The Danvilla 2005 General Plan land use designations would permit between 286 and 532 new'residential units. The cumulative impacts of this new development was addressed in the EIR prepared for the General Plan. The Specific Plan provides detailed development standards and design guidelines that reflect the unique characteristics of the area. These standards and guidelines must be addressed in the design, review, and approval cf development plans pro- posed within the area. 7. Findings On the basis of the Danvilla 2005 General Plan EIR which con- sidered&he impacts of redesignating the study area from Country Estates to more intense residential land uses and Public and Semi Public uses and was certified on 10/5/87, and the Initial Study, and the mitigations imposed upon the Specific Plan Area as a result of the Initial Study, the Town of Danvilla finds that the Old Blackhawk Road Area Specific Plan will not result in significant adverse environmental impacts. Certain potential site-specific impacts must be considered in the environmentaI review of development plans that are submitted within the area. Mitigation Measures Mitigation measures applied to the Specific Plan are described in the text of the Initial Study (attached) ECONOMIC AND PLANNING SYSTEMS INITII~2T~DY Old Blackhavkhd2peciZtc Plan Prepared by: Town o~ ~anvillm 1RT~R Iq"ITTR'T';.,I ~ · RFRL"'FT'F'%" ("'AI TT¥'IRl%T'IA Q~"'71('1 · PHt'~l%TI;' (,,clr,% 1;~1.01Q,(I Initial Study June 9, 1988 The California Environmental ~uality Act (CEQA) recommends the use of an Initial Study to determine if a proposed project may have adverse environmental affect.

The Initial Study enables the lead agency to determine potential environ- mental impacts and, where possible, alter a project or include mitigation measures such that potential impacts are avoided. The Initial Study should lead to a definite conclusion regard- ing what level of additional environmental review is required. The options include: o Negative Declaration (No significant impacts or impacts mitigated by project design and/or components) o Mitigated Negative Declaration (Potential significant impacts fully mitigated by conditions applied to the proposed project) . o Preparation of an EIR (Requires project scoptng, issuance of Notice of Preparation, preparation of a Draft EIR, responses to comments, and preparation of a FinalEIR) This Document contains the Initial Study conducted for the Old Blackhawk Road Area Specific Plan, a discussion of potential impacts, and mitigation measures associated with these impacts. Subsequent development plans proposed in the area will be sub- Jected to environmental review and required to incorporate all mitigationme~sures identified both herein and in the Final EIR for the Danwflle 2005 General Plan. 1 Initial Study June 9, 1988 The Old Blackhawk Road Area Specific Plan is being prepared in direct response to the ~*nv.41~e ~005 Gener-l P~n, which was adopted in October, 1987. The General Plan included the fol- lowing language regarding the Old Blackhawk Road area= ePrior to the development of this am and in order for fur- ther development to ~ccur, a Specific Plan shall be prepared for the antire Old Blackhawk Road Area to determine appropriate circulation, ~pan space and recrea- tional amenities, housing types, etc. The Specific Plan should also include a comprehensive traffic study which identifies any capacity related improvements which may be necessary to maintain acceptable levels of service. The Specific Plan shall be prepared and submitted with the first application for rezoning of the area." The General Plan redesignated the Old Blackhawk Road area for a variety of residential densities and a public-semi-public use as follows: ' Public and Sext-public The most significant holding in the area is the 11 acre site owned by the Catholic Church. The site, located at the comer of Comino TassaJara and Old Blackhawk Road, is designated Public and Somi-public. Currently vacant, this property is expected to be developed with school and church facilities at some point in the future. MUltiple Family Residential - L~wDsnsity A 19 acre area is designated multiple family residential surroun~Wthe Church site on two sides. This area is expected to build-out with townhouse residential tmi~s. Single/Multiple Family Directly behind the MUltiple Family Residential area is 33 acres designated for single/multiple family units. This area is expected to build-out with spario homew residential units. Single Family Residential -- Low Density The remaining 21 acres, located northerly portion of the area, and westerly across Old Blackhawk road, are desig- nated for low density single family units, up to three units per acre. 2 Initial Study Jtlne 9, 1988 This land use ahange was determined to result in an increase in residential units in Danvilla between 286 and 532 tittits. The c~amulative impacts of this potantial additional develolment was addressed In the EIR prepared for the Danvilla 2005 General Plan, adopted in Ootober 1987. 3 P/KkTECT DESC~TP'I'~ON Initial Study J~tne 9, 1988 The Old Blackhawk Road area is a residential neighborhood located on the eastern edge of the Sycamore Valley in Danvilla. The Old Blackhawk Road Specific Plan is intended to assist the implementation of the n~nv4~le 9005 Generml P~sn for this area. The area is situated along Old Blackhawk Road, a remnant cre- ated when the new Blackhawk Road was constructed to the east of the area. The area is of a narrow triangular configuration running roughly north-south, approximately 84 acres in size. In 1988, the area was divided into 30 parcels which ranged in size from 1.1 to 11.1 acres. West of Old Blackhawk Road lies the Wood Ranch Project, a large development with a mix of development types, including medium single family units, low density single family units, and open space. The Wood Ranch_ is expected to build-out between 1988 and 1995. The sloping eastern boundary of the area is occupied by a 145 unit condominiumproJect and the Blackhawk executive offices. These uses, because of topography, overlook the area, creating a significant visual element. Proposed Project A specific plan is one type of regulatory tool