Updated: Oakley Neighborhood Could See 176 More Homes

The Oakley Planning Commission is set to discuss the Stonecreek Subdivision which could bring 176 single-family homes to the City of Oakley.

During its March 3 meeting, the planning commission will look at a recommendation on the 50.5 acre project which includes 176 single-family residential lots, a 2.4-acre park, a 2.7-acre detention basin, a 1.1 acre, 75-foot wide creek setback and other improvements.

The project is located on the west side of Sellers Avenue, approximately 0.5 miles north of Delta Road and 1 mile south of East Cypress Road, located southwest of the intersection of Kings Canyon Way and Sierra Trail Road.

This project dates back to 2005 when the rezone occurred.

According to the staff report, in 2006, the site was graded in preparation for the project development, however the residential project did not move forward with vertical development, and the approved Tentative Map has since expired. The applicant submitted a new application for a Vesting Tentative map in 2023. The density range of 2.3 to 3.8 dwelling units per gross acre falls within the allowed density range – allowing between 101 units to a maximum of 176 units.

Update – approved by Oakley Planning Commission

March 3 Update – Q&A w/City Manager

According to City Manager Josh McMurray, here is some additional information in how this project relates to other timelines:

• Laurel Road Extension – will this be completed before or after construction of this development?  Undetermined.  The City is actively seeking funding for the Laurel Road Extension Project, and the timing of the housing development is subject to the future developer’s schedule and market conditions.  The project is conditioned to pay Traffic Impact Fees which covers their fair share for cumulative traffic impacts.
• If Laurel Road is not complete prior to subdivision, the traffic from not only the neighborhood on Teton, but Quail Valley and even Creekside Park will now be on Teton to Sellers as a backway out of Oakley.   Comment noted.  Traffic calming features are analyzed and approved by the Public Works and Engineering Department during the design phase.
• Sellers Road – will this entrance be the main entrance for construction?  Or down Laurel to Teton?  Sellers Road will be the main entrance for construction.  Condition 25 requires approval of a Traffic Control Plan.
•  Sellers Road and this development – will this be a 3-way stop?  No.  One stop sign to be installed for exiting the subdivision onto Sellers.
• Main St & Delta Rd traffic signal – will this go in before, after or during construction? Can this be made a condition upon approval?  City currently designing the signal project.  Project is conditioned to pay Traffic Impact Fees which would contribute the project’s fair share of cumulative impacts to this intersection.
• Main St & Laurel – there is basically no right hand turn lane coming out of the neighborhood due to this being a 2-lane road. This will cause significant backup. At some point will this be expanded this. My hunch is at some point, you will have a ton of cars during peak hours backed up from Main St to Creekside park.   The segment of Laurel Road from Main Street to Teton is shown as a 4-lane arterial in the City’s General Plan.  The City continues to monitor traffic signal and timing and make adjustments as needed.  City will continue to seek grant funding for the project and acquire the necessary right of way to widen this section of Laurel Road.
• Future plans on Sellers Road… is the county/Oakley looking at safety updates/upgrades to ensure Sellers can handle all the traffic from E Cypress Road and now this development access point?  Per the General Plan, Sellers Avenue  is planned to be a 4-lane road north of Laurel and remain 2-lanes south of Laurel.  The General Plan is based on build out.  Right of way is acquired and frontage improvements are done as development is approved and constructed.

Project Description

The Stonecreek Subdivision 9647 Project would subdivide the project site into 176 single-

family residential lots. On-site improvements would include approximately one acre of open space within a 75-foot setback from Marsh Creek, a 2.43-acre park in the northwest corner of the project site, and a 2.7-acre stormwater detention basin in the northeast corner of the site. An internal roadway network would connect to existing roadways to provide site access, including Teton Road and Kings Canyon Way to the north of the site and Sellers Avenue to the east. Each lot would range in size from 6,000 square feet (sf) to 16,182 sf, and utility improvements would be included on-site and within the surrounding roadways. Frontage improvements would include a 26-foot-wide roadway dedication along the Sellers Avenue frontage to the east. The project would include removal of the existing remnant foundations and on-site trees would be removed. The proposed project would require approval of a Vesting Tentative Map.

The Vesting Tentative Map would result in a subdivision of a total of 179 lots comprised of 176 single-family residential lots, Parcels A, B, and C, as well as an internal roadway network that would connect to the surrounding roadways. The single-family lots would range in size from 6,000 sf to 16,182 sf. Parcel A would function as a setback parcel adjacent to Marsh Creek. It serves the purpose of creating a 75-foot-wide buffer from the top of bank along the east side of Marsh Creek, which is a requirement of the East Contra Costa County Habitat Conservation Plan/Natural Community Conservation Plan. Parcel B would be reserved in the northwestern corner of the project site for the future 2.43-acre park that would be combined with the 1.09-acre parcel to the north to form a single park, and Parcel C would include the 2.7-acre stormwater detention basin in the northeast corner of the project site. The three parcels would be dedicated to the City on the Final Map. As proposed, the gross density (including all area before right of way dedication, parks, landscaping, etc.) would be approximately 3.5 du/ac.

Site Access and Circulation

An internal roadway system would be constructed throughout the project site to provide access to each unit. The internal roadways would be within a 56-foot right-of-way (ROW) and would include a five-foot sidewalk, five-foot landscape strip, eight-foot parking, and a 10-foot travel lane in each direction. Primary vehicular access to the site would be provided from Kings Canyon Lane and Sierra Trail Road north of the project site which would also connect the project to the subdivision to the north, and Sellers Avenue to the east. The other internal roadways would be stubbed to the south and west of the project site. The stubbed out roads could potentially be designed into the undeveloped and existing properties along the south at a future date

Frontage Improvements

The proposed project would include frontage improvements within a 0.37-acre area along Sellers Avenue to the east, primarily comprised of a 26-foot-wide roadway widening and dedication (see Figure 5). The roadway widening area would include two six-foot-wide landscaping areas on either side of a six-foot-wide sidewalk, an eight-foot-wide bicycle lane, and two approximately 12-foot-wide travel lanes. The proposed residences along the eastern site boundary (Lots 103 through 109) would be separated from the frontage improvement area by a landscape privacy wall. In addition, the proposed frontage improvements would include eight feet of space as a buffer between the easternmost landscaping area and the existing roadway. It should be noted that the existing roadway includes a five-foot buffer. Following construction of the frontage improvements, the total roadway buffer would be 13 feet wide.
