Due to the fact that the lOO-year <br />floodplain is rated by FEMA in the Flood <br />Insurance Study as Floodway, all areas <br />within the 100-year floodplain boundary <br />must be kept free of encroachment. Encroach- <br />ment is defined by FEMA as, "Construction, <br />placement of fill, or similar alteration of to- <br />pography in the floodplain." The Floodway <br />must also be kept free of encroachment so <br />that the 100-year flood discharge can be con- <br />veyed without substantially increasing flood <br />heights further downstream. <br /> <br />If a structure already located in the 100-year <br />floodplain is damaged for any reason (fire, <br />landslide, or flood) and requires repairs valu- <br />ing more than 50% of market value, it will <br /> <br />BOULDER COUNTY <br />RAIN GAUGE SYSTEM <br /> <br />?a Gold Ufe <br />LUTlWC)/.I.....,S .ASIN <br /> <br /> <br />O..rll <br /> <br /> <br />Figure - 14 - Boulder CO STOIUlM SY8tem Gauge Map <br /> <br />have to be proven conclusively that there will <br />be no subsequent increase in flood levels due <br />to said improvement. <br /> <br />Without conclusive proof, repairs to said <br />property are prohibited by Town Ordinance <br />NO.1 and alternative solutions will have to be <br />sought. This land use issue is one of central <br />concern to the community of Jamestown, as <br />suitable space for development is limited and <br />the floodplain offers an attractive place to live. <br />All ordinances are available for public review <br />at the Town Clerk's office in the town hall. <br /> <br />Emergency Preparedness and Flood <br />Warning <br /> <br />Currently, Jamestown is provided some pro- <br />tection from flooding through flood warning <br />and forecasting by the National Weather <br />Service and the Boulder County Multi-Agency <br />Resource System (MARS).
