hydrology , Soils and Flood Drainage Neighborhood One covers approximately 500 acres lying easterly of Franklin Canyon Road and northerly of the ridges above Refugio Creek . The Plan proposes approximately 1750 dwelling units with accompanying community facilities , open space areas and circulation routes . This neighborhood area is bounded on the northwest in part by Franklin Canyon Road and A.T. & S.F. Railroad right of way , and on the south by Refugio Creek . The site could generally be described as the northern half of the eastern end of the City of Hercules . The area can be characterized as having rolling hills with gentle and steep slopes generally forming ridges and valleys along an east -west alignment. The site slopes downward to the west . Elevations range from a maximum of 500 feet above sea level at the exteme northeast corner of the site to a minimum of approximately 40 feet above sea level at the southwest corner of the site . Typical slopes in the area range from a nearly flat condition in the southwest portion of the site to over 30 % in the Central and northeast portion of the property . 1/ Climate data for the site area was obtained from the Oakland weather station which indicated that Berkeley was the nearest monitoring station to the Hercules Area . Average annual rainfall is 22.12 inches per year . Average monthly temperatures vary from a low of 49.8° to a high of 64.40 with a yearly average of 57.1º . Prevailing winds from the site are generally westerly and southwesterly . 2/ GEOLOGY: The geologic investigation of Neighborhood One identifies five soils and rocks types which includes Upper Briones sandstone , Hercules shale , lower Briones sandstones , valley Alluvium and Rodeo shale . These were investigated by direct borings and by seismic surveys . 1.

In each slide area water was encountered at or near the slippage plane lubricating the sliding planes . Beneath all slide areas at relatively shallow depths hard rock was encountered making it possible to correct or control these areas in design phases of development .

Soil creep occurs in areas of expansive soils on slopes ranging from very gentle to steep . The mechanism for soil creep is repetitive shrinking and swelling within the soil mass , with movement downslope accelerated by gravity during the swell function . Much of the area underlain by clay rich shales , such as the Hercules Shale and interbeds of shale within the Upper and Lower Briones Sandstone can produce expansive soils upon weathering , which are subject to soil creep on steeper slopes . Mud flows have originated on the steeper slopes in the Hercules Shale unit due to heavy , protracted rainfall . The head areas of the mud flows have sluffed materials to depths of less than 10 feet, with maximum depths of four to six feet being typical. Ground water has not been identified in any significant quantity in prelimi nary geologic and soils investigation . There is no indication that sufficient ground water of a quality and quantity to constitute a resource is available in Neighborhood One . Ground water , however , will be encountered in most of the lower areas adjacent to Refugio Creek . 1/ Seismic Safety Element - Public Hearing Draft , Contra Costa County - Planning Draft, August 1975 . III- 61 ��Seismic : On the basis of past history all of the San Francisco Bay area is con sidered seismically active . As the location and prediction of earthquakes is still not within the technical knowledge of the engineer , estimates of future occurrences must be based on historical activity and statistical probability . Therefore , the three major potential damaging effects in Neighborhood One are discussed below : a. The area studied is about three miles from the Hayward fault zone and about 20 miles from the San Andreas Fault . Both of these fault systems are active and have produced numerous earthquakes . One projection of the active Calaveras Fault passes through the Carquinez Strait near Crockett about four miles from this site . The intensity of the ground vibration is directly related to the distance from the epicenter , magnitude of shock wave , and the physical charac teristics of the foundation soils and rock . Rock generally is considered to be the best foundation material followed by weathered rock , compacted fill and alluvium in that order . Loose sidehill fill constitutes the most hazardous foundation material . A high ground water condition will amplify ground shaking and increase hazards . Reference to the geologic section of this report indicates that this site is underlain with moderate to hard bedrock which provides the best foundation conditions from a seismic standpoint. The lower areas with alluvium present a higher shaking risk . b . Ground Failure: Ground failures during and following an earthquake usually include at least one of the following failures : (1) Landslides (2) Rock Falls ( 3) Subsidence (4) ( 5) Liquefaction Sand Boils ( 6) Ground Displacement The possibility of earthquake induced landslides within this site on the steeper slopes has already occurred . Depending on the size of the shock and the duration it can be assumed