Review Letter: Sunfish Estates February 20~ 1996 Page 2 o 3 6. TranSportation Impacts: On November 20, 1995, the Ramsey City Council approved the establishment of a Transportation Impact Fee. If it is enacted by April 15, 1996, the plat will ~ subject to said fee at a rate not to exceed $500.00 per lot. 7. Stree.B: There is one cul-de-sac in the plat and it does not exceed the 600 foot maximum length, restriction. 8. Tree Preservation and Planting Plan: The preliminary grading plan identifies significant oaks.[ The plan should also show the general limits of tree cover. The oaks identified on the stireet surfaces are assumed to be lost. Other significant trees to be preserved should denote the means of preservation and which trees are intended to remain. (It should be note~ that the City's tree conservation policy references builders using tree save fences. If effective tree conservation occurs for the front yard of lots, those lots can be exempted from [he establishment of one 2-inch diameter tree.) 9. ~ The area of the plat is of rolling topography with several small pocket wetlands. Sunf~h Lake is located on the western boundary. A grading and drainage plan has been prepared by Derrick Passe, P.E., and is dated February 1, 1996. This plan has been reviewed and is generally acceptable. Except for less than a hundred feet of 146th Avenue, all paved surfaces within the plat are conv{yed overland to a storm sewer in Sunfish Lake Drive. This storm sewer conveys flow from north to south and discharges to a sedimentation pond created on the southeast corne~ of Lot 14. It would be easier to facilitate future cleaning of this pond if it had better accesO than in a rear yard of a private residence. It is staffs recommendation that the storm pipe c[ischarge to the existing wetland on Lots 16 and 17. Sediment cleaning could then be overflow from the south end of this wetland accomplished from Sunwood Drive. An pipe couldldischarge~faq to Sunfish Lake. It sh(~uld also be noted that 345 square feet of wetland is proposed to be filled to acco ,mmodate a house pad for Lot 17. A deminimus exemption from the Wetland Conservation Act is applicable, but must be requested from the Lower Rum River Water Management Organization. Although this amount of area may be filled without repla .qement, it would be staffs recommendation that this wetland be enlarged to as great a degree as development will allow. Expansion opportunities appear to be available on the north,!east and south sides of this wetland. Utilities: It is Staffs understanding that the site improvements will be installed as a private pmjed.'t with no financial participation on the part of the City. Sewer and water utilities are available to the site. The construction of Sunwood Drive will extend the watermains along the eastern boundary of the site. 10.
