serve each new development and to connect developments to existing mains. /
Additionally, installation of sanitary sewers shall provide sufficient access for
maintenance activities.
Finding: Section 4.3-105.C ofthe SDC requires that proposed sewer systems shall
include design consideration of additional development within the area as projected by
the Metro Plan.
/ Finding: Pursuant to Chapter 3.03.4.A of the City's Engineering Design Standards and
.J (.x\1I' Procedures Manual and Section 4.4 of Portland's Stormwater Management Manual, solid
fnit' waste storage areas shall be covered and hydraulically isolated from potential storm water
/.;~- ~ runoff, and directed to the sanitary sewer system. ,

STORMWATER MANAGEMENT
Finding: Section 4.3- I I O.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- I 10.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- I I O.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. '. . ~

WATER QUALITY
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
Springfield has obtained a Municipal Separate Storm Sewer System (MS4) permit. A
provision ofthis 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 4.3-11 O.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 3.02 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).
",
Finding: Section 3.03.3.B ofthe City's EDSPM states all public arid 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 ofthe City's MS4 . , he Springfield
Development Code, and the City's EDSPM, the ap lcant has p posed one private rain
garden and two private catch basins with filters. s ecific . ns or maintenance plan
. 'for'the'catch'.basins has been submitted with the apphca IOn.

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 estab .

\II Condition: Prior to Final PIal ~pproval, the applicant shall add a note to the grading plan
and the landscape plan that the vegetated rain garden area will be scarified/roto-tilled to /'
remove any compaction of the soil prior to planting of the ~~atively the area
can be protected from equipment compaction similar to tree protection areas.
Condition: Prior to approval of the [mal 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 catchbasins, consistent with maintenance /'
criteria required by the manufacturer. 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 <;:ode and the EDSPM, the /
proposed private rain garden shall be fully vegetated with all vegetation species
established prior to approval of Final Plat. Alternatively, if this condition cannot be met,
the applicant shall provide and maintain additional interim erosion controllwater quality
measures acceptable to the Public Works Department that will suffice until such time as
the swale vegetation becomes fully. established.
PUBLIC STREETS. SIDEWALKS & IMPROVEMENT AGREEMENTS
Finding: The applicant has proposed construction adjoining the existing paved alley
along the rear of the proposed project. The alley will provide construction access and be
used to access several parking spaces for the proposed apartments. In addition the alley
contains public stormwater improvements.
Condition: The alley is not improved to public street standards for width or load bearing
capacity. Prior to construction a joint walk through ofthe alley shall be conducted by
city staff and owners representative to document existing condition ofthe alley. The
applicant shall be responsible for any damage caused to alley by construction activity.

UTILITIES. EASEMENTS AND'RIGHTS OF WAY
Finding: Section 4.3-130,A of the Springfield Development Code requires each
de.velopment 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. .
OTHER
NOTE: The intent of this list is to give a developer insight about requirements related to
public improvements before they develop their property.