that this type of hazard does exist particularly in natural slopes . This hazard increases during those periods of the year that the soil is saturated . III -62 �一 �Rock falls in the natural state do not present a serious hazard , however , if unbalanced grading occurs oversized rock surplus could be generated making this hazard a possibility . Design of grading and balancing of the quantities should be carefully monitored . Subsidence may be a problem in the deep alluvium material in the flat low areas . This , however , is within the design parameters of engineers . Liquefaction and sand boils should not be a problem at the higher ele vations . Loose sand layers were encountered however in Neighborhood One and the water table was encountered in one boring in the northwest portion of the site . This hazard is a probability and a careful review by the soils engineer ateach proposed development shall be made of this item . The preliminary maps by the State Department of Mines and Geology for the City of Hercules submitted in December 1973 show two study zones in the immediate proximity to this site . involved was the Pinole Ridge . The one most directly This was investigated by Cooper & Clark in 1971 and 1974 and this hazard area was removed from the Special Studies Zone map of the State . As no epicenter has occurred within this site and no known faults have been identified , ground fault displacement is not considered a hazard . Soils : The subsurface soil conditions underlying the site vary considerably with the underlying geologic unit . Upper Briones Sandstone - The Upper Briones Sandstone has a soil overbur den generally varying between 13 and 12 feet in depth with soil thicknesses typically less than three feet . The greater depth of soil overburden encountered in this unit is probably related to a greater degree of fracturing of the bedrock in those locations . The soil overburden overlying the Upper Briones Formation consists primarily of medium plasticity , silty clays which are dark brown in color and have high expansion potential. There are also limited amounts of sandy silts and silty sands which are relatively non - expansive . III - 63 �一 一 �All cut and fill slopes shall be constructed no steeper than two horizon tal to one vertical ( 2 : 1 ) . Special grading procedures should be utilized to minimize foundation re quirements for the proposed residential development . The overburden soil materials present in the Upper Briones Sandstone, the Hercules Shale , and the Lower Briones Sandstone consist primarily of highly ex pansive , silty clays although some non - expansive sandy silts are present in the Upper Briones Sandstone and the Lower Briones Sandstone areas . In addition to the expansive overburden soils , the Hercules Shales has significant expansion potential which would require special foundation design if it is exposed at the surface of finished pads . The on- site materials are subject to erosion from surface runoff , par ticularly the Upper and Lower Briones Sandstone units . For this reason , after grading is performed , the slopes may be planted with a suitable ground cover prior to the winter rains to preclude detrimental erosion . Mass grading will be necessary in constructing Neighborhood One . Approximately 70 % of the total area will be subject to some grading acti vity leaving 30 % of the site in its natural state . On the area covered by the tentative map approximately 80 % of the site is to be altered leaving only 30 % in a natural state . Preliminary grading estimates show approximately 1,700,000 cubic yards of earth will be moved to accomplish balanced grading for the initial 164 acre site . yards of earthwork per acre . This averages 9,750 Though precise planning has not been completed for the remaining portion of the study area , if similar develop ment is projected , total grading for Neighborhood One may involve in excess of 4.0 million yards . the initial unit is 70 feet . The maximum cut bank height proposed for The two major fill banks are proposed to be 45 feet high on the tentative map . to one gradient or flatter . All man made slopes will be at a two III -64 ��Hercules Shales - The soil overburden in the Hercules Shale area consists almost totally of a medium to high plasticity silty clay con taining limited amounts of sand . This material is considered to have high expansion potential and generally had desiccation cracks to depths of 1 to 21 feet at the time of our field investigation . Lower Briones Sandstone - The soil overburden materials in the Lower Briones Sandstone unit generally consist of approximately two to three feet of a medium plasticity silty clay with limited amounts of sand . This medium to high plasticity silty clay is con sidered to have high expansion potential and was generally des iccated throughout its entire depth . The central portion of the site consists primarily of a geologic unit mapped as Alluvium . The Alluvium is fairly thin in thickness , and the underlying bedrocks , Hercules Shale and Lower Briones Sandstone , were en countered at depths ranging between six and 24 feet . Except for the areas adjacent to the Hercules Shale slopes , the surficial material in the valley Alluvium consisted primarily of clayey sands and sandy silts of nil to low plasticity and with slight to low expansion potential . Under lying this surficial stratum were interbedded sandy clays , clayey sands and sands . The Alluvium materials ranged from firm to stiff for fine grained materials and loose to medium - dense for coarse grained materials . Dumped garbage debris was encountered along the east bank of the in cised stream channel near the middle of the site . The depth of this material is typically less than four feet although the depth may increase where it has been pushed over the bank of the adjacent stream channel . 