Memorandum
Your approval is requested for a Professional Services Agreement with Hubbell, Roth & Clark, Inc. (HRC) in the amount of $1,000,000.00 for professional engineering services to complete a Citywide Drainage Analysis for Gravel Roads.
Over the past several years, city staff has received numerous complaints regarding drainage issues on gravel roads within the city of Ann Arbor. In many instances, these gravel roads were constructed prior to being annexed into the city and may not adhere to current city design standards. Over the years there have been numerous spot location attempts to address individual drainage complaints, but none that addressed stormwater management in a holistic and comprehensive manner.
The following table and map highlight specific areas that have been identified as regional and sub watershed areas to address for drainage analysis and recommendations to address drainage concerns and issues. It is anticipated that this project will be funded over 4 years, with each year focusing on an identified area.
