TANNERY BROOK DRAINAGE STUDY
East Aurora, NY

KEY PROJECT COMPONENTS:
• Hydraulic and Hydrologic Study
• Hydraulic Analyses
• Cost Estimates
• Priority Analysis

TVGA was contracted by the Village to perform a hydrologic and hydraulic study at the five critical culvert sites, complete with recommendations for a replacement program based on a priority analysis.

For each of the culvert sites, drainage sheds were defined and hydrologic properties assigned to determine a design discharge.  The existing capacity of each culvert was analyzed and compared to the design discharge to identify conveyance deficiencies.  Structural deficiencies of the culvert and surrounding stream bed/banks were investigated and reported.

Based on the design discharge, and accounting for constraints of the surrounding topography, hydraulic analyses were performed to optimize a culvert design at each site.  A cost estimate was prepared for each site. A priority analysis was also performed to develop a phased replacement program for the Village.
