The Flatiron Property is located south of US Highway <br />36 (Boulder Turnpike) at Foothills Parkway, east of Highway 93 and west of South <br />Boulder Creek. Please refer to the Vicinity Map, Figure 1. The Property is adjacent to <br />South Boulder Creek's lOO-year floodplain as defined by the Federal Emergency <br />Management Agency's (FEMA) Flood Insurance Rate Map (FIRM) dated June 2, 1995, <br /> <br />The existing floodplain review undertaken by Love & Associates, Inc, and the additional <br />hydraulic modeling performed was confined solely to the impacts of the South Boulder <br />Creek lOa-year floodplain on the Flatiron Property. Following is a brief summary of the <br />scope of work for this project. <br /> <br />A. Review the FEMA regulatory hydraulic model (HEC-2) for accuracy as regards <br />the Property, <br /> <br />B, Prepare hydraulic models for two site conditions relating to the Flatiron Property <br />which can be described as follows: <br /> <br />* Condition 1, lOa-year South Boulder Creek floodplain with an interior <br />200-foot wide interceptor channel and no FEMA certified flood levee in place. <br /> <br />-1- <br />
