1998. Cohnado FIotNJ HazanJ Mitigation Plan (409) e and multi-family homes built in these counties are inspected by OOH. In addition, the division offers a consumer information service for owners of manufactured and factory-bui~ I housing. The division selVes as the consumer com- plaint contact for manufactured housing units bui~ under the HUO Manufactured Housing Code. OOH answers questions or resolves complaints through its knowledge of factory-bui~ housing and its rapport with manufacturers. 3.2,1.3.6 Division of Property Taxation The Oivision of Property Taxation (OPT) coordinates and administers the implementation of property tax law throughout the 63 counties. It operates under the leadership of the property tax administrator, who is appointed by the State Board of Equalization (SBOE). 3.2.1.4 Department of Public Safety 3.2.1.4.1 Colorado State Patrol e The role of the stale Patrol in flood hazard mitigation is in effect during ffood emergencies. The jurisdiction of the State Patrol is mostly traffic. In flood emergen- cies the first aspect of traffic control 'NOUld be to get people out of danger, whether by vehicle or on foot. The State Patrol relies on its local people in the field, including the dispatchers, to determine that there is an emergency and then to take action immediately. There are numerous dispatch centers throughout the state. In emergency situations the local commanding officers can make decisions on what to do. Sometimes local officials (police chiefs, fire chiefs, and mayors) will call OEM requesting State Patrol and other state assis- tance. e Before a flood happens or as it starts, the intent is to move people out of hazardous areas and keep other people from entering those areas. Once a flood is in progress, or has occurred, the State Patrol's main function is to set up a command post for the disaster area. Working in concert with the OEM, the State Patrol can establish and manage these posts where communications are handled. An important function of the State Patrol is to assist in providing traffic control and security in flood damaged areas, limiting the movement of sightseers and non- essential personnel in the interests of preserving pub- lie health. safety and welfare. The State Patrol assists in identifying victims and in keeping lists of missing persons in floods. This includes handling telephone calls from all over the country. In the case of the Big Thompson flood this function was carried out by the Denver Communica- ~-3.pub ChaptBr 3 . 12 tions Center. The Patrol's auto theft unit aids in recov- ery and identification of flood damaged motor vehi- cles. 3,2.1,5 Colorado Department of Transportation The Colorado Department of Transportation (COOT) is involved in the design and construction of highways throughout the state, frequently in river valleys, so it is one state agency that is familiar with floodplain issues. Additionally, federal requirements tied to federal fund- ing of highway projects have dictated that floodplain considerations enter into the highway design process. Most Highways'in Colorado are Classified into Two Categories: 1. Federally funded highwa)'ll. and 2. Federal aid designated highways. Criteria, policies, and methodoiogies used by the COOT to design highways in floodplains are discussed below: For interstate highways, U.S. highways, and Colorado highways in urban areas, the 100-year flood is the design standard. For interstate highways outside of urban areas, the 50-year flood is the design standard. For U.S. highways and Colorado highways in rural areas, design is based on the 25-year flood or less. What discharge is used depends on a beneflllcost analysis, which considers two major factors: (a) Interruption of highway service, and (b) safety to users during a f100d event In addition, the consequences of the 100-year flood are analyzed. All of the above enter into the design cH bridges, culverts, and the highways themselves, The methodologies, including computer models, used to calculate flows are all described in the Department's Design Standards. These include Natural Resources Conservation Services (NRCS) methodology, USGS Methodology for small basins, and others. COOT uses flood histories as available. When floods occur, photographs are taken and report forms are filled oul. The Hydraulic Unit in Denver signs off on all projects throughout Colorado. They revif!NV any existing work by other agencies, such as the Colorado Wmer Con- servation Board floodplain studies, and perform any additional work necessary to design structures in the floodplain, which minimize damages. The anal)'llis is a Mo-step process. First a location analysis is done, This includes publiC Involvement and is intended as a 1/28/9610:51 PM
