Box 2007 Oak Park Hei MN 55082-2007 Re: W.A.T.E. Enterprises, Inc. — Office/Wareho-Use & Cold Stora Buildin 5 610 Memorial Avenue North Concept Development Plan Review Our File No. 55-03-000 Dear Jud We have reviewed the latest concept development plan for the W.A.T.E. Enterprises, Inc, proposed office /warehouse and cold stora buildin at 5610 Memorial Avenue North as SUbi-vaitted b Fo1z, Freeman, Erickson, Inc. for W. Zintl, hic. and have the followin comments/recommendations: 1. The proposed improvements include constructin a retainin wall for the drivin area up 16' from the Wetland Boundar as shown on these plans. As the Cit of Oak Park Hei Wetland Conservation Act a we recommend a wetland delineation be prepared to accuratel define the existin wetland boundar and submitted for our review. Wetland boundaries t extend be the normal water level of a wetland. 2. Althou the Cit does not have a formal Wetland Ordinance in place definin re buffers and/or setbacks, we have been re these elements as part of PUDs or amendment =s to PUDs. The, Brown's Creek X.Vatershe..d District's + BCWD) en Emmons & Olivier Resources, Inc. (EOR), has indicated that since this "is not a DNR protected wetland Y) 9 the BCWD buffer re rules do not appl However, once a wetland delineation is submitted and reviewed, we will recommend minimum buffer and/or setback re to the Cit 3. The latest plan submittal has been revised as of 3/24/03 to increase the size of the future cold stora buildin We re draina calculations for our review. 4. Mark Doneux, previous BCWD Administrator, reviewed the previous plans on October 11, 2002. We offer the followiti con-ments on this previous review and BCWD Permit issued on 9/30/02: 0 Mr, Doneux indicates,, '7t appears that all storinwater facilities for the site, were desi approved and constructed cis part of the Kern Center Iniprovenlents in 1) 1999. 1 believe this was the intent when the Kern Center Improvements were 2335 West Hi 36 m St. Paul, MN 55113 in 6 1-636-4600 ■ Fax: 651-636-1311 constructed, however that assumed the 42" outlet to the Kem Center Pond would be opened and downstream improvements to the westerly wetland constructed for storm water retention. Since that time, the BCWD has not allowed improvements to the existing westerly wetland. As such, the existing Kem Center Pond and outlet has reached its limit for any further development in the Kern Center. As you know, the City of oak Park Heights and the BCWD are cooperatively pursuing a project to expand the Kern Center Pond to allow for further development within the Kern Center to meet BCWD's rules for rate and volume control. However, until such time the Kern Center Pond is expanded, the existing pond cannot handle storm water runoff from additional developed impervious areas. • Mr. Doneux utilized a 100 -year High .water Level (HWL) of 927.58 for the existing wetland. We have previously modeled this entire drainage area and are using a 100 - year HWL of 929.2. The applicant has revised his drawings to reflect the 929.2 level, and we suggest BCWD review the number they are using. A 1995 Washington County topographical map showed the water level of the pond to be 928.5, which is a good indication of the Normal Water Level (NWL) of the wetland. It appears that is the approximate NWL of the pond today, also. A BCWD Permit was issued on 9130102 with six conditions and one special condition that references five more recommendations from Mr. Doneux's 10111102 memo. The applicant indicated in his 317103 letter to the City that he has BCWD approval. It is my understanding from correspondence between Jay Johnson and Karen Kill, Washington Conservation District and BCWD Administrator, that neither party has signed the permit as of yet, and that she is verifying if any /all of the conditions of the permit have been met. 5. Driveway and parking area improvements are being proposed over the City's storm sewer easement for the existing 42" storm sewer along the north side of this parcel. verbiage should be included in the developer's agreement (or PUD amendment) indicating that the developer is responsible for restoring any of these surface improvements should repair or reconstruction of the existing storm sewer ever be required. 5. The nearest existing fire hydrant on this site is approximately 300' from the proposed cold storage building. The fire department should review these plans to verify if additional fire protection is required (we typically require hydrants with a 250' radius of buildings).
