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