Port Ludlow. 98365 WA SUBJECT: REVIEW OF PORT LUDLOW RESORT PLAN REVISION DRAFT SUPPLEMENTAL ENVIRONMENTAL IMPACT STATEMENT, JEFFERSON COUNTY, WASHINGTON Jefferson County Department of Community Development 621 Sheridan Street Port Townsend, WA 98368 Dear: Mr. Al Scalf 3 June 2004 The Port Ludlow Drainage District has reviewed the Port Ludlow Resort Plan Revision Draft Supplemental Environmental Impact Statement (DSEIS) dated April 2004. The Resort Plan Revision area described in the DSEIS lies entirely within the boundaries of the PLDD. The District submit the following comments: . 1. The Port Ludlow Drainage District is a public agency with SEP A authority and environmental expertise for surface water and drainage issues within the District. The PLDD should be included in all distribution of any SEP A documents developed for this and any prpject within or impacting the PLDD per WAC 197-11-455. 2. The SEPA Handbook (Publication #98-114) states on page 53 that "...the adoption form (of the original EIS] must be included within the draft supplemental EIS." The development regulation in Appendix A reference that adoption but does not include the adoption form (published October 1992 and April 1993. 3. Jefferson County and the PLDD have adopted the 2001 Washington State Department of Ecology Storm water Management Manual for Western Washington. Since the DSEIS is essentially a new application, the proposal must meet all applicable requirements at the time of application. Therefore, the currently adopted Stormwater Management Manual should be used for stormwater management. 4. The PLDD encompasses all ofthe proposed development. The District has prepared and adopted a Comprehensive Stormwater Management Plan (October 2003) which should be included in the environmental documents referenced and commented on by the DSEIS. 5. Short-term impacts from construction must be addressed for Temporary Erosion and Sediment Control (TESC). A TESC certified professional should be part of all construction inspection. LOG ITEM 1 of3 ",,, 6. The Ahernative 1: Preferred Project does include stormwater facilities for new development. To the maximum extent practical, the new facilities should address existing developed areas that may not have adequate water quality or quantity treatment. Examples of this may be use of treatment facilities such as oil/water separators for parking areas. 7. To the greatest extent practical, low-impact development methods should be incorporated into the development plans. Areas such as occasional or overflow parking should have specially designed pervious surfaces to allow for direct inftltration of storm water, separation of directly connected impervious areas, and bio-retention to the maximum extent practical. 8. Under Section 3.2. 1. I-Affected Environment, reference is made to stormwater discharge to an "artificial lagoon." Using the lagoon for storm water management, active maintenance would be anticipated. No such provisions are stated in the DSEIS. Additional detail for responsibility and operations and maintenance should be provided. Within the lagoon, settlement of suspended solids is included in one-water quality treatment mechanisms. However, no discussion is provided pertaining to the maintenance and operation of the lagoon. Is dredging anticipated ifso how often? Where would the dredge spoils be disposed? How will the lagoon be accessed? 0 (.) C1 ~ '.r= :z :::> ~ 0 I (.;) ~ z 0 ffi 9. u... tb ...., 10. Presently pumps circulate the lagoon water, these pumps consume considerable electrical power and require maintenance and eventual replacement. The DSEIS must discuss the future operation, maintenance and expenses incurred by the pump facilities. Liability issues pertaining to the lagoon must be discussed in this DSEIS and prior to start of construction, these liability issues must be fully resolved. Items such as the floating walkway over the lagoon, the unfenced lagoon, the integrity of the embankment separating the lagoon from the bay, algae blooms, etc. 11. The DSEIS does not provide any information on the water quality of the existing lagoon. Before proposing to use the lagoon for water quality treatment for stormwater flow, testing should be completed for the existing water quality ofthe lagoon. This will help determine if the addition of stormwater would result in an improvement or degradation of water quality for the runoffas well as of the lagoon. We recommend testing for fecal coliform, metals, salinity, hardness and pH in both wet and dry season. 12. The DSEIS does not specifically state the responsibility for drainage systems after construction is complete. The operation and maintenance of all installed drainage facilities must be clearly stated. With the additional private ' LOG ITEM #~ Page ;;l. of 3' . 2 ,. residences rather than a larger single complex, stormwater facilities and maintenance often are ignored until the point of failure. 13. The location of the proposed Admiralty III complex will require addressing both surface water runoff and groundwater. During the wet season, the groundwater is very close to the surface and it will impact any development or stormwater detention systems. We recommend that a geotechnical engineer or hydrogeologist licensed in the State of Washington be used to design the storm water and groundwater system in compliance with the 2001 Department of Ecology Storm water Management Manual for Western Washington. The Port Ludlow Drainage District was formed in year 2000 to address drainage issues within the greater North Bay. Since the formation, the District has developed a comprehensive plan that includes modeled flows, flow control, treatment, and maintenance for drainage facilities within the District. The District looks forward to working with Jefferson County and Port Ludlow Associates in addressing stormwater issues within the project area.
