​The City of Ann Arbor is designing and constructing a retrofit of stormwater features for First Sister Lake. Features will include water quality improvements, conveyance modifications, and ecological habitat improvements. This project will have a significant amount of public engagement with the neighborhood and the local community.

After putting out a request for proposal in June 2016, the city has contracted with Environmental Consulting & Technology, Inc. (ECT) to conduct engineering design services for the Sister Lakes Stormwater Retrofit. ECT's work will include historic document review, survey, preliminary design, final design, construction documents, and bid specifications.
