(a)

Site development plan. A site development plan has been prepared and approved by the advisory agency in accord with Section 14-25.100 of the Subdivision Ordinance, and the physical location of each use and structure is as set forth on such approved plan. In addition to the regulations set forth in Section 14-25.100, the site development plan shall incorporate the following design objectives:

(1)

All roads, buildings and other structural improvements or land coverage shall be located, sited and designed to fit the natural topography and shall minimize grading and modification of existing land forms and natural characteristics.

(2)

The planting and landscaping portion of said plan shall, insofar as is reasonably practical, provide for the retention of existing vegetation and shall include an erosion and sediment control element setting forth reasonable mitigation measures in accord with the excavating and grading and subdivision regulations of the City.

(3)

Grading shall be representative of adjacent topography and be an extension of natural contours insofar as reasonably practical, and shall be designed to avoid or fully mitigate potential erosion, flooding, geotechnical and other hazards.

(4)

Water, sewer and other utility services, streets and other access routes shall be designed to avoid any geologic or soils hazard and shall be specifically engineered to prevent the risk of failure or collapse. Setbacks from hazard areas shall be in accord with the engineering geologic and geotechnical engineering investigation report and recommendations.

(b)

Engineering Geologic and Geotechnical Engineering reports. A preliminary engineering geologic and geotechnical engineering investigation(s) and report(s) prepared by a certified engineering geologist licensed by the State and by a registered geotechnical engineer or civil engineer qualified in soils mechanics licensed by the State, shall be filed in conjunction with the site development plan unless the City Engineer and Geotechnical Consultant determine that existing information pertinent to the subdivision or site approval makes preliminary analysis or any part thereof unnecessary. The geologic and geotechnical reports shall fully and clearly include:

(1)

A description and discussion of engineering geologic conditions at the site, including natural and artificial earth materials, structural lineations or discontinuities, surface and ground water conditions, and all other pertinent conditions or characteristics of the site, with reference to surface conditions and exposures, geomorphology, and graphical logs of subsurface excavations.

(2)

An engineering geologic map of the site on a suitable topographic base, showing, as a minimum: the distributions of geologic materials on the site based upon mapping of geomorphic conditions and geologic exposures on and around the site; geologic features and potential hazards; and the locations of all existing and intended improvements on the site.

(3)

An evaluation of all geologic hazards and geotechnical constraints that affect, or potentially could affect, the site relative to the existing or intended land use. This should include a clear statement as to whether a hazard exists at the site which may lead to structural damage if not corrected, an evaluation of the risk(s) each hazard poses, and the basis or reasoning for assigning specific risks.

(4)

A geotechnical (soil and foundation) engineering investigation addressing properties of earth materials, site preparation (clearing and stripping), grading requirements (cut and fill design and construction), pavement design, drainage (surface and subsurface), utility trench backfilling, design parameters for foundations, retaining walls and swimming pools, slope stability, technical plan review, and field inspection procedures.

(5)

Recommendations for appropriate grading procedures, geotechnical design criteria and any corrective measures deemed necessary to prevent or significantly mitigate potential damage to the proposed project and to eliminate potential damage to adjacent properties and to otherwise insure safe development of the property.

(6)

Recommendations for additional investigations that should be made to insure safe development of the property.

(c)

Application acceptance. An application shall not be deemed complete until the City Engineer grants geotechnical clearance.

(d)

Additional studies required. The City shall also require the following additional studies prior to approval of a site development plan or as deemed necessary by the City Engineer, unless the City Engineer and the City Geotechnical Consultant determines that existing information pertinent to the subdivision or the site approval provides the same data as would have been obtained from any or all of such additional studies:

(1)

With respect to any terrain that may be susceptible to impacts from existing or potential instability, an investigation by a certified engineering geologist shall be required for all slopes affecting future or existing development. This investigation shall include a detailed evaluation of the natural slope conditions and recommendations for the treatment or correction of any potentially unstable slopes. Slope stability studies may require extensive subsurface exploration and analysis.

(2)

A slope stability analysis showing the proposed building footprint(s) and immediately surrounding areas having an adequate factor of safety of at least 1.5 under static conditions against failure in the event of the maximum expected earthquake on recognized faults, including but not necessarily limited to the San Andreas, the Berrocal, the Monta Vista/Shannon or the Sargent faults.

