TO: FROM: GENERAL INFORMATION PROJECT: Subdivision Map application (Tentative Map 5588) for a 26 lot single family residential subdivision. APPLICANTS AND REPRESENTATIVES: Mike E. Milani James R. Stedman & Associates Civil Engineers 365 Lennon Lane #100 Walnut Creek, CA 94598 PROPERTY OWNERS: Pulte Home Corporation 4655 Old Ironside Drive, #320 Santa Clara, CA 95054 ASSESSOR PARCEL NUMBER: 941-115-14 PARCEL AND SURROUNDING LAND USES: The proposed residential project covers Parcel A of Parcel Map No. 2795 located in the southwestern corner of the City of Dublin. The 8.4+ acre site fronts on the south side of Betlen Drive and extends from its western terminus for 700~ feet. The site is bordered on the west by the Valley Christian Center complex, to the south by the slope easements and road right-of-ways for Dublin Boulevard and Interstate 580, on the north by existing single family residential development, and on the east by the partially developed eight-lot single family residential subdivision approved under Tract 4929. The Gross Residential Acreage (GRA) available for residential development is 9.1+ GRA (includes one half of the fronting right-of-way for Betlen Drive). PROPERTY DESCRIPTION, ZONING AND LAND USE: The existing elevation range of the site ranges from 555+ feet in the northeast corner of the site to 660+ feet in the northwest corner. Grading has previously occurred on the site as the southern half of the site has been previously utilized as a "borrow-pit". The site is currently vacant and is zoned R-1-B-E, Single Family Residential Combining District (10,000 square foot minimum lot size; 80 foot minimum average lot width). --------------------------------------------------------------------------- ITEM NO. 8 ~ COPIES TO: Applicant Owner File PA 86-058 ZONING HISTORY: The subject property was rezoned from A-2, Agricultural District, to the R-1-B-E, Single Family Residential-Combining District by Zoning Unit 5l0, approved by the Alameda County Board of Supervisors on November 27, 1986. On November 16, 1978, The California Conference of Methodist Churches received approval from the Alameda County Planning Commission for a two- parcel Minor Subdivision under Tentative Parcel Map 2795. The parcel split was requested in anticipation of the submittal of a Conditional Use Permit application for the development of a church on the 8.4+ acre subject property (Parcel A). The plans for development of a church on this site never materialized. Parcel B of the Minor Subdivision was subsequently split into eight single family residential lots under Tract 4929. APPLICABLE REGULATIONS: A. SUBDIVISION ORDINANCE Title 8, Chapter I, Alameda County Subdivision Ordinance as adopted and amended by the City of Dublin, reads in part: 8-1-2 INTENT. It is the intent of this chapter to promote the public health, safety and general welfare; to assure in the division of the land consistent with the policies of the Dublin General Plan and with the intent and provisions of the Dublin Zoning Ordinance; to coordinate lot design, street patterns, rights-of-way, utilities and public facilities with community and neighborhood plans; to insure the area dedicated for public purposes will be properly improved, initially, so as not to be a future burden upon the community; to reserve natural resources and prevent environmental damage; to maintain suitable standards to insure adequate, safe building sites; and to prevent hazard to life and property. B. GENERAL PLAN DESIGNATION AND POLICIES The site is designated by the City of Dublin General Plan as Residential: Single-family (0.9 to 6.0 units per Gross Residential Acre). General Plan Development Policies for the site are as follows: Site: Acres: Minimum-Maximum Units: General Plan Residential Designation: South side Betlen Drive, West of Prow Way 9 9-54 Single Family Residential Applicable General Plan Policies include the following: 2.l.3 Residential Compatibilty Guiding Policy A. Avoid abrupt transitions between single family development and higher density development on adjoining sites. Implementing Policy B. Require all site plans to respect the privacy and scale of residential development nearby. 3.3 OPEN SPACE FOR OUTDOOR RECREATION Guiding Policy E. Restrict structures on the hillsides that appear to project above major ridgelines. The present undisturbed natural ridgelines as seen from the primary planning area are an essential component of Dublin's appearance as a freestanding City ridged by open hills. -2- Implementing Policy F. Use subdivision design process and the site design review process to preserve or enhance the ridge lines that form the skyline as viewed from freeways (I-580, 1-680) or major arterial streets (Dublin Boulevard, Amador Valley Boulevard, San Ramon Road, Village Parkway, Dougherty Road). 