The document summarizes a city council meeting to discuss a drainage master plan. It provides background on two previous studies from 1986 and 1993 that identified drainage issues. The drainage master plan will update drainage plans, identify problems and solutions, prioritize capital improvements, and include analysis of 39 miles of drainage infrastructure across 5 watersheds. The council is recommended to approve a contract with Freese and Nichols, Inc. for $482,032 to complete the drainage master plan.

1. City Council Meeting
June 28, 2012

2. Project Background
 1986 – Walton & Associates completed the
Stormwater Management Plan
 Provided an overview of drainage issues and identified
needs
 Drainage design standards, stormwater management
ordinance, and stormwater management program
 1993 – David Griffith & Associates completed the
Drainage Utility Feasibility Study
 Included a drainage analysis report by Freese & Nichols
based on data from the 1986 study
 Recommended drainage improvements

3. Scope of Work
 The Drainage Master Plan will serve as a tool to develop
an updated Drainage Capital Improvements Plan to
support the City’s projected needs and future growth.
 It will identify and prioritize drainage and flooding
problems and provide potential solutions and cost
estimates.
 The project includes 5 areas of study:
 Hydrologic analysis
 Hydraulic analysis
 Review of existing watershed studies and existing conditions
 CIP development
 Geomorphological assessment of Wolf Pen Creek

4. Scope of Work
 The scope of work will also include:
 Data collection and field surveying
 Evaluation of existing models and creation of new
models
 Review of existing flood concerns
 Identification and ranking of possible alternatives
 Compilation of results into a geodatabase
 Drainage infrastructure to be analyzed and
evaluated:
 Approximately 39 total miles
○ 25 miles of new stream models created
○ 14 miles of updated models
