HomeMy WebLinkAbout4.5 TOWN OF Los ALTOS HILLS April 26, 1995 Staff Report to the Planning Commission RE: SITE DEVELOPMENT PERMIT FOR A NEW RESIDENCE AND POOL;LANDS OF WARD; 11881 FRANCEMONT DRIVE. FROM: Suzanne Davis, Planner SD RECOMMENDATION That the Planning Commission: Approve the requested Site Development Permit as submitted, subject to the attached conditions of approval. • BACKGROUND The subject property is parcel 3 of the Bellucci Subdivision (Francemont Estates). The lot is located on west side of Francemont Drive. The area closest to the street is relatively flat,while the rest of the land slopes up,with some areas exceeding 55%. The house and pool will be constructed on the lower part of the lot. There are a number of subdivision improvements which have not yet been completed. While the applicant can receive approval of the proposed projects (new residences and pools are also proposed on parcels 1 and 2),no building permits can be issued until the required improvements are completed to the satisfaction of the Town Engineering Department (see condition#17). DISCUSSION Site Data: Net Lot Area: 1.62 acres Average Slope: 20.9% Lot Unit Factor: 1.24 Floor Area and Development Area: Area Max. Prop. Exist. Incrs. Left Devel. 13,531 10,204 -0- 10,204 +3,327 . Floor 6,764 5,864 -0- 5,864 +900 The applicant is requestingapproval of a two-story residence and a swimming pool. The second story will cover just under 40% of the first floor. The second floor has been set back, and the architectural features include variations in elevations, roof planes and exterior building massing. Planning Commission April 26, 1995 Lands of Ward/parcel 3 Page 2 The size of the second story includes an additional 154 square feet which is counted because there is a first floor space which exceeds 17 feet (areas where the floor to ceiling height exceed 17 feet are counted twice). The maximum height of the house will be 26 feet as measured from the natural grade. Exterior materials will consist of stucco siding,wood windows and doors and tile roofing with four small skyligllts. A portion of the second story has built up membrane roofing. The proposed project will leave 900 square feet of MFA and over 3,300 square feet of development area for future additions or improvements. Three of the required parking spaces are provided in the attached three-car garage,with a fourth space adjacent to the garage. The garage has been staggered and the uncovered parking space has been offset from the garage so that the fourspaces are not in a single row. There is a portion of the driveway in the front setback near the entry to the proposed residence. This paving within the setback is not needed for turnaround or maneuvering of vehicles,but it will provide additional on-site parking. There are some Oaks on the site,but they are not within the proposed construction area. The Oaks and other existing trees will be maintained. There is a conceptual landscape plan included with the development plans to show proposed plantings for screening of the new residence and pool. The final landscape plan will be reviewed by the Site Development Committee once the house is framed. The Engineering Department has reviewed the plans and has recommended conditions of approval as specified in Attachment 1. This property also has some fill since part of the lot is within the 100 year flood plain. The elevations show the original grades prior to the fill being placed on the site, and the finished grade. Grading volumes for the project total 510 cubic yards (50 cu. yds. of cut and 460 cu. yids. of fill). The excess 410 cubic yards of fill will need to be imported tcYthe site. Some fill will be available from the excess cut on parcel 1, but it appears that it will be necessary to bring in additional fill to complete the grading. The Town Geologist has reviewed the plans and geotechnical reports and has visited the site. The Town Geologist has recommended approval of the project subject to conditions (see Attachment 3). The Fire Department had no recommendations. The Pathway Committee recommends that a type IIB path be constructed along Francemont Drive. This will be done as part of the subdivision improvements, so the condition of approval requires the applicant to rehabilitate the path as needed (see condition#16). Planning Commission April 26, 1995 Lands of Ward/parcel 3 Page 3 The project as proposed meets the requirements of the Zoning and Site Development Ordinances, and staff is recommending approval. Staff is available to answer any questions that the Commission or community may have. ATTACHMENTS: 1. Recommended conditions of approval 2.

