19 Hazard Type Mitigation Action Action By Potential Funding or Support Identify dam risk in area Dam -See if additional risk analysis is needed Emergency Management -See if non-reg products would be beneficial Coordinator -Talk about higher standards in dam risk CWCB areas Work with state to identify potential erosion Erosion risk zones based on new state guidance. Incorporate higher flood standards based on CWCB new risk zones. Identify claims hot spots and implement mitigation strategies such as buy outs and DOLA, FEMA drainage improvement projects. Debris Work with ongoing CHAMP efforts to consider areas for detailed study based on debris susceptibility mapping. Implement Emergency Manager CWCB mitigation measures as needed. Erosion Work with ongoing CHAMP efforts to consider areas for detailed study based on fluvial erosion zone mapping. Consider implementing more conservative Emergency Manager CWCB development standards per guidance developed for CWCB. Work with ongoing CHAMP efforts to review and adopt new flood risk analyses. Obtain a more detailed building inventory to run Hazus on rather than running it based on census tract, which can improve risk information for citizens. Use non-regulatory products, including depth grids, velocity grids, and a Percent 30-year Chance grid, for outreach assistance. Floodplain administrator, building manager, and CWCB Floodplain administrator and CWCB CWCB, DOLA CWCB, FEMA

20 Hazard Type Mitigation Action Action By Potential Funding or Support Wildfire risk is high and suppression is Fire difficult, urban loss risk is high; CAFA, CSFS Forest Restoration, Emergency Management coordination with the Colorado State Forest LSR, SFA-WUI, and DNR WRR Coordinator Service to identify what mitigation actions grants identified can be completed. Use updated draft floodplains to plan for future flood elevations and draft ways to meet mitigation actions of elevating flood prone structures and start formulating updated post-flood watershed master plan. Work with CHAMP team to identify new flood risks for multiple bridge designs identified in HMP. Use CHAMP updated study information to identify stream restoration areas and low water crossings identified in CACs and CAVs. Debris Flow Use collected data to identify debris related mitigation actions. Watershed Coordinators CWCB Would like to use information of changes in BFEs between effective and new mapping to inform stakeholders of change in risk based on inundation depth. Would like to evaluate CSLF for mapped areas to assess areas added to or removed from the floodplain. Would like to use depth and velocity grids for Zone A mapped stretches to better define the floodway area and restrict development. Boulder County Floodplain Administrator to discuss their creation with CWCB. Boulder County Floodplain Administrator to discuss their creation with CWCB.

21 Fire Hazard Type Mitigation Action Action By Potential Funding or Support Wildfire and prairie fire risk is high and suppression is difficult; Urban loss risk is Emergency Management high. Investigate mitigation actions Coordinator available through coordination with CSFS Colorado State Forest Service. Work with CHAMP team for velocity and depth grid creation based on new floodplains as identified in HMP. CWCB, FEMA Use CHAMP updated study information to identify stream restoration areas and drainage implementations identified in HMP. Use NHD layer and past flooding problem areas to identify if other streams not studied in CHAMP or CNMS should be studied. Join CRS after mitigation actions from HMP are completed and use projects to increase credit rating. Debris Flow Use identified data to identify debris- related mitigation actions. Watershed Coordinators CWCB

22 Fire Hazard Type Mitigation Action Action By Potential Funding or Support Prairie fire risk and rate of spread is high, investigate mitigation actions available through coordination with Colorado State Forest Service. Work with CHAMP team to identify new flood risks for bridge design and road construction and channel clearing identified in HMP. Emergency Management Coordinator CSFS NRCS, USACE /Outreach Work with CERC to come up with an outreach plan for talking with citizens about updated floodplains. Consider joining CRS. Use mitigation actions to gain credit for joining CRS. Want to study Box Elder Creek in Weld County. Look at model backed Zone A segments for restudy. Look into NFIP- and CFM-related training resources that FEMA can provide. Consider attending a Community Planning Workshop. CWCB, FEMA FEMA Consider acquisition of flood-prone lands and developing a post-hazard debris management plan. and Community Relations NRCS Consider developing an outreach plan, crafting answers to common questions beforehand, and designating a spokesperson or county representative. and Community Relations

23 Hazard Type Mitigation Action Action By Potential Funding or Support All Identify efforts and data sets that can be used to update plans identified in HMP Emergency Management Coordinator DOLA, FEMA, CWCB

24 Fire Fire Hazard Type Mitigation Action Action By Potential Funding or Support Wildfire risk is high and suppression is difficult; urban loss risk is high. Investigate Emergency Management mitigation actions available through Coordinator coordination with Colorado State Forest CSFS Service. Investigate ways to protect drinking water sources following a burn, or analyze flood potential from fire. Work with the CHAMP team to use new flooding to identify flood prone areas in downtown and mitigation measures identified in the HMP. After mitigation actions are completed, join CRS and use projects to obtain points. Work with the CHAMP team to identify new flood risks for multiple bridge designs and channel widening identified in HMP. Use updated hydrology data to identify storm water management measures as identified from HMP. Analyze flood risk to buildings using the new hydrology being developed for Estes. Use revised BFEs from CHAMP modeling in structural damage analysis to improve community planning for resilience. Using detailed structure information to perform Hazus modeling with the new hydrology. Leverage CERC&CWCB in outreach efforts following new hydrology and mapping. Emergency Management Coordinator CSFS Grant Via Silver Jackets Program USACE Estes Park already identified grant

27 Hazard Type Mitigation Action Action By Potential Funding or Support Debris Flow Use data to identify debris related mitigation actions. Watershed Coordinators CWCB Work with the CHAMP team to identify if there are new flood risks for bridge improvements on Railroad Ave identified in HMP. Coordinate with the CHAMP team to identify new flood risks for the Hwy 287 and Lincoln Ave bridge and other bridge projects. Consider evaluating structures at risk in Buckhorn Creek within the Loveland Fire Rescue Authority (LFRA) district. Look at the Building Code Effectiveness Grading Schedule (BCEGS) and consider Building Department how to improve the City s CRS rating. All Hazards Consider evaluating Areas of Mitigation Interest (AOMI) as a good framework for identifying land use issues. Debris Include debris flow susceptibility mapping in HMP update. Emergency Manager All Hazards Would like more structure-specific information for the Big Thompson Canyon; to have an inventory rather than a census block, to use to increase community resilience. Emergency Manager

28 Hazard Type Mitigation Action Action By Potential Funding or Support Join the NFIP and use updated flooding information to identify potential hazard areas.

29 Fire Hazard Type Mitigation Action Action By Potential Funding or Support Prairie fire risk and rate of spread is high, investigate mitigation actions available through coordination with Colorado State Forest Service. Emergency Management Coordinator CSFS Debris Flow Use data to identify debris related mitigation actions. Use floodplain data updated through CHAMP to help with assistance and outreach and locate improvement areas to minimize flood damages identified in CACs and CAVs. Coordinate with CHAMP team to use updated floodplain data to help the acquisition of identified mobile home parks and storm water improvements, as well as maintain NFIP status. After these actions are completed, account for their implementation to obtain credit and join CRS. Watershed Coordinators CWCB Reach out to FEMA and/or CWCB for assistance, if needed, and consider joining the CRS.