5.6 SCENIC HIGHWAYS 1-580, 1-680, San Ramon Road and Dougherty Road were designated scenic routes by Alameda County in 1966. These are the routes from which the people traveling through Dublin gain their impression of the City, so it is important that the quality of views be protected. Guiding Policy A. Incorporate previously designated scenic routes in the General Plan and work to enhance a positive image of Dublin as seen by travelers. Implementing Policy B. Exercise design and review of all projects within 500 feet of a scenic route and visible from it. 7.2 EROSION AND SILTATION CONTROL Guiding Policies B. Regulate grading and development on steep slopes. Implementing Policies E. Review development proposals to insure site design that minimizes soil erosion and volume and velocity on slopes of over 30 percent. 8.0 SEISMIC SAFETY AND SAFETY ELEMENTS Implementation Policies 8.1.2 Required Geotechnical Analyses A. A preliminary geologic hazards report must be prepared for all subdivisions. Any other facility that could create a geologic hazard, such as a road or a building on hillside terrain, must also have such a study. Each of the hazards described in the Seismic Safety and Safety elements must be evaluated. This hazard analysis shall be prepared by a registered Engineering Geologist. F. Any changes in grading or building design that would be significantly affected by geologic hazards or soils conditions, or in turn would significantly alter geologic or soils conditions, shall be accompanied by a re-analysis of those conditions. In addition, any conditions discovered during excavation or grading that significantly depart from the previously described geologic and soils setting shall be evaluated. 9.0 NOISE ELEMENT Noise exposure contours projected for 2005 based on anticipated traffic volumes increases indicated noise in the 70 CNEL to 75 CNEL range at the south side of the property. -3- Guiding Policy A. Where feasible, mitigate traffic noise to levels indicated below: Land Use Compatibility for Community Noise Environments Land Use Category Normally Acceptable Conditionally Acceptable (Noise Insulation Features Required) Residential 60 CNEL 60-70 CNEL PREVIOUS APPLICATION SUBMITTAL: Planned Development (PD) Rezoning and Subdivision Map applications for a 44-10t single family residential development were previously submitted by Pulte Homes Corporation for this site. Those requests, City Files PA 86-010.1 and .2, were subject to three public hearings before the Planning Commission. The requests were ultimately withdrawn prior to any action being taken by the Planning Commission. The withdrawals were prompted by direction from the Commission that the 44-lot layout was inappropriate for the site, and that a project redesign reflecting the existing zoning requirements (e.i., 10,000 square foot minimum lot size, 80 foot minimum average lot width) and existing development constraints (topographic conditions present and access constraints) should be considered. ENVIRONMENTAL REVIEW: The City proposes to adopt a Mitigated Negative Declaration of Environmental Significance which finds the proposed project will not have a significant impact on the environment (see Exhibit A - Draft Resolution regarding the Mitigated Negative Declaration of Environmental Significance and Background Attachment 2 - Draft Mitigated Negative Declaration of Environmental Significance). NOTIFICATION: Public Notice of the July 21, 1986, hearing was published in The Herald, mailed to adjacent property owners, and posted in public buildings. ANALYSIS: The application by Pulte Homes Corporation proposes 26 single family residential lots on 8.4+ acres of the subject property is located at the top of Betlen Drive below the Valley Christian Center complex. The site is one of the few remaining unplanned and undeveloped residential properties in the City. Staff identified several primary issue areas during the review of the initial, 44-lot, development proposal filed over the subject property. The previously identified primary issue areas form an appropriate framework for review of the revised project submittal, and include the following: 1) General Plan Policies and Zoning 2) Site Layout and Dimensional Design Criteria 3) Traffic Circulation 4) Site Grading 5) Architecture and Landscape Architecture 6) Environmental Review 1. General Plan Policies and Zoning The reduced project density, at 26 lots, is within the density range established by the General Plan for the Residential Single-Family Land Use Category. The density of the project is consistent with the General Plan Implementing Policy that calls for an avoidance of abrupt density transitions between adjoining residential developments. -4- The proposed design of the cut-slope in the adjoining Valley Christian Center property appears to be inconsistent with the General Plan Implementing Policy that calls for use of subdivision designs which preserve or enhance the ridgelines that form the skyline for the City as viewed from the freeway or major arterial streets. Additionally, the proposal to grade pads out to the southerly limit of the property may make the future homes on these lots visible from the adjoining 1-580 corridor. Both these items should be addressed by minor project redesign and reflected through the Conditions of Approval for the project. The required adjustments to the project's preliminary grading plan should be such to minimize or eliminate the identified potential impacts (see Conditions #26, #27 and #29). 