<br />Jim Koogler. P.E.. CFM <br /> <br />assist the San Jacinto River Authority in issuing early warning and notification messages to responsible <br />downstream emergency management authorities of the emergency situation. <br /> <br />Legends Ranch - Montgomery County, Texas: Mr. Koogler is responsible for the master drainage plan <br />and implementation plan for the Legends Ranch Development in southern Montgomery County. The <br />1400+ acre project will include single family, commercial and park area in the Woodsons Gully <br />watershed in southern Montgomery County near The Woodlands, Texas. The project involves <br />determination of the baseline hydrology and hydraulics, drainage infrastructure plan, pump detention <br />facilities, preparation of the LOMR., and determination of an implementation plan. A unique feature of <br />this project involves the design of the 450 ac-ft regional detention basin with a 200,000 gpm stonnwater <br />pump facility. The pumps include a small jockey pump, one (1) nO-horsepower 20,OOO-gpm pump, one <br />(1) 170-horsepower 30,000-gpm pump, and three (3) 315-horsepower 50,OOO-gpm pumps. The pumps <br />are close-coupled units with axial propellers in a wet well installation. Auxiliary power is provided by <br />diesel fuel generators. Digital terrain models were developed using LIDAR. to produce topographic map <br />data. The planning portion of this project includes the application of the selected hydrologic approach <br />for modeling various phases of development, and design of drainage channels and detention to facilitate <br />future development. <br /> <br />Houston Airport System, Westside Wetland Mitigation Project: Performed the water budget analysis <br />and the hydrologic and hydraulic analysis for the system of wetlands created at the former westside <br />airport property in eastern Waller County, Texas for the Houston Airport System. Design responsibilities <br />included creation of a series of non-forested prairie wetlands and supporting prairie upland habitat and the <br />associated outfall structures and spillways. A water budget analysis was conducted to determine the <br />feasibility of maintaining the series ofwet1ands on the project site. Hydrologic models were developed to <br />evaluate potential hydrologic impacts on surrounding areas upstream and downstream form the site. The <br />wetland creation compensates for the wetland impacts resulting from the construction and operation of <br />proposed runway 8L-26R and associated near-term master plan projects at the George Bush <br />Intercontinental Airport. <br /> <br />Benders Landing Development Master Drainage Plan - Montgomery County, Texas: Mr. Koogler <br />performed the hydrologic and hydraulic analysis and developed the implementation plan for the system of <br />canals and lakes within the 1100 acre single family residential development. Digital terrain models were <br />developed using a combination ofLIDAR and conventional field survey to determine field conditions and <br />develop cross sections. The system of canals and lakes are designed to prevent flooding and to lower the <br />base flood elevation (BFE) to within banks. Stormwater detention is included on top of the normal pools <br />of each amenity lake and canal. A request for Conditional Letter of Map Revision (CLOI\.1.R) from <br />FEMA was prepared to revise the floodplain through the site. A water budget analysis was conducted to <br />determine the feasibility of maintaining the series of amenity lakes. <br /> <br />Riverwalk Subdivision - Montgomery County, Texas: Project elements of this 1600+ acre single <br />family residential development consisted of design of the water supply plant, water distribution system, <br />development of a master drainage plan. roadway design and construction inspection. Riverwalk <br />subdivision will ultimately include a 60+ acre lake and attendant recreational facilities. The projects <br />hydrologic and hydraulic impacts were analyzed using the HEC-l and HEC-2 programs. <br /> <br />Riley FnzzeI Rd/Grand Parkway - Harris County, Texas: Mr. Koogler performed the hydrologic and <br />hydraulic analysis and design associated with the roadway drainage system and the proposed bridge at <br />Spring Creek. Spring Creek drainage analysis and design included: hydraulic impact analysis to Spring <br />Creek (HEC-2/HEC-RAS), bridge scour analysis, preparation of the CLOMR., and floodplain cut and fill <br />balance calculations. Local drainage analysis included ''in-line'' stormwater detention provided in <br />roadside ditches and analysis and design of cross drainage structures. <br /> <br />Espey Consultants, Inc. <br /> <br />Exhibit A, Page 73 <br /> <br />Page 2 of 4 <br />
