At the August hearing, the Planning Commission recommended a version of the initial proposal which did not include residential units. This version of the project also reduces the floor area which brings the project into greater compatibility with adjacent development. | |||
The recommended proposal will conform to the existing front and rear yard, residential S-92 zoning setbacks. However, the placement of the elevator on the side of the building will create a 5-foot, 6-inch side yard on the east side, and the trellis will create a 5-foot, 1-inch setback on the west side. The building (with the exception of the elevator and trellises) is proposed to be 13 feet from the eastern property line and 10 feet from the western property line. The setbacks experienced at the ground level are comparable to commercial districts. | |||
Within commercial districts which do not abut residential development, “zero yard” setbacks are allowed, and typically a 5-foot setback is required when residential abuts commercial. PUD zoning allows site-specific setbacks; however, the proposed setbacks are similar to most commercial zoning in the County. | |||
3. |
Operational/Quality of Life Issues | ||
The approval of additional commercial development in this area was of concern to the residents in the adjacent high-density multi-family buildings. If the subject property was developed at the density allowed on adjacent properties to the east, up to 23 units could be built; however, there is a community consensus not to allow more high-density residential development on the site. | |||
The applicant held several meetings with homeowners associations and interested parties to hear and address concerns. In response to concerns raised by the public, the Planning Commission, and County departments, the following modifications and conditions were included. | |||
To reduce privacy and/or noise concerns for residents on adjacent parcels: (1) access to the second floor roof has been limited for maintenance purposes only; (2) landscaping has been clarified to include a redwood tree hedge to be planted between the subject site and White Oak, and tall trees to be planted in the rear of the property as screening for Menlo Commons; and (3) the residential component was removed from the project. | |||
To address other quality of life concerns, the Planning Commission added these conditions: (1) medical and dental offices are expressly prohibited; and (2) the automatic shade/blind system was required to be timed with sunrise and sunset on a year-round basis. In addition, the applicant is providing access to the new fire hydrant to the White Oak complex, which does not have water sprinklers. | |||
4. |
Findings | ||
Approval of the PUD proposal requires that findings be made regarding the proposed General Plan Land Use Map Amendment, the Planned Unit Development District Rezoning and Grading Permit. These findings are discussed in the “Key Issues” in Section A of the August 26, 2009 Planning Commission report, and summarized here. | |||
To enact a PUD District, the Planning Commission shall have “reviewed a precise plan of the subject area and its environs, and found that the proposed zoning of the area would be in harmony with said plan, and would not be in conflict with the County Master Plan [i.e., 1986 General Plan], or with any current land use plan for a sub-area of the County previously adopted by the Commission.” The Planning Commission has reviewed the subject area including zoning for the adjacent community and found that it is harmonious and not in conflict with the General Plan or other land use plans. | |||
The necessary findings to allow the requested PUD District are as follows. | |||
a. |
Is a desirable guide for future growth of the subject area of the County. | ||
The professional office building is a compatible use which will not replicate or compound land use impacts associated with high-density residential uses. Based on existing conditions, construction features, conditions of approval, and the nature and scope of the proposed commercial use, the project will not significantly intensify the existing impacts from high-density residential, with respect to traffic patterns accessing Sand Hill Road, and the increased noise levels. | |||
In addition, since the project is designed to attain LEED certification status, the project is developed with a high level of attention to the environmental impact that would be created by construction, as well as, the ongoing use and maintenance of the building. | |||
b. |
Will not be detrimental to the character and social and economic stability of the subject area and its environs, and will assure the orderly and beneficial development of such areas. | ||
