MAY CREEK - CANYON OAKS
STORM DRAIN CALCULATIONS
January, 1988
Calculations for capacity check were done based upon flowing full condition of the
catch basin at Sta. 3 + 29.15 (see May Creek - Canyon Oaks plans for reference) being
full to the ground elevation. Using this condition combined with the ground elevation at
the catch basins immediately upstream of the catch basin at Sta. 3 + 29.15 (for the 18"
and 12" pipes), the head water available can be calculated. Maximum flows through the
pipes were determined to be 4.58 c.f.s. and 13.18 c.f.s. for the 12" and 18" respectively.
This yields a total maximum inflow of 17.76 c.f.s. at the catch basin at Sta. 3 + 29.15.
The outflow in this condition was found to be inlet controlled due to the large slopes of
the polyethylene pipe running down the slope. Inlet flow for the existing HW/D was
found to be approximately 18 c.f.s. which is adequate to pass the maximum inflow.
These calculations reflect the maximum flow which can reach the catch basin in
question. It can be seen that the catch basins upstream will overtop before any more
flow will reach the catch basin at Sta. 3 + 29.15 causing it to overflow.

This letter is to inform you that the Environmental Review Committee completed their
review of the environmental impacts of the above referenced project. The Committee on
August 5, 1988, decided that your project may be issued a Determination of Non -
Significance -Mitigated with the following condition:
1. That the applicant complete all project construction and related improvement
activities (reseeding, rip -rapping, etc.) no later than October 31, 1988.
Because the Environmental Review Committee imposed specific mitigation measures rather
than issue a Determination of Significance, there is a required fifteen (15) day comment
period during which comments are solicited from various agencies, jurisdictions or
individuals who may have an interest in the Committee's decision. The comment period will
end August 29, 1988. Following the end of the comment period, the City will finalize it's
Determination unless comments received require a reevaluation. Following the finalization
of the Determination, there is a required fourteen (14) day appeal period.
If you have any questions or desire clarification of the above, either Jeanette or I should be
able to answer them. The reason for the cut off at the end of October, was the Committee's
concern about erosion during the wet season.

MEMORANDUM
DATE: July 26, 1988
TO: Don Erickson, Zoning Administrator
FROM: Bob Bergstrom, Engineering Supervisor
SUBJECT: Kennewick Place NE - (May Creek) Erosion Control Project
ECF-039-88; SM-039-88
Dear Don:
In response to the additional materials requested by the Technical Advisory Committee, as
outlined in you letter dated July 8, 1988, 1 have enclosed the following information and
three exhibits: Exhibit "A" shows the Calculations for the storm outfall, Exhibit "B" is
the Preliminary Special Provisions for the project, and Exhibit "C" is a June 30, 1988 Memo
explaining use of materials.
I. Information describing present volume of storm water runoff and anticipated chances in
that volume when the project is complete:
The storm drain calculations included as Exhibit "A" showed that the flow to this outfall
was restricted by the upstream elevations which will remain unchanged. Combined with an
unchanged headwater for the inlet conditions downstream at the manhole 3 + 29.15, this
demonstrated that there will be no increase in the runoff volume encountered through the
outfall.
2. Statement describing plans for greenbelt protection during project construction:
Exhibit "B" is a copy of the preliminary special provisions which address green belt
protection through special measures (i.e. no heavy trenching equipment to be used, timber
pad crossing of May Creek, no wheeled or tracked vehicles in the stream bed, blending
trench naturally, and covering with jute matting and seeding). Protection will also be
addressed in the Temporary Erosion Control Plan to be submitted by the Contractor.
3. Statement describing the capacity of the proposed 18" storm drain and ways in which
various types/intensity of future development in the vicinity may affect the effectiveness
of the proposed system:
The capacity of the 18" storm drain, as addressed in the calculations included as
Exhibit "A", is inlet controlled with a capacity of 18 cubic feet per second. As the outfall
is located in the May Creek basin, any development in the basin is restricted to an existing
5 year storm event maximum release rate with a detention requirement for a 25 year storm
event. This will have the effect of decreasing the flows for the 25 year storm event. Any
flows in excess of this event will be stored in upstream areas due to the flow conditions in
the upstream pipes.

