<br />- 3- <br /> <br />the TAC embrace the concept of this Operating Principle, which allows communities to have <br />more flexibility in their floodplain management programs. <br /> <br />Critical Facilities (Operating Principle #8) <br />The basic concept of this Principle is to suggest to communities that construction of all critical <br />facilities (i.e. hospitals, police and fire stations, nursing homes, etc.) occur outside ofthe SOD-year <br />floodplain. This concept has been implemented in other States and in other countries worldwide in <br />order to protect vital facilities and infrastructure where flood losses would be socially <br />unacceptable or where flood losses would yield catastrophic outcomes. Staff has witnessed and <br />documented the devastating consequences (i.e. Buffalo Creek 1996 and Fort Collins 1997) where <br />critical facilities were unfortunately damaged or destroyed. This Operating Principle does not <br />mandate or require any action by communities or developers, but rather brings to light the risks <br />associated with placing essential structures in hann's way. The CWCB staff and T AC support the <br />concept of this Operating Principle. <br /> <br />Stormwater Detention (Operating Principle #10) <br />The basic concept of this Principle is to recommend that government entities require adequate <br />stormwater detention in cases where land development projects change (increase) the runoff <br />characteristics of the affected drainage basin. The stormwater detention facilities should be <br />adequately designed and constructed by the development proponents to mitigate any increased <br />flow values. The Principle also discusses that flood detention benefits can be recognized in flood <br />studies for those detention sites that are publicly owned, operated and maintained or for those <br />facilities that are privately owned but publicly controlled. In contrast, flood detention benefits <br />from those facilities that are not publicly owned or publicly controlled may not be recognized. <br />The CWCB staff and the T AC support the concept of this Operating Principle. <br /> <br />The contents and objectives of the remaining Operating Principles did not seem to elicit controversy or <br />concern by the Board, and therefore the were not significantly changed by staff. <br /> <br />Additional Information <br />The following attachments are provided to allow for a better understanding and explanation ofthis very <br />important project: <br /> <br />.
