Conformance with the Grading Ordinance | ||||||
The Community Development Director made the required findings associated with the grading permit based on the following: | |||||||
The proposed grading plan was prepared by a licensed civil engineer and reviewed by the San Mateo County Department of Public Works. The grading plan is based on two independent, but concurring geotechnical studies and has been reviewed by the Department of Public Works. The project conforms to the criteria of Chapter 8, Division VII of the Grading Ordinance, including the standards referenced in Section 8605. Finally, the proposed grading will be subject to standard 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. | |||||||

ENVIRONMENTAL REVIEW | ||||||
The project is categorically exempt from CEQA pursuant to Section 15303, Class 3(a), construction of a single-family residence, in a residential zone, within an urbanized area. | |||||||

Board Meeting Date: October 20, 2009 | ||||||
Prepared By: Erica D. Adams |
For Adoption By: Board of Supervisors | ||||||
RECOMMENDED FINDINGS | |||||||
For the Environmental Review Find: | |||||||
1. |
That the project is exempt from environmental review pursuant to the California Environmental Quality Act (CEQA), Section 15303, Class 3, relating to the construction of a single-family residence, in a residential zone, within an urbanized area. | ||||||
For the Design Review Find: | |||||||
2. |
That the project has been reviewed and is in compliance with the Design Review Standards for Palomar Park, Section 6565-16 of San Mateo County Zoning Regulations. Specifically, the Board of Supervisors finds that the proposal: (a) minimizes tree removal and blockage of sunlight on neighboring buildings, (b) respects the privacy of neighboring houses and outdoor living areas, (c) is architecturally compatible with the neighborhood, (d) is step-designed to be compatible with the natural topography of the site, (e) has well proportioned and articulated façades, and (f) utilizes earth-tone colors comparable with the natural setting and the neighborhood. | ||||||
For the Grading Permit Find: | |||||||
3. |
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. | ||||||
4. |
That the project conforms to the criteria of the grading regulations, including the standards referenced in Section 8605. | ||||||
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 and implemented on the site. The proposed grading was prepared by a licensed civil engineer and reviewed by the San Mateo County Department of Public Works and grading is only allowed from April 15 to October 15. In addition, the project is required to get a National Pollutant Discharge Elimination System (NPDES) Permit. | |||||||
5. |
That the project, as conditioned, is consistent with the General Plan with respect to grading and minimizing environmental impacts. | ||||||
6. |
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. | ||||||
7. |