TOWN OF LOS ALTOS HILLS 26379 Fremont Roadalca Los Altos Hills, California 94022 SUBJECT: Geologic and Geotechnical Review RE: Ward,Parcel 3- Adobe Creek Subdivision Francemont Drive File #205-94-ZP-SD-GD At your request, we have completed a geologic and geotechnical review of applications for proposed site residential development using: • S'oi1 Report prepared by Nielsen Geotechnical, dated November 16, 1994; • Site Development Plans (Sheets A1-A5, and C1) prepared by Woodson/Barksdale Architects and Giuliani & Kull, dated November 17, 1994; • - Report on the Consultation for the Adobe Creek Subdivision, prepared by Jo Crosby & Associates, dated February 2, 1993; • Engineering Geologic Investigation (report) for Parcels 1, 2 and 3 Francemont Estates, prepared by Louis A. Richardson, dated July 31, 1992; and • Geotechnical Engineering Evaluation (report)prepared by William McMorrow, dated August 20, 1992. In addition,we have reviewed pertinent technical documents from our office files (Adobe Creek Subdivision L1456 and Menlo Development L3313) and completed a recent site reconnaissance. DISCUSSION The applicant proposes to construct a single family residence and swimming pool in the central portion of Parcel 3 of the Adobe Creek Subdivision/Francemont Estates. The southern edge of the house is located immediately adjacent to the toe of a large Dormant Landslide. We previously reviewed a proposed development application for this parcel (review report dated July 7, 1993) and recommended that a formal groundwater monitoring and mitigation program be established prior to issuance of building or grading permits. ENGINEERING GEOLOGY • ENVIRONMENTAL EARTH SCIENCES • FOUNDATION ENGINEERING Suzanne Davis December 19, 1994 Page 2 L3304 Our Adobe Creek Subdivision review report dated March 12, 1993 addressed details of a recommended groundwater monitoring program, and future dewatering measures that may need to be implemented to ensure the stability of the Dormant Landslide. We recommended that a formal monitoring and mitigation program be established prior to issuance of grading or building permits on individual lots. We understand that_threegroundwater monitoring wells have been installed within the landslide. SITE CONDITIONS The subject property is generally characterized by gentle to very steep (1° to 35° inclination) northeast-facing hillside and valley floor topography. Approximately 3 to 5 feet of recently placed fill is present over most of the proposed building site. The referenced July 1992 report by Louis A. Richardson concluded that fill at the property came from several different sources,was highly variable in consistency,contained debris such as wood, concrete an old car parts, and should not be considered an engineered unit. The referenced November 1994 soil report by Nielsen Geotechnical concludes that the current fill on Parcels 1, 2 and 3 is well compacted based on the results of 9 exploratory borings. Wood or other debris was not encountered in these borings. It is our understanding, based on information provided by. John Nielsen (personal communication on December 12, 1994), that site fills have been reworked by large grading equipment since 1992. Site fill materials at the building site are underlain by deep unconsolidated alluvial deposits (gravel, sand silt and clay). The July 1992 report by Louis Richardson concluded that anticipated ground shaking could produce differential compaction of these underlying deposits. A portion of a large Dormant Landslide is located in the western half of the property. The western portion of the property is generally characterized by steep (i.e., 15° to 25° inclination),northeast-facing slopes. Past grading in this area has resulted in several unpaved access roadways and a somewhat level pad area in the southwestern corner of the property. Cut and fill slopes associated with the grading are inclined from 8° to 38°. Portions of the roadways direct runoff toward the proposed development. Drainage from the remaining portions of the property is characterized by uncontrolled sheet flow to the northeast. The potentially active trace of the Berrocal fault has been mapped approximately 400 feet northeast of the subject property. The referenced consultation report by Jo Crosby and Associates concludes that the Dormant Landslide has the potential for renewed movement and the stability of this feature is very sensitive to the level of groundwater. The consultant concludes that the site is safe for development (i.e., with respect to deep landsliding) if groundwater levels do not rise above the elevation of the lower building pad levels within the landslide mass. Current FEMA maps indicate that the building site is located within the limits of the 