We understand the City has coordinated with the original paver supply company and has <br /> negotiated replacement of the deteriorating pavers in the alleyway with a permeable pavement system. <br /> While grades along the alley corridor are relatively steep, we believe that we can design a system that: <br /> 1) Captures stormwater runoff on grade to reduce the total volume and flow rate at the end of the street. <br /> 2) Filters and stores polluted stormwater runoff promoting an increase in water quality entering the river. <br /> 3) Utilizes the flatter grades at the south end of the alley to filter and treat stormwater runoff from a highly <br /> impervious watershed. <br /> This proposal defines our scope of work and associated fees in a task oriented format. The scope includes <br /> analyses of the watershed and the applicability of a stormwater treatment system, design plans and specifications, <br /> and project management to ensure a collaborative effort with the City and that project milestones are met. If this <br /> proposal is acceptable and you wish to proceed, we will begin work immediately. <br /> Please feel free to contact me if you have any questions or if you require any additional information. <br /> Sincerely, <br /> BOLTON&MENK, INC. <br /> Cody Holmes,PE <br /> Project Manager <br /> Enclosures: Scope of Services <br /> Estimated Hours and Fees <br />
