Dear Carolyn:
John Eliason at the state asked us to get Dave Salzer, Jerry
Houth and Gary Yando to sign a letter saying that our road
easement/drain field arrangement with neighboring property owners
was satisfactory. These were to be sent to you. I have talked to
each of them and they have agreed so you should be getting a
letter from each of them soon. I just wanted you to be aware of
what these are when they come in.
i
Hopefully this will put us close to getting our building permit!
Sincerely Yours,
4q-'7

APPENDIX B DATA SHEETS
I. INTRODUCTION:
The Stretch Island Fruit facility is located North of and
adjacent to State Highway No. 3 approximately 2 miles South of
Allyn on a 2.24 acre site. The project site is situate in the
Northeast Quarter of Section 21, Township 22 North, Range 1
West, Willamette Meridian in Mason County, Washington (Figure
1) .
The property is currently developed with a single-story, 6200
square foot fruit processing plant, and gravel parking area
covering the southern one third of the property. The remainder
of the property is typical Puget Sound second growth timber
stands of Western Red Cedar, Alder, and Maple. The under
growth consists of Salal and Fern (Figure 2) .
Based on soils investigations of the site it is determined
that the soils are a Hydrologic Group C (Figure 3) .
The proposed improvements for this project include a 5895 SF
Office/Warehouse Building, an expanded gravel parking area,
and associated storm drainage improvements. The project will
utilize on-site sewage disposal system.
A future expansion is also anticipated, which would include a
9,000 SF building addition and associated parking. To
eliminate a more costly "retrofit" process, the storm drainage
detention/wetpond and control structure will be sized to
include that future expansion (Figure 4) .
II. UPSTREAM ANALYSIS:
An upstream analysis of the project site reveals that
approximately 0.60 acres of forested land directly across
State Highway 3 contributes runoff to the site from the East.
The offsite runoff crosses SR 3 through an existing 12" CMP,
and flows along the South property line for approximately 350
feet to an existing depression on the site. The depression
drains back to the Southwest corner and ultimately over a
steep bank to the West. This off-site runoff will be conveyed
through the property in the final design and is therefore
omitted from the calculations.
III. DOWNSTREAM ANALYSIS:
A site investigation reveals that runoff discharges from the
site at the Southwest corner as described above as well as the
Northwest corner. Both routes discharge over a steep bank to
the West and into an unnamed creek. The unnamed creek
discharges to Sherwood Creek which runs North through Mill
Pond to its final discharge at North Bay (Figure 6) .

IV. DESIGN CALCULATIONS
r �
A. PARAMETERS:
1. DETENTION SYSTEMS
The WaterWorks software (Ver. 2.0) by Engenious Systems,
Inc. is used for design of the storm drainage facility.
The 2, 25, and 100-year storm frequency intervals will be
evaluated using the SBUH Method for this analysis.
■ Water quantity control for the increased runoff
will be performed by a storm water detention
wetpond designed to meet the discharge requirements
for one-half the pre-developed 2, 25, and 100-year
peak discharge release rate with a 2, 25, and 100-
year developed inflow.
■ Runoff for the 2, 25, and 100-year storm events
shall be computed using the SCS-based hydrograph
method, Santa Barbara Urban Hydrograph (SBUH) ,
given a Type 1A rainfall distribution.
■ Water quality control will be achieved by utilizing
a 160 t LF biofiltration swale at the outfall of
the detention system. The biofiltration swale is
sized for water quality using a peak 25-year pre-
developed discharge rate, and for capacity using a
peak 100-year developed discharge rate.
Additionally, 1/2 foot of dead storage will be
added to the detention volume.
■ Technical data will meet the requirements of
the King County Surface Water Design Manual
and using HYD.EXE hydrograph software.
2. CONVEYANCE SYSTEMS
Due to the limited catchment area involved, and the
utilization of ADS N-12 piping throughout, a minimum 12"
pipe size will be sufficient.
The biofiltration swale will be designed based on the
following:
Water Quality ► S = 2.00%, n = 0.24
Capacity ► S = 1.25%, n = 0.07
2
t �
A. PARAMETERS CON'T:
3. TRAVEL TIME
Travel time (T2) for the SBUH Method will be determined
as follows:
T2 = ( 0.42(n, * L)o.e / R2)0.5 * (8
o)0.4 ) +EL / (V*60)
where:
P2 = Design Storm, IN.
L = Flow Length, FT.
V = Velocity, FPS = k * (so)lie
n, = Manning's sheet flow roughness coefficient
(Figure 7)
s, = slope, FT/FT
B. DETENTION FACILITY DESIGN:
1. EXISTING CONDITIONS
EXISTING ON—SITE AREA, Am
ASX = 2.24 ACRES
Impervious ► AjNp = 0.67 ACRES
Pervious P. ApzRv = 1.57 ACRES
(See Figure 2)
ON-SITE OVERLAND FLOW DISTANCE, L.,
(See Figure 2)
L, = 501, S, = 158 - 157.7 / 50 = 0.06 $
L2 = 2501, S2 = 157.7 - 145 / 250 = 5.08
L, = 180' , S2 = 145 - 144 / 180 = 0.56 %

