Stormwater Management Services:


All new construction projects must be evaluated for compliance with the Post-Construction Stormwater Requirements, which obligates projects to treat stormwater discharges and retain stormwater on-site. North Coast Engineering staff is well-versed in these agency requirements and has completed numerous design projects with compliance objectives.

In 2013, North Coast Engineering was selected to work with the City of Atascadero to design the completion of the Charles Paddock Zoo parking lot. The project was to be a demonstration project, to display different methods of compliance in a public setting. The stormwater mitigation systems included bioswales, biofiltration areas, permeable paver sections, and overflow systems. Interpretive signs developed by the Low-Impact Development Initiative (LIDI) were installed to educate the public on the benefits of these landscape and pavement systems. North Coast Engineering staff is well-versed in the requirements of the Construction General Permit and the preparation of Storm Water