2. Site Plan Layout and Dimensional Design Criteria The proposed Gross Residential Density at 2.9 dwelling units/Gross Residential Acre has a density similar to existing residential projects. The typical minimum lot size and the typical minimum lot widths of lots in nearby residential projects are on summarized on Background Attachment #9. The use of wider minimum lot widths eliminates previously raised concerns regarding lot accessibility problems. The reduction in the number of proposed lots also eliminates the concern regarding on- street parking problems. The revised plans will provide at least two parking spaces for each lot in the subdivision. The available on- street parking will be fairly well-spaced across the project. A minimum area of 1,350 square feet of useable rearyard area was required to be supplied to the lots in the 88-10t Dolan School Site subdivision. This figure was derived from assigning a minimum of 15% of the average lot size in that subdivision (9,000~ sq. ft.) to be reserved for use as a level rearyard area. Within the Conditions of Approval of that subdivision, another requirement was imposed calling for a minimum level rear yard depth of 15 feet (with the bulk of the lots to provide 18 feet) measured from the rear of the unit to the nearest change in slope. While the concept of setting a minimum square footage standard for rearyard useable area is not derived from a zoning regulation, the concept warrants consideration to assure that each lot is provided a minimum, functional rear yard area. Staff recommends that the previously applied standard of 1,350 square feet (minimum) for the rearyard useable area be utilized for this project (see Condition #5 E). A review of the Applicant's revised subdivision layout reveals pad areas of an average size of 9,250+ sq. ft. (only two pads are proposed at less than 6,000 sq. ft. - Lots #3 at 5,400~ sq. ft. and Lot #4 at 5,800~ sq. ft.) 3. Traffic Circulation Within his memo of February 24, 1986, the City Engineer (see Background Attachment #8) recommended that a cul-de-sac be constructed at the intersection of Betlen Drive and proposed "A" street (generally situated at the current terminus of Betlen Drive). This design change would allow for the elimination of the non- functional right-of-way stub currently present at the terminus of Betlen Drive. The Conditions of Approval for this project should require the developer to initiate the necessary abandonment proceedings to provide for the City's consideration of abandoning the westernmost 85~feet of the right-of-way for Betlen Drive. The area, if abandoned, should be incorporated into the subject development proposal and should be utilized to allow a modified grading plan to be prepared for this portion of the project to provide for rounder slopes yielding smoother transitions into surrounding natural surrounding grades (see Condition #21). Development of the cul-de-sac at the end of Betlen Drive should be required to be done in a manner that provides for the development of a modified driveway connection to the DSRSD water tank. -5- 4. Proposed Site Grading Under the Applicant's proposed grading plan, the 8.4+ acre site would be extensively regraded to create a large interior pad (proposed pad elevations ranging from 607.0 to 623.0), and a total of six individual pads along Betlen Drive (proposed pad elevations ranging from 550.0 to 598.0) which generally match existing pad elevations of lots along the north side of Betlen Drive. The area proposed to accommodate the majority of the project grading is along the western edge of the property where the Applicant proposes to establish 2:1 cut slopes up to a height of 60+ feet. The majority of this proposed cut slope area would be located off-site on the adjoining Valley Christian Center property. The Church representatives have indicated their preliminary approval of the proposed grading concept in their letter of April 8, 1986 (see Background Attachment #7). As proposed, the southern end of the proposed 2:1 cut slope face would sit virtually at a 900 angle with the existing natural contours at the south-southeastern portion of the Church property. If graded as proposed, the cut-face slope could create a significant visual impact to viewers from the Valley floor and travelers along the 1-580 corridor. One