There will be some minor revisions to the parking lot and areas directly adjacent to the new building. This project complies with the following Site Plan Review Criteria SDC 5.17-125: A. The zoning is consistent with the Metro Plan diagram, and/or the applicable Refinement Plan diagram, Plan District map, and Conceptual Development Plan. Response: This proposed development is in the Community Commercial Zoning District and the sit-down restaurant use is a Permitted Use per Table in Section 3.2-310. B. Capacity requirements of public and private facilities, including, but not limited to, water and electricity; sanitary sewer and stormwater management facilities; and streets and traffic safety controls shall not be exceeded and the public improvements shall be available to serve the site at the time of development, unless otherwise provided for by this Code and other applicable regulations. The Public Works Director or a utility provider shall determine capacity issues. Response: AKS Engineering has analyzed the existing facilities and has determined they are adequate to serve the new development and the new development will not adversely affect the current public services. C. The proposed development shall comply with all applicable public and private design and construction standards contained in this Code and other applicable regulations. Response: The proposed development has been designed to meet all current applicable codes and regulations and typical construction standards. D. Parking areas and ingress-egress points have been designed to:facilitate vehicular traffic, bicycle and pedestrian safety to avoid congestion; provide connectivity within the development area and to adjacent residential areas, transit stops, neighborhood activity centers, and commercial, industrial and public areas; minimize driveways on arterial and collector streets as specified in this Code or other applicable regulations and comply with the ODOT access management standards for State highways. Response: The new development does not propose to alter the existing ingress-egress points, vehicular traffic patterns or connectivity to existing facilities. The proposal does include providing additional parking along the northern end of the parking lot. 6975 SW Sandburg Street •Suite 320•Portland,Oregon 97223 • T 503.352.4987 November 12,2012 Page 2 of 2 Buffalo Wild Wings Gateway Mall E.

Because your site meets the requirements of OAR 340-044-0018(2)(F),you do not need to prepare and implement a stormwater management plan, nor conduct annual monitoring, sampling and reporting,or submit a certification of non-exposure to toxics. If conditions at your facility change,such that it becomes a moderate or high environmental risk(e.g., installing new UICs; receiving high daily traffic of 1,000 or more trips; or using, handling or storing hazardous substances or toxic materials that arc exposed to stormwater),you must report to us immediately those changes so we can determine if additional requirements apply.

Proposed Stormwater Best Management Practices: Provide erosion control measures such as catch basin filter sack inserts and sediment fencing. -"(Area below this line tilled out by the Cs/v and Returned to the Applicant)- (At a mnanum,ion boxes checked by the City on the front and back of this sheet shall be submitted -for an;application to be complete for submittal although other requirements maybe necessary) Drainage Study Type (EDSPM Section 4.03.2): (Note,UH may be substituted for Rational Method) ❑ Small Site Study-(use Rational Method for calculations) ❑ Mid-Level Development Study-(use Unit llydrograph Method for calculations) ❑ Full Drainage Development Study-(use Unit Hydrograph Method for calculations) Environmental Considerations: 'A Wellhead Zone: -•-(, �� Q 'rrs Hillside Development: E Wetland/Riparian: kV Floodway/Floodplain: N /0 Va Soil Type: Sa L.4,A_ � � ® Other Jurisdictions: -`J /A Downstream Analysis: M N/A ❑ Flow line for st*ting water surface elevation: ❑ Design HGL to use for starting water surface elevation: ❑ Manhole/Junction to take analysis to: Return to Matt Stouder(Pp,City of Springfield,email: mstouderCci.springfield.or.us,FAX: (541)736-1021 Date Received: Revised 1/I/0S Molly Markarian NOV 1 3 2012 9 of 10 Original Submittal, • • II �..�y� Iregon Department of Environmental Quality go" Northwest Region V� 2020 SW 4th Ave,Suite 400 kV Portland,OR 97201-4987 John A.Kitzhabcr,MD,Governor (503)229-5263 FAX(503)229-6957 TTY 711 November 1,2012 Mr. Steve Becker,Operations Manager Gateway Mall LLC 3000 Gateway Street Springfield,Oregon 97477 RE: Approval for Authorization by Rule of Underground Injection Control(UIC) Systems UIC#: 14745 Site: Gateway Mall Location: 3000 Gateway Street, Springfield, Oregon 97477 Dear Mr. Becker: This approval letter,along with the accompanying notice of registration for authorization by rule,updates your site's UIC status to include a third drywell,based on registration information you submitted on 10/31/12. Because your site meets the requirements of OAR 340-044-0018(2)(F), you do not need to prepare and implement a stormwater management plan, nor conduct annual monitoring, sampling and reporting, or submit a certification of non-exposure to toxics. If conditions at your facility change,such that it becomes a moderate or high environmental risk(e.g., installing new UICs; receiving high daily traffic of 1,000 or more trips; or using, handling or storing hazardous substances or toxic materials that are exposed to stormwater),you must report to us immediately those changes so we can determine if additional requirements apply. If you have any questions about this letter you may call or e-mail me at(503) 229-6371 (cole.david n.deq.state.or.us).
