Purpose

Allow LRE Director to enter into an amended contract with Ayes for the Hemlock Dam project.

Background

Background: The Hemlock Dam creates Hemlock Slough, located at Hemlock County Park, in the Township of LaValle, Sauk County and was constructed in 1964 for recreational purposes. During the months of August and September 2018, the dam sustained damages during a flooding event. Subsequently, the Wisconsin Department of Natural Resources (WDNR), gave the Sauk County Land Resources and Environment Department an Administrative Order to Repair or Abandon Hemlock Dam.

 

On October 15, 2019, the decision was made by the Sauk County Board of Supervisors to repair Hemlock Dam. Proposals were solicited for the design, engineering, and grant administration services; which were reviewed and scored against the criteria noted within the RFP.  The most advantageous proposal received was from Ayres Associates in the amount of $38,041.00.  On December 17, 2019, the Sauk County Board authorized LRE staff to enter into a contract for engineering services.

 

Ayres Associates worked with DNR staff to prepare complete and final plans for the replacement of Hemlock Dam.  However, the County was made aware of increased estimated costs for the replacement and for future ongoing maintenance for this dam.  As a result, the County is pursuing reconstruction of the dam to that of a smaller structure so that additional jurisdictional requirements proposed by the WDNR for large scale dams can be avoided.  The contract with Ayres and Associates would need to be amended to accommodate this new proposal.  The lump sum total estimate would increase to $76,191.