which may be used by local government to guide community development. A specific plan provides a bridge between the General Plan and the zoning ordinance, which regulates individual project devel- opment plans. Overall guidance for physical development is pro- vided by the General Plan, which sets forth planning goals, policies, and implementation measures for the entire Town. The Old Blac~awk Road Area Specific Plan provides more detailed development standards and design guidelines that reflect the unique characteristics of the area. These stan- dards and guidelines must be addressed in the design, review, and approyal of development plans proposed within the area. Specific Plans are prepared under the authority of Sections 65450 through 65457 of the Government Code of the State of Cal- ifornia. The detail of environmental review that is achievable for specific plans is limited by ~he fact that site-specific impacts associated with actual development projects are not identifiable. CEQA contains the following language regarding aplan" projects: 4 Initial Study June 9, 1988 'An EIR on a project such as the adoption or amendment of a comprehensive zoning ordinance or a local general plan should focus on the secondary affects that can be expected to follow from the adoption or amendment, but the ZlR need not be as detailed as an EIR on the specific construction projects that might follow.~ (Sec. 15146 (b)) Individual development projects, submitted in accordance with the Specific Plan, will require rezoning to P-1 (planned unit development zoning) prior to preparation and review of develop- ment plans. The rezoning actions and review of development plans will be subjected to further environmental review, focus- ing upon the potential site-specific impacts that may result from development. Initial Study June 9, 1988 ENVIRONMENTAL EVALIIATION The following environmental evaluation includes those items identified in the CEQA guidelines that should be considered in an environmental review of a project.

Initial Study J~ne 9, 1988 Yes Maybe ~ _X_ 12 DISCUSSION OF ENVIRONMENTAL EVALUATION Initial Study June 9, 1988 Subdivision activity requires grading which will disrupt soil and lead to increased coverage. The amount of earth movement which will occur will be relatively minor due to the relatively flat terrain in this area. No other earth-related impacts are consid- ered significant. Mitiaation Measures Sensitive soil areas, including moderate slopes on the east side of the area and the flood plain along Sycamore Creek will be excluded from development and included in open space uses. Set- backs, yards, and open space buffering requirements will all tend to limit coverage of the site. Additionally, development will be subjected to Danvillees Grading Ordinance, which is designed to minimize impacts of grading. Water TmDactAnalVsts Increased coverage of the site due to development could result An increased runoff in Sycamore Creek. Low lying portions of the site are presently subject to minor flooding during peak flow periods. The relatively small size of the area in relation to the watershed should limit the significance of such potential impacts. Sycamore Creek is maintained by the Contra Costa County Flood Control and~ter Conservation District. The District has made improvements to the channel to accommodate planned development in the watershed~ however, the Old Blackhawk Road Area was calcu- lated at its current densities. M4t4gat~on Me~s-res l) The watershed and channel improvements should be managed in accordance with District standards. Danville should encournge the District to assure thnt peak flows entering the Town are mitigated to the full extent possible by the on-site facilities within the Blackhawk Project. Apparently, these facilities exist but have not been adequately maintained or used. 13 3) Initial Study June 9, 1988 Development within the site should be located away from flood prone areas. This can be accomplished by showing open areas on the land Use Map and also imposing conditions during the P-1 development plan process. The potential increase in runoff, ~ver and above current con- ditions should be calculated as part of preparation of a drainage plan of the site. This study should be completed during the first phase of development of the site. The study should result in a recommended drainage plan for the site and any downstream improvements that may be required to accom- modate increased flow. Plant Life TmDact Analysis The site has been in agricultural and more recently, rural residential use. Accordingly, vegetation predominately includes non-native grasses and exotic trees and shrubs. Native vegeta- tion does exist along Sycamore Creek, including a significant Nheritage tree", a large live oak. Mitigation Measures 1) Riparian vegetation should be preserved to the maximum degree possible in its present natural condition. This objective can be achieved by imposing building sethacks along the Creek and limiting structural drainage improvements to the channel to those that do not remove or damage existing trees. 2) The large Heritage Oak tree should be protected. This can be accomplished by placing the tree within an open space area and limiting grading within the treats drip line. 3) landscaping within the project site should emphasize the uses of native species. This can be accomplished by requiring such species when landscape plans are prepared as part of development plans. Soise T~DaCt ~naq Vs4 s Increased development and associated traffic levels will increase noise within the site. These new noise levels will be typical of residential areas and not be excessive. 14 Initial Study June 9, 1988 M4 t~ gat~ on Meas,,res 1) Danville*s Noise Ordinance will be administered in the area. This ordinance will set standards and regulate noise levels. 