These pipes must be extended or storm sewer provided. The same requirements as grading along Armstrong and the railroad tracks apply.

The placement and application of these products is not specified on the plans. A conditional use permit is required to import more than 400 c.y. of material. Mass grading tolerances shall be =t:0.5ft in right of way and drainage and utility easements. The tolerance on all building pads in outlot~ shall be ±1 ;0 ft. These tolerances are valid only for mass grading activities identified in the development agreement. " Catch basins need to be provided for the low points in Bunker Lake Boulevard. Several low areas in parcels do not have storm drainage shown. The final plans for each parcel must provide drainage for these low areas. Several of the cul-de-sacs on the north side of the site are shown close to the property line and may require grading off the site to properly match grades. Grading Outside the property lines is not permitted with out written permission from adjacent landowner(s) being submitted to the city. Infiltration is a vital element of the stormwater management plan. Infiltration areas should be left in as undisturbed condition as possible during grading. Grading is shown outside the silt fence in the county right of way. Grading in the ROW requires a county permit and modification of the actual road embankment is generally not permitted except for adding new lanes. Silt fence is shown as being installed as short segments on several of the plan sheets. Silt fence shall be installed in a continuous manner down slope of all disturbed areas. Silt fence shall be located so as to not interfere with subsequent construction such as pipe installation. All pond outlet structures shall be concrete skimmer structures per city plans. Existing wetlands on the site will be filled and new mitigation areas will be created as part of the construction of this project. Permits are required for disturbing or enlarging wetlands. These permits must be in place prior to commencing any work around the wetlands. The mitigation areas shall be constructed as a first priority prior to filling the existing wetlands. The new mitigation areas shall be connected by temporary pipes or swales so that they receive water prior to installation of the storm sewer. The mitigation areas must be protected during construction on the rest of the site. Grading must be shown for Park-n-Ride site and for Well house No. 3. Last printed September 15, 2003