(3)

With respect to any area in the State's Special Studies zones or within two hundred feet of a mapped or otherwise recognized trace of a potentially active earthquake fault, an investigation by a certified engineering geologist addressing the seismic hazards related to the nearby trace, with particular emphasis on evaluation of possible surface faulting and characterization of seismic ground motion. Investigative techniques may require geologic and geomorphic mapping and analysis, subsurface exploration, and possibly geophysical traverses to demonstrate that no fault exists within fifty feet of a structure for human habitation. If deemed necessary by the City Geotechnical Consultant, an area greater than two hundred feet from a possible fault trace may be subject to the same investigative requirements and an increased setback of structures for human habitation from faults, may be required.

(e)

Inspection reports. The results and recommendations of the engineering geologic and geotechnical engineering investigations referred to in subsections (b) and (d) of this Section shall be reviewed and approved by the City Engineer and the City Geotechnical consultant and shall become conditions of approval of a development proposal. The Geotechnical Engineer and the Engineering Geologist may be required to submit reports during grading, during construction, and following completion of the project. The final report(s) shall affirm that the grading and foundation excavations were done under the supervision of an appropriate registered Geotechnical Engineer and/or Engineering Geologist, shall describe the as-built conditions of the project, and shall contain such other information as may be required by the City Engineer and City Geotechnical Consultant.

(f)

Financial assurances. The applicant shall post security deposit or a bond of an amount determined by the City Engineer as one measure to ensure the completion of all geological and geotechnical reports and corrective work required as part of conditions of the project approval.

(g)

Location of building sites.

(1)

In locating building sites, preference shall be given to areas classified in the City's Ground Movement Potential Maps as Sbr, Sls, and Sun. Sites on potentially moving slopes (Pmw, Ps, Pd, Paf and Pdf), sites within the areas with fault rupture potential (Pf) and sites on moving slopes (Ms) shall not be approved unless geologic and soil engineering analysis provided by the applicant demonstrate long-term stability to the satisfaction of the City Engineer and the City Geotechnical Consultant. No tentative or final map, building site approval or building or grading permit shall be granted for a property which includes land within an Md area unless it complies with all the requirements described in Section 16-65.030. No building or grading permit shall be issued for construction of any new building or structure, or addition to any existing building in any (Pf) area unless it complies with all requirements described in Section 16-65.050.

(2)

Corrective measures which are deemed necessary by the City Engineer and Geotechnical Consultant shall be reviewed and approved by the Planning Commission subject to the following findings: That the measures necessary to permit such development are (i) consistent with the objectives of this zone district as set forth in Section 15-20.010; (ii) necessary to minimize risks from geologic hazards; (iii) will not result in the removal of any protected tree, as described in Section 15-50.050; (iv) will not result in irrevocable damage to the City's scenic resources; and (v) will produce a benefit to the general public greater than the environmental impact of the corrective measures.

(3)

The City may require an additional fee from the applicant to cover the expense of producing ground movement potential maps of the geological study area in which the property is located, including areas that may suffer potential ground movement as a result of the proposed development.

(4)

The average natural grade of the footprint underneath any dwelling unit or other structure shall not exceed thirty percent slope, except that a variance pursuant to Article 15-70 of this Chapter may be granted.

(1)

Grading shall be limited to the minimum necessary for use of a site. Portions of a site exceeding thirty percent slope shall not be graded without prior specific approval by the Planning Commission. Grading shall be minimized in areas classified in the City's Ground Movement Potential Maps as Ps or Pd. Any grading which would unreasonably affect the natural topography of the area shall not be permitted.

(2)

The combined cut and fill of any grading on a hillside lot shall not exceed 1,000 cubic yards, including any excavation for a swimming pool, unless a larger quantity is approved by the Planning Commission based on the finding that:

(a)

The additional grading is necessary in order to allow reasonable development of the property or to achieve a reasonable vehicular access to the proposed development.

(b)

The natural land forms and vegetation are being protected.

(c)

The increased grading is necessary to promote the compatibility of the construction with the natural terrain.

(d)

The increased grading is necessary to facilitate an architectural design which is integrated into the natural topography.

