ADMINISTRATIVE COMMENTS:
Chapter 395 of the Texas Local Government Code requires municipalities to update their impact fees every five years. A best practice when performing this update is also to update the municipality's assumptions in land use, as well as master plans for both water and wastewater. The City of Lewisville recently updated its land use assumptions in 2023 with Freese and Nichols providing consulting services for that effort. Staff has also updated master plans for the whole water system, to include both the treatment and distribution systems and the wastewater treatment plant; all with HDR Engineering, Inc. An update to the wastewater collection system is required before the updated impact fee study can be completed. The last update for these studies was in 2018. With the entire system under one model, the City will be better prepared to address future needs with unified planning efforts under one consultant. This effort aligns with the Texas Commission on Environmental Quality’s “One Water” concept that recommends having an integrated approach to the management of water including the treatment and conveyance of water and wastewater as a single resource.
RECOMMENDATION:
That the City Council approve the award and authorize the City Manager, or her designee, to execute the agreement as set forth in the caption above.
