Stormwater Capture & Infiltration
Benefits:
Flood Control – stormwater capture reduces likelihood stormdrains will become overwhelmed Urban Runoff Water Quality – reduces pollutant loading into receiving waters Santa Monica Bay
Dominguez Channel
Conservation of Resources – drought resilience by storing water in the soil and recharging groundwater Meets regulatory compliance commitments
Regulatory Compliance
LARWQCB NPDES Permit
Requires BMPs to reduce pollutant loading into receiving waterbodies (trash, bacteria, metals, nutrients, oil, pesticides) Requirements apply to both private developments and City owned parcels and CIP Projects included in the WMP Typical private property LID capture & infiltrations strategies Infiltration galleries & wells
Permeable pavers/surfaces

Possible Options to Expand Stormwater Capture
Direct more discretionary capital resources to the unfunded stormwater capture projects in the CIP and WMP Update the Council’s 2006 Administrative Policy and Municipal Code to require stricter requirements by lowering the threshold of specific project types that require LID measures Codify an in-lieu fee option for applicants to fund a larger, regional stormwater capture BMP vs smaller, localized BMPs Pursue additional grant funding
Direct staff to study potential fees to fund future stormwater capture projects
