FISCAL IMPACT:

BACKGROUND:
The proposed grading, trenching and replacement of a failing retaining wall/fence structure will be located on Assessor’s Parcel No. (APN) 194-070-083, located at 1914 Green Valley Road, in the Alamo area of the County. The subject Parcel is Parcel C of Minor Subdivision 93-86. Per the Conditions of Approval (COA) of Minor Subdivision 93-86 (COA #9H), the development rights over the natural watercourses traversing the property have been dedicated to the County of Contra Costa, a governmental subdivision of the State of California, necessitating the Board to authorize improvement on this property.
On November 29, 2023, Tom Dudley of Engineered Soil repairs submitted a Variance application (CDVR23-01062) to allow the replacement of a failing retaining wall/fence combination structure of up to 11 feet tall within the area grant deeded to the County of the subject parcel. In January of 2023, a landslide took place along the creek bank of the neighboring property and damaged the existing retaining wall/fence structure. The project is to construct a replacement retaining wall/fence structure to isolate the rear yard from the landslide on the neighbor’s property and to prevent a landslide on the subject property.
On June 25, 2024, the County Staff sent out a Notice of Intent to Render an Administrative Decision to residents within a 300-foot radius of the project site. The Notice of Intent notified the public of the public comment period. No public comment was received, and the application was approved on August 30, 2024, subject to conditions of approval by the Zoning Administrator. The approval by the Zoning Administrator determined that the project is Categorically Exempt from the California Environmental Quality Act (CEQA) under CEQA Guidelines Section §15302 - replacement or reconstruction of existing structures and facilities where the new structure will be located on the same site as the structure replaced and will have substantially the same purpose and capacity as the structure replaced. As such, the proposed project is deemed consistent with the existing uses on-site, which was approved by the Zoning Administrator. Therefore, staff recommends the Board of Supervisors authorize the grading, site improvements and to allow the replacement of a failing retaining wall/fence combination structure located at the rear of APN: 194-070-083, where the development rights have been granted to the County.
CONSEQUENCE OF NEGATIVE ACTION:
If not approved, Variance Permit County File CDVR23-01062 will be denied, and the applicant will not be able to construct a replacement retaining wall/fence structure to replace a failing retaining wall/fence combination structure as needed for the property identified as 1914 Green Valley Road in Alamo.
