The Beckett Point Fishermen's Club is a leasehold property, currently divided into approximately 165 leases within two legal tax parcels. The residences are currently served by individual on-site septic (OSS) systems. The existing systems are old and their condition and level of treatment is not well known. The Beckett Point Fishermen's Club wishes to eliminate individual OSS systems and establish a community sewage collection and treatment system, thus reducing the potential pollution to nearby surface and marine waters. The proposed project involves abandoning the majority of the individual OSS systems and construction of two new independent community sewage collection and on-site treatment systems. Several underground grinder pump stations will be installed on the sand spit and at the top of the slope in residential areas. The grinder pump stations will collect sewage from one to five lots and convey the sewage via shallow, small- diameter pressure pipelines to one of two central underground pump stations located near the base of the bluff. From there, sewage will be pumped to intermittent pump stations located on an existing shelf on the bluff and pumped again to new large underground septic tanks located in a forested area on the eastern portion of the property. Effluent will be pumped to large drainfields on the eastern portion of the property. Approximately 5 acres of forestland will be cleared for the septic tanks and drainfields. The drainfield area has been located at the furthest point possible away from the existing slopes above Beckett Point. Property Location: Beckett Point Fishermen's Club is located approximately six miles southwest of Port Townsend on the east side of Discovery Bay. It consists of two tax parcels. Parcel Number 0022~ Building Permits/Inspections Development Review Division 3 Lon9~~riJ~Ptatnfri~Y I ( FAX: (360) 379-4451 (360) 379-4450 includes the beach area where most of the sewage collection will occur. Parcel Number 002242003 consists mostly of the uplands and bluff area where the drainfie1ds will be located. Legal Description: Parcel Numbers 002 231001 & 002 242 003 in Sections 23 & 24, Township 30, Range 02 West, WM, Located on Beckett Point Rd, Port Townsend, W A 98368. Site Conditions: The subject parcels encompass approximately 84.08 acres. The beach area is a large sand spit with a tidal lagoon in the middle of the sand spit. The beach area is flat, with a steep bluff separating it from the drainfield area. The west-facing bluff is covered with thick grasses and shrubs and sparse fir trees and has slopes as steep as 70%. The north-facing bluff is covered with Douglas Fir trees and thick vegetation and has slopes as steep as 100%. The north and west bluffs are separated by Beckett Point Road, Surrounding Area: The parcels adjacent to the northern boundary of the subject parcels are zoned Rural Residential1:5 (RR 1:5) and Rural Residential 1:10 (RR 1:10). The surrounding parcels vary greatly in size from .16 acre to 12.18 acres. Access to this area is via Cape George Road to Beckett Point Road. Two county local access roads, Marrakech Circle (C616409) and Hillcrest Avenue (C616009) intersect Beckett Point Road providing access to the bulk of the smaller parcels in the area. The eastern and southern boundaries of the subject parcels abut Discovery Bay shoreline, Required Approvals: Compliance with the Jefferson County Comprehensive Plan, adopted August 28, 1998; and the Jefferson County Code, Unified Development Code, Title 18 JCC adopted December 18, 2000, and effective January 16,2001, Shoreline Management Master Program for Jefferson County, adopted March 7, 1989, integrated with the Jefferson County Code as Chapter 18.25 JCC, Shoreline Master Program, Jefferson County Code, Flood Damage Prevention, Chapter 15,15 JCC adopted November 20, 1995 and effective December 20, 1995.

Information available in the environmental checklist is not repeated in this document unless it is necessary to do so as part of staffs analysis. Proposed mitigation measures are underlined and numbered, NATURAL ENVIRONMENT EARTH: GEOLOGY AND SOILS: Development is proposed on lands characterized by steep slopes and mapped as slight, moderate and high landslide hazard areas. A geotechnical report prepared by Myers Biodynamics Inc. (Log Items 11 & 30) addresses the generalized subsurface conditions, hydraulic loading rates, water budget and groundwater nitrate loads and quantification of nitrate in groundwater. The geotechnical report states, "The proposed treatment system will result in an annual increase in groundwater input to the local system of less than 6 inches based on prior analyses of the wastewater treatment area (MBI May 2005). Due to the relatively minor estimated increase to the groundwater regime, it is our opinion that the input to the system will have a negligible adverse affect on slope stability." MLAOS-OOS20 Beckett Point Sanitary Improvements Page 3 of 11 _~_'f1'3<<- '~~:":"-:C'-"":',,,,,,,,,~,,,""",,._,"_~ ..""'i.".......",..,..'.""'_:"'.~". It further states, "In our opinion, the implementation of conventional erosion control techniques and best management practices (BMP's) during construction will mitigate the erosion hazard risk on the property." A summary of the geotechnical report recommendations are as the follows: Upland Area - Excavation can likely be performed using conventional equipment. For open cuts, the site soils would generally be considered Type A to B soils and can be cut to a minimum % to I horizontal to 1 vertical (3/4/ to IH:IV) based on the Safety standards for Construction Work, Chapter 296-135 WAC. If open cuts are not possible due to space limitations temporary shoring could be used. Shoring should be designed to support the granular site soils. We recommend an equivalent fluid unit weight of 35 pcf for soil in the upper 5 feet of the excavation and 25 pcf in the dense sand and gravel soils typically at depths greater than 5 feet. Beckett Point/Sewerage Alignment - Due to the loose nature of the site soils and groundwater, excavations will be subject to caving and sloughing unless shored particularly below groundwater levels, Where shoring is provided, we recommend the upper unsaturated soil zone be designed for an equivalent fluid unit weight of 35 pct. Below the groundwater elevation, a unit weight based on the combined soil and hydrostatic loading of 80 pcf is recommended. Above the groundwater level, open cuts could be used. Based on the WAC safety standards, the loose sand and gravel soils would be considered Type C soils with a maximum open cut of 1-1/2 H: 1 V. Where groundwater is encountered, flatter open cuts or shoring would likely be required. Structural Fill - To help reduce buoyancy forces during periods of elevated groundwater, seismic events and flooding, we recommend that fill placed around the proposed improvements including pump station and trench backfill (above pipe bedding) be placed as structural fill. Structural fill should consist of well-graded, granular material free of organic debris or other deleterious material. Structural fill should be at a moisture content to allow for proper compaction, Due to the primarily granular nature of the site soils, we anticipate that the majority of soils will be suitable for re-use as structural fill. In some locations on The Point, organic silt or clay soils are present. These organic silt or clay soils are not suitable for re-use as structural fill. If construction and fill placement are to occur during wet weather conditions or on wet subgrade soil surfaces, we recommend structural fill material be utilized that is suitable for wet weather construction. A suitable material is "Gravel Borrow" as presented in Section 9.13-,14 of the Washington State Department of Transportation (WSDOT) Standard Specifications for Road, Bridge, and Municipal Construction (Standard Specifications). However, the gradation should be modified so that a maximum 5 percent by weight of the material passes the U. S. No. 200 sieve as based on the minus %-inch fraction. Structural fill should generally be placed in lifts not exceeding 10 to 12 inches in loose thickness. Each lift should be compacted to a firm, non-yielding condition and to the minimum relative densities presented in the table below, Where hand or other lightweight compaction equipment is used, we recommend maximum lift thicknesses of 6 to 8-inches.