4. Description of temporary erosions control measures to be used in coniunction with this
pro iect:
The temporary erosion control plan will include, but not be limited to: the use of siltation
fence, a construction entrance from Jones Road, and jute matting with seeding. Exact
details of the plan are to be submitted by the Contractor for City approval prior to the
start of construction.
5. An overall statement of the construction scenario for the nroiect including rationale for
materials used:
A. The Contractor is required to submit a detailed outline and time table for the progression
of work prior to construction start. The outline should basically follow the procedural
steps as detailed below:
1. Install temporary erosion control measures.
2. Stake construction easement.
3. Clear and grub for construction of storm line.
4. Construction stake for storm line.
5. Begin trenching, laying pipe, covering, and grading as construction proceeds, laying
jute matting and seeding over the exposed areas when finished grade is attained.
6. Place the energy dissipater on the lower end of the polyethylene pipe.
7. Construct outfall with a rock -lined channel leading to May Creek.
8. Plug existing 18" CMP to the west.
9. Finish and cleanup (removal of construction entrance and any additional seeding as
necessary.)
B. As to the rational for materials used, please see the memorandum I wrote on June 30, 1988
which has been included as Exhibit "C".
I hope that this information has addressed all of the questions you have regarding the
Kennewick Place NE Erosion Control Project, and that it will allow for the review of the
application to proceed.

MAY CREEK - CANYON OAKS
STORM DRAIN CALCULATIONS
January, 1988
Calculations for capacity check were done based upon flowing full condition of the
catch basin at Sta. 3 + 29.15 (see May Creek - Canyon Oaks plans for reference) being
full to the ground elevation. Using this condition combined with the ground elevation at
the catch basins immediately upstream of the catch basin at Sta. 3 + 29.15 (for the 18"
and 12" pipes), the head water available can be calculated. Maximum flows through the
pipes were -determined to be 4.58 c.f.s. and 13.18 c.f.s. for the 12" and 18" respectively.
This yields a.'total maximum inflow of 17.76 c.f.s. at the catch basin at Sta. 3 + 29.15.
The outflow in this condition was found to be inlet controlled due to the large slopes of
the polyethylene pipe running down the slope., Inlet flow for the existing HW/D was
found to be approximately 18 c.f.s. which is adequate to pass the maximum inflow.
These calculations reflect the maximum flow which can reach the catch basin in
question. -It can be seen that the catch basins upstream will overtop before,,any more
flow will reach the catch basin at Sta. 3 + 29.15 causing it ,to overflow.'

SUBJECT: Canyon Oaks Storm Drain and Erosion Control Project
SEPA Review
I have been asked to elaborate on -two design issues concerning the
proposed Canyon Oaks storm sewer.
As you may recall, Public Works submitted this project for SEPA and
Shorelines review. This project reconstructs a new storm water pi°pe:to'?,,
replace the badly eroded Canyon Oaks gully that carries storm runoff from
Kennewick Ave. N.E. to May Creek. ,
The two questions are;
1•AV wasteOjY ethylene sewer pipe specified? This pipe material was
specifically required by King County Parks, the landowner of the
property we will cross with the sewer. Renton Public Works agrees
that this pipe has superior strength ian'd,flowic•haracteristics. We
have used this material in similar work for the Honey Creek sanitary
sewer. The City of Seattle and King County have used Polyethylene
pipe in curved alignments'to solve many erosion problems.
2=' Why was a rock rip-rap`spill pad used at'the'pipe line outfall? An
erosion control/energy dissipator was needed prior to storm water
discharge into May Creek. The preliminary design,scoped in the May
Creek Drainage Comprehensive Plan outlined in -pipe or in -manhole
energy dissipators. The design of the rock splash pad was
coordinated with ,the State Department of Fisheries and was considered
to be superior to an in -pipe energy dissipator. An above ground rock
pad could be visually inspected, easy to clean, and has the potential
to develop vegetation and some bio-filtration.
I hope these items will clarify and release the SEPA and Shorelines
review.

outlined in you letter dated July 8, 1988, I have enclosed the following information and
three exhibits: Exhibit "A" shows the Calculations for the storm outfall, Exhibit "B" is
the Preliminary Special Provisions for the project, and Exhibit "C" is a June 30, 1988 Memo
explaining use of materials.
1. Information describing present volume of storm water runoff and anticipated changes in
that volume when the proiect is complete:
The storm drain calculations included as Exhibit "A" showed that the flow to this outfall
was restricted by the upstream elevations which will remain unchanged. Combined with an
unchanged headwater for the inlet conditions downstream at the manhole 3 + 29.15, this
demonstrated that there will be no increase in the runoff volume encountered through the
outfall.
2. Statement describing plans for greenbelt protection during proiect construction:
Exhibit "B" is a copy of the preliminary special provisions which address green belt
protection through special measures (i.e. no heavy trenching equipment to be used, timber
pad crossing of May Creek, no wheeled or tracked vehicles in the stream bed, blending
trench naturally, and covering with jute matting and seeding). Protection will also be
addressed in the Temporary Erosion Control Plan to be submitted by the Contractor.
3. Statement describing the capacity of the proposed 18" storm drain and ways in which
various types/intensity of future development in the vicinity may affect the effectiveness
of the proposed system:
The capacity of the 18" storm drain, as addressed in the calculations included as
Exhibit "A", is inlet controlled with a capacity of 18 cubic feet per second. As the outfall
is located in the May Creek basin, any development in the basin is restricted to an existing
5 year storm event maximum release rate with a detention requirement for a 25 year storm
event. This will have the effect of decreasing the flows for the 25 year storm event. Any
flows in excess of this event will be stored in upstream areas due to the flow conditions in
the upstream pipes.

