CEDAR 0 P.O.BOX 578• of 1864 �o -SHELTON WA 98584 • (206)427-9670 , FINDINGS FOR MASON ENVIRONMENTAL PERMIT DATE: October '27, 1994 PERMIT NO. : RLC54-1568 PROPOSED -ACTION: . Sand Hill Mini-Storage (Kirk Chafe) This Mason Environmental Permit will address the phased construction of. 52,,500 sq. ft. of commercial- storage space and caretaker area; permitting 2000 cu. yd. of grading, 'replacement of. existing �culvert across type 4 creek, and addressing runoff through stormwater,management. Comments 'from'',reviewing •departments` are as following: DEPARTMENT OF COMMUNITY DEVELOPMENT: From •several .site-,visits, staff observed a type- 4- stream and a very large , (greater than 25 acre) wetland•north 'of ' State Highway 300 and west of Sand Hill Road: Proposed devel-opment. will' need_ to -be setback from each -of these resource •values. These setbacks will in maintaining vegetation along the stream and wetland edge. Since 'thip proposal is commercial development, a portion of the developed, area shall be dedicated to parking; in- this case 3 or 4 spaces would be adequate. DEPARTMENT OF PUBLIC WORKS: County Hydraulic Engineer finds that the applicant's proposal meets county standards for stormwater runoff control . The project engineer (McCullough) submitted a Stormwater Report and Calculations which presents construction erosion control features. The County Hydraulic Engineer commented that these features should be incorporated into the conditions of the county's Land Modification Permit, including the minimum width of the detention pond berm for stability reasons. DEPARTMENT OF HEALTH (ENVIRONMENTAL HEALTH) : The applicant has not applied for a septic permit for the caretaker/office building. The soils in potential drainfield areas (to the west of the storage buildings) are known to be gravelly loamy sands on 5 to 15 percent slopes. The applicant expects that estimated septic system flows will be 360 gallons per day. FIRE MARSHALL: The applicant has not submitted the specific plans for the storage buildings. The Fire Marshall shall review such plans for fire flow adequacy and fire control systems (sprinkler, heat detection, or construction elements) when those plans are submitted with the county building permit (s) . COUNTY BUILDING DEPARTMENT: Once building permits are submitted, the County Building Department will review specifications to see if they conform with the building, energy, and fire codes of the county. CONCLUSIONS: Based upon the above comments, this Department finds that applicant has addressed the potential impacts to the nearby stream and wetland area. The site plan and the environmental checklist for the proposed development show that setbacks and stormwater control measures will minimize the impacts from the construction of this storage building project. The conditions attached, when implemented, will assure that impacts to the stream and wetlands are minimal. On this date, Mason Environmental Permit (RLC94-1568) is approved with the attached conditions. Allan Borden, Land Use Planner Gary LdOA, Di ctor Department of Community Development CONDITIONS FOR MEP APPROVAL RLC94-1568 KIRK CHAFE - MINI-STORAGE PROJECT 1) In placing the new culvert, the applicant will comply with the construction and post-construction standards established in the Hydraulic Permit Application approved by the Washington Department of Fish and Wildlife. These permit standards shall include minimizing water quality impacts to the stream crossed as the culvert is replaced. 2) The applicant shall establish temporary sediment and erosion control measures on site prior to commencing with the grading approved through a Mason County Land Modification Permit. These measures shall be effective until an approved stormwater water quality plan is implemented. Construction erosion and sediment control elements, detailed in the project engineer's Stormwater Report and Calculations (Pat McCullough P.E. , Oct. 3, 1994) , shall be implemented. 3) An approved permanent stormwater water quality plan shall be prepared in accordance with the DOE Stormwater Manual and approved by the Mason County Dept. of Public Works. This plan shall include detention ponds for infiltrating roof runoff and treating paved surface runoff. 4) The applicant shall apply to the Dept. of Ecology for coverage under the State Baseline General Permit for Storm Water Discharges Associated with Industrial Activities. Many of the elements of this Permit will be set forth in the permanent stormwater water quality plan stated above. 5) The applicant shall continue to manage the vegetation setbacks along the stream and wetland areas to protect the natural values of these critical resource areas. This shall be accomplished through a permanent open space agreement or Native Growth Protection Easement for the wetland, stream, and setback areas of this property and recorded with the Mason County Auditor' s Office within 45 days of permit approval . 6) The applicant shall locate the drainfield for all uses on this property at a location that provides the maximum distance setback from the stream, wetland and well areas. MASON COUNTY PUBLIC WORKS DIRECTOR/COUNTY ROAD ENGINEER Shelton, Washington 98584 October 20, 1994 INTER-DEPARTMENTAL COMMUNICATIONS DATE ___ _.