Steps in the Process:
1. The Applicant Submits a Pre-Submittal Meeting Application
.
.
, ,
The Pre-Submittal Application is mandatory. Please refer to the Springfield Fee Schedule
for the Pre-Submittal Application fee. The submittal package must conform to the
application completeness checklist attached to this form. You are required to submit Nine
(9) copies of the submittal requirements packet for pre-submittal review. Pre-submittal
meetings will be conducted every Tuesday and Friday between 10:00 am and noon. We
will strive to conduct the Pre-Submittal meeting within five to seven working days of
receiving the application.
2. Applicant and the City conduct the Pre-Submittal Meeting
We strongly encourage you, the owner and design team to attend the Pre-Submittal
meeting. The meeting will be held with representatives from Public Works Engineering
and Transportation, Community Services (Building), Fire Marshall's office, and the
Planning Division. The meeting will be scheduled for 30 to 60 minutes. The Planner will
provide you with a Pre-Submittal Checklist at the end of the meeting specifying the items
required to make the application complete-if it isn't already complete. You will then have
180 days to make the application complete for submittal and acceptance by the City.
3. Applicant Submits a Complete Application
When you have addressed all of the items on the Pre-Submittal Checklist, please submit
18 copies of the complete application to the City. A fee will be collected at that time and
the 120 day calendar review period will begin. When the Planner has prepared a draft
land use decision, the draft will be mailed/faxed to the applicant/owner/design team for
their review. At the applicant's request, the planner will schedule a meeting to review the
draft with appropriate staff if certain issues need resolution before the final land use
decision is issued.
Owner's Signature
This application will be used for both the required Pre-Submittal Meeting and subsequent
complete application submittal. Owner's signatures are required at both stages in the
application process. An application without the Owner's signature will not be
accepted.
The undersigned acknowledges that the information in this application is correct and accurate
for scheduling of the Pre-Submittal Meeting.

OVERVIEW
1.0 INTRODUCTION
The subject property involved in the proposed development is a gently sloping 0.54-acre
development site, currently undeveloped. The site is on Tax Lot 1100 Assessor's Map 17-03-15-
33. The site is bounded on the North by Game Farm Road, and is bounded on the South, East,
and West by adjacent lots (near Gateway Street). A 200 square foot coffee kiosk is proposed on
the subject property, complete with 2 drive aisle, sanitary sewers, and storm drainage
infrastructure to carry runoff from the development to the existing public storm system. 4,128
square feet of new or replaced non building surface will be added to site.
All of the new non-building runoff will be treated with a vegetated swale. Stormwater runoff
from the paved area on the site will be directed through a curb cut to the vegetated swale. Catch
basins will be placed in the swale for catching overflow. Roof and sidewalk run-off is routed to
the existing system on the site. The vegetated swale will filter pollutants and sediments from the
run-off and the planting of trees within the swale and detention pond areas will further pre-treat
the stormwater runoff by reducing the temperature of the runoff before it enters the public
system.
Hydrologic calculations to determine the existing (pre-development) and proposed (post-
development) runoff amounts are included, as are hydraulic calculations to determine pipe
sizing, and calculations to determine the sizing of the proposed vegetated swale.
A "Stormwater Management System Scope of Work" sheet was submitted to the City for the
proposed development. The scoping sheet states that a downstream analysis of the receiving
system is not required for this report. Small Site Study is required using the Rational Method for
runoff.
2.0 PURPOSE
The purpose of this report is to attempt to comply with the requirements of Article 32.110
Stormwater Management of the Springfield Development Code, and the Springfield Public
Works Engineering Design Standards and Procedures, dated April 2006.
PRE-SUBMITTAL REC'O

HYDROLOGIC AND HYDRAULIC CALCULATIONS
DARI MART ADDITION:
1.0 PURPOSE
The purpose of these hydrologic and hydraulic calculations is to determine the runoff flows from
the subject property for both pre-development and post-development conditions, and to verify
pipe and swale sizing for the proposed development.
2.0 CALCULATION METHODS
The Rational Method was used to determine the post-development runoff from the site. Excel
software was used to perform the specific calculations. The input variables and resulting flow
rates are included in Appendix A. The flow calculated from the Rational Method was used to
size the drainage pipes for the post-development runoff from the site (25-year event).
Time of Concentration:
The Time of Concentration for the pre-development conditions was determined using an initial
time of 10 minutes. The pipe flow calculations were determined using Manning's Equation for
pipe flow.
3.0 PIPE SIZING
The pipe sizing calculations is included in Appendix A. Required flows to the swale and the
existing 8-inch stormwater pipe were proportioned from the site peak-flow calculation and areas
being drained. A Manning's n value of n = 0.013 was used for PVC pipes per City of
Springfield Engineering Design Standards manual, achieving a minimum cleansing velocity 3.0
ft/s for all new pipes.
4.0 SW ALE/CONVEYANCE
A vegetated swale was chosen as the best method for pre-treating the stormwater runoff by
allowing for natural percolation. The vegetation will also aid in cooling the water prior to
disposal in the public system. Swale design guidelines were obtained from the Bureau of
Environmental Services-City of Portland (BES) manual. A detail from the BES manual is
included in Appendix B, while the specific dimensions and layout of the swale design is shown
on the Grading Plan, Sheet C2.
Form SIM from the BES manual was used to calculate the necessary swale dimensions for the
post-development runoff. Tree credits were taken as applicable from the landscape architect's
plans. The Form SIM is included as Appendix B. The required swale size was calculated to be
372 square feet. The site provides 972 square feet of swale.

5.0 CONCLUSION
The preliminary stormwater drainage facilities planned for the proposed development will be
adequate to convey runoff from the proposed development. The vegetated swale will provide
required water quality of the expected runoff. In large storm events, the swale is provided with
an overflow to direct floodwaters to the existing stormwater system located on the property
leading to the storm system located on the north side of the property, and away from the subject
site and adjacent properties.