2) The Camino TassaJara parkway design includes construction of sound walls along those portions of the road where residen- tial development will be in close proximity. Such · sound wall will be developed where appropriate along frontage por- tions of the site. land Use vmpactAnalWsis The Specific Plan is one step required for development of the site, in accordance with the General Plan. Development of the area will alter current land use patterns and result in sig- nificant changes to the landscape. Existing rural residential development will be replaced with a combination of public uses, single family and multi-family residential uses. At oral of approximately 400 units may be developed. The actual'timing of this new development is uncertain. The first phase of develop- ment, representing over S0 percent of the development capacity, may occur in the near term, over the next several years. The balance of development is likely to occur in smaller projects over a longer term. The phasing of the development and the diversity of uses proposed may create incompatibility between new uses and between develop- ment in the first phase and later phases, since existing resi- dents may choose to remain indefinitely. N4t~g~t.~onMSsures The Specific Plan should contain development standards and design ~uidelines that provide mitigation measures which address land use incompatibility. All mitigation measures An the Danville 2005 General Plan EIRwhich address impacts associated with the change in area land use should be incorporated into the consider- ation and approval of individual P-1 applications. Transportatlon/CLrculatlon nett4ng The Old Blackhawk Road area is located on the easterly edge of the Sycamore Valley with access to central Danrills and 1-680 provided by Camino TaesaJara and Sycamore Valley Road. Access to 15 Initial Study Jth~e 9, 1988 Camino TassaJara is provided by Old Blackhawk Road, a rural road providing the only point of access to the area. The northerly extension of Old Blackhawk Road was closed to prevent through traffic from using the road. Currently traffic on Old Blackhawk Road is limited to that generated by the 30 homes l~cated in the area. Existing trip generation My range from 200 to 300 trips per day. The area suzToundingthe Old BlackhawkRoad area, including the Sycamore Valley end the Crow Canyon Corridor area to the east have been the subject of a great deal of planning end development activity over the past few years. Increased traffic from the Old Blackhawk Road area must be viewed cumulatively with this area- wide development. Traffic Studies AdoDted bv Reference The Old Blackhawk Road Area was included in two recent comprehen- sive traffic studies of traffic impacts in the Camino TassaJara and Crow Canyon corridors, the Crow Canvon Corr.~dor TT~nsDorta- t.~on Study, (TJKM, 1986 updated 1987) (hereafter refe=red to as the '1986 study'), end the Camino Tassa~ara General Plan ~end- ~ent ~nv.~ronmental TmDaCt Repor~c, (Darwin Myers Associates with TJKM, 1988) (hereafter referred to as the Camino TassaJara GPA EIR). These two studies provided both impac~ analysis and mitigation measures for the cumulative traffic impacts of all proposed Crow Canyon corridor projects including the development permitted by the Danvilla General Plan which permitted a theoretical maximum of 532 units in the Old Blackhawk Road area. The Camino TassaJara GPA EIR assessed the environmental impacts of proposed general plan amendments in the Crow Canyon corridor area of Contra Costa County, Danvilla, end San Ramon. The Camino TassaJara GPA EIRtraffic analysis was essentially enupdate the 1986 Study. The following paragraphs describe the conclusions of these studlegS. The 1986 Study analyzed the off-site traffic impacts of a number. of proposed developments (listed on Figure 1). Since the comple- tion of the 1986 study, these proposed projects have been the subject of numerous public hearings, during which the original project densities were reduced. Traffic forecasts in the 1986 Study were provided for two lend use scenarios. mLand Use Scenario 2' included existing develop- ment, approved development, and development that could be allowed under existing General Plan designations, but excluded additional development being proposed in the Corridor. mLand Use Scenario 3" 16 Figure 1 RF~ID~NTI~L LaND USE MSUKPTIONS Crow Canyon Corridor Projects Initial Study June 9, 1988 Number of Residential Units ProJect 1986 study cu:Tent diZZerence Projects studied in 1986: o Morgan Ranch o Shadow Creek o TassaJara Estates o TassaJaraRanch o Vista TassaJara o West Branch 265 213 -52 480 429 -51 200 117 -83 990 820 -170 240 210 -30 809 668 -141 Subtotal, 1986 projects 2,984 2,457 -527 Additional projects studied in TassaJara GPA EIR ProJect Scenario: o Bettencourt Ranch o Hansen/MrackArea o Haskins Parcel NA 470 NA 80 NA 60 610MAX Subtotal, GPA Project EIR &~ditional projects included in Camino TassaJara GPA Cumulative Scenario: North of Camino TassaJara Old BlackhawkRoadArea TassaJara Lane area 3,067 NA 48 NA 400 NA 235 683 Grand Total Cumulative Scenario 3,750 Source: Conera Costa County, Town of Danville, Economic and Planning Systems, TJKM 17 Initial Study June 9, 1988 included all of "Land Use Scenario 2" plus the new projects for a total of 2,924 proposed dwelling units. Both scenarios assumed build-out of the Tri-Valley general plans, as well as A BAG 2010 lend use for the balence of the nine-county Bay region. The 1986 study recommended specific mitigation measures for traf- fic Zorecasts associated with Land Use Scenario 3. These mitiga- tion.measures:were designed..~o provide Level of Serviced ~pera- tions throughout Denyills end Sen Ramon. !t~tigation measures included widening Crow Canyon Road from two lenes to four lenes between Canyon lakes end Camino TassaJara, as well as a number of intersection improvements. The Camino TassaJara GPA SIR evaluated the environmental impacts of development proposed for the TassaJara Estates, Bettencourt Ranch, end the Hansen/Mrack area. For traffic analysis purposes, two development scenarios were analyzed for these projects. The first scenario, referred to as the "GPA Scenario", included the development of 670 dwelling units in these projects in addition to the 2,457 units from the other projects evaluated in the 1986 Study, for a total of 3,067 units. e Non-residential development also assumed in the enalysis unincluded the following proposed uses: o TassaJara Ranch: 80,000 square feet of office uses, 210,000 square feet of retail uses; O West