Johnson Cc: Peg Staeheli Subject: Peer review comments on draft EIS Outline and 4 Technical Reports Hi, David — Attached you will find a memo with comments on the draft outline of the Supplemental EIS for the Pleasant Harbor proposal, and a memo from SvR addressing the technical reports for Grading and Drainage, Golf Course BMPs, Water Quality, and Groundwater. Review of water supply and wastewater technical reports from Bill Persich has not yet been completed; I'm sending these along because I thought you'd rather see them now than wait for everything at once. I'm heading out on vacation tomorrow, back at the end of next week. I should be able to pick up email during my vacation, however, so feel free to send me emails and I'll try to respond promptly. Thanks! - Lloyd Lloyd Skinner, AICP Senior Vice President j Northwest Regional Director ESA Adolfson 5309 Shilshole Ave NW, Suite 200 Seattle, WA 98107 206.789.9658 / 206.789-9684 fax (skinner@esassoc.com r ESA 5309 Shilshole Avenue NW www.adolfson.com Suite 200 Seattle, WA 98107 206.789.9658 phone 206.789.9684 fax memorandum date August 5, 2009 to David Wayne Johnson from Lloyd Skinner subject Pleasant Harbor Review of Draft Outline of EIS We received the draft outline of the Pleasant Harbor Marina and Golf Resort Master Planned Community Supplemental Environmental Impact Statement at the July 20 site meeting. The outline is very helpful in anticipating how the project impact analysis will be put together for County and public review. I have several comments and suggestions for the draft outline for the County's consideration. Treatment of each element of the environment. I see from the outline that each element of the environment is followed by an italicized comment referring to one or more Board of County Commissioners conditions. I recommend that the discussion of each element of the environment include a standard SEPA-style discussion of the site's existing conditions, a discussion of the probable impacts of each alternative, and a discussion of possible mitigation measures to address impacts identified. If the discussion then moves to an assessment of how the proposal complies with the relevant condition(s) adopted by the Board of County Commissioners, I think that would be fine. I would just caution that the outline as drafted implies that the discussion under each element of the environment would ONLY address compliance with the BoCC condition(s). In my mind, that would fall short of the complete discussion expected for a project -level EIS. Construction impacts. I do not see a reference in the outline to construction impacts. Construction impacts can be addressed within the discussion of each element of the environment (the impacts discussion is divided into "construction" and "operations" sections), or alternatively a separate Construction Impacts section is prepared for an EIS. For this large-scale construction project, the assessment of construction impacts will be an important consideration. Issues such as construction phasing, extent of disturbance by phase for staging, clearing, grading, and facility construction, and control of stormwater, traffic, and dust, for eample, should be addressed. It might make more sense for a construction project of this scale to include a separate construction impacts section. Description of the Proposal and Alternatives. The outline lays out the main sections of the EIS well. As a minor comment that does not relate to EIS adequacy, to reduce the number of sections in Part 2.0, Description of the Proposal and Alternatives, I suggest that we combine sections 2.2 through 2.6 (Location, History and Background, The MPR Proposal — Principal Features, Proposed Zoning Ordinance, and Proposed Development Agreement) into a single section, with these issues becoming sub -headings. Technical Reports. Peg Staeheli/SvR has prepared comments on four technical reports; these are attached to this memo. Bill Persich/Brown and Caldwell has not yet completed his review of technical reports; I will forward his comments shortly. DESIGN COMPANY MEMORANDUM #01 DATE: August 5, 2009 TO: Lloyd Skinner, AICP ESA Adolphson FROM: Peg Staeheli, ASLA Amalia Leighton, PE RE: Review of Technical Reports Prepared for SEIS Pleasant Harbor Master Planned Resort — Peer Review SvR Project No. 09025 This memorandum is to summarize our review of the following technical reports prepared for the Pleasant Harbor Master Planned Resort Supplemental Environmental Impact Statement (SEIS): 1. GRADING AND DRAINGE: Pleasant Harbor Marina and Golf Resort — Grading and Drainage Technical Engineering Report DRAFT, Prepared by Craig A. Peck & Associates, September 4, 2008 2. GOLF COURSE BMP: Draft Report Golf Course Development and Operation Best Management Practices Plan, Brinnon Master Planned Resort, Prepared by GeoEngineerings August 18, 2008 3. WATER QUALITY: Water Quality Monitoring Plan, Brinnon Master Planned Resort, Prepared by GeoEngineerings August 18, 2008 4. GROUNDWATER: Water Supply and Groundwater Impact Analysis — Draft Hydrologic Analysis, Pleasant Harbor Marina and Golf Resort, Prepared by Subsurface Group, LLC November 20, 2008 During the review of the documents provided project area limits and layouts were inconsistent. We recommend that when all draft reports are revised the same project limits and descriptions are provided with a reference date. These documents were reviewed to identify if information was provided to meet the items Civil Engineering listed in the Jefferson County Board of County Commissioners Conditions to be Met and Landscape Architecture documentation shown in the SEIS. SvR reviewed Section 3.3.1 Surface Water and 3.16.3 Environmental Restoration Stormwater Management. Planning • a — The Grading and Drainage report does not reference Jefferson County Code in the text, but it is apparent that preliminary designs use the 2005 1205 Second Avenue Department