Title
Consider and take action on a resolution authorizing a professional services agreement with Lockwood, Andrews & Newnam, Inc. for design work related to the Oaks of Clear Creek Overland Flow and Acquisition Project (DR1902) in an amount not to exceed $249,976 (Director of Engineering)
Background:
Approval of this resolution will authorize the City Manager to enter into an agreement with LAN to design drainage improvements along Deer Ridge Drive in the Oaks of Clear Creek Subdivision for an amount not to exceed $249,976.

In August 2018, the final report was presented to City Council during a Council Work Session. One of the areas of concern discussed during the public meeting and again when presenting to Council was the drainage along Deer Ridge Drive where structural inundation can occur during 1% exceedance rainfall events.
Based on the H&H Study, City Staff created a potential drainage improvement project. This project was included as part of a list of potential drainage projects outlined on the City’s recently passed May 2019 General Obligation Bond Referendum.
For this contract, LAN will provide engineering services for drainage improvements specifically along Deer Ridge Drive within the Oaks of Clear Creek Subdivision. As noted in the previously prepared H&H Study, portions of the drainage system along Deer Ridge Drive were deemed inadequate. LAN would provide engineering services for 3 improvement options which are broken down as follows:
