during calendar year 2019. Enhancements would include the continued ability to restore and upgrade dams and spillways associated with safety improvements as well as removal of dams to protect safety and restore natural conditions City Stormwater is currently working on an Integrated Stormwater Management Master Plan. Basin studies will be reviewed and updated as needed with further improvement needs and opportunities identified and prioritized. Reduction of flooding hazards remains a key priority for improvement projects. City Stormwater is working to help mitigate flooding throughout vulnerable areas of the City by increasing the standards by which full development occurs in a watershed. Future conditions modeling will make sure all runoff throughout the watershed is considered when each site is developed.
Develop ongoing multi-year program of detailed basin studies for each watershed in City’s jurisdiction. Fifteen basin studies are complete with 10 additional studies budgeted in the capital program. (CRS 410). Planning Commission to consider program to develop future conditions floodplain mapping for all FEMA mapped areas (this is already done for non-FEMA mapped areas). The program would consist of a multi-year capital program for mapping for all development regulations in these areas. Future conditions would be based on expected development per the Comprehensive Plan and zoning maps. FEMA streams in the ETJ and consideration of changes to

C.2.2 Property Protection Measures Property protection measures are used to modify buildings or property subject to damage. Property protection measures fall under three approaches: • Modify the site to keep the hazard from reaching the building; • Modify the building (retrofit) so it can withstand the impacts of the hazard; and • Insure the property to provide financial relief after the damage occurs. Property protection measures are normally implemented by the property owner, although in many cases technical and financial assistance can be provided by a government agency. Keeping the Hazard Away Generally, natural hazards do not damage vacant areas. As noted earlier, the major impact of hazards is to people and improved property. In some cases, properties can be modified so the hazard does not reach the damage-prone improvements. For example, a berm can be built to prevent floodwaters from reaching a house. Flooding There are five common methods to keep a flood from reaching and damaging a building: • Erect a barrier between the building and the source of the flooding.