As previously discussed, the project has been designed to reduce impacts to the surrounding properties. Anticipated impacts have been mitigated and conditioned in a way to ensure there is no detrimental change in the social character of the area. The proposed office will not involve manufacturing, retail sales, distribution, or medical offices; the size of the employee base has been limited and activity outside of the building on the site has been limited. Design features such as automatic shades, vegetative buffer screens, and placement of equipment underground greatly reduce impacts. In addition, there is an economic benefit to the area since the office employees will utilize surrounding retail businesses. This combination of activity makes the proposed PUD compatible with surrounding developments. | |||
c. |
Will be in harmony with the zoning in the adjoining unincorporated area. | ||
The surrounding zoning is PUD for a professional office complex use in the unincorporated area, and high-density residential in the incorporated areas of the City of Menlo Park. Both types of zoning are compatible with the proposed use. The recommended project will involve use(s) which will have non-significant environmental impacts when mitigated, such as noise and traffic. Environmental impacts from the site on surrounding uses have been evaluated and with design features and limitations on the use, the intent of the proposed project is to create a harmonic situation. | |||
d. |
Will obviate the menace to the public safety resulting from land uses proposed adjacent to highways in the County, and will not cause undue interference with existing or prospective traffic movements on said highways. | ||
The project site is not adjacent to any County highway; however, it is adjacent to a major arterial road. As discussed in the revised Mitigated Negative Declaration, the applicant conducted a traffic study, and driveway design study to evaluate the impact of the project on Sand Hill Road. | |||
The reports were reviewed by the Department of Public Works and it was determined that there would not be a significant impact to the Level-of-Service on the road created by the proposed development. In addition, the project’s ingress and egress locations were evaluated to ensure that there is adequate pedestrian and bicycle safety, as well as line-of-sight clearance and space between driveways on adjacent properties. | |||
To ensure adequate transportation safety, several features have been incorporated. These changes range from driveway redesign, signage, a loading zone, and vehicle egress warning system. Review of the proposed plans indicates standards for safety for vehicles, pedestrians and cyclists have been met by this proposal. The City of Menlo Park reviewed the project and the recommendations from Menlo Park and Public Works Department were incorporated into the project. | |||
e. |
Will provide adequate light, air, privacy and convenience of access to the subject property and further, that said property shall not be made subject to unusual or undue risk from fire, inundation, or other dangers. | ||
The proposed design features a building constructed primarily from glass and wood. Therefore, the offices will have adequate light. There is a small park/green space proposed to the rear of the building. | |||
No access concerns were raised in the traffic study or raised by the reviewing agencies. There are no mapped dangers, and the review and conditioning of the project by Menlo Park Fire and San Mateo County Building Section manage typical risks from dangers such as fire. | |||
f. |
Will not result in overcrowding of the land or undue congestion of population. | ||
The surrounding, high-density residential buildings complement the commercial/office use in that traffic and noise generation patterns will not occur at the same times and compound issues for residents. No residential uses are proposed on the site. In addition, the office presents an opportunity for there to be a “life/work” balance for nearby residents. | |||
With respect to compliance with the Grading Ordinance, the mitigations which are necessary to prevent any significant impact from the proposed grading are discussed in detail in the Mitigated Negative Declaration. All of the findings can be made since the applicant agrees to comply with the Grading Ordinance and conditions from the Geotechnical Section. | |||
B. |
ENVIRONMENTAL REVIEW | ||
An Initial Study was completed and a Mitigated Negative Declaration was issued and circulated for this project according to the California Environmental Quality Act (CEQA) requirements, with a review period from January 12, 2009 through February 4, 2009. A revised Mitigated Negative Declaration with a circulation review period of July 3 through July 23, 2009 was prepared to more thoroughly address pedestrian and bicycle safety and noise. New mitigation measures were added to ensure adequate pedestrian and bicycle safety. No additional comments were received during the comment period. | |||

PLANNING AND BUILDING DEPARTMENT | ||||
RECOMMENDED FINDINGS AND CONDITIONS OF APPROVAL | ||||
Permit File Number: PLN 2008-00136 |
Board Meeting Date: October 6, 2009 | |||
