Preliminary. Plat Review: Ramsey Town Center 2~'~ Addition January 30, 2004 Page 4 of 6 to discharge into the stormwater system. The open spaces to the east comprise of two green connections. The northern open space will contain a trail with pavers, landscaping, and benches. The southern open space ,,viii serve mostly as a trail corridor. Access and Streets: The development will receive access from the public streets of Peridot St. NW, East Ramsey Parkway, and Olivine St. NW. It should be noted that there will be no direct access to Ramsey Blvd. into this development. Grading and Drainage: The grading and drainage plan was reviewed and generally conlbrms to city standards. Rems remaining to be addressed include submittal of a table specifying house type, garage elevation, minimum floor elevation and street grade. Further information regarding the drainage calculations is needed to show' how the run-off from this development fits with the model developed for entire Ramsey Town Center project. Specifically the calculations must demonstrate that this development does not exceed the anticipated runoff Iht this parcel. These plans should be submitted to the Lower Rum River Watershed Management Organization (LRRWMO) tbr a permit. Calculations do not need to be submitted to the LRRWMO but the submittal should reference the master calculations and the drainage structures impacted. Easements/Utilities: The utilities in the public streets are definitely public. Public utilities in blocks 35 & 47 must be protected by proper drainage and utility easements to allow future maintenance by cit7 crews. The domestic water services are shown as 1 ½". They should be changed to 1". Preliminm2/ reviexv of the water services ~br the buildings on lots 44, 45 and 46 indicates that the fire services shou[d be 6". One set o~' water services between lots 45 and 46 should be moved to the north end of lot 46. If there were a fire in both buildings, the 6" line supplying both services would not supply adequate pressure. There are several math errors in the elevations shown on the plan and profile sheets for sewer and storm sewer. The master storm water plan adopted for Ramsey Town Center indicated that some storm water treatment would be provided on each site. Open space ibr storm water pre-treatment is shown the portion or' the project west of Olivine Street. No storm water ponding is shown east of Olivine street where the bulk of the hard surfh, ce areas are. Tree Preservation. A tree preservation plan was approved at the final plat stage of the Ramsev Town Center Addition. ,ks a result of that plan, several areas were identified as tree save areas in conjunction with the initial mass grading oF the site. The City will need to review and approve a revised tree inventory of the trees remaining on this specific development parcel as well as a revised tree preservation ?lan prior to final approval of the development.
