<br />These capabilities and experience are important to have on this project in order <br />to directly and quickly identify special flooding concerns and/or to diagnose <br />flooding phenomena from first hand accounts. The physical understanding <br />together with a direct knowledge of the level of detail and limitations inherent with <br />various types of flood studies puts Ayres Associates in an excellent position to <br />complete these floodplain study review for the CWCB. <br /> <br />Project Approach <br /> <br />We understand that the project scope is to technically review approximately half <br />(thirty, plus or minus) of the existing "undesignated" Colorado floodplain studies, <br />emphasizing West Slope areas. Furthermore, we understand the specific entities <br />and waterways which will be included in the scope of work are yet to be defined <br />as one of the initial tasks once work begins, <br /> <br />We fully appreciate the value of the work of the eWCB is und,ertaking through <br />our own experience dealing with "approximate" floodplain delineations and <br />locations where the flooding characteristics are actually more complex than they <br />were considered when initially evaluated. These unstudied and incompletely <br />studied areas can present more difficulty than benefits when they have obvious <br />deficiencies which even laypersons can identify. The known lack of creditability <br />becomes even more of a difficulty when this information is adopted as an <br />institutional basis for regulation. Consequently, these reviews are expected to <br />address: <br /> <br />· Consistency and accuracy of technological methods (hydrology and <br />analytical documentation of flood elevations) <br />· Better site specific attention to special flooding circumstances (spatially <br />varied flows, ice jamming, alluvial fans, etc) <br />· Clear recognition of the risk of flooding to existing inhabited areas <br />· Better attention to developing areas to enable more proactive handling <br />of potential flooding <br />· Mapping availability and accuracy <br /> <br />Expected findings and conclusions include: <br /> <br />· Highlighting of special health and safety flood hazards and risks for <br />public awareness <br />· Need for further study, better mapping, greater geowaphical coverage <br />to be accomplished in future analyses <br />· Identification of specific problems/inconsistencies in the accuracy of <br />existing information <br />