5/ Geotechnical Investigation , Wanten Hills # 1 , Hercules , CA Centex Hines , Berloger , Long & Assoc . III -65 Feb. 7 , 1975 - ��Hydrology * All of Neighborhood One is drained by the East branch and the Main branch of Refugio Creek . The runoff volumes are high due to steep slopes and impervious ground cover . Using the drainage areas indicated by Contra Costa County and Toups Engineers , the runoff values are computed in the table below for the Main and East branches of Refugio Creek . Runoff of Refugio Creek Affecting Neighborhood One Main Branch Basin Main Area 1519 С AC .52 799 ilo i25 i100 639 800 960 East Branch Basin East Area С 400 * Storm Water Runoff AC .8 320 ilo i 25 i100 256 320 384 Impacts and Mitigation Measures Toups Corp , October 24 , 1975 III - 66 ��Based on the " Rational Method " utilized in the Chart above , urbaniza tion will increase the flow in the East and Main branches by 30 % . Thus the existing flow of 895 second feet will be increased to 1284 second feet. In the East Branch Hercules Inc. proposes to build a 54 inch storm drain . Without benefit of the design data and assuming a " n " value of .012 and a slope of .005 foot per foot, the capacity of this pipe is approximately 150 cubic feet per second . This is roughly one half of the flow anticipated in a design storm and flooding of the streets and railroad culvert will occur . In the Main Branch urbanization will increase the flow from 639 to 960 cubic feet per second or approximately 320 second foot increase and this will cause flooding or ponding as the proposed culvert under Sycamore Avenue ( S.D. Line " C " ) does not have capacity for this flow . It is estimated that elevations below 50 feet U.S.C.S. datum will be affected . This area generally has been designated as a commu nity park in the City General Plan . Agreement by the landowner to this ponding was a condition of approval of Tract 4719 . While there are areas of unbalanced flow it is within the design limitations Careful attention must be to correct and control these conditions . paid to design to assure adequate capacities of natural channels and designed facilities . Expected Impacts Although there are several potential environmental impacts which may result from any grading activity , it should be noted that the quantity of earth moved does not, of itself, create an adverse environmental impact . It is the final placement of this material and the treatment there of which should be considered . A number of mitigating measures required by HUD in all subdivision development as described in Data Sheet 79G should result in the net effect of the grading and land treatment being minimal. From an aesthetic point of view the initial impacts of grading will be mitigated through the contouring and sculpturing of finished grades to blend the man - made cuts and fills into the existing terrain . In this manner the short- term scarring of the terrain with its potential erosion and siltation problems will be alleviated . In addition , the loss of the natural vegetative cover will be offset in the long run as the introduced landscaping matures creating a cover which is much more dense . Finally , the development will include silting basins , energy dissipators and other appropriate devices if deemed necessary to minimize the silt carried in runoff . III -67 ��As noted earlier , no active faults are believed to exist in the vicinity of the City of Hercules . The soil and geologic conditions of the site , coupled with grading activity has the potential to create unstable slope conditions if not properly diagnosed and treated - particularly in areas subject to slides and creeping . and major damage. If not mitigated , structures could be subject to slipping Fortunately , these serious impacts can be successfully mitigated by a number of planning and engineering design techniques to the extent that final soil and geologic conditions are stable . To insure these conditions , a detailed comprehensive soil and geology analysis will be completed by a qualified soils engineer for each development phase . Areas of potential geologic hazards will be identified . Following the review by HUD staff in the course of normal subdivision processing , specific recommendations will be made and incorporated into the conditions for approval of the particular tentative map . Such measures may include ( but , of course will not be limited ) to such items as - the removal of minor slide