DEVELOPED CURVE NUMBERS
AR ► 0.16 Ac @ CN = 82 ► Lawns and Landscaping
2.08 Ac @ CN = 92 ► Gravel, Paving and Rooftops
3. DETENTION WETPOND:
The detention wetpond will be constructed with a bottom
width of 6 feet and a bottom length of 97 feet. The pond
will have 3: 1 sideslopes with 0.5 feet of dead storage
and a maximum design storage depth of approximately 3.25'
plus one foot of freeboard.
The required pond volume based on the WaterWorks design
calculations is 6, 125 CF. The live storage provided by
the proposed detention/wetpond is 6, 120 CF (99.9%) .
See attached Data Sheets Appendix B for Detention/Wetpond
design calculations and Control Structure design.

B. DETENTION FACILITY DESIGN CON'T. :
4. CONTROL STRUCTURE
The Control Structure for the Detention/Wetpond will be
a Triple-Orifice, Type II, 54" diameter catch basin with
a solid locking lid (See N.L. Olson Drawing No. for
Control Structure details) . Orifice sizing and elevations
are shown below.
Orifice Number Elevation Diameter
1 (2-YR Event) 145.16 3-1/16"
2 (25-YR Event) 145.83 7-9/16"
3 (100-YR Event) 146.22 OVERFLOW

5. BIOFILTRATION SWALE
The Biofiltration Swale is designed for both water
quality and capacity. Water Quality is determined using
the QZ = 0.41 CFS, while Capacity is determined using Q100
= 3. 12 accommodate the 100-yr overflow.
WATER QUALITY
Using a 2-Foot bottom width and 3:1 side slopes, the
biofiltration swale is adequate at 0.37 Ft depth.
(See Data Sheets, Appendix B)
CAPACITY
Again, using 2-Foot bottom width and 3:1 side slopes, the
biofiltration swale is adequate at 0.62 Ft depth.
(See Data Sheets, Appendix B)
Use a 2-FT bottom width, 3:1 side slopes,` and a minimum
depth of 2.0 FT to provide a minimum 0.5' of freeboard.

RE: STRETCH ISLAND FRUIT EXPANSION ( JOB # 4408-93 )
Dear Alan:
Enclosed are 3 copies of the revised plans and 1 copy of the storm
drainage maintenance requirements for the above referenced project.
As we discussed on the phone on 3-16-94, we have added a 4 ' high
chain link fence around the detention pond per you letter (dated 3-
14-94) . Additionally, I added a cross section of the pond to better
illustrate the dead/live storage elevations. This cross section
shows the difference between the 6' pond bottom shown on the plans
and the 8' pond bottom used in the storm drainage analysis.
A second sheet was added for general notes and details to help the
contractor and client understand the construction and maintenance
requirements for this project.
I have provided the client with a copy of the maintenance
recommendations from the Washington State Department of Ecology's
Stormwater Management Manual for the Puget Sound Basin for his use
in operating and maintaining the storm drainage facility.
If you have any questions or require additional information, please
call.

Grace and Don,
I have reviewed the revised Stretch Island permanent stormwater control plan
with revision date 3/16/94 and ffa satisfied that they have addressed the
concerns raised in my Marcell 14 , letter to theme and that their proposal meets
our present requirements for stormwater control from ccavercial
establishments. They are providing Puget Sound Water Quality Authority
dawnstream Erosion Control protection and PSWQA water quality treatment to
their discharge. The facility as proposed is sized to accxminolate the future
expansion as depicted on their proposal.
Attached please find two of the three final Storm Drainage Plans submitted to
Public Works for review with revision date 3/16/94.
Also attached is a copy of the cover letter that accagpanied these plans. I
did not receive the single copy of the storm drainage maintenance requirements
alluded to in their cover letter. 'Their cover letter indicates that they were
providing their client with a copy of DOE's maintenance re=mwidations.
Perhaps they didn't have a maintenance manual or instructions prepared at the
time they submitted these plans. A maintenance schedule should be provided
that binds the owner to maintaining the completed facility in some pre-
prescribed functional condition along with the frequency of inspections.
If I can be of any further assistance, call me at extension 461.

