Current Detention Requirements

▪ Rates vary depending on a variety of factors:

▪ Impervious surface vs. development size ▪ Adjacency to floodplain ▪ Outfall

▪ 46% counties require specific criteria to calculate detention ▪ 54% counties do not require specific criteria to calculate detention

Larger Cities

▪64 % had at least a foot or above requirement in the 100-year floodplain ▪Detention requirements vary ▪Detention rates vary from .2 to .75 acre feet per acre

Smaller Cities

Cities 25,000 and Below:

▪ Need for increased awareness of flooding issues and the permitting processes

Cities 10,000 and Below:

▪ Limited capacity to either set or enforce flood policies in their communities ▪ Refer to the county or drainage district for detention requirements

Recommendations for Consideration

Key Takeaways

▪ Need for….

▪ Cross-jurisdictional studies and cooperation ▪ Improved mapping ▪ Comprehensive and uniform detention and floodplain regulations

▪ Lack of….

▪ Compliance with current regulations and plans ▪ Ability to enforce current regulations and plans ▪ Staff capacity

Recommended Regulations

Adopting No Fill Requirement

No development or other encroachment, including fill, be allowed in a floodway which will result in any increase in the base flood elevations within the floodway during discharge of water of a base flood. No fill may be used to elevate structures in the 100-year floodplain.

Raising the Base Flood Elevation Requirement

▪ 24 inches above BFE in the 1% and .2% floodplain ▪ 36 inches or more above the depth number identified in the FIRM in all AO/ AH Zones and floodways

Recommended Regulations

Develop uniform drainage criteria manuals for all counties and cities throughout the region

Recommendations for Implementations

Recommendations for Implementation

Provide technical assistance to county and city staff officials related to NFIP , grant procurement and administration

Recommendations for Implementation

Conduct a building and construction industry-specific outreach campaign on required development regulations and procedures

Work with state advocacy organizations to promote stronger county/flood control district enforcement powers for floodplain regulations

Recommendations for Implementation

Recommended Planning

Support the development of regional flood planning efforts

▪ Identify sources of funding for future flood control and drainage planning ▪ Consolidate information from flood control planning efforts in the region and distribute to CFMs in the region

Key Lessons

• Put people first. Ensure access to solutions.
• Provide accurate public information and transparency.
• Implement policies that prepare, not just respond.
• We can’t stop flooding. Have to find ways to live with water.
• Flooding amplifies other vulnerabilities.

Put people first. Ensure access to solutions.

• Reevaluate cost-benefit rule for repairs.
• Make sure there are projects in every watershed and that we

are creating equal level of protection.

• Enable low-income families to have options.
• Consider ways to protect existing residents before making

decisions about future residents.

Provide accurate public information and transparency

• Use risk maps that take into account all types of flooding and

work for folks inside and outside the floodplain.

• Analyze the flooding issues of every watershed.
• Create rules for disclaimers and public notice.
• Empower communities to participate in decisions.

Implement policies that prepare, not just respond

• Local funds provide flexibility for buyouts.
• Remove people from harm’s way and regulate vulnerable land.
• Flood warning systems.
• Neighborhood recovery centers.

We can’t stop flooding. Have to find ways to live with water.

• Green and gray infrastructure mixture.
• Design solutions.
• Land-use planning.
• Addressing grandfathered homes.

Flooding amplifies other vulnerabilities.

• Loss of car.
• Loss of wages.
• Health impacts.
• Student mobility.
• Addressing flooding is a way to address broader resilience

goals and issues.