Branch: 30,000 square feet of service commercial uses, 20,000 square feet of office uses, 100,000 square feet of retail uses. The second scenario evaluated, referred to as the "Cumulative Scenario", assumed the development of 48 additional residential units on the Wood Ranch north of Cemino TassaJara, 235 additional residentialj~its in the TassaJara Lane area, 400 additional residential units in the Old Blackhawk Road area, end finally, development of 100,000 square feet of office space at the Wood Ranch Headquarters. Both scenarios assumed build-out of current general plans in San Ramon, Danwills, Dublin, Pleasanton, end Livermore. ABAG year 2010 land use assumptions were assumed for beth scenarios within the balence of the nine-county Bay region. T~pact A~a~ys~s The capacity of roadway links in a network is usually limited by intersections, since these are where the slower turning move- ments, merging maneuvers, end stop-end-go traffic conditions 18 Xnitial Study ~une 9, 1988 usually exist. The primary focus of the 1986 Study and the Camins TassaJara GPJt EIR, therefore, was intersections ·long the major arterial roods serving the area. The Canine TassaJara GPA IIR analysis of the project scenario concluded that after the construction of racehanded improvements and mitigations, all study intersections would be expected to operate at or better than LOS D. Recommended improvements are discussed in detail in the 1906 study. These-.improvements include those planned prior to the 1926 Study as well as addi- tional improvements that were identified as mitigation measures in the 1986 Study, including the improvement of the intersections of Blackhawk Road and Canine TassaJara, and v-1 Capitem Drive and Crow Canyon Road. A February 1987 update to the Crow Canyon Corridor Transportation study included a discussion of potential road widenings attributable to proposed projects (including the Old Blackhawk area) not studied in the 1986 study. These projects were sub- sequently studied in the Camins TassaJara GPA SIR. The discus- sion in the 1987 update is compared to findings from the Camins TassaJara GPA SIR below. The February 1987 update to the Crow Canyon Transportation study indicated that wadditional development beyond the 2,984 Land Use Scenario 3 dwelling units in the corridor area would necessitate widening Crow Canyon Road from four to six lanes between Camins TassaJara and Alcosta Boulevard." The Camins TassaJara GPA SIR analysis concluded that the widening was necessary only between E1 Capitem Drive and Crow Canyon Road. The 1987 update also stated that eAdditional development in the corridor area east of Blackhawk Road/Crow Canyon Road would also require widening from four to six lanes on a portion of Sycamore Valley Road east of X-680." This improvement is currently under Finally, the 1987 update indicated that *Depending on the loca- tion, timing and magnitude of proposed Sycamore Valley develop- sent, road widenings from four to six lanes would be required on Sycamore Valley Rood east of 1-680, and on Camins TassaJara between Old Blackhawk Road and Crow Canyon Road.' The Canine .TassaJara GP~ XlR~ncluded that. the location, timing andsag- nitude of proposed cumulative scenario development necessitated both intersection improvements and widening of · portion of Crow C~nyon Road, burner additional road widsnings on Sycs-ore Valley Road or Casino TassaJara. Projected daily traffic volumes attributable to the Cumulative Scenario (which includes the Old Blackhawk area) are, as would be expected, generally higher than GPA Scenario traffic volumes. 19 Initial Study June 9, 1988 Additional development in the Cumulative Scenario beyond that assumed in the GPA scenario would occur principally along Camino TassaJara between Cr~w Canyon l~ad and Sycamore Valley l~ad, which would sustain significant increases in average daily traf- fic volumes. At virtually all study intersections, in beth the A.M. and P.M. peak hours, the Cumulative Scenario Volume-to-Capacity ratios are equal or are greater that the GPA scenario figures. However, after the construction of the additional intersection improve- manes, the Camino TassaJara GPA EIRconcluded that all study intersections would be expected to operate at or better than LOS D. It is important to again clarify that these projected intersection operations assumed numerous capacity-related improvements throughout the study area. Prior analysis of traffic impacts attributable to corridor area development, including the 1986 study, have identified numerous roadway improvements necessary to mitigate expected impacts. The 1986 study provides a detailed summary of planned improvements in Conera Costa County, Danvilla, and San Ramon, and describes addi- tional mitigation measures along Crow Canyon Road. T~e public hearing process included the execution of a Joint Exercise of Powers Agreement (JPA) between Conera Costa County, Danvilla and San Ramon. The intent of the JPA is to insure funding for 21 road improvement projects identified as mitigation measures in the 1986 study and other plans and studies. Additional mitigation measures were identified as part of the Camino TassaJara GPA EIR. ~Development of the Old Blackhawk area (in conjunction with other proposed corridor projects) would necessitate construction of the mitigation measures identified in the Camino TassaJara GPA EIR as well as those documented in the 1986 study. These mitigation measures, when combined with the improvements documented in the JPA, would result in LOS D (indicating~lerable delay) operations on all study area road- ways and at all study area intersections. The Specific Plan recommends additional residential development for the Old Blackhawk Road area of approximately 400 units, a 25 percent reduction of the theoretical maximum development of 532 evaluated in the Cumulative Scenario of the Camino TassaJara GPA ErR. This reduction in units will have a corresponding reduction in vehicle trips generated from the area, meaning that traffic volumes will be less then originally forecasted. Figure 2 illustrates the traffic volumes that are expected from full development of ~he area in accordance wi~h the gpecific Plan.

