Water Infrastructure – Stormwater

Update the Intensity, Duration and Frequency (IDF) curves used by stormwater infrastructure designers to inform the sizing of new capital improvements based on latest precipitation data. Review the capacity of existing drainage structures to understand their ability to manage increased precipitation projections. Identify the likelihood and consequences of impacts to this infrastructure Evaluate mechanisms to support private property owners in making drainage improvements in landslide prone areas. Prioritize the needs of communities of Implement new maintenance initiatives to improve performance of existing stormwater systems. Provide incentives (density bonuses, permitting fees, faster review process, etc.) to developers to reduce impervious surfaces beyond riparian buffer rules and leave riparian areas in place. Identify funding for and routinely clean and repair stormwater drains. Encourage farmers to help manage stormwater runoff. For example, farmers can increase soil organic matter for better drainage, shift production to more highly drained soils and install tile drains. Incentivize private property owners to implement green infrastructure (GI) and stormwater best practices through a reduced stormwater fee incentive program, zoning or other mechanisms. Encourage GI installations Green infrastructure, green roofs, rain barrels (trees, improve stormwater infrastructure, improve LID/green infrastructure) Account for projected changes in precipitation and sea level rise in water and water infrastructure planning. Increase water infrastructure diversion to reduce the likelihood of sanitary sewer overflow. Examine regionalization efforts and sharing of resources for all water utilities. Convene a forum to conduct a joint assessment and planning strategy. Involve local water utilities, wastewater service providers, water managers and other partners to achieve a coordinated consideration Protect surface and groundwater from contamination. Develop and implement a jurisdiction-wide green infrastructure plan that supports vegetation-based stormwater management best practices and strategies for managing urban heat. Use green infrastructure in public spaces and streets to reduce stormwater runoff in historically underserved neighborhoods. Form a stormwater utility that can create fee-based services to help pay for flood risk reduction projects. Identify the locations of water distribution, water treatment and stormwater infrastructure. Monitor their conditions (i.e., age, material integrity). Note that subsidence can negatively affect water Identify lift stations and force mains that may be impacting raw water supply (e.g., force mains that transport sewage across lakes). Address flood-prone roads by installing green stormwater practices.