These structures should be designed to resist hydrostatic uplift forces. Uplift forces can be resisted by increasing the weight of the structure such as additional concrete mass incorporated into a pump station, holding tank, and/or thrust blocks. Additionally, soil backfill above buried structures. This assumes backfill is placed and compacted as structural fill. Drainage - Control of site surface water is an important risk mitigation factor for both erosion and landslide hazards. We recommend that the proposed site improvements include a drainage system to capture and direct surface water turnoff to suitable discharge 10cation(s) at the base of the steep coastal slope. This includes new access roads and other impervious surfaces in the treatment system area on the upland portion of the site. Collected water should be routed down the slope via the existing Beckett point Road swale, assuming adequate capacity is available, or via a separate drainage discharge pipe. Vegetation Management - The presence of established vegetation on the upland portion of the site and steep coastal slope helps reduce the risk of slope instability and erosion. Vegetation removes water from the shallow slope soils, helps to reinforce the shallow soils via live vegetative root systems, and intercepts incident precipitation. We recommend that vegetation be maintained on all portions of the site, except where required for the treatment system installation. This will help maintain the current site slope condition and help avoid adverse impacts to the steep coastal slope. Where construction activity requires clearing and/or disturbs existing vegetation, the areas should be immediately protected from erosion and revegetated as soon as possible following construction. The following item is requested as mitigation to avoid significant impacts due to this proposal: 1. The proiect shall comply with all recommendations within the geotechnical report prepared by Mvers Biodynamics Inc. dated June 16.2005 and any subsequent amendments or addendums to this report.

Alternatively, groundwater-monitoring wells could be installed near the perimeter of the site to monitor actual nitrate levels migrating from the project area in order to have an early detection system available to respond to potential changes in groundwater quality," The following item is requested as mitigation to avoid significant impacts due to this proposal: 8. Groundwater-monitoring wells shall be installed near the perimeter of the site to monitor actual nitrate levels migrating from the proiect area. Based on the applicant's compliance with the proposed mitigation, this proposal is not likely to result in significant adverse impacts to WATER. Additional analysis of the proposal and its effects related to WATER is not necessary. PLANTS AND ANIMALS: HABITAT: A wetland area exists in the interior of the sand spit. The proposal will not directly affect the wetland, however, a substantial portion of the project will take place within the wetland buffer. A wetland delineation prepared by Pacific Rim Aquatic Environmental Sciences dated August 5, 2000 and a Wetland Delineation Amendment prepared by Parametrix dated June 17, 2005 were submitted with the application. The wetland delineation classifies the wetland as a Category II wetland. Table 3-4 of JCC 18.15.340 requires a standard buffer of 100-ft. The wetland delineation amendment states: 9. Work areas at Becket Point will be restricted to existing improved areas. including the prism of Beckett Point Road. private driveways. and landscaped areas at homes to be included in the upgraded septic system. 10. Best management practices. including the use of sedimentation fencing. will be used to protect water quality for local area waters and the wetland during construction. 11. After installation ofthe force main and hookups for individual homes. disturbed areas will be graded to the pre-construction contour. Paved driveways and Beckett Point Road will be resurfaced with pavement. Disturbed vegetated areas will be reseeded in compliance with the Ecology stormwater manual. Environmentally Sensitive Area mapping identified saltwater marsh, bald eagle and blue heron habitat. Copies of the proposal were sent to Gretchen Lux with Washington State Department of Ecology. She made no comments. Copies of the proposal were sent to Washington State Department of Fish & Wildlife. Oral comments were received from Shelly Ament regarding bald eagle habitat stating that no eagle habitat management plan is required, however, she would like to keep as many trees as possible. Written comments from Jeff Davis with the Washington State Department of Fish & Wildlife stated, "The Great blue heron rookery has relocated from the Beckett Point slope to a wetland located on parcels 002242017 and 002242013.