Prepared By: Erica Adams, Project Planner |
For Adoption By: Board of Supervisors | |||
RECOMMENDED FINDINGS | ||||
The Planning Commission recommends to the Board of Supervisors that they: | ||||
Regarding the Environmental Review, Find: | ||||
1. |
That the Mitigated Negative Declaration is complete, correct and adequate and prepared in accordance with the California Environmental Quality Act and applicable State and County guidelines. The public review period for this document was July 3, 2009 to July 23, 2009. | |||
2. |
That, on the basis of the Initial Study, comments received hereto, and testimony presented and considered at the public hearing, there is no substantial evidence that the project, if subject to the mitigation measures contained in the Mitigated Negative Declaration, will have a significant effect on the environment. For impacts identified in the Initial Study/Negative Declaration as “significant unless mitigated,” staff has proposed mitigation measures which, when implemented, ensure that impacts are not significant. The Initial Study/Negative Declaration does not identify any significant or cumulative impacts associated with this project. | |||
3. |
That the Mitigated Negative Declaration reflects the independent judgment of San Mateo County. The Mitigated Negative Declaration was prepared by the project planner. | |||
4. |
That the mitigation measures identified in the Mitigated Negative Declaration, agreed to by the applicant, placed as conditions on the project, and identified as part of this public hearing, have been incorporated into the Mitigation Monitoring and Reporting Plan in conformance with California Public Resources Code Section 21081.6. Proposed mitigation measures are included as Conditions 1, and 15 through 37 in the recommended conditions of approval in this attachment. | |||
Regarding the General Plan Land Use Map Amendment, Find: | ||||
5. |
That the General Plan Land Use Map amendment is compatible with, will create a harmonious arrangement of land uses with, and will not be in conflict with the General Plan as discussed in Section A.1 of this staff report; and | |||
6. |
Adopt a resolution amending the County General Plan Land Use Map to change the subject parcels’ General Plan Map designation from “Medium-Low Density Residential” to “Office Commercial.” | |||
Regarding the Planned Unit Development District Rezoning, Find: | ||||
7. |
That the proposed zoning of the area would be in harmony with the submitted plan of the subject area and its environs, and would not be in conflict with the County Master Plan [i.e., 1986 General Plan], or with any current land use plan for a sub-area of the County previously adopted by the Board of Supervisors, and that the specific PUD District under consideration: | |||
a. |
Is a desirable guide for future growth of the subject area of the County. | |||
b. |
Will not be detrimental to the character and social and economic stability of the subject area and its environs, and will assure the orderly and beneficial development of such areas. | |||
c. |
Will be in harmony with the zoning in the adjoining unincorporated area. | |||
d. |
Will obviate the menace to the public safety resulting from land uses proposed adjacent to highways in the County, and will not cause undue interference with existing or prospective traffic movements on said highways. | |||
e. |
Will provide adequate light, air, privacy and convenience of access to the subject property and further, that said property shall not be made subject to unusual or undue risk from fire, inundation, or other dangers. | |||
f. |
Will not result in overcrowding of the land or undue congestion of population. | |||
PUD-134 will allow for professional/commercial/administrative office uses, which are similar to other uses found in the vicinity, and have been historically compatible with each other. The intensity of the commercial use has been limited to ensure that it is appropriate for this site and does not negatively impact the adjacent high-density residential uses. | ||||
In respect to the allowed uses, and with respect to the specific design of the PUD, the proposed zoning is compatible with both County zoning districts and zoning districts located in the City of Menlo Park. | ||||
Environmental studies were conducted to ensure that there will not be any threat to public safety. The project has been reviewed and evaluated by the Menlo Park Fire Department. In addition, light and shadow studies have been conducted to maximize light, air, privacy and convenience; and | ||||
8. |
Adopt the ordinance to change the subject parcel’s Zoning Map designation from R-1/S-92 (Single-Family Residential/10,000 sq. ft. Minimum Parcel Size) to “PUD-134” (Planned Unit Development-134); and | |||
9. |
Adopt the ordinance to enact the “PUD-134” (Planned Unit Development-134) Regulations, applicable only to the subject parcels. | |||
Regarding the Grading Permit, Find: | ||||
10. |