100-year flood along the nearby Adobe Creek. We have not received documentation to verify what extent of channel improvement or additional fill at the building pad (if any) may be required to address potential flooding hazards. William Cotton and Associates Suzanne Davis December 19, 1994 Page 3 L3304 CONCLUSIONS AND RECOMMENDED ACTIONS Proposed site development is constrained by potential landsliding, potential flooding, undocumented fill, expansive soils, anticipated strong to violent seismic shaking and the potential for seismically induced differential compaction of the underlying alluvial deposits. Based on our review of the latest project soil report by Nielsen Geotechnical, it appears that exiting fill conditions can be adequately addressed by current foundation recommendations. The potential impacts of seismically induced differential compaction should be specifically addressed by the current project geotechnical consultant. In addition, the consultant should evaluate any adverse impacts that abandoned access roads or steep graded areas, located upslope of the house site, may present to the proposed development. The adequacy of foundation design recommendations must be re-evaluated if any additional site fill is needed to mitigate flood conditions. _The applicant should be fully aware of the potential for cracking of asphalt and concrete paving at this site as stated on page 14 of the referenced soil report by Nielsen Geotechnical. Our current review does not include approval of specific geotechnical design for the swimming pool. Design criteria for the pool should be addressed after development of final site grading plans. Formal organization of a groundwater monitoring and mitigation program should be completed prior to issuance of building or grading permits. One of the two annual well inspections for the Dormant Landslide should be completed in the months of February or March when groundwater levels are likely to reach their high point. The existing three monitoring wells within the landslide should be equipped with locking caps and appropriate protective barriers to prevent accidental damage or vandalism to the well heads. The proposed development plan appears feasible with the implementation of appropriate engineering design measures. However,we recommend that the following items be satisfactorily addressed prior to issuance of permits for residential construction: 1. Supplemental Geotechnical Evaluations - It is important that the project geotechnical consultant (Nielson Geotechnical)be informed of any additional fill requirements at the house site that may result from required flood mitigation. After resolution of flooding issues, the consultant should review any modifications to the site grading plan and evaluate whether previously recommended foundation design criteria are still appropriate. The issues of potential seismically induced differential compaction, presented in the July 1992 report by Louis Richardson, should also be addressed. Estimates of total and differential settlement should be provided. The consultant should verify that proposed lot gradients and drainage design reflect the intent of recommendations by Jo Crosby and Associates (report of February 2, 1993) to reduce the infiltration of surface water. In addition, the consultant should evaluate any adverse impacts that abandoned access roads or steep graded slopes, located south and southwest of the house site, may present to the proposed development. Appropriate mitigation measures should be recommended if deemed necessary. William Cotton and Associates Suzanne Davis December 19, 1994 Page 4 L3304 The results of these supplemental evaluations should be submitted to the Town for review by the Town Geotechnical Consultant prior to issuance of building or grading permits. 2. Formal Organization of Monitoring Program-The groundwater monitoring program, descriptions of possible future mitigation measures, drainage easements and property assessments for the Dormant Landslide should be established to the satisfaction of the Town utilizing the concepts outlined by Jo Crosby and Associates. In addition, we recommend that one of the two annual well inspections be completed in the months of February or March when relatively high groundwater conditions may prevail. The monitoring program should be established prior to issuance of grading or building permits for development on individual lots. We suggest that the applicant install locking caps and protective barriers as soon as possible at the existing three wells to reduce the potential for damage. We recommend that the Town geotechnical Consultant be provided an opportunity to review specific requirements of the proposed monitoring program prior to implementation.

