<br />Thc second criteria used for prioritizing projects is the magnitude of potential <br />damage, both in loss of lifc and property, that would rcsult from potcntial flooding <br />created by inadequate facilitie~. Based on this criteria, area~ which are heavily <br />developed are more likely to suslaindamage from l100ding than are undeveloped <br />areas. The third I;riteria uscd in establishing priorities for improvement projects is <br />the need to reducc the limits of the l100dplain and make more land available for <br />future development. This criteria does not include channelizing runoff in existing <br />l100dways of undeveloped area>, but rather improvillg the capacity of existing <br />stmctures, thereby reducing backwater pondingdepths and decrea sing the limits of <br />the flood plain. The development of channels between existing structures will be the <br />responsibility of the property owner. <br /> <br />Bennett Avenue. Thereforc, it is rccommended that as its first priority, the City of <br />Cripple Creek complete the recommended Second Street tribLllary improvements. <br />The costs for these recommcndeJ improvements is approximately $460,000 which <br />may result in the improvemcnts heing consnucted over a perind greater than one <br />year. As a minimum, the first prinrity should include the new OUlfall line from <br />Warren Avenue to the north side of Bennett Avenue along with the new inlets and <br />storm sewer in Bennett Avenue and the courthouse storm sewer. The remaining <br />improvements within the Second Street tributary could be completed during <br />implementation of the priority no. 2 projeCls. <br /> <br />In October 1992, the Soil eonservation Service will release their Flood Plain <br />Management Study for the City of Cripple Creek which will include mapping showing <br />the existing flood plains. This mapping will show that several existing structures were <br />built within thc limits of the flood plains. These structures will be sLlbject to damage <br />and lhere will be some potential for loss of life should an intense thunderstorm, <br />approaching the magnitude of the design Storm, occur in the Cripple Creek or Pony <br />Gulch watersheds. The city is taking an aggressive approach towards implementing <br />drainage facility improvements, hut the resulting cost will rcquirc that these <br />improvements bc implemented over a pcriod of several years. The following is a <br />general list of project priorities the city may considcr when undertaking drainage <br />structllre improvements. It is very likely that as development continue~, some <br />adjustments in these priorities will have to be made. It is highly pussible that sume <br />of the individLwl improvements ineal;h project description can he completed by city <br />forces (Le., replacement of road crossing culverts inoutlyingar eas) hut the majority <br />of work will must likely be completed under one or more construction contracts. <br /> <br />As the business district is the most fully developed area within the city and subject <br />to the greatest amount of ongoing development, flooding and the ass ociatedproperty <br />damages are of major concern. Therefore, the city's second priurity for drainage <br />facility improvements should include completion of the Bennett Avenue storm sewer <br />system at Third Slrect and Fourth Street. These improvements should include <br />installation of all inlets, storm sewer piping and the outfal1lioes from Bennett <br />Avcnue to Cripplc Creek. <br /> <br />TIle arca ill Cripple Crcek which h.,~ histurically been ;,ubjeett:d tu the:: llll);,t frt:ljue::llt <br />flooJing: pmhlems i, the area ~urrounding the intersection of Second Street and <br /> <br />Considerable vacant grouod exists along Cripple Crcek, Poverty GLllch, the Maio <br />Street tributary and Upper eripple ereek. Developmcnt is most likely to hcgin in <br />Ihose area.~ in the near future. Due to the size ofl;onduils at existing road crossings <br />of Cripple Creek and its tributaries, an extensive flood plain is created due 10 <br />pnnding reljuiremcnts at the eonduits and potential for roadway overtopping by flood <br />flows. TIle city's third priority for drainage structure improvements should include <br />culvert replacements/improvements at each roadway crossing of eripple Creek and <br />ilS trihutaries. This work should begin at the downstream end of eripple Creek with <br />work commencing upstream until each crossing is completed. Due to the magnituue <br />of work involved. these improvcments will must likely have to be undertaken as <br />several smaller projec.ts.
