Title
Consider a resolution authorizing the Mayor to execute a Contract for Engineering Services with Lockwood, Andrews & Newnam, Inc. for the Oak Bluff/Greenfield Drainage Improvements Project.
Body
The City experienced right-of-way and private property flooding in the Oak Bluff Estates neighborhood in 2013 and 2015. Therefore, in July of 2015 at a cost of $44,600, the City retained Lockwood, Andrews & Newnam, Inc. (LAN) to perform detailed analyses and to identify potential measures, and their estimated costs, that could be implemented to reduce flooding frequency.
The abutting Greenfield neighborhood that is located outside the corporate limits of Round Rock had also experienced similar flooding issues and the City has been in conversation with both the residents of Greenfield and Williamson County. In December 2015, City staff met with Williamson County staff, and the general consensus during the meeting was that it would be prudent for the City and the County to partner together to determine potential improvement alternatives that would benefit both neighborhoods; and then to obtain design documents for a selected alternative. Subsequently, the City drafted an Interlocal Agreement (ILA) with the County that is under consideration by the Council as a separate agenda item.
This contract will provide refined analyses focused on both neighborhoods, will identify potential alternatives that could be implemented to reduce flooding frequency for the benefit of both neighborhoods, and will provide engineering design and technical documents necessary for construction of the aforementioned selected alternative.
Cost: $80,295
Source of Funds: 2014 Drainage Revenue Bonds