(e)

The increased grading is necessary to reduce the prominence of the construction as viewed from surrounding views or from distant community views.

(3)

Corrective grading for existing or proposed developments may be permitted with prior specific approval by the Planning Commission based upon findings that the corrective grading: (i) is consistent with the objectives of this zone district as set forth in Section 15-20.010; (ii) is necessary to minimize risks from geologic hazards; and (iii) will not result in irrevocable damage to the City's scenic resources; and (iv) will produce a benefit to the general public greater than the environmental impact of the corrective grading; and (v) will not result in the removal of any of protected tree, as described in Section 15-50.050.

(4)

Grading and other site improvements under and around structures shall be designed to minimize visual impact as viewed from other properties.

(5)

Cut or fill slopes shall not exceed three horizontal to one vertical.

(i)

Any private street or driveway which exceeds a grade of eighteen percent for a distance in excess of fifty feet, shall also require approval by the Planning Commission upon all of the following findings that the: (i) construction of the driveway will prevent damage from geologic hazard, (ii) will minimize grading and visual impact and (iii) will result in preservation of natural vegetation and prevent destruction of wildlife habitat.

(j)

Landscaping. In the selection of new landscaping, preference shall be given to natural, indigenous and drought resistant plants and materials in accordance with City Xeriscape Standards. Nonindigenous landscaping shall be limited to the immediate area around the house. The total of non-native landscaped area including the allowable impervious coverage shall not exceed twelve thousand square feet. The impervious coverage shall be determined subject to limitations set forth in Section 15-20.080 of this Article. The remaining portion of the site shall be preserved in a natural and undisturbed state except for necessary clearing for the purpose of prevention of fire hazard as required by the City Code Article 7-15. Removal of existing native trees shall be subject to the regulations provided in Article 15-50 of the City Code and shall be replaced by same or similar species as required by the City Arborist.

(k)

Open space dedications. At least thirty percent of the gross site area of a subdivision, of a new home or of an addition, or combination of successive additions over the life of the structure, resulting in an increase of 50% or greater to the floor area of an existing home, shall be dedicated in fee to the City of Saratoga at the time of recordation of the final map or building permit whichever comes first. The location of said open space shall be subject to the review and the approval of the Planning Commission. A written agreement describing the open space area shall be executed between the property owner and the City and recorded in the office of the County Recorder. Such agreement shall set forth the restrictions and allowable uses for the open space area, as determined by the Planning Commission. The allowable uses shall be consistent with and promote the purposes of Section 15-20.010 of the City Code.

The reduction in the lot size is for the purpose of clustering building sites in order to create dedicated publicly owned open space which may contain recreation facilities, including but not limited to, equestrian and hiking trails, as permitted in Section 15-20.020(h).

(2)

The reduction in lot size is offset by an equal or greater area of land which is dedicated to the public as permanent open space.

(3)

The cluster development reduces the gross development area which shall include but not be limited to grading, streets, driveways, main structures, accessory structures and impervious coverage so as to minimize, to the extent possible, views of such area from public lands, streets and highways.

(4)

No single lot has a net site area of less than twenty thousand square feet.

(5)

The total number of lots into which the property is being subdivided shall be determined in accordance with the following formula:

a = 1 / 0.0609375 - 0.00109375 S

Where:  a is the average land area per dwelling unit
S is the average slope of the lot in percent.

The average slope of a lot or parcel shall be determined according to the following formula:

S = 0.00229 x IL / A

Where:  S is the average slope of the lot in percentage
I is the contour interval in feet
L is the combined length of contour lines in feet
A is the gross area of the parcel in acres.

(6)

The size of each unit shall be determined in relation to the size of the lot on which it is located and the average slope of the site, in accordance with the formula set forth in the Design Review Ordinance Section 15-45.030. In no case shall a single unit exceed six thousand square feet in area.

(7)

The clustering of building sites will result in greater preservation of the natural terrain and vegetation.

(8)

The use permit approved by the Planning Commission includes specified standards which may deviate from those contained in this Article as follows: (i) length of driveway, (ii) reduction in building height, (iii) reduction in allowable floor area, (iv) reduction in site coverage, (v) increase in site dimensions, and (vi) increase in setbacks.