areas buttressing the toe and / or removal of the top of slide prone areas removal of expansive soils and replacement with properly com pacted fills . storm drain design which will keep storm runoff and irrigation water off potentially weak slide slopes . incorporation of any geologic hazard areas into natural , low use open space areas . Assurance that the specific recommendations incorporated into the conditions of approval of the tentative map have been complied with by the developer will be provided by means of the regular processing system which is required in any subdivision approval by HUD / FHA including certifications of engineers . III -68 ��The higher volume of runoff anticipated as a result of the development of Neighborhood One has the potential to increase erosion and siltation because of the increased velocity and loss of natural ground cover . This impact will be offset in part by the reduction in steepness and height of the natural slopes . Further mitigation will be obtained by the proposed landscaping efforts which include hydroseeding with ground cover shrubs and trees together with irrigation in conformity with the City of Hercules Grading Ordinance . These efforts will stabilize the hillside, retain moisture , prevent erosion and enhance the natural scenic beauty of the site . It should be noted that irrigation of the landscaped areas will enable the develop ment of Neighborhood One to probably have a net long term beneficial impact of raising the ground water level in the natural watercourses . This should improve the vegetative quality of those natural areas thereby having a further secondary beneficial impact on the remaining wildlife . Finally , a storm drainage system has been designed and will be constructed which will collect runoff in streets and in an underground system which will drain any significant water volumes off the slopes significantly reducing impurities from entering the ground water . III - 69 ��CULTURAL RESOURCES A review of the National Register of Historic Places and a telephone conver sation with the Department of Parks and Recreation , State Resources Agency has revealed that there are no national or state historic landmarks or sites in or near the area proposed for development into Neighborhood One . Field trip observations have further confirmed that there are virtually no structures in the area that could be nominated for inclusion in such lists . The developer contacted the Department of Archeology at the University of California at Berkeley and was informed that there were no known or suspected archeological sites within or near the parcel proposed for development. It is highly desirable to preserve the integrity of any such site should it be uncovered during grading . Therefore , the sponsor has agreed as a condition of HUD approval that upon locating any significant traces of such sites he will immediately contact the Department of Archeology , University of California or a like indepen dent archeological society and HUD to ascertain the significance of the discovered site and what appropriate further actions might be indicated . This precaution should offer sufficient protection to any unknown archeological areas which may exist. Affirmative Marketing Plans have been approved by HUD for the first two sub divisions currently under construction in Neighborhood One . Similar plans will be submitted by the developer for HUD approval for the remaining develop ment in the project area . III - 70 ��Part IV A. ALTERNATIVES TO THE PROJECT ACTION Possible Different Site Locations Before the present site for Neighborhood One was selected , a search was made by the developer for potential sites to be developed into major residential areas in Western Contra Costa County The area comprising Neighborhood One was chosen because the single owner was able to provide available and reasonably priced land with adequate terrain for growth and development . The area acquired was deemed most suitable of any available . It was located within the corporate limits of an already existing general law city with the legal capacity to guide, plan and control the urbanization process . B. Alternative Uses Uses other than residential have been considered and rejected by the City Council. The intended use is embodied in both the General Plan for the city and the Municipal Zoning Ordinance . Neither industrial nor heavy commercial uses have been seriously considered for this site because of the numerous negative impacts which such development would cause and the fact that a substan tial amount of industrial land with more amenities is presently available in the Bay Area . C. Sizes and Designs The one real alternative density / coverage system possible for Neighborhood One would be higher density , apartment - type complexes . 1. This was rejected because : Higher design densities would impose an extraordinary impact on the major supportive facilities 2. exclusively multi- family ( traffic and sewer ) . The market absorption rates for this type of housing would cause an extensively protracted development period . 