area of substantive change to the grading plan from the original 44-lot submittal is the additional slope cuts proposed at the northwest corner of the site to accommodate the pad proposed for Lot #26. Even with the original 44-10t layout, the grading for this proposed area was not as severe as proposed by the new layout. If approved as submitted, the 2:1 cut slope area above proposed Lot #26 will extend 140+ feet above the proposed building pad, which will require up to 40 feet of cut to establish. When reviewed in relationship to the existing cut slopes adjoining to the north, the resultant slope area will have a chopped, unnatural, engineered appearance above the area "scooped out" to create Lot #26. Staff recommends the site grading plan be required to be adjusted to accommodate the following items: _ Adjust the grading design of the off-site cut slopes to provide use of contour-rounded grading designs which conform as closely as possible with surrounding natural slopes. The design of the cut slope area should be such to avoid a man-made, engineered appearance, and to allow the creation of a more gradual transitions back to the surrounding natural terrain (see Condition #26). In conjunction with this adjustment to the site grading, Staff recommends that Lot #26 be eliminated from the subdivision and that grading at the northwest corner of the project be adjusted to eliminate the "scooping-out" approach that would have been required to establish the pad for Lot #26 (see Condition #1). Place a portion of the slope area (5'+ in height, 10'+ in horizontal depth) at the rear of the lots along the west property line. This design modification would shift to the future property owners along the west property boundary the responsibility of ongoing maintenance for this portion of the slope and the drainage facility at the base of the slope. It would also allow the toe of this slope to be moved easterly to allow a slight reduction in the steepness and/or height of the cut slope (see Condition #27). _ Provide for the formation and recordation of a recorded slope mainentance easement between the Developer (to be ultimately shifted to the future property owners of lots at the western perimeters of the project) and the Church to clearly establish the respective on-going responsibilities for maintenance and up-keep of the proposed cut-slope and accompanying drainage facilities (see Condition #28). -6- _ Adjust the grading plan to provide for the development of a four- foot minimum height perimeter berm (with a six-foot high architectural-sound wall) along the south perimeter of the property to help soften the visual impact future development will create to views from traffic lanes of 1-580 (see Condition #29). 5. Architecture and Landscape Architecture With the previous plan (proposing 44 lots), Staff requested that the Applicant prepare and submit a Preliminary Landscape Plan to detail the proposed treatment of slope areas planned above and below the proposed development area. Planting of these areas was considered necessary to mitigate the visual impact of the height of the slopes and to soften the engineered appearance they will have. While the slope along Betlen Drive will be eliminated with the introduction of lots accessed from Betlen Drive, Staff still recommends use of landscaping on the slopes at the rear of those lots and on the slope at the west side of the project. The planting plan utilized for these areas should incorporate the use of 5 gallon sized trees to provide a balance between the desire to maximize the number of trees planted while also providing planting that will provide some level of planting mass within a three to four year time frame. Tree planting on the off-site cut slope area should be made a responsibility of the developer and should be done in conjunction with the development of a maintenance agreement requiring that the developer care for planting for a minimum of a two-year period to assure the majority of the tree planting can establish a foothold and will have a higher probability for long-term survival (see Condition #73). The size of the cut slope area above the project's west boundary is shown on the Applicant's submittal to cover approximately 1.2 acres. To meet the previously stated recommendations that these cut slopes be adjusted to provide smoother transition into existing slopes and to provide for the use of variable slopes, this cut slope area would apparently need to approximately double in size. A tree planting standard of one tree for each 2,000 ~ square feet of slope area is recommended and would require the planting of approximately 55 trees. A minimum ratio of one tree for each l,500 + square feet of slope area is recommended for the slope area above the lots fronting along Betlen Drive. This slope area proposed will be approximately 0.8 acres in size and would require approximately 