SUBJ: SAGERSON / STRBTM ISLAND FRUIT ADDITION
Don,
I have been in contact with Kim of Olsen & Associates, the Engineering firm
preparing the stormwater facilities for the Stretch Island Fruit Ccapany
expansion concerning an Operation and Maintenance Agreement for the ccupleted
stormwater features. Kim has provided the awner, Ron Sagerson, with a copy of
Kitsap County's operation and maintenance agreement. Because of the wording of
the document that requires maintenance of the existing and approved (approved
by county inspection and acceptance) facilities, Kim proposes that the O&M
document be recorded once the facilities are ccupleted and accepted by Mason
County. This sounds reasonable to me and I indicated to Kim that I would send
your department an IDC indicating that I feel their proposal is acceptable.
Final inspection of the Capitol improvements should include inspection of the
ccnpleted stormwater facilities to check their adherence to their proposal,
followed by recording of the O&M agreement.
Kim will be mailing me a copy of the O&M agreement that they plan to use, and
I will deliver a copy to you when I receive it. Essentially it will require
that the facilities be maintained in a functional condition with a provision
that Mason County will be egmwered to remedy any deficiencies and any
incurred costs will be cxmpensated by the owner.

Re: Building permit; office/warehouse - -drainage, erosion control
Dear Mr. and Mrs. Sagerson:
We have received comments from our Public Works Department
regarding the drainage and erosion control system for your proposed
expansion. That department requests additional information, as
follows.
The only stormwater features or information found for the proposal
are incorporated into the site plan. A Storm Control Pond is
shown, but no dimensions or elevations are given. A Control
Structure is shown on the site plan, but no details of its
construction or function are provided.
Details for the stormwater control facility should be provided
showing how the facility controls the developed runoff to pre-
development levels and how dead storage detention is provided to
infiltrate a Puget Sound Water Quality Control Storm Event (defined
as 64W of a 2 year 24 hour storm event) . Calculations, supporting
data and assumptions. used in the sizing and design of the facility `'
should be submitted.
An Operation and Maintenance Plan should be prepared by the I
proponent specifying the frequency of inspection and to what
standard the facility should be maintained.
A Sediment and Erosion Control Plan should also be prepared and
implemented for the site during the construction of the
improvements. The Technical Specifications provided with the site
plan allude to an E&S Plan being installed as shown on the plans,
but no erosion and sediment control features have been incorporated
into the plans submitted.
If you have any questions regarding these requirements contact Alan
Tahja at (206) 427-9670 x461. We will continue processing the
permit through the system while awaiting the above information.
Thank you.

follows.
r
The only stormwater features or information found for the proposal
are incorporated into the site plan. A Storm Control Pond is
shown, but no dimensions or elevations are given. A Control
Structure is shown on the site plan, but no details of its
construction or function are provided.
Details for the stormwater control facility should be provided
showing how the facility controls the developed runoff to pre-
development levels and how dead storage detention is provided to
infiltrate a Puget Sound Water Quality Control Storm Event (defined
as 64% of a 2 year 24 hour storm event) . Calculations, supporting
data and assumptions used in the sizing and design of the facility
should be submitted.
An Operation and Maintenance Plan should be prepared by the
proponent specifying the frequency of inspection and to what
standard the facility should be maintained.
A Sediment and Erosion Control Plan should also be prepared and
implemented for the site during the construction of the
improvements. The Technical Specifications provided with the site
plan allude to an E&S Plan being installed as shown on the plans,
but no erosion and sediment control features have been incorporated
into the plans submitted.

Don,
This afternoon I visited the Stretch Island Fruit Facility located near Allyn
to verify completion of the stormwater facilities.
The items enumerated in my June 13, 1995 IDC are all complete and satisfactory
with the exception of the permanent stabilization, ie, hydroseeding.
I received a letter from Mr. Ron Sagerson of Stretch Island Fruit, Inc.

improvements a
In June, Mr. Sagerson requested that the hydroseeding er has be delay until ed wisdom he his
weather turned more favorable. The recent
request, and I feel comfortable in relying on the 0AM Covenant as, a surety
that the seeding will be performed. Further confidence lies in the fact that
some of the denuded areas are already starting to recover and re-vegetate
themselves on their own.
In summary, I feel the Stretch Island Fruit, Inc. expansion facilities have
satisfied Public Works concerns and can be given final approval from the
Public Works Department.
