FAX: 952.881.0023 July 6, 2004 Mr. David Osberg Administrator City of Hastings 10 1 4th Street East Hastings, MN 55033-1955 Re: Proposal for Consulting Engineering Services Related to a City Dock Dear Mr. Osberg: Thank you for contacting us regarding engineering services related to establishing a City dock on the Mississippi River adjacent to the downtown area of Hastings. We look forward to the opportunity to work with you. This proposal is based on previous communication with Mark Frazer, the meeting with you on June 9th, the December 10, 2003 Hastings Public Dock Proposal, the March 19,2004 Corps of Engineers (COE) permit application by the City, our past work with flow modeling in this area, and a recent site visit. The following information outlines a proposed scope of work for your review. The selected site appears appropriate for a dock based on our recent site visit (see attached photo). We would like to meet with a City representative(s) to discuss the exact location for the dock and connection with existing walkways and park system. We have some bathymetry (water depths) in this area from the two dimensional flow model we completed for the COE. During this visit we would also verify water depths in the area selected for the dock.. Flow velocities in this area will not be a significant concern during normal flows. The erosion around the base of the cottonwood trees near the boat launch is evidence of high flow velocities during flood flows (see attached photo). These flow velocities will need to be considered in the design of the dock anchoring system. The erosion around the existing cottonwood trees may be a maintenance consideration for City park staff. The scope of work may be separated into two phases. The first phase includes a feasibility study, preliminary design, and permitting. The second includes final design, preparing bid documents, assistance with obtaining bids, and construction administration. At the present time, part of Phase I has been completed with the Hastings Public Dock Proposal and the COE permit application. We propose starting our involvement with a site visit with City staff, determining the status of the COE permit application, and moving it forward. This will include discussion with Joe Vanta and possibly providing addition information such as engineered dock plans. For the purposes of this proposal we 7~j/A/
