Finding: The proposed new primary dwelling height will exceed the existing home proposed as the ADU. Finding: The addition of the ADU will not exceed the 45% maximum parcel coverage of the zoning district. ELECTRIC & WATER LITILITIE Finding: Section 4.3-130.A of the Springfield Development Code requires each development area to be provided with a water system having sufficiently sized mains and 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. Finding: The ADU will require its own water and electric meter that will each need three feet of clearance around the meter. Condition of Approval: Prior to Building Permit approval, the applicant shall coordinate with Springfield Utility Board prior to trenching for the underground electric and water utilities and for final meter location approval. This information shall be shown on the Building Permit. 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.

This connection is adequate for the proposed additional home on this site. STQRMWATER MANAGEMENT Finding: Section 4.3-110.13 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 4.3-110.0 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. 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. 811-20-000162-TYP1 2 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.

It may be possible to use an infiltration planter for both the parking area and the new home roof discharge. A 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) appropriated 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 future Stormwater Facilities Master Plan (SFMP). Finding: As required in Section 4.3-110.E of the SDC, "a development shall be required to employ drainage management practices approved by the Public Works Director and consistent with Metro Plan policies and the Engineering Design Standards and Procedures Manual."

ADVISORYNOTE: Use of the recommended infiltration swale or planter to limit stormwater runoff from the driveway/parking area will also meet this requirement Finding: The vegetation proposed for use in the treatment areas 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.