__ TO: MIKE BYRNE, Building Dept. - General Services Director FROM: AI-AN A. TARTA, P/W - Hydraulic Engineer SUBJ: Sand Hill Mini Storage - Kirk Chafe Public Works review of the Kirk Chafe Mini Storage proposal located on the Sand Hill Road in Mason County finds the proposal meets County standards for stormwater runoff control. I have contacted Mr. McCullough,P.E., the engineer on the project about the detention pond construction, and requested that the top of the detention pond berm width be set at a minimum of 6 feet wide. Mr. McCullough agreed to make that change to the proposal. I have crudely calculated the earthwork volumes from the road profile sheet, and arrived at approximately 3,300 yards of cuts and fills. Half this would be 1,660 cubic yards which represents the road construction. Building site leveling and stormwater facility construction will increase this amount, so I would support a grading estimate of, 2,000 cubic yards on this project. The construction erosion control features offered in Mr. McCulloughs' Stormwater Report and Calculations dated October 3, 1994 should be incorporated into the permit as conditions. Erosion and sediment control features addressing construction activities are not portrayed on the drawings, but are covered in Mr. McCullough's verbiage in the stormwater report. AiM A.

The Administrator and/or Planning Commission may require the applicant to submit any additional information or material which is deemed necessary for an adequate review of the application. B. When four (4) or fewer mobile homes are to be located on an applicants land, the applicant shall submit a site plan as indicated in Appendix 1. This type of mobile home park shall be known as a small mobile home park, and may not have to go through the hearing process (section 4.01.010. (D) ] , but will need permit approval from the Administrator, and shall meet all requirements of this ordinance excluding those indicated. C. When five (5) or more mobile homes are to be located on an applicants land, the applicant shall submit an application and site plan as indicated in Appendix 2 . Mobile home parks of this nature shall comply with all regulations and requirements of this ordinance, unless otherwise specified. D. The Planning Department shall give notice of a public hearing by the Planning Commission. The notice of public hearing shall be given by publication of at least one notice not less than ten (10) days prior to the hearing in a newspaper of general circulation within the County. All property owners within three hundred (300) feet of the proposed project will also be sent notifications; provided, all small mobile home parks are exempt from this notification. The Planning Commission shall consider the application at its next public hearing and shall render a recommendation, or continue the hearing to obtain further information. The Planning Commission may recommend denial, approval or conditional approval of the application. Recommendations shall be submitted to the Board no later than fourteen days following action by the Planning Commission. Upon receipt of the recommendations on any mobile home park permit, the Board shall at its next public meeting set a date for the public 5 hearing where it may adopt or reject the recommendations of the Planning Commission. Approval of the application shall be effective for two years from the date of the approval by the Board. An applicant who files a written request with the Department of Community Development at least thirty (30) days before the expiration of the two (2) year period, shall be granted one one-year extension upon showing that the applicant has attempted in good faith to make substantial progress on the mobile home park within the two (2) year period. Requests for additional one (1) year extensions must be approved by the Board.

My primary "concern" in evaluating your request is trying to account for the considerable difference in the depths of your two wells. As you are aware, Well #1 is 80 feet deep, while Well #2 is 191 feet deep. The reason that this is an issue is that,in order include 2 or more wells on the same water right application,the wells need to be completed within the same water bearing formation. What would be most helpful would be if you can provide me with the actual locations for these wells,measured in feet from the nearest section corner, (For example 1000 feet west and 2,200 feet north of the southwest corner of Section 33),and the approximate elevations of each well site. I would also like to get a brief explanation of the reason for the depth differences — I've tried repeatedly to contact your driller, and am unclear why he extended casing from 42 to 191 feet through what is described as "sand and gravel with water" when the first well was completed at a much shallower depth in what appears to be the same material. Any light you could shed on the subject would be very helpful to me. Finally, I wanted to let you know that the withdrawal rate I will recommend for your water right permit needs to be based on the actual production capacity of your wells. So, while you have requested 125 gpm on your application,your well logs indicate that pump tests were conducted at rates of 45 gpm, and 40 gpm for a total capacity of 85 gpm. If you wish to pursue our authorization for a greater withdrawal capacity than 85 gpm, please send me pump-tests results that demonstrate that these wells are capable of pumping more water on a safe,sustainable basis. Thanks for your attention to these issues. While you may certainly call me directly at (360) 407-0274 to discuss this project,I'd like getting this information in writing so that it can be included in the formal record.