Site specific mitigation measures include= 1) Funding. Contribution toward further funding of the improve- ments partially funded by the TassaJaraArea Transportation Fees J.P.A. including Diablo Road widening, signal installa- tion, park and ride facilities and undergrounding of major utility lines. Currently, these improvements are as of yet 69% unfunded. 2) Street Width. Current plans show 40' right-of-way. If the streets are 30'from curb to curb, then parking should only be allowed on one side or prohibited. Preferably, the street should be 40~ wide with 12~ through lanes in each direction and St parking on each side. Minimum width should be 36e. A sample recommended cross-section is attached. 3) Sight Distance. Approximately 250' of clear sight distance should be maintained for traffic exiting cul-de-sacs. All cul-de-sacs, with the exception of the most northerly, meet this criterion. The northern cul-de-sac creates a non- standard angle intersection with the main collector. This angle, when combined with the backyard fences along the main collector, present potential sight-distance problems. 4) Offset Intersections. Offset intersections should be avoided. There are too many conflicting moves that may be unexpected. However, these conflicts may be minor because of low peak aour volumes end high peak directions. 5) Compound Curves. For safer maneuvering there should be approximately 100~ of tangent between reverse c~LTves, end compound curves should be avoided. e) Cul-de-sac radius. Cul-de-sac radius at curb face should be a minimum of 40t. Parking should be prohibited in cul-de-sac by design of pie-shaped lots end close driveways. Public Services vmDactAnalys{s Development of the area will increase damands for public services including police protection fire protection, schools, parks and Initial Study June 9, 1988 recreation, and libraries. These impacts were addressed in the nAnv411e ~005 Genera] Plan xTR. Mtt~ a~t~ on Ne~s-re2 Danvilla has developed or will develop public service capacity to provide at least the existing levels of service to new residents within the Sycamore Valley. These improvements include an expanded police protec~ion plan, new schools (developed in cooperation with the San Ramon Valley Unified School District) and a new library in downtown Danvilla. Utilities T~pact Analysis The area is entirely within EBMUD, which will provide domestic water. The area is partly within CCCSD. Both distric~s have adequate capacity to provide service to the area. Development of the area will utilize capacity of existing water and sewer utili- ties. These utilities were addressed in the n~nv~le 9005 Gen- eral Plan ~TR. ' It will be necessary to construct new lateral water and sewer lines from existing trunk lines located along Cemino TassaJara. M{t~qation Me~s,,res The Specific Plan should require that all development proposed meet the requirements of the special districts serving the area. Cultural Resources TwDaCtAna-.1yaiD Review of general survey information indicates that no prehistoric cultural sites exist within the area. However, recent discoveries within Danvilla suggest that any site located along a creek may contain cultural resources. If such resources exist, developsent in the area could cause adverse impacts. M4 t4 mat4 on Mess-yes The Specific Plan or subsequent project-specific environmental review should require archaeological surveys to be conducted prior to development activity. Initial Study June 9, 1988 Cumulative lapacts · ~pact ~,r~,.1 ys~ s The Specific Plan is one step towards allowing approximately 400 new residential units vithin an area that is presently developed with approximately 30 rural residential units. This additional development will add cumulativaly to traffic and demand for pub- lic services and utilities. These cumulative impacts rare addressed in the nanv.~31e ~005 Gener-l Plwn ~TR. M~t4aation Measures Plans and programs established within the Sycamore Valley Specific Plan, the Sycamore Valley Assessment District, the Dan- villa 2005 General Plan, and the TassaJara Area Joint Exercise of Powers Agreement combine to assure that cumulative impacts of the development will be minimized. 25 u~-~'zst~IZ!iT~ZON Initial Study June 9, 1988 On the basis of this Initial Study the Tc~n of Danvillehas found that the proposed project could have a significant effect on the environment~ h~wever, these significant effects can be reduced to a less than significant status with mitigation measures incorporated into the Old BlackhawkRoadArea Specific Plan, the Danville 2005 General Plan, and ether planning d~-uments and pub- lic facility plans prepared by Danville.

