The recommended findings and conditions outlined below are provided for your use in preparing the land-use decision. 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. Finding: Public Works records show that the parcel being developed under this application has never been assessed for the cost of the public sewer system. Condition: Prior to approval of the final site plan, the applicant shall pay the sewer in lieu of assessment charge for the portion of the lot being developed. The amount is listed under Fees and Permits. Finding: the applicant has provided for adequate connection to the sanitary sewer system for the proposed development. STORMWATER MANAGEMENT Finding: Section 4.3-110.B of the SDC requires that the Approval Authority shall grant development approval only where adequate public and/or private stormwater management systems provisions have been made as determined by the Public Works Director, consistent with the Engineering Design Standards and Procedures Manual (EDSPM). Finding: Section 4.3-110.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. Finding: Section 4.3-110.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: To comply with Sections 4.3-110.D & E, stormwater runoff from the site will be directed into a series of rain gardens with sufficient capacity to infiltrate all design fi storms. WATER OUALITY Finding: Under Federal regulation of the Clean Water Act (CWA), Endangered Species Act (ESA), and National Pollutant Discharge Elimination System (NPDES), the City of 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 Environmental Quality (ODEQ) rules require 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, 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) appropriate for the community. Finding: Minimum Control Measure 5 requires the City of Springfield use an ordinance or other regulatory mechanism to address post construction runoff from new and re- development projects to the extent allowable under State law. Regulatory mechanisms used by the City include the Springfield Development Code (SDC), the City's Engineering Design Standards and Procedures Manual (EDSPM) and the Stormwater Facilities Master Plan (SFMP). 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 the City of Eugene-Stormwater Management Manual. Finding: 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: To meet the requirements of the City's MS4 permit, the Springfield Development Code, and the City's EDSPM, the applicant has proposed two rain gardens. Finding: The vegetation proposed for use in the rain gardens will serve as the primary pollutant removal mechanism for the stormwater runoff. Satisfactory pollutant removal will occur only when the vegetation has been fully established. • • Condition: Prior to approval of the final site plan, the applicant shall provide an operations and maintenance plan to the City for review to ensure the long-term maintenance and operation of the proposed rain gardens. The plan should designate maintenance responsibility for operating and maintaining the system, and should be distributed to all property owners and tenants of the site. Condition: To ensure a fully functioning water quality system and meet objectives of Springfield's MS4 permit, the Springfield Development Code and the EDSPM, the proposed rain gardens shall be shall be fully vegetated with all vegetation species established prior to approval of the final site inspection. Alternatively, if this condition cannot be met, the applicant shall provide and maintain additional interim erosion control/water quality measures acceptable to the Public Works Department that will suffice until such time as the rain garden vegetation becomes fully established. OTHER NOTE: The intent of this list is to give a developer insight about requirements that may apply before they develop their property. 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 the time of permit submittal for buildings or site improvements on each portion or phase of the development. Currently this rate has been reduced by 50%by the City Council to encourage development within the City of Springfield. An estimate is provided showing both the current, reduced rate and the full rate. SANITARY SEWER IN-LIEU-OF-ASSESSMENT CHARGE: Pay a Sanitary Sewer hi-Lieu-of-Assessment charge in addition to the regular connection fees if the property or portions of the property being developed have not previously been assessed or otherwise participated in the cost of a public sanitary sewer. Our records show this property has NOT been assessed for sewer. The charge for the proposed development is $10,080, and covers the area of development only. The remaining portion of the lot will still require an assessment fee to be paid at the time of development. Currently this charge would be $8,608 for the remaining fiscal year(until July 1, 2013). • • 1 OTHER PUBLIC WORKS PERMITS: Curb cut permit Driveway permit Land & Drainage Alteration Permits (LDAP).
