Fax: [6511 704-9971 Bolton-Menk.com December 1,2016 Kristina Handt City Administrator 3800 Laverne Ave,N Lake Elmo,MN 55042 RE: Proposal for Slow No Wake Zone Assessments on Lakes Olson, De Montreville, Jane, and Elmo Dear Ms. Handt: According to your request,Bolton&Menk,Inc.has prepared the following scope of work and associated fees to address Slow No Wake Zone Assessments of Lakes that include Olson,De Montreville,Jane, and Elmo in Lake Elmo. With the exception of Lake Elmo, lake-wide no wake restrictions are triggered when the lakes reach a specific water surface elevation as determined by the Minnesota Department of Natural Resources(MnDNR).Typically,no wake restrictions are determined based on the likelihood of shoreline damage when the lakes are elevated due to flooding. Bolton&Menk's experience understanding shoreline impacts and erosion protection will support the City of Lake Elmo with objective information to make technical and informed decisions in establishing no wake elevations. Our successful approach includes: Unbiased Data —Establishing ordinances that affect lake activities are particularly difficult in communities that have emotional connections to their lake systems. In order to reduce perceived emotional impacts,impartial and objective data is required to establish no wake elevations that are not driven by passionate lake home owners or recreationists. Comprehensive Decisions —Lake regulations impact many users beyond those that live there. Therefore,the decisions that impact no wake limitations must include environmental implications, shoreline property values, and recreational uses. Public Education —The lake users must be informed as to why these elevations are established and what the potential impacts are if these limitations are exceeded in order to fully understand their water resources. Setting the elevation is only a portion of the overall goal; education tells the rest of the story. In continued service to the City of Lake Elmo,we are excited at the opportunity to analyze no wake elevations for several critical lakes. We are flexible in our scope and fees to best suit the City's needs. I will serve as your Project Manager and lead client contact on this project. Please feel free to contact me at 651-724-0404 or timol@bolton-menk.com if you have any questions regarding our proposal. Respectfully submitted, Bolton & Menk, Inc. Timothy J. Olson,P.E.,CFM Water Resources Project Manager Bolton&Menk is an equal opportunity employer.