R%CKGROUND In October 1987, Danvilla adopted the Danville 2005 General Plan. The General Plan included a total of 12 "Special Concern Areas" which were identified as areas requiring consideration of special planning issues. Special Concern Area number 4 is the Old Blackhawk RoadArea. ' The Old Blackhawk Road Area is located at the east end of Sycamore Valley, generally at the northeast corner of Camino TassaJara and Old Blackhawk Road. The area includes 83.5 acres of land which has been subdivided into thirty separate parcels. The new general plan amended the land use map for this area, ~ncreasing the overall density from a maximum of one dwelling unit per acre to a combination of four land uses, with residential densities varying from a low of 1-3 units per acre to a high of 7-12 units per acre. The general plan states (page 46) that prior to the development of the area a specific plan should be prepared to determine appropriate densities, housing types, circulation, recreational amenities and open space. In December 1987, the firm of Economic and Planning Systems was retained by the Town to prepare a specific plan for the Old Blackhawk Road area, in accordance with the requirements in the general plan. Specific Plan Process Specific Plans are prepared under the authority of bections 65450 through 65457 of the State Government Code. A Specific Plan is an implementation measure of the general plan which provides more detailed policy guidance for development of an area. It should also reflect the unique physical characteristics of the area which should be considered in later development plans. Like the generalplan, preparation of the Old Blackhawk Road Specific Plan has emphasized public participation. A total of three neighborhood meetings were held in the course of preparing ,the draft plan. Each meeting was preceded by a mailout to each .property owner which included notification of the meeting time and place and information to be discussed at the meeting. Each · ~eeting was artended by 40-50 people. The ~nitial meeting occurred on January 7, 1988 during which the consultant presented the project work plan and specific issues to be addressed in the plan. A second meeting was held on March 3, 1988 at which time four alternative land use plans were presented tothe public and input was sought toward arriving at a preferred plan. The third meeting was held on April 14, 1988 at which time the preferred land use plan was presented and preparation of the specific plan~as discussed. ~pecif:4c PlAn TSSUeS During the course of preparing the draft Specific Plan and conducting the public meetings, a series of issues were identified which were felt to have a major baring on the plan. In some cases those issues involved areas which needed to be addressed in the plan. In other cases, the issues involved constraints or areas of sensitivity which did not need to be specifically addressed in the plan, but rather were assumed as givens. The eight major issues were as follows: O Achieving the higher densities permitted by the General Plan will require land assembly of existing parcels, many of which presently are build upon with estate-residential units. This land assembly process is difficult and costly. O Densities that are proposed are, in some instances, incompatible with one another and, therefore, should be adequately buffered. o The development of the area will not occur simultaneously. Existing residents may remain for years while adjoining properties opt for higher density development. The life- styles of those owners that do not opt for development should be protected. o Development of the area should be compatible and consistent with adjoining developments, particularly the 'Wood Rahch" development, located immediately to the west of the area. O O Traffic generated by the new development must not exceed the capacity of existing and planned road improvements. New develo~nt in the area must contribute to financing additional 'off-tract' improvements that mmy be required by the additional development proposed. The development of the area offers a variety of opportunities to extend trails and provide access to adjacent open space. O Development in the area must meet high-quality design guidelines and development standards consistent with other development in the Sycamore Valley. Specific P~mn Overviev The plan is organized according to the table of contents on page 1. Presently, the plan is in draft form and will be further refined by staff and the consultant prior to the June 13, 1988 meeting. The heart of the plan is the land use map which illustrates the plan sub areas, the major circulation network, open space and recreation areas~ and, the development standards and design guidelines which apply to boththe'overall plan area and the individual sub areas. It is intended that the land use map used together with the development standards and design guidelines will form the basis for consideration and ~ranting of future development entitlements ~ranted within the plan area. P~nn~na Commission Consideration In order for the Specific Plan to be adopted it must be reviewed by the Planning Commission, then referred to the Town Council for final action along with the Planning Commission#s recommendations. For purposes of Planning Commission review, two meetings are anticipated. On Nay 23, the Commission should hear a presentation from the project consultant, open the public hearing to solicit public input, then discuss the plan among the Commission, providing comments and direction back to the project consultant and the Town sta£f. On June 13, the CommissiOn will discuss the plan as amended with previous comments and the negative declaration of environmental effects. Upon closure of the public hearing and completion of Commission discussion, the Commission will then consider approving a resolution recommending adoption of the Old Blackhawk Road Specific Plan to the Town Council. R~COBe~.NDATION Here the consultant presentation, then open the public hearing to consider testimony concerning the draft Old Blackhawk Road Specific Plan. After accepting public testimony, provide input and direction to the Consultant and staff, and continue the mater to June ~ 1988. Att-chments ,Exhibit A - Draft Old Blackhawk Road Specific Plan 'pJCpl7 RESOLUTION 103-87 A RESOLUTION OF THE TOWN COUNCIL OF THE TOWN OF DANVIx.x.