Please refer to the attached handout, which details the BMPs.
|
|
|
|
|
11.
|
The applicant shall submit an erosion control plan, prior to the issuance of a building permit, to mitigate any erosion resulting from project-related grading activities.
|
|
|
|
12.
|
No site disturbance shall occur, including any grading or vegetation removal, until a building permit has been issued.
|
|
|
|
13.
|
The applicant shall provide "finished floor elevation verification" to certify that the structure is actually constructed at the height shown on the submitted plans. The applicant shall have a licensed surveyor or engineer establish a baseline elevation datum point in the vicinity of the construction site. The applicant shall maintain the datum point so that it will not be disturbed by the proposed construction activities until final approval of the building permit.
|
|
|
|
|
|
|
a.
|
The datum point and its elevation shall be shown on the submitted site plan. This datum point shall be used during construction to verify the elevation of the finished floors relative to the existing natural or to the grade of the site (finished grade).
|
|
|
|
|
|
|
b.
|
Prior to planning approval of the building permit application, the applicant shall also have the licensed land surveyor or engineer indicate on the construction plans: (1) the natural grade elevations at the significant corners (at least four) of the footprint of the proposed structure on the submitted plan, and (2) the elevations of proposed finished grades.
|
|
|
|
|
|
|
c.
|
In addition, (1) the natural grade elevations at the significant corners of the proposed structure, (2) the finished floor elevations, (3) the topmost elevation of the roof and (4) garage slab elevation must be shown on the plan, elevations, and cross-section (if one is provided).
|
|
|
|
|
|
|
d.
|
Once the building is under construction, prior to the below floor framing inspection or the pouring of the concrete slab (as the case may be) for the lowest floor, the applicant shall provide to the Building Inspection Section a letter from the licensed land surveyor or engineer certifying that the lowest floor height, as constructed, is equal to the elevation specified for that floor in the approved plans. Similarly, certifications on the garage slab and the topmost elevation of the roof are required.
|
|
|
|
|
|
|
e.
|
If the actual floor height, garage slab, or roof height, as constructed, is different from the elevation specified in the plans, then the applicant shall cease all construction and no additional inspections shall be approved until a revised set of plans is submitted to and subsequently approved by both the Building Official and Planning Director.
|
|
|
|
|
14.
|
The project's design shall include the use of double pane windows, solid core exterior doors, and weather stripping to lower the interior noise level.

|
The applicant shall obtain a building permit prior to initiating any construction or grading activity on site.
|
|
|
|
16.
|
The building plans shall meet with the approval of the California Department of Forestry and Fire Protection District.
|
|
|
|
17.
|
There shall be no removal of any significant vegetation that screens the view of the proposed project.
|
18.
|
The applicant shall submit a landscape plan in accordance with the "Landscape Plan Guidelines - Minimum Standards" for review and approval by the Planning Director. The applicant's biologist shall confirm that the plans have been reviewed prior to submittal to the Planning Division. The goal of the required landscape plan is to soften the impact of the building from the street and the sides. The plan shall include a minimum of five (5) trees in the front and three (3) trees on the right side of the property. The trees will be at least 15-gallon size, and they shall be located in such a way as to block the view of the development to the extent possible from the Cabrillo Highway and adjacent southern property. A minimum of forty (40) shrubs shall be included in the design for the front and right side of the residence. Areas in the front of the property that do not contain trees, shrubs, or landscape shall be planted with groundcover. An irrigation plan for the front area shall be submitted with the planting plan. Upon submittal of the landscape plan, the applicant shall pay a review fee based on the fee schedule in effect at that time.
|
|
|
|
19.
|
The approved landscaping plan shall be implemented before the Planning Division gives a final approval on the building permit and before the applicant schedules a final inspection.
|
|
|
|

|
|
22.
|
The applicant, for the protection of the riparian corridor, shall install "limit of work" fencing, at least 50 feet from the outside edge of the wetland areas. Fencing to exclude all construction activity (including well and septic system construction) should also be designed as an effective barrier for the San Francisco Garter Snake and California Red-Legged Frog. The maximum areas of potential habitat on-site that are not within the development envelope should also be protected from construction.
|
|
|
|
23.
|
To reduce dust emissions during project construction, unpaved construction areas shall be sprayed with water as often as needed to keep soil moist. It is anticipated that this mitigation measure could reduce dust emissions by as much as 50%. Air quality standards are regulated by the Bay Area Air Quality Management District and violations can be reported to the agency.
|
|
|
|
24.
|
All new construction within this area is required to be designed and constructed to withstand seismic activity pursuant to State and County Building Codes.
|
|
|
|
25.
|
The applicant shall incorporate into the building plans a filtering mechanism of adequate capacity to filter all chlorine and other chemicals from all water discharged or drained from the pool and two spas.
