• Community meetings publicized

• Workshops conducted in each of the City’s four wards

Preparing for CRS

• Benefits of entering the CRS program: Safer better prepared community

Flood insurance discounts

Potential insurance premium savings $15,000 to $140,000 total

Range of savings per policy holder $80 to $700 per year (depending on CRS Rating achieved)

• Developed short-term and long-term implementation activities for the CRS program

• Public Outreach


4/10/201213

Stormwater Utility – Stormwater Advisory Committee

• Approximately 20 members comprised of church representatives, non-profit organizations, businesses, and residents from each ward

• Goal was to evaluate the stormwater needs for the City and carry forward the community’s and SWAC’s recommendation for a stormwater utility


• Participated in monthly meetings from June through January and participated in a field trip to view stormwater problems and solutions in the City