DISCUSSION The applicant proposes to construct a single family residence and swimming pool on each of the Parcels 1, 2 and 3 of the Adobe Creek Subdivision/Francemont Estates. We previously reviewed proposed development applications for these parcels (review reports dated December 19, 1994) and recommended that supplemental flood evaluations, geotechnical evaluations and formal establishment of a groundwater monitoring program be completed prior to issuance of grading or building permits on individual lots. We currently understand that the Santa Clara Valley Water District is not requiring additional improvements to the Adobe Creek channel to address potential flooding issues. The referenced consultation report by Jo Crosby and Associates concludes that the Dormant Landslide extending into the southern portions of the three parcels has the potential for renewed movement and the stability of thisfeature is very sensitive to the level of groundwater in the hillslope. The consultant concludes that the site is safe for development (i.e., with respect to deep landsliding) if groundwater levels do not rise above the lower building pad levels within the landslide mass. The consultant recommends that the three existing wells within the landslide be monitored on a regular basis and dewatering measures be implemented to control the groundwater if monitoring wells indicate rising water levels. CONCLUSIONS AND RECOMMENDED ACTIONS The request for supplemental geotechnical evaluations in our previous review has been satisfactorily addressed by the referenced report by Nielsen Geotechnical. However, formal organization of a groundwater monitoring and mitigation program should be completed prior to issuance of building or grading permits. As a minimum,we recommend thatannual well inspections for the Dormant_,Landslide be completed in the months.of January and March/April when groundwater levels are likely increasing or have reached their high point. A reading in January may point out the need for initiation of dewatering before critical levels are reached later in the rain season. The existing three monitoring wells within the landslide should be equipped with locking caps and appropriate protective barriers to prevent accidental damage or vandalism to the well heads. We recommend geotechnical approval of the subject applications for proposed construction on Parcels 1,2 and 3 with the following conditions: 1. Swimming Pool Design - Geotechnical design criteria for proposed swimming pools should be updated, as necessary, after the project geotechnical consultant has observed the drilling of foundation piers for proposed residences. Design criteria for pool shells should be re- evaluated if unanticipated adverse subsurface conditions are identified. William Cotton and Associates Susan Manca March 8, 1995 Page 3 The use of pressure-relief valves should be considered for all proposed swimming pools. A letter from the project geotechnical consultant addressing recommended pool design criteria should be submitted to the Town for appropriate technical review prior to issuance of building permits for pool construction. 2. Formal Organization of Monitoring Program - The groundwater monitoring program, descriptions of possible future mitigation measures, drainage easements and property assessments for the Dormant Landslide should be established to the satisfaction of the Town utilizing the concepts outlined by Jo Crosby and Associates. As a minimum, annual well inspections for the Dormant Landslide should be completed in the months of January and March/April. The monitoring program should be established prior to issuance of grading or building permits for development on individual lots. We suggest that the applicant install locking caps and protective barriers as soon as possible at the existing three wells to reduce the potential for damage. We recommend that the Town Geotechnical Consultant be provided an opportunity to review specific requirements of the proposed monitoring program prior to implementation. 3. Parcel 3 Drainage Improvements - As recommended by the project geotechnical consultant, the two narrow unpaved access roads directly south of Parcel 3 should be cleaned of forest debris and fine-graded so that these roads serve as interceptor benches that direct runoff to Francemont Drive (rather than onto Parcel 3). The consultant shall confirm that these measures have been adequately completed prior to final (as-built) approval of improvements on Parcel 3. 4. Geotechnical Plan Review - The applicant's geotechnical consultant shall review and approve all geotechnical aspects of the detailed building and grading plans (i.e., site preparation and grading, site drainage improvements and design parameters for foundations and driveway) to ensure that his recommendations have been properly incorporated. The results of the plan review should be summarized by the geotechnical consultant in a letter and submitted to the Town Engineer for review and approval prior to issuance of building permits for residential construction on individual parcels. 5. Geotechnical Field Inspection - The geotechnical consultant shall inspect, test (as needed), and approve all geotechnical aspects of the project construction. The inspections should include, but not necessarily be limited to: site preparation and grading, site surface and subsurface drainage improvements, and excavations for foundations and retaining walls prior to the placement of steel and concrete. The consultant shall inspect the drilling of a representative number of foundation piers on each lot and document the materials encountered. The final depths of all piers should be documented. This data should be included in the final as-built inspection report. • William Cotton and Associates Susan Manca March 8, 1995 Page 4 The results of these inspections and the as-built conditions of the project shall be described by the geotechnical consultant in a report and submitted to the Town Engineer for review prior to final (as-built) project approval.