24 trees (approximately 4 trees for each proposed lot to meet the recommended planting ratio). In addition to the above recommended slope planting ratios, Staff recommends that the developer be required to plant two trees in the front yard area of each lot created. Part of the review of the project's landscape architecture includes a review of the type and location of project fencing. The fence detail supplied by the Applicant for the original 44-lot layout was not considered by Staff to be substantial enough in either design or materials for use as low maintenance perimeter project fencing. An alternate design, which will require less long term maintenance and a more substantial appearance, should be submitted for review and approval by the City prior to the recordation of the Final Map for this project (see Condition #68). -7- 6. Environmental Review As indicated elsewhere in this Report, Staff is recommending that a Mitigated Negative Declaration of Environmental Significance be adopted for this project. The Initial Study prepared for this project identified the following five Environmental Components (see Background Attachment #2): 1. General Plan Policies and Zoning 2. Soils, Geology and Seismicity 3. Traffic Circulation 4. Noise 5. Visual Resources The Draft Mitigated Negative Declaration of Environmental Significance has been formatted in a manner that presupposes the Applicant will agree, through the course of the public hearing process, to project design changes and/or to enter into binding commitments that address and mitigate each potential significant environmental impact identified in the Initial Study prepared for this project. RECOMMENDATION FORMAT: 1) Hear Staff presentation. 2) Open public hearing. 3) Hear Applicant and public presentations. 4) Close public hearing. 5) Adopt Resolution regarding Mitigated Negative Declaration of Environmental Significance (Exhibit A). 6) Adopt Resolution regarding Tentative Map 5588 - PA 86-058 (Exhibit B) ATTACHMENTS: Exhibit A Draft Resolution regarding the Mitigated Negative Declaration of Environmental Significance Exhibit B - Draft Resolution regarding Tentative Map 5588 Exhibit C - Tentative Map Submittals Background Attachments: 1) Applicant's Written Statement and Environmental Assessment Form. 2) Draft Mitigated Negative Declaration of Environmental Significance and Letter calling for Applicant to provide project redesign or binding commitment that addresses and mitigates each potential environmental impact. 3) Site Location and Area Maps. 4) Applicant's Letter of April 10, 1986, regarding Off Site Water Line Easement Acquisition. 5) Peter Kaldveer and Associates, Inc.

Betlen Drive shall be terminated with a "knuckle" cul-de-sac of a design, location and side slope gradient determined acceptable to the City Engineer prior to recordation of the Final Map. Access to the DSRSD water tanks shall be provided for by the design of the new cul- de-sac. The Developer shall initiate the necessary abandonment proceedings to provide for the City's consideration of abandoning the westernmost 85+ feet off the right-of-way at the terminus of Betlen Drive. The area, if abandoned, shall be incorporated into the subject development (in part or in totality) to allow modifications of the project grading plan for this area to provide for rounder slopes yielding smoother transitions into natural surrounding grades. GRADING 26. Grading of the Valley Christian Center property shall be modified to provide rounded slopes of varying gradients to create a more natural appearance and to avoid a man-made appearance. As a general guideline, the Developer is advised that Staff's preliminary calculations indicate that the area involved with this cut slope may need to be increased from 1.18+ acres to approximately 2.25+ acres to meet the stated intent of this-Condition. The design of this graded slope area shall be subject to review and approval by the City Engineer prior to the recordation of the Final Map. 27. The drainage ditch to be constructed at the base of the proposed cut slope on the Valley Christian Center property and a 5'~ high - 10'~ deep portion of the proposed cut slope area shall be relocated to the interior of the rearyards of Lots #20 - #25. Maintenance of this ditch area shall be the responsibility of the respective property owners. The adjustment to the locations of the toe of the proposed cut slope shall be moved to allow a reduction in the steepness of the cut slope and/or the height of the cut slope. 28. Documentation shall be provided that a recorded agreement has been formulated between the Developer and the adjoining church property which establishes the respective ongoing responsibilities for the maintenance and upkeep of the proposed cut-slope and the accompanying drainage facilities serving that slope. 