Church Hill Drainage Improvement Project

New Braunfels Utilities
New Braunfels, Texas

Urban Civil was responsible for the design and construction of three miles of drainage channel through a predominantly developed residential and commercial area. The project included the boring of a number of drainage structures under an active rail line ranging from 48” to 54” in diameter.  The project also included approximately 1,900-ft of storm drain and culvert improvements varying in sizes from 54”-RCP to 10’X6’-RCB.  Along with the storm drainage improvement, the project required the excavation of approximately 175,000-cys to accommodate the installations of two detention ponds and a channel which at its largest point had a bottom width of 60-ft and a depth of 11-ft.  This project required the preparation of construction drawings, hydrologic and hydraulic modeling, public presentations, condemnation support, TxDOT and UPRR permitting, construction administration functions as well as legal descriptions, survey parcel maps, and expert witness testimony for right-of-way acquisition of approximately 50 parcels of land. Urban Civil also provided coordination of utility locates and potholing, obtaining permission from landowners for access to property to perform topography, set project benchmarks and control points, performed boundary surveys on all affected properties, prepared the right-of-way map with accompanying documents (overall map, individual parcel maps, metes & bounds description, closures) for City’s use in acquiring necessary right-of-way, performed hydrology and hydraulic calculations, held pre-bid conference, prepared bid opening and tabulation, performed construction administration and staking, and Plan of Record documents. Urban Civil began this project in 2002 and completed the project in 2007, while meeting the $2.5 million budget.
