The preliminary plat of "Golden Pond" is approved subject to the following conditions: a) The tree protection plan must be revised to indicate which trees will be saved, which trees will be removed for road and utility purposes, and which trees will be removed for building pads and driveways. A tree replacement plan, consistent with the requirements of the current zoning ordinance must be submitted. b) A landscaping plan for the required subdivision trees must be submitted. c) Revised plans addressing the following Grading Plan and Hydrology and Storm Sewer comments listed in the Engineering memorandum dated June 12, 2006, must be submitted and approved prior to issuance of a grading permit. 1) Grading easements will be required for the work outside the property lines. 2) Lot 3 Blk 4 is labeled incorrectly on the grading plan. www.cityofpriOl..Ii:ll<e.com Phone 952.447.4230 / Fax 952.447.4245 3) Show wetland buffer and buffer signs on the grading plan. 4) Slopes of maintained areas must not be greater than 4:1. Grading in backyard areas must be sloped greater than 2%. In flat areas, proposed grading should meet the minimum slope requirements in order to avoid low points which could be potential wet spots. 5) Grading for storm pond 1 is shown into the roadway, please revise. 6) Silt fence installation should be shown outside the grading limits. 7) Provide low floor elevations for lots adjacent to proposed park. Minimum low floor elevations for pads adjacent to ponds and wetlands shall be 2' above the 100-year HWL elevation 8) Numerous driveways will exceed the maximum 10% (ex. Lots 3-4 Blk 4), please verify and revise driveways. 9) All backyard drainage swales shall be contained within a drainage and utility easement. Provide easement for proposed swales on the grading plan. 10) The erosion control measures shall be installed and inspected prior to any site grading. All trees to be saved must be protected by silt fence or construction fencing around the drip line of the tree to protect the root system. This fencing must be installed prior to any grading on the site. Provide emergency contact person for erosion control on the project. 11) Provide access for water quality ponds. Pond access paths should be paved and have a maximum grade of 8% and be a minimum of 10' in width. The pond access paths should extend to the bench of the pond. 12) Provide spot elevations or grades for properties adjacent to the proposed project (lots on Maple Glen 2nd and Hickory Shores). Verify if the contours shown are proposed or as-built grades. 13) There are numerous areas where proposed contours do not tie into an existing contour correctly or is incomplete (ex. End of cul-de-sac), please revise. Minor adjustments of proposed contours should be made. Proposed contours appears to be directing water towards other homes, please revise to show drainage along the easements located on lot lines (example between lots 3 and 4 block 5). Flow arrows may be beneficial to show how the drainage will be conveyed. 14) Provide detail and label drainage swales on the grading plan. Do the swales have a special detail? Please revise swales to keep them under the maximum 300' length. The platting of easements for these swales should be revised to remove overlapping line work. 15) Provide riprap for all storm sewer outlets and show riprap locations on the grading plan. 16) Provide concept plan for property to the south and east. Sanitary and water service stubs may need to be provided for properties on the south side of Wedgewood Lane. 17) Sodded channels show up on wetland mitigation sheets and make hatch scheme confusing on that sheet. 18) Dikes used to create rate control ponds must at maximum use 4: 1 slopes and measure 10' wide at top. At minimum, a clay core should be designed in consideration of groundwater flow. If head difference between NWL of pond and downstream land exceeds 3', soils data will be required in the area and dike design must address maintenance of pond water level 1:\COUNCIL\RESOLUTI\PLANRES\2006\06-135 prelim plat Golden Pond. DOC and dike stability. Outlet pipes through engineered dikes should be designed with anti- seep collars. Specify that sand bedding not be used through dike section. 19) Pond skimmer structure inlet pipe to pond should be set approximately 1.5' below water surface, not at pond bottom. Storage under invert is used for sediment storage. The detail plan and profile views pipe sizes contradict each other. Please clarify. 20) Rock weeper detail should utilize larger open grade rock, to prevent scattering. Possibly 3"+. Weeper detail incorrectly reads "sweeper." 21) Minimum low floor elevations for pads adjacent to ponds and wetlands shall be 2' above the 100-year HWL elevation. The lowest opening shall be 2' above the emergency overflow. (This condition is not met on lots 4-6 blk 3, lot 1 blk 6, and lot 7, blk 5) 22) The wetland bypass outlet pipe flared end section should be placed at the wetland edge or additional easement is necessary from the flared end section to the wetland edge. 23) The design engineer is encouraged to call Prior Lake Water Resources Engineer, Ross Bintner at 952-447-9831 with questions on any hydrological and hydraulic comments. d) A revised preliminary plat showing lot dimensions and areas must be submitted prior to submittal of a final plat application. e) Revised plans addressing the Plat, General, Streets and Utilities issues below must be submitted and approved prior to submittal of a final plat application: 1) Additional easement is necessary for placement of the Maple Drive cul-de-sac. 2) Remove surface features from the preliminary plat. 3) Revise line work for the drainage and utility easement for swales.
