Please refer to the Springfield Fee Schedule for the Pre-Submittal Application fee. The submittal package must conform to the application completeness checklist attached to this form. You are required to submit Nine (9) copies of the submittal requirements packet for pre-submittal review. Pre-submittal meetings will be conducted every Tuesday and Friday between 10:00 am and noon. We will strive to conduct the Pre-Submittal meeting within five to seven working days of receiving the application. 2. Applicant and the City conduct the Pre-Submittal Meeting We strongly encourage you, the owner and design team to attend the Pre-Submittal meeting. The meeting will be held with representatives from Public Works Engineering and Transportation, Community Services (Building), Fire Marshall's office, and the Planning Division. The meeting will be scheduled for 30 to 60 minutes. The Planner will provide you with a Pre-Submittal Checklist at the end of the meeting specifying the items required to make the application complete-if it isn't already complete. You will then have 180 days to make the application complete for submittal and acceptance by the City. 3. Applicant Submits a Complete Application When you have addressed all of the items on the Pre-Submittal Checklist, please submit 18 copies of the complete application to the City. A fee will be collected at that time and the 120 day calendar review period will begin. When the Planner has prepared a draft land use decision, the draft will be mailed/faxed to the applicant/owner/design team for their review. At the applicant's request, the planner will schedule a meeting to review the draft with appropriate staff if certain issues need resolution before the final land use decision is issued. Owner's Signature This application will be used for both the required Pre-Submittal Meeting and subsequent complete application submittal. Owner's signatures are required at both stages in the application process. An application without the Owner's signature will not be accepted.

OVERVIEW 1.0 INTRODUCTION The subject property involved in the proposed development is a gently sloping 0.54-acre development site, currently undeveloped. The site is on Tax Lot 1100 Assessor's Map 17-03-15- 33. The site is bounded on the North by Game Farm Road, and is bounded on the South, East, and West by adjacent lots (near Gateway Street). A 200 square foot coffee kiosk is proposed on the subject property, complete with 2 drive aisle, sanitary sewers, and storm drainage infrastructure to carry runoff from the development to the existing public storm system. 4,128 square feet of new or replaced non building surface will be added to site. All of the new non-building runoff will be treated with a vegetated swale. Stormwater runoff from the paved area on the site will be directed through a curb cut to the vegetated swale. Catch basins will be placed in the swale for catching overflow. Roof and sidewalk run-off is routed to the existing system on the site. The vegetated swale will filter pollutants and sediments from the run-off and the planting of trees within the swale and detention pond areas will further pre-treat the stormwater runoff by reducing the temperature of the runoff before it enters the public system. Hydrologic calculations to determine the existing (pre-development) and proposed (post- development) runoff amounts are included, as are hydraulic calculations to determine pipe sizing, and calculations to determine the sizing of the proposed vegetated swale. A "Stormwater Management System Scope of Work" sheet was submitted to the City for the proposed development. The scoping sheet states that a downstream analysis of the receiving system is not required for this report. Small Site Study is required using the Rational Method for runoff. 2.0 PURPOSE The purpose of this report is to attempt to comply with the requirements of Article 32.110 Stormwater Management of the Springfield Development Code, and the Springfield Public Works Engineering Design Standards and Procedures, dated April 2006. PRE-SUBMITTAL REC'O .,;"'" \ 2""--'2-\:-07 . . HYDROLOGIC AND HYDRAULIC CALCULATIONS DARI MART ADDITION: 1.0 PURPOSE The purpose of these hydrologic and hydraulic calculations is to determine the runoff flows from the subject property for both pre-development and post-development conditions, and to verify pipe and swale sizing for the proposed development. 2.0 CALCULATION METHODS The Rational Method was used to determine the post-development runoff from the site. Excel software was used to perform the specific calculations. The input variables and resulting flow rates are included in Appendix A. The flow calculated from the Rational Method was used to size the drainage pipes for the post-development runoff from the site (25-year event). Time of Concentration: The Time of Concentration for the pre-development conditions was determined using an initial time of 10 minutes. The pipe flow calculations were determined using Manning's Equation for pipe flow. 3.0 PIPE SIZING The pipe sizing calculations is included in Appendix A. Required flows to the swale and the existing 8-inch stormwater pipe were proportioned from the site peak-flow calculation and areas being drained. A Manning's n value of n = 0.013 was used for PVC pipes per City of Springfield Engineering Design Standards manual, achieving a minimum cleansing velocity 3.0 ft/s for all new pipes. 4.0 SW ALE/CONVEYANCE A vegetated swale was chosen as the best method for pre-treating the stormwater runoff by allowing for natural percolation. The vegetation will also aid in cooling the water prior to disposal in the public system. Swale design guidelines were obtained from the Bureau of Environmental Services-City of Portland (BES) manual. A detail from the BES manual is included in Appendix B, while the specific dimensions and layout of the swale design is shown on the Grading Plan, Sheet C2. Form SIM from the BES manual was used to calculate the necessary swale dimensions for the post-development runoff. Tree credits were taken as applicable from the landscape architect's plans. The Form SIM is included as Appendix B. The required swale size was calculated to be 372 square feet. The site provides 972 square feet of swale. PRE.SUBMITTAL REC'O "'V'I .- ~\d:"-'~\~ en . . 5.0 CONCLUSION The preliminary stormwater drainage facilities planned for the proposed development will be adequate to convey runoff from the proposed development. The vegetated swale will provide required water quality of the expected runoff. In large storm events, the swale is provided with an overflow to direct floodwaters to the existing stormwater system located on the property leading to the storm system located on the north side of the property, and away from the subject site and adjacent properties.
