Green Infrastructure elements will include:

Trash Capture

DSBB

An underground trash capture device will be installed under Goldentop Road to remove trash and debris from stormwater runoff before it enters the storm drain system, which discharges to the San Dieguito River and ultimately the Pacific Ocean.

Natural Solutions

MWS

A modular wetland system will be installed to improve water quality by filtering runoff through native plants and soil, removing pollutants such as bacteria—mimicking the natural cleaning process found in nature.

Construction: What to Expect

Construction began in Summer 2025 and will be completed in Winter 2026.

Please note that construction dates are subject to change due to compliance requirements, inclement weather, and/or other unforeseen circumstances. 

During construction, the County will make every effort to minimize disruptions along Goldentop Road. Most work will occur outside of the public road right-of-way, reducing impacts to local businesses and traffic. However, there will be instances when lane closures and parking restrictions are necessary. There will also be temporary impacts to utilities, and to both vehicular and pedestrian traffic. Traffic control measures, including signage placed prior to and during construction, will be implemented to ensure the safety of our customers.
