Pursue acquisition or elevation of repetitive loss buildings and other flood prone structures. Respond to requests and questions from citizens regarding actions they may take to improve drainage, halt erosion, and to relocate, renovate or retrofit structures being flooded. Install backup generators for critical facilities.

C.2.3 NATURAL RESOURCE PROTECTION Resource protection activities are generally aimed at preserving (or in some cases restoring) natural areas. These activities enable the naturally beneficial functions of fields, floodplains, wetlands, and other natural lands to operate more effectively. Natural and beneficial functions of watersheds, floodplains and wetlands include: • Reduction in runoff from rainwater and stormwater in pervious areas • Infiltration that absorbs overland flood flow • Removal and filtering of excess nutrients, pollutants and sediments • Storage of floodwaters • Absorption of flood energy and reduction in flood scour • Water quality improvement • Groundwater recharge • Habitat for flora and fauna • Recreational and aesthetic opportunities As development occurs, many of the above benefits can be achieved through regulatory steps for protecting natural areas or natural functions. This section covers the resource protection programs and standards that can help mitigate the impact of natural hazards, while they improve the overall environment. Six areas were reviewed: • Wetland protection • Erosion and sedimentation control • Stream/River restoration
