To:

Honorable Board of Supervisors

 

From:

Marcia Raines, Director of Environmental Services

 

Subject:

EXECUTIVE SUMMARY: Consideration of an amendment to Condition of Approval No. 20 for a new single-family residence, second dwelling unit, and parcel merger, set forth by the Board of Supervisors on March 5, 2002, to allow a new fire hydrant to be installed in a different location. The project is located at 386/390 - 9th Street in the unincorporated Montara area of San Mateo County.

 
 

RECOMMENDATION

 

Approve the amendment to the Conditions of Approval approved by the Board of Supervisors on March 5, 2002, and adopt the revised Condition No. 20, as supported by the Point Montara Fire Protection District and as indicated in Attachment A.

 

PROPOSAL

 

In relation to constructing a new 2,483 sq. ft. single-family residence with an attached second dwelling unit on site, the applicant is requesting to install a new fire hydrant in a different location greater than the approved minimum distance. The proposed installation of a new fire hydrant at the southeast corner of East Avenue and Eighth Street, connecting to an existing 8-inch water main, would be a lineal distance of approximately 300 feet from the project site. Both the Point Montara Fire Protection District and the California-American Water Company recommend this location.

 

BOARD OF SUPERVISORS PRIOR ACTION

 

On March 5, 2002, the Board of Supervisors denied the appeal and upheld the decision of the Planning Commission to approve the project.

 

SUMMARY

 

Since the Board of Supervisors' approval of the project on March 5, 2002, the applicant has obtained written documentation from the Point Montara Fire Protection District that indicates support for revising the condition of approval allowing the required hydrant installation in a new location where an 8-inch water main already exists. The applicant proposes to install a new fire-district approved hydrant on the southeast corner of East Avenue and Eighth Street onto this existing water main, which is the required size for current fire suppression standards. The proposed location provides the following additional benefits by Fire District standards: (1) the hydrant will lie within an appropriate distance for fire access to the subject site; (2) the required hydrant type (Clow 960) will be installed; (3) the required 1,000 gallons per minute flow rate will be achieved; and (4) the new hydrant will provide the required flow rate to a number of other residences in the vicinity currently dependent upon an existing substandard wharf-head hydrant. The existing wharf-head hydrant located on the northwest corner of East Avenue and Eighth Street, which is the closest in proximity to the site, is incapable of supplying the required 1,000 gallons per minute flow rate because of its installation onto a 4-inch water main. Upon successful installation of the new hydrant, the applicant will be required to remove the existing substandard hydrant. The Point Montara Fire Protection District, the California-American Water Company, and the Planning Section staff all support the approval condition amendment.
