Once that time period has lapsed, if either political subdivision fails to do so, and the permit is regulated in the nature of that which is specified within the statute, the permit is deemed to be automatically granted. The City has received conunentary from Middle St. Croix Valley Water Management Organization and Brown's Creek regarding permits that have already been long since issued, and are well beyond the 120 day limit as extended by the City, for each applicant. Although those commentaries may be forwarded on to the applicant, and they may be certainly invited to respond or otherwise modify their plans to incorporate them, neither the City nor the Watershed Management Organization or District is in the position to force or impose those obligations on the applicant if, indeed, those comments are submitted beyond the regul If you have any questions, please feel f Paul A.

During this review, an additional concern was identified by the MSCWMO. MO. Specifcally, it was noted by the MSCWMO that Section 5 Grading and Drainage of the y Oak Park Heights zoning ordinance provides: "No land shall be developed and no use shall be permitted that results in •water runo causing flooding, erosion, or deposit of minerals on adjacent properties. Such runoff shall be properly channeled into a storm drain, water course, ponding area or other public facilities subject to the review and approval of the City Engineer." In the case of the Sigstad Carpet project, the proposed stormwater pond discharges onto private property with no improved drainage facilities. It is the concern of the MSCWMO that the increase frequency and duration of stormwater discharges onto this adjacent property could cause negative impacts and soil erosion. It is the desire of the MSCWMO that the City resolve this drainage concern prior to the construction of the Sigstad project. If you have any questions, please feel free to call me at 430 -6826.

This � '1'hx s project is for the coinmerciallretail development of a currently undeveloped property. As part of our p p pe � p ur review, a site visit was conducted. Since our agency has no direct approval authority over the project, our review being p .� � ev1 ew � s b e Ong made on behalf of the Middle St. Croix Watershed Management Organization. Based upon the conditions p site cond�t�ans observed and the proposed plans we would _offer the following continents: The site is 2.24 acres of which only that portion of 60 Street North on the 'property is impervious. . p p '' The project would have 1.21 acres (54 %) of impervious surfaces. Currently the northwester td site �d �" 13 of the site drains to the north and the southeastern 1.13 drains to the south. ale the and appears proposed p pp ors to meet the overall rate control requirements, other concerns are have been noted. The water leaving the site . g currently drains to the pond' at the southwest corner of Oakgreen -and Highway 36. The applicant is proposing pp p p Ong to collect and drain all of the site water to the south through a storrnwater pond. The following able summarizes umrnarizes the incremental changes in runoff from the pre and post development condition. jigstad's Carpet - Oak Park Heights Pre and Post Development Discharge Summary 2 Year Storm 10 Year Storm 100 Year Stoma 0.93 1.68 2.21 -0.64 cfs, -29% Mrs David Beaudet February 21, 2002 Page Two The first . major concern with this site is the apparent undersizing of the permanent pool volume (dead storage) for the pond. The permanent pool volume is that area below the outlet. Calculations provided by the applicant show that 14,520 cubic feet is required. Yet only 8,867 cubic feet are provided. We would recommend that the and b e sized to meet the requirements on site or an alternate plan b e implemented that provides the required pond �. permanent pool volume of 14,520 cubic feet. The other concern is the incremental change in runoff volume that is proposed to be discharged onto neighboring properties to the south. Based on observations at the site and the proposed plan, a few modifications of the proposed stormwater pond could minimize the incremental increases in stormwater runoff volume from this site. It is our recommendation that the live storage area of the pond (the area above the outlet) be oversized to mirdmi.ie discharges. The outlet control structure could be modified to further slow o &tfiow by placing a three inch PVC on the structure rather than the proposed four inch PVC. In situations of consecutive storms, discharge rates and volumes would be reduced if the three inch PVC was also ,placed at a lower elevation on the outlet control structure. 2) . Grading and Erosion Control Although the plan specifies that geotextile silt fence be installed around the perimeter of the project area, we would recommend that the contractor be prepared to install additional erosion control measures in the event that concentrated flow leaves the site. These measures may include the placement of an additional row of silt'. fence in low areas to minimize sediment from leaving the site. Silt fence along the project perimeter should remain in place until the site is restored and stabilized. Z hope that these comments will assist you with the review and comment on this .project.

Eckberg Of Counsel + uailed Neutral Arbitrator *Certified Real Estate Specialist +Qualified Neutral Mediator VIA FACSMI E & U. S. MAIL (651 ) 439-0574 A question has arisen relative to the authority of stormwater management within the City of Oak Park Heights in terms of which government entity has the current jurisdiction to determine stormwater flows, etc. within the community. Although there is an appeal pending with the Minnesota Court of Appeals relative to the orders of the Minnesota Board of Water and Soil Resources of January 24, 2001, the Board of Water and Soil Resources orders are, nonetheless, jurisdictional and effective until such time as they would be reversed by the Court of Appeals. Consequently, their order assigning the City of Oak Park Heights to Brown's Creek Watershed District for purposes of watershed authority is effective and does assign stormwater management issues to Brown's Creek Watershed District for purposes of authority at the present time. Obviously, that directive could change should the Court of Appeals issue its order in a manner so as to reverse that directive; however, until such time as that would occur the Board of Water and Soil Resources is the jurisdictional authority on stormwater management issues within the community.

The project site is located at the existing Routson Motors, in Section 33, Town 30 North, Range 20 West, City of Oak Park Heights. This project involves creating new parking lot and stormwater ponding facilities on existing Routson property. As part of our review we visited the site. The Washington SWCD CD has no direct regulatory authority over this project and our review is being made on behalf of the Middle St. Croix Watershed Management Organization. Based upon the site conditions observed and the proposed plans we would offer the following additional comments: 1) Storrnwater Management The project proposes to create approximately one acre of new parking lot (impervious surface) from existing vacant land (pervious surface). Water quantity and quality ponding is currently proposed along the eastern edge of this site. While the applicant appears to document adequate storage and rate control for the pond, we still have a concern for the off -site drainage going to the landlocked basin on the northeast end of the proposed pond. The City of Oak Park Heights must be prepared for the eventuality that runoff WILL occur from this pond during frozen ground conditions, back -to -back storms or after siltation has occurred in the pond sealing its bottom from infiltration. The as ■ licant should also document where off-site draina • e :oes and wh this will not cause erosion problems. Further, it should be determined when, how or if this off -site drainage will be connected into a public drainage system.

If a straw mulch is used for temporary p ry protection, it must be weed and seed free. In the event of concentrated flow leaving the site, we would g � d recommend that the contractor be prepared to place an additional row of silt fence in low areas to minimize sediment from leaving the site. Silt fence along the project perimeter should remain in place until the site is restored and stabilized. The specifications should require the mechanical anchorin g of straw mulch on the contour, however, most equipment can not operate safely on slopes steeper that 4 :1. Therefore, we recommend that all slopes steeper that 4:1 be covered with erosion control matting, such as a wood fiber blanket instead of straw mulch.
