Finding: No additional information is provided as part of this application for sizing, infiltration capacity or
planting for the proposed facilities.
Condition of Approval: Prior to Building Permit approval, the applicant shall provide stormwater
calculations for all new impervious areas showing that the facilities are appropriately sized and that
the areas draining into them.
WATEROUALITY
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 (M54) 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 M54 plan
address six "Minimum Control Measures." Minimum Control Measure 5, "Post-Construction Stormwater
Management for New Development and Redevelopmeng" 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 runofffrom 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."
Finding: Section 3.01 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 City of Eugene Stormwater
Management Manual.
Finding: Section 3.02 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 runoffgenerated 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 M54 permit, the Springfield Development Code, and the City's
EDSPM, the applicant has proposed stormwater planter adjacent to the driveway for treating and infiltrating
this area.
Finding: The vegetation proposed for use in the swales will serve as the primary pollutant removal
mechanism for the stormwater runofl 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.
Finding: The location of the stormwater planter area has not been shown with sufficient details to meet the
requirements set forth in Eugene Stormwater Management Manual. There was no inclusion of a stormwater
treatment area detail drawing on the plan set.
Condition of Approval: Prior to Building Permit approval, 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 Stormfilter Catchbasin and planter area, consistent with maintenance criteria required
J81 1 -20-000195-TYP1
by EDSPM 3.03.1. 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 of Approval: Prior to Building Permit approval, the applicant shall submit a suitable
vegetation plan for the proposed stormwater planter area. The City of Eugene stormwater
management manual and Chapter 6 of the EDSPM may be referenced for design.
Condition of Approval: To ensure a fully functioning water quality system and meet obiectives of
Springfield's MS4 permit, the Springfield Development Code and the EDSPM, the proposed
stormwater planter area shall be fully vegetated with all vegetation species established prior to
approval of Final site inspection. Alternatively, if this condition cannotbe met the applicantshall
provide and maintain additional interim erosion control/water quality measures acceptable to the
Public Works Department that will suffice until such time as the swale vegetation becomes fully
established.
