<br />H:\ORNO\2019 New Projects\Fee Estimate - 2019 Pond Assessments.docx <br /> <br />January 22, 2019 <br /> <br /> <br />City of Orono <br />Attn: Adam Edwards <br />P.O. Box 66 <br />Orono, MN 55232 <br /> <br />RE: 2019 Stormwater Pond Assessment <br /> <br />Dear Adam: <br /> <br />As requested, we have prepared a scope of services and fee estimate for completing the 2019 Stormwater <br />Pond Assessment for the City. Based on our understanding of the project, we propose the following <br />scope of work: <br /> <br />Stormwater Pond Assessment – Browns Bay (BB), Carman Bay (CB), Crystal Bay (CY), Hadley Lake <br />(HA), Lafayette Bay (LF), Mooney Lake (MO), Peavey Lake (PL), and Smith Bay (SM) Subwatersheds <br />• Coordinate and meet with City as necessary to review and discuss Pond Assessment procedures <br />and results. <br />• Establish location of all stormwater ponds within subwatersheds on City Parcel Maps through <br />review of City Maps, Record Drawings, and visual inspection. <br />• Establish pond ownership and maintenance responsibility for all stormwater ponds within the <br />listed subwatersheds. <br />• Establish location of City maintained stormwater ponds within subwatersheds with GIS <br />coordinates. <br />• Delineate watersheds for City maintained stormwater ponds. <br />• Define watershed characteristics for City maintained stormwater ponds. Characteristics shall <br />include impervious surface percentage, time of concentrations, areas, and soil types. <br />• Define pond characteristics for City maintained stormwater ponds. Characteristics shall include <br />design permanent volume, estimated existing permanent volume, outlet design, normal water <br />level, and high water level and record to Cartegraph and/or GIS database. <br />• Define drainage flow direction for all stormwater ponds within the listed subwatersheds. <br />• Prepare initial rating of City maintained stormwater ponds within subwatersheds as defined in <br />City’s Pond Assessment Program. <br />• Prepare recommendations for pond bathymetric surveys to establish accurate existing permanent <br />volumes based on initial ratings and discussions with City. <br />• Provide layer on City’s GIS mapping for data generated from pond assessments. <br /> <br /> <br />Assumptions <br />• No Maps or Plans will be generated as part of this proposal. <br />• No surveys will be performed as part of this proposal.
