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) . 1 T I 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.

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. 4 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 RISER & . EMERGENCY SPILLWAY 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. 5 APPENDIX A FIGURES WA E v�i 4 .h O � �;•o:: Kd•'s�'. •'i:• , �� ( " 1 a/96 4go 4 70 �. j n e I i'Roc 5 �'!lse4 .as nmo 69 N ..

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.

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.

TAMA, Office Tech. - P/W 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. tr k AI A.