3. Lack of potential for variety and diversification in housing types plus the lack of any form of public transportation during initial stage of construction . IV - 1 ��-- D. - No Project The no action alternative is not a reasonable one in this situation . HUD approval is relevant only to approval of the project for The final Environmental Impact mortgage insurance purposes . Report prepared under State of California Environmental Quality Act guidelines has been completed and some development is already under way in the project area . The decision to proceed with a residential development is entirely that of the developer within the confines of the General Plan and Zoning Ordinance of the City of Hercules although HUD's decision could have an indirect bearing to the extent that the feasibility and marketability of this undertaking depends upon the availability of HUD/ FHA mortgage insurance . IV - 2 ��PART V PROBABLE ADVERSE ENVIRONMENTAL IMPACTS WHICH CANNOT BE AVOIDED SHOULD THE PROPOSAL BE IMPLEMENTED 1. The development of Neighborhood one will take land out of grazing and open space and convert it to urban usage . The actual design of this residential neighborhood will enable a considerable amount of the land to remain in open space , some of which may be landscaped in the future . 2. One adverse impact that cannot be avoided through implementation of the project involves overall air quality . Major transportation in this area will be by automobile , and every new home occupied will generate traffic which will result in some air pollution . Mitigating actions in this respect could include the development of " cleaner " cars , the establishment of a local transit system , establishment of no - growth policies , etc. while all of these could help , they would require action of bodies considered outside the scope of this study . Thus , some deterioration of air quality is viewed at this time as an unavoidable impact resulting from this action . It should be noted , however , that the carbon monoxide expected to be generated by the residents of Neighborhood One at full development will be well below the levels considered to be unacceptable . During construction , it is expected that some dust will be created as a result of vehicular movements on unpaved areas ; however , this impact will be temporary and of short - term duration . 3. In order to extend adequate water service to the project , major new water storage and distribution facilities will be required , including pipelines , pumping facilities and storage reservoirs . There is , of course , a potential financial impact on the East Bay Municipal Utility District and its customers resulting from the capital outlay for these new facilities . However , new regulations recently adopted by EBMUD now place most of the financial burden for constructing these facilities upon the developer . Water storage reservoirs may cause an adverse visual impact . The total water demand of the fully developed project can be expected to have a minor , long - term negative impact on the EBMUD water supply system furnished from the Sobrante Filter Plant . The total estimated project water consumption of 0.78 mgd is approximately 0.37 % of the 211 mgd average daily water demand of EBMUD . V - l ��4. The development of Neighborhood One will result in an adverse impact upon the recently constructed Pinole sewage treatment plant by utiliz ing a major portion of its remaining capacity . This remaining capa city is being obligated on a first - come first - served basis under a joint powers agreement between the two cities of Hercules and Pinole . The overall problem of sewage treatment capacity at the Pinole plant may be mitigated if the alternative recommended in the Wastewater Management Program is approved as now scheduled for adoption vote in March 1976 by the six cities and sanitary districts involved . Approv al of the program will obligate property owners in both Pinole and Hereules to finance additional costs of sewage treatment beyond those incurred in the construction of the initial plant in 1973 . 5. The extensive grading proposed in the development of this project will increase erosion due to the increase of slope ratios and the temporary removal of vegetation . At the same time , proper grading will correct many natural steep slopes which are involved in soil creep or sliding which will produce a more stable condition . Mud slides could be a problem if heavy precipitation occurs prior to the establishment of adequate ground cover . 