4. Description of temporary erosions control measures to be used in conjunction with this
rn oiect:
The temporary erosion control plan will include, but not be limited to: the use of siltation
fence, a construction entrance from Jones Road, and jute matting with seeding. Exact
details of the plan are to be submitted by the Contractor for City approval prior to the
start of construction.
5. An overall statement of the construction scenario for the proiect including rationale for
materials used:
A. The Contractor is required to submit a detailed outline and time table for the progression
of work prior to construction start. The outline should basically follow the procedural
steps as detailed below:
1. Install temporary erosion control measures.
2. Stake construction easement.
3. Clear and grub for construction of storm line.
4. Construction stake for storm line.
5. Begin trenching, laying pipe, covering, and grading as construction proceeds, laying
jute matting and seeding over the exposed areas when finished grade is attained.
6. -Place the energy dissipater on the lower end of the polyethylene pipe.
7. Construct outfall with a rock -lined channel leading to May Creek.
8. Plug existing 18" CMP to the west.
9. Finish and cleanup (removal of construction entrance and any additional seeding as
necessary.)
B. As to the rational for materials used, please see the memorandum I wrote on June 30, 1988
which has been included as Exhibit "C".
I hope that this information has addressed all of the questions you have regarding the
Kennewick Place NE Erosion Control Project, and that it will allow for the review of the
application to proceed.

MAY CREEK - CANYON OAKS
STORM DRAIN CALCULATIONS
January, 1988
Calculations for capacity check were done based upon flowing full condition of the
catch basin at Sta. 3 + 29.15 (see May Creek - Canyon Oaks plans for reference) being
full to the ground elevation. Using this condition combined with the ground elevation at
the catch basins immediately upstream of the catch basin at Sta. 3 + 29.15 (for the 18"
and 12" pipes), the head water available can be calculated. Maximum flows through the
pipes were determined to be 4.58 c.f.s. and 13.18 c.f.s. for the 12" and 18" respectively.
This yields a total maximum inflow of 17.76 c.f.s. at the catch basin at Sta. 3 + 29.15.
The outflow in this condition was found to be inlet controlled due to the large slopes of
the polyethylene pipe running down the slope. Inlet flow for the existing HW/D was
found to be approximately 18 c.f.s. which is adequate to pass the maximum inflow.
These calculations reflect the maximum flow which can reach the catch basin in
question. It can be seen that ithe catch basins upstream will overtoo before, any more
flow will reach the catch basin at Sta. 3 + 29.15 causing it to overflow.

SUBJECT: Canyon Oaks Storm Drain and Erosion Control Project
SEPA Review
I have been asked to elaborate on two design issues concerning the
proposed Canyon Oaks storm sewer.
As you may recall, Public Works submitted this project for SEPA and
Shorelines review. This project reconstructs anew storm; water pipe to :
replace the badly eroded Canyon Oaks gully that carries storm runoff from
Kennewick Ave. N.E. to May Creek.
The two questions are;
1• Why was po lyethylene sewer pipe specified? This pipe material was
specifically required by King County Parks, the landowner of the
property we will•cross with the sewer. Renton Public Works agrees
that this pipe has; spp'gripr, strength landiflowicharacteristics. We
have used this material inisimilar•work for�'the Honey Creek sanitary
sewer. The City:of Seattle and King County have used Polyethylene
pipe in curved alignments'to solve many erosion problems.
2•1 Why was a rock rip —rap spi l 1
pad used at'the pipe ''
line outfall? An
erosion control/energy dissipator was needed prior to storm water
discharge into May Creek. The preliminary design,scoped in the May
Creek Drainage Comprehensive Plan outlined in''-p'ipe or in —manhole
energy dissipators. The design of'the rock splash,pad„was
coordinated with the State Department of'Fisherie's and was considered
to be superior to an 'in -pipe energy dissipator. An above ground rock
pad could be visually inspected, easy to clean, and has the potential
to develop vegetation and some bio—filtration
I hope t-he�se items'will'c'larify and release the SEPA and Shorelines

