From:
S ubj ect:
I have reviewed the materials provided with the subject application. 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. J
Additionally, installation of sanitary sewers shall provide suffiCient access for
maintenance activities.
Finding: Pursuant to Chapter 3.03.4.A of the 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 stormwater
runoff, and directed to the sanitary sewer system. The applicant has complied with this
provision as shown on Sheet 3.
Finding: The applicant has not shown sanitary sewer service to the house located at 1450 J
Centennial Boulevard (T.L. 8200). The service is provided across T.L. 8300. A private
utility easement is not shown for this lateral.
Condition: The applicant shall depict the sanitary sewer service for T:L. 8200. The /
applicant shall also provide a private utility easement for the sanitary sewer line
that crosses T.L. 8300.
STORMW ATER MANAGEMENT
Finding: Section 4.3-11O.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
(EDSP M).
Finding: Section 4.3-11O.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. 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: To comply with Sections 4.3-11 O.D & E, stormwater runoff from the parking
.
.
areas will be directed into a new vegetated swale or an existing catch basin. The /
applicant proposes to connect to the public system as shown on Sheet 3. The proposed ../
connection point is in the right-of-way, and does not comply with City of Springfield
stand<l!"ds. . \
-....... . .-.:..:........-....i,:_..J.."..'t..,
. '" .'.l'.t
Condition: The applig~iri shalhoiinect to the back of the existing catch basin (at J
the property line), instead of the public line to the east ofthe catch basin (public
right-of-way).
Finding: The vegetation proposed for use in the vegetative swalewill 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.
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 vegetative swales, shall be fully vegetated with all vegetation species /
established prior to issuance of the tentative occupancy building permit. J
Alternatively, is 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 swale
vegetation becomes fully established.
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
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 EnvironmentaI 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
Stormwatef 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 3.02 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).
UTILITIES. EASEMENTS AND RIGHTS OF WAY
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: Section 4.3-140.A of the SDC requires applicants proposing developments
make arrangements with the City and each utility provider for the dedication of utility
easements necessary to fully service the development or land beyond the development
area. The minimum width for public utility easements adjacent to street rights of ways
shall be 7 feet. The minimum width for all other public utility easements shall be 7 feet.
The Public Works Director may require a larger easement to allow for adequate
maintenance.
Finding: The applicant has proposed a 7.0' P.U.E. along the Centennial Boulevard and
the Market Street frontage of the parcel.
