Three Examples of Flood Mitigation Opportunities Spotter network One of the most exciting opportunities for flood hazard mitigation in Jamestown is the proposed development of a local spotter net- work for flood warning. This network of se- lected volunteers could be designated to monitor rainfall amounts and stream levels in the watersheds directly affecting Jamestown. Rainfall observation stations would monitor local rainfall with standardized Rain Gauges so all records could be accurately correlated and compiled into evidence for informed deci- sion-making by the JVFD. In this proposed system, daily rainfall records would be kept, but only heavy accumulations would be relayed to a designated coordinator who would then calculate the potential for flood hazard. Rainfall information would be supplemented by stream gauges placed at strategic points along the major tributary streams - the James and the Little James. The spotter network concept is currently un- der consideration by the JVFD, and the Fire Chief, Tim O'Dair has drawn up a newly pro- posed Flood Evacuation Plan (see Appendix D) that reflects the usefulness of the added information provided by the proposed spotter network. Advantages of this new plan include greater autonomy for the JVFD, better records of rain - fall eventsfor the community, and more effec- tive localized flood prediction. The community would be provided with specific information regarding rainfall in the watersheds directly affecting Jamestown. Improvement to Ward Street Culvert This mitigation proposal is clearly structural and will require funding from outside sources. It is clear, however, from a review of historical events and the simplistic design of the em- bankment that this structure will very likely blow-out in a 100-year flood event. The culvert crossover was totally destroyed out in the floods of 1894, 1913 and 1969. In the 1969 flood, debris from the culvert added to the impact which destroyed the Anderson Street bridge. It also contributed a great deal of debris which jammed under the Main Street bridge and diverted the raging floodwaters down Main Street.

The meeting would also provide an open forum for the discussion ofland use concerns and the National Flood Insurance program in Jamestown. A flood- proofing workshop for homes and businesses may also be conducted at the same time with representatives from the Colorado Water Conservation Board (CWCB). 15