That the granting of the permit will not have a significant adverse effect on the environment due to the fact that the proposed grading will be subject to conditions of approval that include pre-construction, during, and post-construction measures to ensure that the project is in compliance with San Mateo County Grading Ordinance. | |||
11. |
That the project conforms to the criteria of Chapter 8, Division VII of the County Grading Ordinance, including the standards referenced in Section 8605 thereof. | |||
These standards are addressed through the erosion and sediment control measures that have been required, must remain in place, and will be monitored throughout construction. A dust control plan must be submitted for approval by the Department of Public Works and implemented on the site. The proposed grading plan has been prepared by a licensed civil engineer and reviewed by the San Mateo County Department of Public Works and grading is only allowed during the period between April 15 and October 15. In addition, the project is required to obtain a National Pollutant Discharge Elimination System (NPDES) Permit. | ||||
12. |
That the project is consistent with the General Plan with respect to grading allowed on land designated as “Office Commercial.” | |||
RECOMMENDED CONDITIONS OF APPROVAL | ||||

Ambient decibel levels for the project shall not exceed those of the City of Menlo Park’s Noise Ordinance. | |||
35. |
All project structures shall meet the requirements and recommendations of the California Building Standards Code and local amendments, Structural Engineers Association of California, the County Geologist, and the soil and foundation investigation report submitted for the project site. Assumptions and design parameters are subject to approval by the County Geologist. | |||
36. |
If, during the construction phase, any archaeological evidence is uncovered or encountered, all excavations on the site within 30 feet shall be halted, and the applicant shall retain an archaeologist to investigate the findings as well as informing the County. In addition, the Current Planning Section shall be notified of such findings and no additional work shall be done on-site until the archaeologist | |||
has recommended appropriate measures and those measures have been approved by the Current Planning Section. | ||||
37. |
No site disturbance shall occur, including any grading or tree removal, until a grading permit and building permit have been issued concurrently. | |||
38. |
Upon completion of the excavation for the below ground parking structure/building footprint, Paragon Geotechnical, Inc. (or another reasonably acceptable, qualified geotechnical engineer), shall observe the exposed sub-grade prior to construction of foundations/slab-on-grade to verify that the structure will be founded in the bearing material anticipated. | |||
39. |
Groundwater control (i.e., watering, water-tight shoring) will be required for excavation extending into the groundwater table. | |||
40. |
Below ground structures shall be waterproofed as appropriate. Waterproofing shall be designed by the project architect or structural engineer. | |||
41. |

43. |
Prior to the beginning of any construction activities, the applicant shall submit to the Planning Department for review and approval an erosion and drainage control plan, which shows how the transport and discharge of soil and pollutants shall be minimized. The plan shall be designed to minimize potential sources of sediment, control the amount of runoff and its ability to carry sediment by diverting incoming flows and impeding internally generated flows, and retain sediment that is picked up on the project site through the use of sediment-capturing devices. The plan shall also limit application, generation, and migration of toxic substances, ensure the proper storage and disposal of toxic materials, and apply nutrients at rates necessary to establish and maintain vegetation without causing significant nutrient runoff to surface waters. Said plan shall adhere to the San Mateo Countywide Stormwater Pollution Prevention Program “General Construction and Site Supervision Guidelines,” including: | |||
a. |
Sequence construction to install sediment-capturing devices first, followed by runoff control measures and runoff conveyances. No construction activities shall begin until after all proposed measures are in place. | |||
b. |
Minimize the area of bare soil exposed at one time (phased grading). | |||
c. |
Clear only areas essential for construction. | |||
d. |
Within five days of clearing or inactivity in construction, stabilize bare soils through either non-vegetative BMPs such as mulching, or vegetative erosion control methods such as seeding. Vegetative erosion control shall be established within two weeks of seeding/planting. | |||
e. |
Construction entrances shall be stabilized immediately after grading and frequently maintained to prevent erosion and control dust. | |||
f. |