REPORT OF EXAMINATION DESCRIPTION OF PROPOSED WORKS 2 Wells DEVELOPMENTSCHEDULE BEGIN PROJECT BY THIS DATE: COMPLETE PROJECT BY THIS DATE: WATER PUT TO PULL USE BY THIS DATE: Started September 1,2001 September 1,2006 REPORT BACKGROUND: On December 6, 1996 Kirk Chafe filed Application for Water Right G2-29443 to appropriate public ground water from two wells. A withdrawal rate of 125 gpm was requested for multiple domestic supply. The project site is located within Water Resource Inventory Area 15—the Kitsap Peninsula,within the general boundaries of the Union River sub-basin. A public notice of the proposed appropriation was published in the Shelton-Mason Journal on November 25`" and December 2, 1999. No objections were received as a result of this notice. Based on the provisions of Chapters 90.03 and 90.44, Revised Code of Washington (RCU19, and the following information, I recommend issuance of a permit. INVESTIGATION: This application was filed with the intent of securing a water right to serve 61 mobile homes, and an I I-unit mini-storage facility. The project site is known as the Sand Hill Mobile Home Park Water System,and is located in Mason County on the Tahuya Peninsula. The community of Belfair is located about one mile to the east. The project is situated about a half mile north of Lynch Cove, the terminus of Hood Canal's easterly arm. The site encompasses the SE'/4 SE'/4 of Section 30,Township 23,Range 1 W.W.M.and elevation ranges from less than 20 feet at the southeast comer to about 110 feet at the northwest corner. The nearest surface water body is the Union River,which enters into Lynch Cove about 1,500 feet southeast of the well site. In consideration of this application, I reviewed the information submitted with this application,records of water rights and well logs on file with this department,and several other reports and hydrogeological assessments on the area. Chris Neumiller and I visited the site on November 19, 1999. Project Description The project is accessed off of Sand Hill Road,north of North Shore Road.The site is currently cleared and appears ready for mobile homes. This area is generally rural and largely undeveloped. Two wells have been constructed on the site. Well 1 was constructed in November of 1998, and is completed at a depth of 80 feet below ground level in a water-bearing zone of sand and gravel. The well flows under artesian pressure. Well 2 was constructed in December of 1998,and is completed at a depth of 191 feet below ground level. The elevation of both well sites is approximately 30 feet above sea level. Both wells are completed in advanced outwash material, beneath a layer of blue clay that is about 22 feet deep. The clay layer acts as a confining or semi-confining layer and both wells flow under artesian pressure. Despite the difference in completion depth the formation the wells are completed in appears to be water bearing,and no secondary confining layer is indicated by the driller's well report. The applicant proposes to construct a water system that will provide both domestic supply and fire protection to the project. The system will include a 66,000-gallon water storage tank and 6-8 inch distribution system. The instantaneous capacity of the two wells is 95 gpm. Union Sub-Basin The Union sub-basin is one of 18+sub-basins identified within Water Resource Inventory Area(WRIA) 15 (Kitsap). It covers an area of approximately 39 square miles in portions of both Kitsap and Mason Counties. The Union sub-basin's boundaries generally include the southern portion of Township 24 North,Range I West,and all of Township 23 North, Range 1 West, W.M. The geological characteristics of the sub-basin are similar too much of the surrounding Puget Lowland. The majority of the land surface within the sub-basin is comprised of a relatively broad,upland area(interpreted to be a Pleistocene glacial drift plain). The upland is bisected by a large remnant glacial outwash channel through which the Union River now flows. The uplands of the sub-basin are recharge areas for ground water. Recharge occurs primarily from precipitation falling on the land surface. The portion of precipitation that doesn't run off,evaporates,or transpires,percolates downward to saturate underlying water- bearing strata. Surface water bodies such as Mission Creek and the Union River receive discharge from shallow ground water systems that occur within the uplands. Much of the deeper ground water discharge is to Hood Canal. The town of Belfair is the largest population center in the sub-basin. In general,the sub-basin is characterized by scattered, small communities,small hobby farms, large lot rural tracts, and undeveloped forestland. Residential development is concentrated along the shoreline of Hood Canal. Surface Water The Union sub-basin contains a total of 12 recognized creeks and rivers, which have a combined drainage area of approximately 38.3 square miles. The largest streams within the sub-basin are the Uilion River and Mission Creek. Larger lakes include Tiger and Mission Lakes. Within the sub-basin the only large surface water diversion is the City of Bremerton's Casad Dam, located at McKenna Falls in the upper reaches of the Union River(River Mile 6.7). The City holds rights to 10 cfs,and the Union River diversion provides approximately 60 percent of the City's water. The lower Union River occupies a relatively broad valley that is developed with residential areas and farms. Mission Creek is located roughly four miles west of the Union River. Its drainage