Council approves subdivision improvement agreement for Hidden Hills parcel map after resident safety and geology questions

The Yorba Linda City Council approved the subdivision improvement agreement and associated bond posting for a four-lot parcel map in the Hidden Hills area after public comment raised safety, geological and documentation concerns. Resident David Ramasinski, a long-term neighbor, asked whether the Orange County Sheriff had reviewed the tentative map, questioned the developer’s track record, and flagged geological instability and a protected California black walnut tree near the project. Ramasinski also urged additional emergency staging, suggesting a second cul-de-sac would improve firefighter and police access. Staff and the developer responded that the planning commission approved the tentative parcel map on March 13, 2024, and that the current council action is to execute the subdivision improvement agreement and post required bonds so the final parcel map can be recorded once remaining conditions are met. City attorney Todd Lifton explained the subdivision improvement agreement converts the outstanding conditions into a contractual obligation requiring the developer to finish grading, sidewalks, storm drains and other improvements or allow the city to call bonds and letters of credit. The developer told council the four new lots will be single-family homes for residents (the builder said the lots were intended for the owner’s family). The developer said geotechnical reports have been prepared and peer review is underway with city staff; grading permits have not been issued yet. Council members confirmed that short-term rentals are not permitted in Yorba Linda and that design review for house plans will return to the planning commission. Staff said they would verify whether the sheriff’s department reviewed the earlier tentative map and noted the grading permit and final design review remain outstanding. The consent calendar item was pulled by a councilmember for discussion; after public comment and staff responses council members called for a vote on the consent calendar and the motion passed unanimously.
