RECOMMENDATION(S):

APPROVE the Actriz Place Retaining Wall Drainage Improvement Project and AUTHORIZE the Public Works Director, or designee, to advertise the Project, Vine Hill area(s). [County Project No. 0672-6U2320 / DCD-CP#16-34] (District V).


DETERMINE the Project is a California Environmental Quality Act (CEQA), Class 1 (a) Categorical Exemption, pursuant to Article 19, Section 15301 (a) of the CEQA Guidelines, and

RECOMMENDATION(S): (CONT'D)

DIRECT the Director of Conservation and Development to file a Notice of Exemption with the County Clerk, and

AUTHORIZE the Public Works Director to arrange for payment of a $25 fee to Conservation and Development for processing, and a $50 fee to the County Clerk for filing the Notice of Exemption.

FISCAL IMPACT:

100% Gas Tax Funds.

BACKGROUND:

The purpose of this Project is to improve the infrastructure drainage of the retaining wall adjacent to Actriz Place. The retaining wall along Actriz Place runs from Actriz Avenue to Rodrigues Avenue, serves as the backyard property boundary for the residence at 471 Rodrigues Avenue and was intended to discharge at the curb in front of that residence. The wall drain is not functioning properly and has resulted in saturated conditions in the side and front yard of the residence.

The Project consists of installation of a French drain system in the backyard of the residence at the foot of the wall. The drain will discharge into an existing curb and gutter on Cabrilho Drive. The section of sidewalk at the proposed discharge location is cracked, will be replaced, and will include the necessary drain to the curb and gutter on Cabrilho Drive. Real Property transactions, including right-of-way acquisition, temporary construction easements, and drainage easements may be necessary in support of this project.

CONSEQUENCE OF NEGATIVE ACTION:

Delay in approving the project will result in a delay of design and construction and the subject property will experience saturation of both the front and side yards during coming winter months.