29. The grading plan shall be adjusted to provide for the use of a four foot minimum height, perimeter berm at the south property boundary which shall be provided in conjunction with the use of a six foot minimum height architectural-soundwall to aid the screening of the proposed development from view from the 1-580 traffic corridor. Prior to the recordation of the Final Map, the Developer shall document that the necessary design changes to Lots #16 - #21 have been made, in conjunction with the selection of unit type to be placed on the respective lots (as regards building footprint and building height), to assure that structures developed on these lots will not be visible from the adjoining 1-580 taffic corridor. 30. The Developer shall document that a diligent effort has been made to secure the necessary approvals to perform off-site grading to provide a smooth transition of slopes at the intersection of the rearyard slope of Lots 2 and 3 of Tract 4929 and the proposed Lots 11, 15 and l6 of the subject property. 31. Cut or fill slopes of a height greater than four feet, which are proposed to be established adjoining existing or proposed public right- of-ways, shall be redesigned to observe a flat and level area of a minimum depth of five feet as measured from the back edge of the sidewalk. That setback shall be increased as necessary for the corner areas of Lots #6 and #l2 to observe the City's Site-Distance Setback Requirements. 32. Prior to any grading of the site, a detailed plan covering grading (including phasing), drainage, water quality, erosion and sedimentation control for construction and the post-construction period shall be prepared by the project Civil Engineer and/or Engineering Geologist, and shall be submitted for review and approval by the City Engineer. Said plans shall include detailed design, location, and maintenance criteria of all erosion and sediment control measures. The plans shall attempt to assure that no increase in sediment or pollutants from the site will -5- occur. The plan shall provide for long-term maintenance of all permanent erosion and sediment control measures. Toes of fills and tops of banks shall be locates as required by the City Engineer. 33.

This report shall address the potential presence of springs on the site or on the adjoining portion of the Valley Christian Center property which will be impacted by this project. 34. Where soil or geologic conditions encountered in grading operations are different from that anticipated in the soil and geologic investigation report, or where such conditions warrant changes to the recommendations contained in the original soil investigation, a revised soil or geologic report shall be submitted for review by the City Engineer. It shall be accompanied by an engineering and geological opinion as to the safety of the site from hazards of land slippage, erosion, settlement and seismic activity. 35. Prior to commencement of construction of any structures, site grading shall conform with the recommendations of the project Soils Engineer, to the satisfaction of the City Engineer. A declaration by the Soils Engineer that he has supervised grading and that such conformance has occurred shall be submitted. 36. Prior to final preparation of the sub grade and placement of base materials, all underground utilities shall be installed and service connections stubbed out behind the sidewalk. Public utilities, Cable TV, sanitary sewers, and water lines shall be installed in a manner which will not disturb the street pavement, curb, gutter and sidewalk when future service connections or extensions are made. 37. Any grading on adjacent properties will require recorded written approval of those property owners affected. HANDICAPPED ACCESS 38. Handicapped ramps shall be provided as required by the State of California Title 24 and/or as determined necessary by the City Engineer. IMPROVEMENT PLANS, AGREEMENTS AND SECURITIES 39.

Our firm is currently performing geotechnical engineering services for the project and have completed the initial phase of our field investigation. Based on our review of the information gathered to date we anticipate that the cut slope will extend into sandstone bedrock materials. It is our opinion that a slope with an inclination of 2 horizontal to 1 vertical will be stable with respect to gross stability in these materials. Any slopes greater that 25 feet high should incorporate horizontal benches at intervals of no more than 25 feet vertically. The benches should be at least 10 wide and should have a two percent reverse slope gradient. The conclusions and recommendations presented in this letter are preliminary in nature and. have been made in accordance with generally accepted soil and foundation engineering principles and practices. If you have any questions concerning this letter, please contact us. Very truly yours, zz;f5?AND " Ronald L. Bajuniemi Vice President Engineer' INC.

