The proposed project will consist of extending sanitary sewer, watermain, storm sewer and bituminous ' streets with concrete curb and gutter through the proposed Psyk's Fifth Addition development. The proposed project is located southwest and directl ad'acent Y J to the existing plat known as Psyk's Fourth Addition. The site is ' within the northeast and northwest quarters of the Southwest Quarter of Section 1, Township 120 North, Range 24 West within the city of Albertville, Wright County, Minnesota. See figure 1. ' Thore P. Meyer, Professional Engineer Robert Rohlin, Licensed Land Surveyor ' SANITARY SEWER The City of Albertville recently installed a 12-inch PVC sanitary sewer along the proposed roads known as Lachman Avenue Northeast ' and 53rd Street Northeast and then south within the dedicated park right-of-way to the south edge of the plat. See attachment 2. Four-inch sanitary sewer service risers v~~ere installed from the existing 12-inch sanitary sewer, adjacent to the lots of the proposed Psyk's Fifth Addition. These existing service leads will have to be extended to a point ten feet beyond the right-of-way ' line. In addition, there are six lots which will need extension of services to them. These a re lots 1 and 2 , block 1; lots 1 and 2 , block 2; lot 1, block 4; and lot 5, block 5. When the original 12-inch sanitary sewer was installed, a permit ' was received from the Minnesota Pollution Control Agency for the installation of services. The six services that have not been installed will need to have a new permit extension granted by the Minnesota Pollution Control Agency. Up to this point in time, the ' city of Albertville is currently under a moratorium of sewer extensions until such time as the wastewater treatment facility is expanded. Recent action by the City Council of Albertville is ' making this possible. It is, however, a possibility that the Minnesota Pollution Control Agency may not allow hook-up to the ' six services until the wastewater treatment facility is construc- ted and in operation. Eight-inch sanitar y sewer will be extended from 53rd Street ' Northeast, north along Lambert Avenue Northeast. In addition, 8-inch sanitary sewer will be extended east and west from the existing 12-inch along 53rd Street Northeast to approximately 10 ' feet beyond the plat boundary to allow for future extension of the sanitary sewer services east and west without the need for disrupting the existing city street. ' All sanitary sewer costs will be 100% assessable to the developer. ~ ,_ WATERMAIN The watermain would consist of the extension of the existing 6-inch watermain along Lambert Avenue Northeast, from 54th Street ' Northeast to 53rd Street Northeast. The watermain on 53rd Street Northeast and Lachman Avenue Northeast shall be 8-inch in size. ' One-inch copper water services will be extended to ten feet beyond the right-of-way line for each lot. The watermain will be extended ' approximately 10 feet beyond the proposed plat boundary on the east and west ends of 53rd Street Northeast and at the north end of Lachman Avenue Northeast. Hyarants will be installed on the east and west ends of 53rd Street Northeast to allow for flushing of the watermains for the time being. It should be noted that ' these hydrants will need to be relocated in the. future as the watermain is extended east and west. There will be approximately a 61-foot watermain stub at the north end of Lachman Avenue Northeast which will not have a hydrant at the end of the line. No services will be installed on this line. The hydrant spacing which currently is proposed is at the maximum allowed by the Joint Powers Water Board and, being that no services would be installed on this stub, we do not feel that a ' flushing hydrant is necessary at the end of the roadway. See figure 2. All watermain costs will be 100% assessable to the developer. i n C i~ STORM DRAINAGE All storm drainage within Psyk's Fifth Addition will be handled by surface water drainage, utilizing the proposed streets and side and rear lot lines as conveyance systems to the collection points. The collection points will utilize reinforced concrete pipe storm sewer from 12-inch to 24-inch in size to allow for conveyance of the water to the Minnesota Department of Natural Resources -3- ' Protected Wetland No. 86-414W located on the south side of the proposed Psyk's Fifth Addition. The storm drainage system will ' provide an overflow from the no th t f ' existing lowland located at the r wes corner o Psyk s Fifth Addition. See figure 3. The development of the road known as Lachman Avenue Northeast will result in the destruction of a wetland of approximately 0.33 acres ' in size. Pursuant to the Wetland Mitigation Plan which was approved by the City Council at their August 3, 1992 meeting, the ' developer will expand the existing lowland northwest of the proposed plat as mitigation for the destruction of this wetland. ' In addition, the Minnesota Department of Natural Resources is requiring that a sedimentation pond be constructed at the outlet ' fo r the proposed storm sewer located in lot 1, block 5 of the development. The sedimentation pond's purpose is to provide for ' water quality improvement prior to entering the DNR-protected wetland. ' All storm sewer costs will be 100% assessable to the develo er. P ' STREET The street improvements would consist of a three-inch bituminous pavement and surmountable concrete curb and gutter placed over a ' 12-inch gravel base. See figure 3. The boulevard area will be restored by the placement of 4 inches of topsoil to about 10 feet behind the right-of-way line. A 4-foot ' strip of sod will be installed next to the curb for erosion protection. The construction of the streets will be 100% assessable to the devel ope r. ~ ~_ 0 u EASEMENTS In order to construct the sanitary sewer, watermain, storm sewer ' and street within this development, it will be necessary for easements to be obtained for their installation. These will be predominantly at the east and west ends of 53rd Street Northeast and at the north end of Lachman Avenue Northeast. In addition, pe rpetual easements will be required adjacent to lot 1, block 3 ' fo r the storm sewer improvements and also for the sedimentation pond to be located south of block 5. Obtaining these easements should not be a problem since all the property in question is owned by the developer for Psyk's Fifth Addition.