6. The development of Neighborhood one could accelerate the development of other lands both in and out of the corporate limits of the city of Hercules . Whether or not this is an adverse impact depends upon one's point of view . Population growth in the Bay Area dictates the eventual urbanization of these lands . This development will merely advance the time that the surrounding lands will be developed . V -2 ��Part VI RELATIONSHIP BETWEEN LOCAL SHORT - TERM USES OF MAN'S ENVIRONMENT AND THE MAINTENANCE AND ENHANCEMENT OF LONG - TERM PRODUCTIVITY Long - Term commitment of agricultural grazing land or other vacant land use to permanent urban residential use . Short - term uses of man's environment consist of construction related activities such as noise from construction activities , dust , dump trucks , earth -moving equipment, etc. All of these activities will result in a short- term negative impact to the environment. There will be loss of vegetation cover and surface soils during construction . Upon completion of construction these effects will be reduced and virtually eliminated although the loss of wildlife will be permanent in the areas not left as open space . Long - term commitment of infrastructure services , ( water , energy , etc. ) to support housing developments for an average life expectancy of 30 - to 50- years . Short - term creation of jobs during construction . In terms of " cash - flow " this results in a short - term positive impact within the area . Air pollution associated with vehicle emissions will continue and increase on a long - term basis as population increases . The level of air quality will be further complicated by emissions from power mowers , motorcycles , furnaces , etc. that are an integral part of residential living . - The development of this site as a residential neighborhood is consistent with long - term planning for the area which recognizes its eventual conversion to urban uses . The long - term requirements of an expanding urban community are reflected in the provisions made through careful plan ning for open space and recreation , VI . schools , etc. ��The development of this parcel into residential urban uses will result in the permanent loss of agricultural grazing and vacant open space lands with the resultant loss of vegetation cover and wildlife habitats . These losses are somewhat minimized by the existence of a considerable amount of land with some of which are committed to permanent open space similar uses nearby use such as the East Bay Municipal Utility District and East Bay Regional Park lands plus numerous undevelopable areas which will of necessity remain in open space . The balance , however , the development of Neighborhood One will provide some 1680 moderately - priced single - family detached housing units in a favorable location in the San Francisco Bay Area . This is a favorable long -term impact which will assist in fulfilling western Contra Costa housing demand . Related to this favorable balancing impact is the fact that many of the families moving into these new homes will , in turn , add their own homes and apartments to the inventory of available housing in the Bay Area . Since some of these housing units will be lower priced on the resale market , a certain benefit may accrue to lower - income families seeking housing . Finally , this area is being developed as a full neighborhood unit and not in a piecemeal fashion which has often resulted in disjointed and barely com patible areas . Its location within an incorporated city has resulted in better standards of planning than might otherwise have been available . VI-2 ��--- PART VII . As IRREVERSIBLE AND IRRETRIEVABLE COMMITMENTS OF RESOURCES WHICH WOULD BE INVOLVED the development of Neighborhood One proceeds , the following permanent commitments of resources are identified as accompanying each subdivision : A long - term commitment for some 30 - to - 50 years of land presently in grazing use or vacant use to urban use as each subdivision develops . This also includes the destruction of habitats as well as the flora and fauna presently existing in the undeveloped areas . A long - term public financial commitment on the part of local govern ment to provide necessary services to support each subdivision . This includes such services as fire and police protection , sewerage disposal and ultimate treatment as well as solid waste pick up and land fill sites for storage and /or disposal of waste by - products. A long - term public financial commitment on the part of the Federal Government via the Federal Housing Administration (FHA ) or Veterans Administration ( VA ) for mortgage backing or subsidies associated with certain types of housing developments. Such commitments may present irretrievable financial losses should foreclosures occur . Natural resource losses associated with site preparation and con struction in any subdivision or development. These include such things as timber , cement, sand , gravel, etc. , as well as manpower and energy needed before , during , and after construction . Site grading , leveling and / or filling are also required . Loss of views , vistas and openess as land uses change from rural and undeveloped to urban and developed . Modification of the ecological balance between such natural events as precipitation , ground run - off , evaporation and ground water storage as surface impermeability is reduced due to construction . VII . ��PART VIII. RECOMMENDED ACTION ON PROPOSAL After review and study of the various findings of this Draft Environmental Impact Statement it would appear that from an environmental point of view , the development of Neighborhood One should proceed , assuming approval of both the Draft and Final Environmental Impact Statements , provided that all other HUD processing requirements are met .
