Northwest Associated Consultants From: Leon Opatz, P.E. Re: Response to Planning Report (dated April 5, 2001, File No. 798.02- 01.01) Rainbow Fuel Station, Oak Park Heights, MN Conditional Use Permit /Planned Unit Development Amendment /Sign Variance RLK - Kuusisto, Ltd. Project No. 2001 - 256 -M /Phase 13 RLK- Kuusisto. Ltd. appreciates the support and assistance provided by City staff and consultants regarding the above referenced project. We are pleased to offer the following comments to the conclusion/recommendation section of the above referenced planning report from Northwest Associated Consultants. The numbers correspond to the conditions as listed in the report. The condition has been restated in Italics for easy reference. 1. Both the catch basins and the existing stormwater pond shall be improved to prevent and treat fuel spillage prior to their entrance into the City's system. The drainage plans shall be subject to the review and approval of the City Engineer. RLK - Kuusisto, Ltd. proposes a Stormceptor system to collect and filter site drainage before discharging into the existing storm sewer. Because the Stormceptor will prevent any gasoline or oil from entering the pond, modifications to the pond will not be necessary. RLK has discussed the proposed storm system with the City Engineer and he concurs with our proposal.

RLK is working with the City's consulting engineer to address any site access issues there may be. We understand the City's consulting engineer is currently reviewing site access and will address this issue in his report. 3. The landscape plan shall be subject to final review and approval by the City Arborist. The City Arborist has commented on the location of the proposed trees. RLK - Kuusisto, Ltd. has revised the landscape plan to be consistent with the Arborist's direction, and will present the revised plan at Thursday's Planning Commission meeting. The landscape material will be consistent with the existing site landscaping. 4. Prior to installation of the proposed signs, the applicant must receive approval of a variance for the number of signs requested. The proposed fuel center canopy will have four Rainbow logo displays (each 7'10 x 2') and two scrolling gasoline price signs (approximately 7' -10" x 2'). The total sign area will not exceed the maximum allowable area per Code of 150 square feet. S. The applicant shall submit and receive approval of detailed lighting and photometric plan that demonstrates that the lights from the proposed canopy are in conformance with the outdoor lighting standards outlined in Section 401.15.B. 7 of the Zoning Ordinance. A site - specific photometric plan will be submitted to the City from the owner's electrical consultant. Rainbow Foods is committed to incorporating a lighting /photometric plan that is consistent with the City's zoning requirements. 6. The applicant shall submit color renderings and material samples that demonstrate the kiosk will comply with the design guideline's standards. The architectural material for the kiosk will be consistent with the existing building facade and consistent with the City's design standards. A detail elevation identifying material type and color will be submitted upon building permit application.

The City Engineer shall approve the design of the pump islands. RLK is working with City staff to verify an acceptable pump island design. The City Engineer will address this issue in his report. 8. Use of an outdoor speak system is prohibited. The proposed fuel center will not use an outdoor speaker system. 9. Should the applicant request an outdoor storage area, they must apply for and receive approval of an additional conditional use permit under Section 401.30. E.5 of this Ordinance. The applicant does not require outdoor storage as part of the fuel center request. 10. The fuel service center- must have an attendant on duty during all hours of operation. It is Rainbow's desire to provide 24 -hour fuel service. During non -peak store hours (11:00 p.m. -6:00 a.m.), the fuel center will be unattended and patrons will be able to refuel by paying at the pump (i.e. credit card). To ensure a safe and secure environment. the fuel center will be equipped with closed- circuit television and patrons still be limited to 30 gallons of fuel per transaction. Additionally, the fuel center will provide a centrally located emergency shut -off and a direct dial phone to the store. Furthermore, during non - attended hours, Rainbow staff from the main store will be available to assist customers with fueling concerns and to handle fuel center maintenance and security issues. Rainbow Food representatives will be available to address this concern in further detail. 11. The applicant shall designate an off - street loading area in conformance with Section 401.15.F.12 of the City Code or schedule all gas deliveries during off -peak hours. Enclosed please find an exhibit identifying turning movements for a refueling truck. Refueling will be limited to off -peak hours whenever possible.

The owners of the site property (Lot 2, Block 1, Oak Park Ponds Addition) shall agree to future private roadway access from the northeast corner of the property to the property directly to the east (Outlot A, Brackey 2" Addition). RLK has met with the adjacent property owners regarding a future private roadway access. The adjacent property owner and Rainbow Foods are in agreement that the construction of a private roadway will occur sometime in the future. Rainbow Foods will be present to address this matter at the Planning Commission meeting. The adjacent property owner has been invited to attend the Planning Commission meeting as well. 13. The applicant shall demonstrate that the site has adequate trash storage. This area should be inside the proposed building or in a trash enclosure that is constructed of the same material as the building. The fuel center will not have an independent trash receptacle. Individual windshield service facilities will be available for fuel center customers. Furthermore, a trash receptacle will be located in the kiosk. Maintenance and collection of fuel center trash will be conducted by Rainbow Food employees, and placed in existing Rainbow Food trash receptacles. Please accept our comments and enclosures as the applicant's response to the Oak Park Heights Planning Report. Rainbow Foods appreciates the comments provided by City staff and is willing to comply with City requirements for the proposed fuel center. Please contact our office with questions or if additional information is required. Enclosures (Corresponding Condition No.): I. Stormceptor System Information II.

Stormceptor j SterrnCePtO . iL COMBATS POLLUTION Stormceptor is a pollution pre■ention device that efficiently removes oil and sediment from stormwater. and stores them for safe and easy removal. Stormceptor is unique in the market because it will not release trapped pollutants between servicing, even in periods of peak water flow. Designed to replace more costly conventional water quality inlets, and tested in laboratory and field applicat ions. Stormceptor offers other benefits beyond front -line pollution control. LOWERS COSTS When installed in new or existing storm sewers, Stormceptor eliminates the need for catch basin sediment traps, and reduces the frequency of scheduled sewer flushing. .Stormceptor is - — - available in models _ designed for private and — _ — public usage. ^ t -- , r � 7„ Stormceptor can be used in a treatment train approach upstream of ponds, wet- . lands, sand filters and infil- tration systems to extend N _ :•.` the maintenance interval of these systems, prevent groundwater contamination, and ensure fast, efficient dean up of accidental spills. iiirk ow Localized containment eases both the identifica- tion of polluters, and the transfer of cleanup liability to them, instead of the municipality.
