The recommended findings and conditions outlined below are provided for your use in preparing the land-use decision. ,j SANITARY SEWER Finding: Section 4.3-105.A of the SDC requires that sanitary sewers shall be installed to serve each new development and to connect developments to existing mains. Additionally, installation of sanitary sewers shall provide sufficient access for maintenance activities. < J Finding: Section 4.3-105.C of the SDC requires that proposed sewer systems shall include design consideration of additional development within the area as projected by the Metro Plan. j Finding: Pursuant to Chapter 3.03.4.A ofthe City's Engineering Design Standards and Procedures Manual and Section 4.4 of Portland's Stormwater Management Manual, solid waste storage areas shall be covered and hydraulically isolated from potential storm water runoff, and directed to the sanitary sewer system. Finding: The application does not appear to alter the already approved sewer plans for this development. STORMW A TER MANAGEMENT Finding: Section 4.3-110.B of the SDC requires that the Approval Authority shall grant J development approval ollIywhere adequate public and/or priv~te stormwater management systems provisions have been made as determined by the Public Works Director, consistent with the Engineering Design Standards and Procedures Manual (EDSPM). j Finding: Section 4.3-11 O.C of the SDC states that a stormwater management system shall accommodate potential run-off from its entire upstream drainage area, whether inside or outside of the development. jFinding: Section 4.3-11 O.D of the SDC requires that run-off from a development shall be directed to an approved stormwater management system with sufficient capacity to accept the discharge. . ... t . ua 1':/ V(6ceived: Planner: AL ';/;0/,)001 I / . /Finding: Section 4.3-11O.E of the SDC requires new developments to employ drainage management practices, which minimize the amount and rate of surface water -run-off into receiving streams, and which promote water quality. / Finding:. The proposed site modifications will do not appear to substantially change the - runoff characteristics of the site and no change is required. WATEROUALITY Finding: Under Federal regulation of the Clean Water Act (CW A), Endangered Species Act (ESA), and National Pollutant Discharge Elimination System (NPDES), the City of j Springfield has obtained a Municipal Separate Storm Sewer System (MS4) permit. A provision of this permit requires the City demonstrate efforts to reduce the pollution in urban stormwater to the Maximum Extent Practicable (MEP). Finding: Federal and Oregon Department of Environmenta! Quality (ODEQ) rules jrequire the City's MS4 plan address six "Minimum Control Measures." Minimum Control Measure 5, "Post-Construction Stormwater Management for New Development and Redevelopment," applies to the proposed development. Finding: Minimum Control Measure 5 requires the City of Springfield to develop, j implement and enforce a program to ensure the reduction of pollutants in stormwater runoff to the MEP. The City must also develop and implement strategies that include a combination of structural or non-structural Best Management Practices (BMPs) appropriated for the community. j Finding: Section 3.02 of the City's EDSPM states the Public Works Department will accept, as interim design standards for stormwater quality, water quality facilities designed pursuant to the policies and procedures of either the City of Portland (BES), or the Clean Water Services (CWS). jFinding: Section 3.03.3.B of the City's EDSPM states all public and private development and redevelopment projects shall employ a system of one or more post-developed BMPs that in combination are designed to achieve at least a 70 percent reduction in the total suspended solids in the runoff generated by that development. Section 3.03.4.E of the manual requires a minimum of 50 percent of the non-building rooftop impervious area on a site shall be treated for stormwater quality improvement using vegetative methods. / Finding: The vegetation proposed for use in the swales will serve as the primary pollutant removal mechanism for the stormwater runoff, and will remove suspended solids and pollutants through the processes of sedimentation and filtration. Satisfactory pollutant removal will occur only when the vegetation has been fully established. J Finding: The proposed site modifications will not alter the proposed/existing storm water quality measures and no change is needed from the existing design. watE, Heceived: 2 /;/o/~O'1 Planner: AL 7 . PUBLIC STREETS. SIDEWALKS & IMPROVEMENT AGREEMENTS Finding: Section 4.2-105.G.2 of the Springfield Development Code requires that whenever a proposed land division or development will increase traffic on the City street system and that development has any unimproved street frontage abutting a fully /improved street, that street frontage shall be fully improved to City specifications. Exception (i) notes that in cases of unimproved streets, an Improvement Agreement shall be required as a condition of Development Approval postponing improvements until such time that a City street improvement project is initiated. Finding: The proposed site modifications will not impact the public access points of this site in a substantial way. UTILITIES. EASEMENTS AND RIGHTS OF WAX Finding: Section 4.3-130.A ofthe Springfield Development Code requires each development area to be provided with a water system having sufficiently sized mains and j lesser lines to furnish adequate supply to the development and sufficient access for maintenance. Springfield Utility Board coordinates the design of the water system within Springfield city limits. The current plan proposal does not show locations or sizes of proposed water lines. Finding: The proposed site modifications will impact the public utilities to this site in a substantial way. FEES AND PERMITS SYSTEMS DEVELOPMENT CHARGE: Pay applicable Systems Development Charges when building permits are issued for developments within the City limits or within the Springfield Urban Growth Boundary. (The cost relates to the amount of increase in impervious surface area, transportation trip rates, and plumbing fixture units. Some exceptions apply to Springfield Urban Growth areas.) [Springfield Code Chapter II, Article 11] Systems Development Charges (SDC's) will apply to the construction of buildings and site improvements within the subject site. The Charges will be based upon the rates in effect at tpe time of permit submittal for buildings or site improvements on each portion or phase of the development.
