Novato Creek Bypass Study Project

active

Mapping and inspections of storm drains, drainage ditches and other facilities in Nave Gardens was completed in 2021. A draft scope for a hydraulic study focusing on the bypass system around this area was prepared for Advisory Board consideration.  Water level gauges were installed in fall 2022, with the rain events of winter 2022/2023 providing good data for the model development. This study builds on the Novato Watershed Study, City of Novato storm drain model, and Countywide LiDAR surface data to better analyze  Novato Creek and the flood bypass system from Arroyo Avichi near South Novato Blvd through Baccaglio Basin, Scottsdale Marsh, and Lynwood Basin. The purpose of the Novato Creek Bypass Study is to identify opportunities along Novato and lower Warner creeks and through the bypass drainage system for new flow gates, perimeter barriers, pump stations, and increased stormwater detention that would reduce flood risk in downtown Novato and Nave Gardens.