~- CERTIFYING THE GENERAL Plan FINAL ENVIRO~AL IMPACT REPORT AND ADOPTING CEQA FINDINGS POR GENERAL PlAN ADOPTION WHEREAS, The Town of Danvilla has initiated a process for preparation and adoption of a General Plan pursuant to government code section 65300~ end 'WHEREAS, the Town of Danvilla Development Services 'Department, acting as lead agency, determined that significant effects on the environment could potentially result from the adoption of the Plan and that an lnvironmental Impact Report would be necessar~ pursuant to CEQA section 15064~ and WHEREAS, a Notice of Preparation was distributed, along with a description of the scope of the Plan, and a preliminary analysis of potential significant lmpacts~ and WHEREAS, said notice was distributed for agency comment on January 6, 1987 with a request that responses be received by the Town no later than 45 days from the date of agency receipt of the notice~ and WHEREAS, those agencies that responded to the Notice' of Preparation, and others, were consulted in preparing the Draft Environmental Impact Report pursuant to CEQA guidelines sections 15080 and 15083~ and WHEREAS, the Draft Environmental Impact Report has been completed, the appropriate notice prepared, and the document circulated for comment regarding its adequacy pursuant to CEQA 15085~ and WHEREAS, The Planning Commission held two public hearings for the purpose of considering oral testimony concerning the adequacy of the graft Environmental Impact Report on January 1987 and Februi~ 11, 1987 as suggested by CEQAgnidelines section 15087 (G)~ and WHEREAS, the review period for the Draft Environmental kmpact Report expired on February 19, 1987 during which period written comments were submitted regarding the adequacy of the qoctment~ and WHEREAS, written and oral comments have been reviewed, evaluated and written responses prepared representing gooa faith, reasoned analysis supported by factual information~ and 1 WHEREAS, such comments and responses, and the draft Environmental Impact Report, constitute the Final Environmental Impact Report for the General Plan~ and WHEREAS, the following potentially significant environmental effects were evaluated in the Initial Study and identified in the Draft 1. Land Use 2. Traffic and Circulation 3. Parks and Recreation 4. Civic Facilities and Functions 5. Library 6. Wastewater Treatment and Disposal 7. Water 8. Police 9. Fire 10. Schools 11. Natural Resources WHEREAS, the Draft EIR evaluated the following impact categories and indicated-ways in which potential impacts could be mitigated: l) land Use - Potential impacts discussed in the Draft ~IR mainly focused upon land use compatibility issues. These problems have been reduced or eliminated by adopting the mitigation measures recommended in the Draft EIR, or deleting the recommended land use change. 3) Traffic and Circulation - The Danville 2005 General Plan will accommodate additional residential and commercial growth that will, in turn, generate additional traffic. Total additional daily vehicle trips generated by existing and future development would be 130,000 daily. The land use changes recommended by the Planning Commission would add approximately 5.2 percent to this future total. With the ~ception of the regional problems (cumulative impacts on 1-680 and other major highways) mentioned above, Danvilla will be able to accommodate projected increases in locally generated traffic if progTam~ed and planned road improvements are completed. Parks and Recreation - Development of additional housing under the Draft Plan and an increased residential population would intensify use of existing public park and recreation facilities ~and would contribute to the existing deficiencies in ~he Town's recommended park and recreation standards. 4) 5) 6) The increased demand for perks end recreation maryices will be met by additional planned perks. The new davalolmant, along with other planned development will contribute to a perk lend dedication fund. The fund, in combination with lend dedications end other revenue sources will finance a series of perk end recreation inproveaents documented in the Draft General Plan section related to Parks, Recreation, end Open Space. Parklend service standards throughout the community will improve as a result of the Plan. Civic Facilities end Functions - Thepopulation growth generated by the lenduse changes proposed by t ha Draft Plan would contribute to demands for civic facilities. While the Draft Plan recognizes Danvilla residents' existing needs for such facilities end anticipates future civic facility needs, cumulative population 9Towth directly attributable to the Draft Plan proposed land use changes would increase these demands slightly. This demand will be offset through the development of new facilities on the Charlotte Wood School Site upon redevelopmane of that property and implementation of policies contained in the General Plan. Library - Potential short-term impacts on the Danvilla Branch Library may occur due to over burdening a facility which already is used beyond its capacity, if population increases occur prior to the replacement of this facility. These impacts could persist until completion oft he new San Ramon and Danvilla Libraries, and, since it is unlikely that housing construction would be delayed solely in response to liM~ary facilities, these impacts say not be mitigated. Eo~ever, since both the Danvilla and San Ramon Libraries are scheduled for construction over the next 4 to 5 years, the existing overcrowding condition should be eliminated. Wastewater.~.f.r. eataent en D spa - Potential short-term d i salt Sanitary Diatrict#s impacts on the Central Conera Cos a existing San Ramon Valley trunk sever say occur during vet weather, If housing development end sever connections occur prior tot ha planned completion oft ha new parallel trunk sever vhichcould accommodate vet vesther floes. These tspacts could be mitigated phasing residential building permits in coordinationbw~th sever construction. The cost of additional collection and/ortreataent facilities required viII be financedbyuercharges end 3 Water - Development of additional housing units permitted by the Draft Plan reclassifications would involve two principal issues: water supply and water delivery. The additional housing could generate a demand for one to three sgdbased on conservative consumption rates of 1,000 gallons per unit on an average day and 3,000 gallons per units on a saxJJumday. District vaterentitlesents would be adequate to accommodate increased demands of this magnitude. s) Police -The Danvilla Police Depax~ment already patrols established neighborhoods of the Town where some of the new developmentpermitted by the Draft Plan's 20 land use changes would occur. lts newly developing armas build cut, however, the Department will have to extend and expand its police protection services. The future population accommodated by the Draft Plan would result in a corresponding increase in calls for services, but this expected