-204- T&G Land Inc. Page 4 of $ December 29, 2000 The storm sewer proposed along the western lot line of the proposed development could in the future be turned over to He City of Ramsey and should have the appropriate drainage and utility easements. The sizing of this pipe for potential use of draining neighboring developments, which will provide a regional benefit, shall be coordinated with the City of Ramsey. The use of RCP or PVC pipe would ensure a water and soil tight joint and should be used under pavement. Since the durability and age of the Corrugated Polyethylene Pipe is unproven, it is the recommendation of this City Engineer to. disallow the use of CPP for storm sewers that could potentially be turned over to the. City of Ramsey. . The east-west (CBMH 506 - CBMH 500 & STMH 406 - CBMH 400) laterals along with the catch basins that will drain the recycled aggregate surface (CBMH'200i & CBMH I00l) that are being proposed will be considered private utilities with maintenance to be provided for by the developer. Since the maintenance of the pond will be bore by the City of Ramsey, we expect that the sump manholes that are being proposed to drain the recycled bituminous surface are cleaned regularly. A performance specification to address long-term effectiveness of the proposed erosion control for the sumps and grading will be written as a condition of' approval. All storm sewer outlets shall have trashguards and Class III rip-rap installed according to City standard, details. Rip,rap shall be used for the emergency spillways and a detail should be submitted. Drainage patterns and impacts to neighbors to the east of the proposed metal building should be clarified. Access: The site will derive two access points from the westerly extension of 141~t Avenue and will be dedicated as a public street. Storm Water Management Fee: The Stormwater Management Fee will be waived for this site due to the City relocating T & O Land Inc. from its current location into Gateway North Industrial Park No. 5 to facilitate an industrial redevelopment project on Sunfish Lake Blvd. and McKinley Street. REU Number: The City has assigned the property a Residential Equivalent Unit (tLEU) number of 3.43. The quarterly drainage utility charge wilt be nine hundred seventy one and fifty'four cents ($971.54) (11.24 acres x $25.20/quarter). I I I I I I I I I I I I I I I I I I I