RE: May Creek Park Special Use Permit FS-59-87
Storm Drainage System
Dear Mr. Bethel:
Per your request, please find enclosed a preliminary plan of the proposed
storm drain in the vicinity of King /County May Creek Park. I am also
enclosing a copy of the Utility Use Permit issued by King County Real Property
Division in June of 1987.
Per our discussion, we will meet with you at the site on February 24, 1988, at
11:00 a.m. Should you have any questions, please contact me at 235-2631.
Very truly yours,

X-B. CORPS OF ENGINEERS STILLING WELL
The design of this type of stilling well energy dissipator j
is based on model tests conducted by the Corps of Engineers. I
(X-B-1 and 2) j
The dissipator has application where debris is not a serious
problem. It will operate with moderate to high concentra-
tions of sand and silt but is not recommended for areas where
quantities of large floating or rolling debris is expected
unless suitable debris -control structures are utilized. Its
greatest potential, as far as highways are concerned, is at
the outfalls of storm drains, median, and pipe down drains
where little debris is expected. It may also be useful as a
temporary erosion control device during construction.
Design Recommendations
The design is straightforward. Once the size and discharge
of the incoming pipe are determined, figure X-B-1 is used
to select the stilling well diameter (Dw). The model tests
indicated that satisfactory performance can be maintained
for Q/D5/2 ratios as large as 10.0, with stilling well dia-
meters of one, two, three, and five times that of the incoming
conduits. These ratios.were used to define the curves shown
in figure X-B-1.
The tests also indicated that there is an optimum depth of
stilling well below the invert of the incoming pipe. This
depth is determined by entering figure X-B-2 with the slope
of the incoming pipe and using the stilling well diameter (Dw)
previously obtained from figure X-B-1.
The height of the stilling well above the invert is fixed
at twice the diameter of the incoming pipe (2D). This
dimension results in satisfactory operation and is practical
from a cost standpoint; however, if increased, greater effi-
ciency will result.
Tailwater also increases the efficiency of the stilling well.
Whenever possible, it should be located in a sump or depressed
area.
I .
It is recommended that riprap or other types of channel pro-
tection be provided around the stilling well outlet and for
a distance of at least 3Dw downstream.
X-B-1
The outlet may also be covered with a screen or grate for
safety. However, the screen or grate should have a clear
opening area of at least 75 percent of the total stilling
well area and be capable of passing small floating debris
such as cans and bottles.
Design Procedures
(1) Select approach pipe diameter (D) and discharge (Q).
(2) Obtain well diameter (DW) from figure X-B-1.
(3) Calculate the culvert slope = (Vertical/horizontal
distance). The depth of the well below the culvert invert (hl)
is determined from figure X-B-2.
(4) The depth of the well above the culvert invert (h2)
is equal to 2(D) as a minimum but may be greater if the site
permits.
(5) The total height of the well (hW) = hl+h2.
Example Problem
Given: 24" CMP downdrain on a 2:1 slope carrying a
Q = 15 cfs
Find: Stilling well dimensions
Solution:
(1) D=2 ft., Q=15 cfs
(2) From figure X-B-1 DW=1.5D=3 ft.
(3) Slope=1/2=.5, hl/DW=.42 from figure X-B-2
hl=.42(3.0)=1.26 ft., Use hl=1.3 ft.
(4) h2=2 (D)=2 (2)=4 ft.
(5) hW= hl+h2=1.3+4=5.3 ft.

Subject: Request for Storm Drain Easement
Dear Mr. Jacobs:
Enclosed please find a pre -application questionnaire for an easement request
along with a legal description of the proposed easement, location map, and a
preliminary construction drawing of the proposed storm drain.
This easement is desired because of a storm drain washout and landslide during
the heavy rains in February, at the outfall of an 18" storm into the ravine
north of the Canyon Oaks Condominiums in north Renton. Due to the sensitive
nature of the ravine, it was decided that it would not be prudent to attempt to
repair the damaged outfall, but rather to divert the storm drain to May Creek
via a tight -line storm drain as shown on the attached maps.
The City is requesting a 15 foot permanent easement, and possibly a temporary
construction easement to install the storm drain. Your timely review of this
request would be greatly appreciated.
Should you have any questions please call me at 235-2631.
Very truly yours,
Robert L. Bray
Project Engineer