parallels that of the Union River,but the lower part of the creek has a much narrower valley than that of the Union River. REPORT OF EXAMINATION 2 No. G2-29443 Report'Continued Under the provisions of Chapter 173-515 WAC, instream flow regulations have been established for 18 locations within WRIA 15 (Instream Resources Protection Program—Kitsap Water Resource Inventory Area—WRIA 15). For the Union River,bi-weekly instream flows were initially established at River Mile 2.0. However,the river has subsequently been closed year-round to additional consumptive appropriations,from McKenna Falls to the mouth. There has been no active gauge at the site since 1959. Since 1956, flow in the Union River has been restricted by the City of Bremerton's Casad Dam and reservoir. Likewise, Mission Creek is also closed year-round to further appropriations. This restricted status on additional consumptive appropriations also applies to ground water in hydraulic continuity with closed surface water sources. Ecology will deny ground water applications that have the potential of impairing a closed or otherwise regulated surface water system. Regional Geologya Hvdrogeology The geology and hydrogeology of Kitsap and Mason Counties and adjacent areas has been described in a number of publications, including: Water Resources and Geology of the Kitsap Peninsula and Certain Adjacent Islands, USGS Water Supply Bulletin No. 18 (Garling,et al., 1965);Ground-Water Availability on the Kitsap Peninsula Washington, USGS Open File Report 80-1186(Hanson,A.J., and Bolke, E.L., 1980);Water Resources of the Gig Harbor Peninsula and Adjacent Areas Washington, USGS Open File Report 81-1021 (Drost, 1982);and the Gig Harbor Peninsula Ground Water Management Plan Task 5 Hvdrogeologic Evaluation Report,prepared for the Tacoma-Pierce County Health Department(Sweet-Edwards/EMCON, Inc., 1992). The March 1999 Robinson&Noble report titled, Union Subarea Initial Basin Assessment,strives to summarize those portions of previous work that pertains to this particular area. The assessment of the Union sub-basin is an extension of the Kitsap County Initial Watershed Assessment,Open File Technical Report No. 97-04(Kitsap County Public Utility District,et al.,October 1997). Up to six alternating periods of glacial and interglacial deposition over the past 1.6 millions years have created numerous aquifers and aquitards within the Puget Lowland. This history of glacial erosional and depositional events,separated by long periods of non-glacial erosion and deposition,has created a very complex sequence of unconsolidated sediments beneath the area. These unconsolidated sediments range in thickness from zero to over 3,000 feet. They cover an irregular bedrock surface of Tertiary age(50-55 million years old)that is exposed in the northern portion of the Union sub-basin in the Green and Gold Mountain highlands. There are several wells within the sub-basin that penetrate bedrock,but none are known to be major producers of ground water. While the hydrogeology of the Union sub-basin has not been studied in detail,the general hydrostratigraphy is similar to other parts of Kitsap County. The uppermost aquifers within the Union sub-basin include perched aquifers-generally considered localized and laterally discontinuous—although some are several miles in lateral extent. Beneath the perched aquifer system lies the Sea Level aquifer system, which generally occurs between 100 feet above and 200 feet below mean sea level. There are also several deeper aquifer systems within the sub-basin. Based on the potentiometric surface maps of the ground water system developed for other parts of Kitsap County the shallow ground water flow is generally from topographic highs to lowland areas. Within the Union sub-basin,this would be from upland areas toward stream valleys. For the deeper ground water systems(Sea Level and deeper aquifers),ground water flow is generally towards salt-water bodies. In the Union sub-basin,there is a potential ground water divide from which deeper ground water moves either north-northwest toward Sinclair Inlet or south-southwest toward Hood Canal. Studies conducted in other sub-basins of Kitsap County indicate that upper aquifers discharge to streams and lakes,while the Sea Level and deeper aquifers discharge largely to Hood Canal. Fisheries Habitat The streams of the Kitsap Peninsula all originate in lower elevation foothills and lack glaciers and snow pack to provide continuous melt in the summer. Since the streams draining this area are entirely dependent on rainfall,flows are lowest during the dry summer months. Limiting factors for fish production include seasonal flooding,low summer flows, intermittent debris or beaver dams and water quality problems. The Union River and Mission Creek are home to coho and chum salmon. Both rivers are productive coho streams. Chum salmon spawn in the lower 1.5 miles of Mission Creek,and to the falls at river mile 6.7 on the Union River. A small run of chinook also returns to the lower two miles of the Union River each year. Sea-water Intrusion Seawater intrusion is the inland movement of marine water into an adjacent coastal aquifer.Because the WRIA 15's numerous peninsulas are surrounded by Puget Sound and Hood Canal,most of the region lies within 2 miles from a shoreline and a marine water body. Therefore,seawater intrusion resulting from ground water extraction is a potential concern for a large portion of this region. For those wells that are completed below sea le-el ch as th! San,.-!