of Ecology Stormwater Manual for Western Washington. Suite 201 Stormwater runoff and treatment facility sizing calculations are included in the Seattle, WA 98101 appendix. Calculations were made using the required Western Washington Hydrology Model software. Phone: 206.223.0326 . q — It is unclear from the existing calculations if the development will be able Fax: 206.223.0125 to meet the requirements of zero discharge. Grading and Drainage report does svr@svrdesign.com not summarize the 300 page appendix containing the stormwater management facility sizing calculations. A table identifying the following information for Memorandum #01 - Review of Technical Reports Prepared for SEIS ' Pleasant Harbor Master Planned Resort — Peer Review August 5, 2009 Page 2 of 3 each basin should be provided: 1) total basin size, 2) proposed impervious, 3) proposed pollutant generating impervious, 4) proposed grass, 5) proposed pasture/native, 6).proposed forest, 7) predeveloped (forested condition) runoff flow rate, 8) developed flow rate, 9) average infiltration over basin area, 10) proposed type offlow control facility, 11) estimated size offacilities to meet forested conditions/zero discharge to Hood Canal, and 12) what stormwater treatment will be provided if any. In addition, it is does not appear that the existing sub -basin boundaries are being maintained. Proposed development information lists more proposed basins than the number of existing basins identified in Figure B.1. Additional comments specific to the organization of the report are provided below. r — A Draft Water Quality Monitoring Report has been prepared identifying monitoring approach, locations, and parameters. However, it is not identified who will be responsible for the monitoring and reporting during the various phases of construction and who will take over the monitoring when construction is complete. y — A Draft Golf Course Best Management Practices (BMPs) Plan has been prepared. BMPs are generally discussed. Specific BMPs need to be assigned that will be employed after construction that will meet the stormwater requirements in the 2005 Department of Ecology Stormwater Manual for Western Washington. Definitive language should to be used. In addition, SvR has the following general comments and questions following the review of Grading and Drainage Report. 1) Section 1.1 — Pre developed and Existing Conditions descriptions combined 2) Section 2.2 — Proposed development description does not include land cover values for each section of development 3) Section 2.2 — Proposed Development section (2.2) only describes the first phase approach. No other information is included for subsequent phases in Section 1 or for work in Section 2 and 3. 4) Section 2.4 - Potential Construction Impacts: a) No discussion how wetlands will be protected during gravel process b) No figure identifying limits of gravel process. Limits identified in plan do not seem to match scale of earthwork described in the report. More detail needs to be provided. c) Stockpiling areas "multiple stockpiles of wood debris approximately 25 feet high and 100 feet in diameter will exist for each area cleared" were not identified in the report. Areas cleared are not quantified. d) No discussion of impacts during construction of Section 2 and Section 3. 5) Section 2.5- Mitigation measures for construction impacts during phasing are not identified. 6) Section 2.6 — Only Phase 1 development is discussed 7) Section 3.1 — Existing Conditions a) Site specific drainage basin predeveloped and existing condition runoff peaks and volumes are not identified for the existing basins b) Runoff/Infiltration/Groundwater — This paragraph is not consistent with data presented in the Subsurface Group 2008 Report. Potential evapotranspiration for the site was calculated to be approximately 24 inches (Page 3 of 22). Memorandum #01 - Review of Technical Reports Prepared for SEIS Pleasant Harbor Master Planned Resort — Peer Review August 5, 2009 Page 3 of 3 8) Wetlands — Wetlands are going to be used to provide retention of stormwater prior to infiltration to meet flow control requirements of the proposed development. General sizing information including stormwater runoff volumes contributing to the wetlands should be included. Calculations need to indicate if the created and/or enhances wetland areas are adequate to meet the stormwater management requirements. 9) Rainwater Harvesting — Address if rain water harvesting is feasible considering that aquifer recharge is providing water supply for the development. 10) Reducing the Quantity of Stormwater to be infiltrated — See comment 9 above. 11) Report does not outline how the proposed development will meet the minimum requirements outline in the 2005 Department of Ecology Stormwater Manual for Western Washington. Most information is included it is just not organized well. 12) Phased Development - A proposed stormwater layout for each phase and the developed condition was not included. It is unclear what the stormwater management will be for Sections 2 and 3 during construction and when the development is complete. 13) WWHM results should be summarized in the text for each basin. 14) No discussion of sub -basin limits changing from existing conditions to the proposed sub -basin limits. 15) Report does not reference Jefferson County Code requirements. 16) Report does not reference FEIS Mitigating Conditions for subsequent project review, technical comments, and comment log. The following reports would also be useful in identifying information required of the SEIS: • Sequencing Plan for Construction Activities including phased development earthwork management plan and temporary and erosion and sediment control. • Arborist Report to identify tree information including tree retention, tree harvesting, and understory health to support stormwater calculations and temporary erosion and sediment.
