Document Description
The project will increase resilience to flooding by enhancing floodplain and wetland functionality in the lower Chorro Creek watershed. The goal of the Project is to identify and develop nature-based solutions for increased floodplain resilience in the lower Chorro Creek watershed for the benefit of aquatic resources with the incidental protection of coastal communities and infrastructure.
The following Project objectives
were developed to help guide the planning and design phase of this Project:
- Enhance the overall sediment dynamics of the system to support longevity and resiliency of the Project and to manage sediment loads entering Morro Bay from Chorro Creek
- Adapt to and be resilient against the effects of climate change and sea level rise;?
- Reduce fish stranding and re-naturalize the stream channel in areas where the channel has
been captured by roads and relic swales;?
- Enhance fish passage within the Project Area;?
- Enhance the main drainage channel as a more clearly defined primary flow path to
benefit steelhead;?
- Increase area and quality of aquatic, riparian, and wetland habitats;?
- Reduce erosional pressures leading to levee and berm breaching;
- Reduce creek channel confinement and redirect flows into the natural system, indirectly
reducing overall flood water elevations across the Project Area;
- Employ co-beneficial treatment types and runoff best management practices to enhance
water quality, specifically related to water quality issues identified in the Total Maximum
Daily Load report (CCRWQCB 2024);
- Reduce peak flow, sediment loads, and debris loads on culvert and bridge infrastructure;
and
- Enhance drainage during high-flow (storm) events.