The site occupies 10 acres in hilly terrain north of Interstate Highway 580 and south of Eet1en Drive. As shown on the Geologic Reconnaissance Map and Schematic Grading Plan, Plate 1, the site is situated on a topographic bench. Development will consist of 49 single-family homes. Cut slopes up to 30 feet high and fill slopes up to 60 feet high will be constructed to level and increase the size of the bench. Cut and fill slopes will be inclined at 2:1 (horizontal to vertical). A new roadway extending southward from Eetlen Drive will be constructed across the western portion of the property nezr the toe of a cut slope.

OJr scope of work was limited to a site reconnaissance and review of published literature regarding the property and vicinity per- formed by our engineering geologist. Subsurface exploration and labora- tory testing were not included. SITE ())I'[)ITIONS The site is located along the eastern slope of a ridge with gentle to moderately steep slopes. ElevatiorQ are in the range of 580 and 660 feet. Residential developnents surround the site on three sides, includ- ing the Valley Christian Center to the west. Cut slopes north of Dublin Road and Interstate Highway 580 border the site on the south. The small ravine in the central portion of the property was previously used as a borrow pit. Vegetation consists of dense grass and weeds with scattered trees and brush in the ravine within the central portion of the property. Bedrock exposed within the site consists of massive, occasionally to moderately fractured sandstone. Where exposed within the central ravine cut slopes, the sandstone is moderately weathered and contains inter- bedded siltstone and shale. Within other scattered exposures throughout the site, similar sandstone is exposed but is locally cemented, harder, and fossiliferous. Except where the sandstone is exposed, it is covered by expansive natural clayey soils. These soils commonly exhibit shrinkage cra~^s at the ground surface which result from changes in moisture content. HJmmocky areas probably resulting from downhill creep of expansive soils were noted in the areas indicated on Plate 1. However, no active landslides were observed. Fill deposits consisting of large sandstone boulders and loose soils are scattered along the north and west portions of the'site. A natural spring and other areas cfseasonal seepage were observed at the locations indicated on Plate 1. SEISMICITY The property lies within a tectonically active region in which numerous historical earthquakes have occurred. Major active faults in the region are capable of generating future earthquakes and strong shaking at the site. These include the Calaveras fault, 3/4-miles east, the Hayward fault, 7 miles southwest, and the San Andreas fault, approximately 24 miles southwest (Jennings, 1975). Other active faults exist in the region but generally lie more distant or have less potential for streng shaking at the site. /,,:, \: '~i/! 0.}; c ~'.;~. ,,,;~ September 17, 1985 17 ,579 ,001. 03 Pulte Home Corporation Mr. Don Filiatrault Page 3 Harding Lawson Assocl",tcu; Field observations and review of published geologic literature indicate there are no potentially active faults through or very close to the prop- erty (Hart, 1981). However, strong earthquakes on the active faults noted above possess the potential for seismically induced ground failure such as landsliding, surface cracking, and subsidence. CONCLUSIONS AND REa::t+1EI'DATIONS Based on our investigation, we conclude that the site is suitable for the proposed development from a geotechnical standpoint. Geologic hazards as well as soils and foundation problems are present; however, we believe that all are of a type that can be effectively mitigated by conventional geotechnical engineering 'techniques. ' Satisfactory slope performance can generally be provided by the use of relatively flat slopes, as planned, and through careful control of sur- face runoff and installation of subsurface drains in seepage areas. Where existing loose fills or soft soil zones are not removed by the grading, they should be removed and replaced with well-compacted fills where they could otherwise adversely affect the planned cut or fill slopes. Such corrective work should be performed in the soil creep zones to be filled, or elsewhere as indicated by the results of subsurface investigation. Satisfactory support for the light residential foundation loads can be achieved by the use of conventional shallow spread footings bottomed in firm soils or rock, or short drilled pier and grade beam foundations in expansive soil or fill areas. Foundation design should be based upon the results of a comprehensive geotechnical investigation including subsur- face investigation by test borings. All of the construction should be designed and constructed to resist strong earthquake shaking. When your plans are more advanced, we should review the site grading and building layout in order to formulate ~~e scope of further geotechnica:f investigation for design purposes. ,..,.-''':.......-'-:~7'..~..''"'.~ .v;. ..... -..
