88 Sunnyside Lane (4-Lot Residential Subdivision)
The project site is located at 88 Sunnyside Lane on one parcel totaling 24.02 acres in Orinda. The Assessor’s Parcel Number (APN) is 266-270-029. The project site is south of Briones Reservoir and north of State Route 24.
Project Status - Approved
The subdivision was approved by the Planning Commission on February 11, 2020 (view staff report here).
The project would subdivide the existing 24.02-acre lot into four parcels and develop three new single-family residences and all associated improvements. Most of the site is undeveloped and vegetated, with one existing residence on the property. One parcel would contain the existing residence, which would not be renovated or demolished as part of this project. Sunnyside Lane would be widened to accommodate fire truck access. Driveways would be constructed to access the three new residences. Utilities would be placed in an existing utility easement, which accesses the site across private property. A total of 8.1 acres of development rights on three of the parcels would be granted to the City. The project site is not included on the list of hazardous waste sites (Cortese List) compiled by the California Department of Toxic Substances Control pursuant to Government Code Section 65962.5.The parcels would range from 5.32 to 7.44 acres. The new residences’ designs have not been developed, but construction would be limited to development envelopes on each parcel. The project would increase impermeable area on the project site. Stormwater would be treated on-site by routing it through bioretention areas in undeveloped, vegetated areas. Construction activities are anticipated to begin as early as mid-2020 and last approximately 2.5 years.
