PRE-SUBMITTAL REC'O MAY 8 2008 OVERVIEW 1.0 INTRODUCTION The subject property involved in the proposed development is a gently sloping 0.82-acre development site, currently undeveloped. The site is on the current Tax' Lot 2708,pending partition (pre-submittal # PRE 2007-00067), Assessor's Map 17-03-22. The site is bounded on' the East by the future 0.88-acre lot bordering Game Farm Road, bounded on the West by Pheasant Boulevard, and bOlmded on the North and South by ,existing buildings. Three dental buildings are proposed on the subject property, complete with a parking lot, sanitary sewers, and storm drainage infrastructure to carry nmoff from the development to the existing public storm system. The proposed development is planned for submittal to the City of Springfield for Site Review. Seventy-seven percent (see calculation page of Appendix A) of the new non-building runoff will . be treated with a vegetated swale. Stormwater runoff from the west paved area on the site will be directed to the. vegetated swale. Catch basins will be placed in the swale for catching overflow. The vegetated swale will filter pollutants and sediments from the run-off and the planting of trees within the swale' will further pre-treat the stormwater runoff by reducing the temperature of the runoff before it enters the public system. Run-off from the southeast parking are will be collected with a catch basin equipped with filter and oil/water 'separator and join with the swale overflow pipe connection with the city stormwater system. Roof mn-off is routed through the new system on the site and joining with the swale overflow pipe connecting with the city stormwater 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 yegetated 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. Mid-Level Developmimt Study is required using Unit Hydrograph methods. 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 RECIO MAY 8 2008 HYDROLOGIC AND HYDRAULIC CALCULATIONS GAME FARM DENTAL: 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 Santa Barbara Urban Hydrograph (SBUH) method was used to determine the pre- development and post-development nmoff 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 SBUH was proportioned by area and used to size the drainage pipes for the post-development nmoff from the site (2-year and 25-year event). Time of Concentration: The Time of Concentration for the pre-development conditions was determined using an initial time of 10 minutes, and then adding the calculated travel time for pipe flow, gutter flow, and flow to the existing catch basin from the most remote point in the basin. The pipe flow calculations were determined using Manning's Equation for pipe flow. Specific Time of Concentration calculations for the pre-development conditions are included in Appendix A. The Time of Concentration for the post-development conditions was provided by the City of Springfield staff to be 10 minutes. Manning's Kinematic Solution for sheet flow: T = 0.42(nsL)'8 I p0.527 0.4 2 So where: ns = Manning's roughness coefficient for sheet flow L = flow length in feet P2 = 2 year, 24-hour rainfall So= land slope in filft As shown in Appendix A: . The Time of Concentration for the pre-development (existing) conditions was calculated to be 15 minutes: PRE-SUBMIlTAL RECIO 3.0 PIPE SIZING MAY 82008 The pipe sizing calculations is included in Appendix A. Required flows for the swale and the. new stormwater pipe system 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 fils 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 nahrral percolation. The vegetation will also aid in cooling the water prior to disposal in the public system. Swale design guidelines were obtained from the Blrreau 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 C3. Requirements from the BES manual using the presumptive approach were used to calculate the necessary swale dimensions for the post-development runoff. Calculations are included in Appendix A 5.0 CONCLUSION The preliminary stormwater drainage facilities planned for the proposed development will be .adequate to convey nmoff 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 Main Street storm system, and away from the subject site and adjacent properties.
