8/26198 Emergency Preparedness and Flood Warning Spotter network for Canon City One of the most exciting opportunities for flood hazard mitigation in is the development of a local spotter network. A network of se- lected volunteer observers in the vicinity could be designated to monitor rainfall amounts and stream levels in the Canon City watersheds. This network of manned r,,;nfsll observation stations would monitor local rain- fall with standardized Rain Gauges so all re- cords could be correlated and compiled into evidence for informed decision-making, In this proposed system, records would be kept of daily rainfall but only heavy rainfall accumulations would be relayed to a desig- nated coordinator who could then effectively calculate the potential for flood hazard. Rain- fall information would be supplemented by stream gauges placed at strategic points along the major tributary streams. Floodproofing for Business and Homeowners Many of the floodproofing techniques that keep water away from a residence, such as flood walls, levees, and structural sealing, may require special treatment for openings such as doors, windows, driveways, etc. These closures act as shields to cover the gap and prevent water from entering, and can be of a variety of shapes, sizes, and materials. In some cases closures are permanently at- tached using hinges so that they can remain open when there is no flood threat. They may be portable, normally stored in a convenient location and slipped into place when a flood threatens, In certain situations, when flood- Canon City Flood Hazard Mitigation Plan ing is of very low level, usually less than one foot, some method of enclosing low entrances such as basement doors or window wells might be a satisfactory option. In any case, there are a number of elements involved in d~signing and using a closure system. In areas of shallow, low velocity flooding, clo- sures can be used on doors, windows, vents, and other building openings. However, the first step with the use of closures placed di- rectly on buildings is to be certain that both the closure and the wall systems are strong enough and sufficiently watertight to with- stand flood pressures. The use of closures directly on a structure is considered to be part of the sealing process. Closures can be considered as an option only if a flooding situation provides sufficient time to install the closures. The need for both warn- ing time and "human intervention" is critical, since all closure system require personnel to install them and make certain they are prop- erly sealed. Closures that are stored between floods must be readily accessible. The effectiveness of an entire closure system will be compromised if the closures are stored such that flooding ren- ders them inaccessible, or if even one closure is improperly installed.