increase can be accommodated by the service expansion correctly planned by the Danvillepelice department. Fire - The District has plans to increase its resources, consistent with anticipated growth, including hiring additional personnel at the planned rate of tan people per year for the next five years. In addition, Station 5 was built specifically to provide fire protection to the newly developing unincorporated area within the District's service area. Because the District is planning for future growth, the incremental increase of housing units and people in its service area directly attributable to the Draft Plan would not be expected to result in significant adverse impacts on the ability of the SRVFPD to provide fire protection and emergency ical services to maintain the quality of theBe larvacaB. and 10) Schools - The District expects an enrollment of 15,000 students in the 1986-1987 school year with an increase to 18,000 students in the next five to seven years, The 600 additional studentavhich could beganerated as a result of Draft Plan permitted development would account for three to four percent of existing and expected enrollsants. Since buildout of the land use change areas would occur during the 18-year planning period, not all at once, and because the changes are located throughout the Town, not concentrated in the attendance area of one or two schools, it is not expected that new development allowed by the Draft Plan's land use changes would affect the BRVFPD adversely. 4 These ~mpacts could be mitigated ~y oollecting developer J~pact fees to finance construction of new schools, ll) Natural Resources - Potential reduction In the number and diversity of plant and animal species my result from conversion of natural habitat to developed use. The significance of these impacts c~mld be reduced partially by mitigation measures but could not be eliminated antirely, thus contributing incrementally to cumulative impacts of urbanization throughout the Tmm end region. Potential short and long-term erosion, sedimentmelon, and water quality impacts nay result from removal of vegetation and grading for home construction, provision of access, installation of utilities, and landslide repair. These individual impacts could be mitigated to insignificant levels but still would contribute incrementally to cumulative impacts throughout the Town and region.. WIZREAS, the Draft General Plan contained numerous policies and implementation measure that protect environmental values and mitigate potential impacts of future development~ and, fbllowing review of the Draft EIR and consideration of ~ritten and oral comments and technical responses to these comments, changes and additions to the Draft General Plan were made by the City Council that incorporated additional environmental protection policies and mitigation measures into the policy framework of the General Plan, including the following: l) land Use - Several of the land use changes originally considered have been deleted or modified in order to reduce potential land use compatibility impacts. The more significant land use changes are contained within designated Special Concern areas which require project specific analysis of.~ll impacts at the time of application for rezoning i~order to assure proper impact mitigation. Several policies have also been included An the General Plan which addresses the need for land use compatibility between existing and future development resulting from the recommended land use changes. · raffic and Circulation - A new policy (ll,03) has been added which, along with an associated implementation measure, establishes mid-range of 'level of service aDw as a xtnimumlsvel of service for intersections and r~adway segments in Denyills, and establishes a traffic impact assessment and monitoring process. Policies in the General Plan call for balancing new development with adequate services and acceptable levels of service. 3) Natural Resources - Potential impacts on natural resources have been further mitigated by addition of policies intended to preserve and enhance stream channels and riparian corridors, and reduce orcontrol ~rading and earth movement in scenic and sensitive areas. WBl/F.t~, the Final BZR 1denttries trafflc and circulation tapacts as the only Impacts not being xLtlgated to an Insignificant level within the General Plan, xLtlgatlon measures recommended by the Draft w-ZR, or by policies ~hlch my be proposed by other agencies affecting the San Ramon Valley &tea. WHERFJ~, CEQA guideline section 15091 requires that findings be adopted vhlch tndlcate that changes or alterations have been required in or incorporated into the project which avoid or substantially lessen the significant environmental effects, or in the alternative that, in accordance with CEQA section 15093, if identified significant impacts are not at least substantially mitigated, the benefits of a proposed pro~ect shall be determined to outweigh the resulting unavoidable adverse environmental effects. NOW, THEREFORE, BE IT KESOLVEDthatthe Town Council hereby certifies that the Final EIR, including the draft Elm and Response to Comments attached hereto as Exhibit A, has bien completed in compliance with the California Environmental Quality Act of 1970, as amended; and BE IT ruKrn~ RESOLVED that the Town Council of the Town of Danvilla finds that significant impacts identifieS in the Final EIR for the General Plan have either been mitigated in the General Plan or that adequate measures have bean developed to mitigate impacts as indicated herein. The Town Council acknowledges however, the occurrence of significant effects which are not substantially mitigated in the area of traffic, and hereby adopts the following statement of overriding considerations: ~rw ff4 c Xntha area of traffic, the Town Council has revlsveS evidence that a lieteeS number of intersections are pro~ected to lyeted the acceptable level of service for peak period traffic established by the General Plan. Evidence Ant he record tndlcatesthatthespectftcchangesnscemsarYtommlntatnthe specified level of service would not in all cases be practical nor desirable from a safety or aesthetic perspective. The resulting width and complexity oft hose intermecttonsthatmay exceed the acceptable level of service would be undesirable, if the s~andardwere to besatntalned in these areas. 6 In addition, the potential impacts on regional traffic conditions, (particularly on 1-620) art ~varridan by the relatively small contribution of the land use changes recommended by the General Plan (resulting in less than a 1 ~ercent increase in volumes on 1-680) and need for balanced and economically sound growth in Danvilla.
