Flooding – Rainfall-induced

Limit/control amount of impervious surfaces Max. infiltration (look at zoning regulation if can't add to stormwater ordinance) Reduce threshold for stormwater quantity control and consider improvements to streams: increase quality control, improve incentives for current roles to increase quantity and infiltration Integrate combined surface and groundwater impacts into the evaluation of at-risk infrastructure and the prioritization of adaptation improvements. Green infrastructure, green roofs, rain barrels (trees, improve stormwater infrastructure, improve LID/green infrastructure) Review Level of Service (LOS) standards for stormwater across the region by doing a comparison of design standards. For example, low LOS standards upstream can negatively affect a neighboring jurisdiction Conduct habitat, stream and floodplain restoration on properties purchased through floodplain buyouts. Use local climate projection data to understand the risk of failing culverts in future years. Weigh the economic, societal and environmental costs against the benefits of installing new culverts. Implement stormwater projects that reduce pollution and capture local water supply. Develop a watershed plan to guide infrastructure and improvement projects. Watershed plans can influence zoning and prompt infrastructure evaluations and stream restoration. Identify open space that could function as water storage areas. Increase/require use of Low Impact Developments. Encourage local government departments and local employers to offer remote work during extreme weather events to make economic activity and critical services less vulnerable to disruption. Assist lower- and moderate-income homeowners with retrofitting projects by developing funding programs or facilitating access to funding resources. Review existing legal, regulatory and policy frameworks that govern floodplain mapping, flood insurance and flood mitigation. Identify opportunities to improve their usefulness to reduce risks and increase Reduce flooding by targeting stream restoration in gullies that are most affected by fluctuations in water volume. Develop a flood early warning system that uses gauges in strategic locations to monitor water levels. The system would provide alerts when roads may be flooding. Use the system to let people know when Implement new maintenance initiatives to improve performance of existing stormwater systems. Incentivize measures for flood mitigation in construction areas in the floodplain. One example is offering a structure elevation grant. Implement flood detection devices, alerts, warnings and reporting systems. Create and implement a localized flood management master plan. The plan could identify detailed mitigation options such as storage areas, stream restoration needs and buyout priorities.