ENVIRONMENTAL CHECKLIST
O1
91TED SEPTC00"
Purpose of Checklist:
The State Environmental Policy Act (SEPA), chapter 43,21C RCW, requires all
governmental agencies to consider the environmental impacts of a proposal before making
decisions. An environmental impact statement (EIS) must be prepared for allproposals
with probable significant adverse impacts on the quality of the environment. The purpose
of this checklist is to provide information to help you and the agency identify impacts
from your proposal (and to reduce or avoid impacts from the proposal, if it can be done)
and to help the agency decide whether an EIS is required.
Instructions for Applicants:
This environmental checklist asks you to describe some basic information about your
proposal. Governmental agencies use this checklist to determine whether the
environmental impacts of your proposal are significant, requiring preparation of an EIS.
Answer the questions briefly, with the most precise information known, or give the best
description you can.
You must answer each question accurately and carefully, to the best of your
knowledge. In most cases, you should be able to answer the questions from your own
observations or project plans without the need to hire experts. If you really do not know
the answer, or if a question does not apply to your proposal, write "do not know" or "does
not apply." Complete answers to the questions now may avoid unnecessary delays later.
Some questions ask about governmental regulations, such as zoning, shoreline, and
landmark designations. Answer these questions if you can. If you have problems, the
governmental agencies can assist you.
The checklist questions apply to all parts of your proposal, eve-) if you plan to do
them over a period of time or on different parcels of land. Attach any additional
information that will help describe your proposal or its environmental effects. The
agency to which you submit this checklist may ask you to explain your answers or provide
additional information reasonably related to determining if there may be significant
adverse impacts.
Use of Checklist for Nonproject Proposals: (Please Type or Print Legibly)
Complete this checklist for nonproject proposals, even though questions may be
answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR
NONPROJECT ACTIONS (part D).
For nonproject actions (actions involving decisions on policies, plans and programs),
the references in the checklist to the words "project," "applicant," and "property or site"
should be read as "proposal," "proposer," and "affected geographic area," respectively.

Storm Water Utility
City of Renton
200 Mill Avenue South
Renton, Washington 98055
MAY CREEK - CANYON OAKS
STORM DRAIN CALCULATIONS
January, 1988
Calculations for capacity check were done based upon flowing full condition of the
catch basin at Sta. 3 + 29.15 (see May Creek - Canyon Oaks plans for reference) being
full to the ground elevation. Using this condition combined with the ground elevation at
the catch basins immediately upstream of the catch basin at Sta. 3 + 29.15 (for the 18"
and 12" pipes), the head water available can be calculated. Maximum flows through the
pipes were determined to be 4.58 c.f.s. and 13.18 c.f.s. for the 12" and 18" respectively.
This yields a total maximum inflow of 17.76 c.f.s. at the catch basin at Sta. 3 + 29.15.
The outflow in this condition was found to be inlet controlled due to the large slopes of
the polyethylene pipe running down the slope. Inlet flow for the existing HW/D was
found to be approximately 18 c.f.s. which is adequate to pass the maximum inflow.
These calculations reflect the maximum flow which can reach the catch basin in
question. It can be seen that the catch basins upstream will overtop before any more
flow will reach the catch basin at Sta. 3 + 29.15 causing it to overflow.

SEPA Review
I have been asked to elaborate on two design issues concerning the
proposed Canyon Oaks storm sewer.
As you may recall, Public Works submitted this project for SEPA and
Shorelines review. This project reconstructs a new storm water pipe to
replace the badly eroded Canyon Oaks gully that carries storm runoff from
Kennewick Ave. N.E. to May Creek.
The two questions are;
1. Why was pol ethylene sewer pipe specified? This pipe material was
specifically required by King County Parks, the landowner of the
property we will cross with the sewer. Renton Public Works agrees
that this pipe has superior strength and flow characteristics. We
have used this material in similar work for the Honey Creek sanitary
sewer. The City of Seattle and King County have used Polyethylene
pipe in curved alignments to solve many erosion problems.
2. Why was a rock rip —rap spill pad used at the pipe line outfall? An
erosion control/energy dissipator was needed prior to storm water
discharge into May Creek. The preliminary design scoped in the May
Creek Drainage Comprehensive Plan outlined in —pipe or in —manhole
energy dissipators. The design of the rock splash pad was
coordinated with the State Department of Fisheries and was considered
to be superior to an in —pipe energy dissipator. An above ground rock
pad could be visually inspected, easy to clean, and has the potential
to develop vegetation and some bio—filtration.
I hope these items will clarify and release the SEPA and Shorelines
review.
Thankyou.
