Meridian Village WW Reuse Dam, (DAMID 080457) July 19, 2017 <br /> Jurisdictional Status Et Hazard Classification Page 9 of 9 <br /> Conclusions <br /> According to the Guidelines for Hazard Classification Analysis (SEO, 2010), a dam is <br /> considered High hazard when loss of life is anticipated. In this case, no residential structures <br /> are anticipated to be impacted. Additionally, the traffic rates on Chambers Road are low and <br /> visibility is good, so drivers should be able to recognize and avoid a life threatening flood <br /> situation. Therefore, a High hazard classification is not appropriate. <br /> Minimum criteria for a Significant Hazard classification includes flood depths or the product <br /> of depth and velocity at developed infrastructure exceeding 2 feet and 7, respectively. The <br /> peak flood depth over Chambers Road during the foundation breach scenario is marginally <br /> greater than 2 feet and the depth-velocity product reaches 10, therefore the minimum <br /> criteria has been exceeded and a Significant Hazard classification should be considered. <br /> However, Chambers Road is presently a 32 foot wide 2-lane asphalt paved road with concrete <br /> curb Et gutter and a concrete pedestrian sidewalk on the west side. The road is constructed <br /> at-grade except where the culvert passes under the road. At that location, the very short <br /> road "embankment" is 240 feet wide. The road is currently under construction to add a <br /> separated 2-lane northbound with a dividing median. The final road width is anticipated to <br /> be around 90 feet. <br /> Based on the geometry described above, the breach flood is not anticipated to have a <br /> significant impact on Chambers Road and a Significant Hazard classification is not <br /> appropriate. Therefore, the Meridian Village WW Reuse Dam has been assigned a Low <br /> Hazard classification. <br /> 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 www.water.state.co.us Nam: <br /> John W.