Pumping could also have a small effect on wells within a broader radius of the site,slightly increasing the risk of seawater intrusion. While there have been no previous reports of elevated chloride levels in the immediate vicinity,I recommend regular v:iater quality testing to unsure that levels do not increase. Neighboring Water Users A review of Department of Ecology records indicates 5 ground water certificates have been issued within an approximate half-mile radius of the subject wells. These water rights have been i,sued primarily for multiple domestic supply of residential developments and school facilities. Ground water certificates authorize the withdrawal of 555 gpm,and 547 acre-feet per year. There are also several surface water certificates in the area and they authorized the use of springs for commercial,industrial and single domestic supply. The nearest certificated water rights are appurtenant to the gravel operation immediately west of the Sand Hill Mobile Home Park site. There are numerous claims on file with the Department of Ecology,that full within this half-mile radius. The vast majority of the claims were filed on exempt wells for general domestic purposes,however a few claim the use of springs or the Union River itself for irrigation. Well log records for the area shows a variety of depths, this is due to the variation in elevation as the topography rises to the north of the site. For the 20 well driller's reports I located for this general area, 15 wells are completed at depths of less than 100 feet below ground surface,while 5 are completed at depths of greater than 150 feet. Several private domestic wells are located approximately 1,200 feet east nr•r­ ^r r v n,rn.r,,•ronto I .. ^ . Report Continued of the proposed Sand Hill Park wells,the nearest well is the Ace Paving well located about 500 feet to the west of the proposed well sites. The Ace well is 78 feet deep. There have been no reports of declining water levels or well interference in this area. Generally, this area is productive for ground water development because wells tap into the saturated zones below sea level. Given the depth of this well, the relative sparseness of well distribution in the area,and low water demand required to serve this project,I find that impairment of neighboring water users is unlikely. Water Demand The average daily water needs for residential supply of mobile homes in this area amounts to approximately 350 gallons per day\connections. The mini-storage facility equates to additional 11 lots for a total of 72 equivalent residential units. Water demand for domestic supply amounts to approximately 28.25 acre-feet per year. This includes adequate water for the limited irrigation of shrubs and landscaping. CONCLUSION AND FINDINGS: These well sites are located near the mouth of the Union River,and given the depth of the wells, static water levels, and the surface elevation, it does not appear that the wells will intercept water that would otherwise have discharged to restricted surface water bodies. While the Union River receives discharge from the uppermost water bearing zones,the Sand Hill Mobile Home Park wells are completed below sea-level,and it is not likely that their use will have any affect on the creek's base flow. In accordance with Chapters 90.03 and 90.44 RCW, I find there is water available for appropriation from the source in question, that the appropriation as recommended is a beneficial use,and should not impair existing rights or be detrimental to public welfare. RECOMMENDATION: I recommend that this application be approved and a permit be issued to allow appropriation of 95 gallons per minute from a well,28.25 acre-feet per year,for multiple domestic supply.The period of use is year-round,as needed. This permit is subject to the following provisions. PROVISIONS: The water appropriated under this application will be used for public water supply. The State Board of Health rules require public water supply owners to obtain written approval from the Office of Water Supply,Department of Health, 1112 SE Quince Street,PO Box 47890, Olympia,Washington 98504-7890,prior to any new construction or alterations of a public water supply system. An approved metering device shall be installed and maintained in accordance with RCW 90.03.360,90.44.450 and WAC 508-64-020 through—040,and WAC 508-12-030. Meter readings shall be recorded at least monthly. Installation and maintenance of an access port as described in Chapter 173-160 is required. An air line and gauge may be installed in addition to the access port. Water-pumpage and chloride levels shall be submitted each year in the month of January,or more frequently upon request,to Ecology's Southwest Regional Office Water Resources Program. The data shall be submitted in digital format and shall include the following elements: For Water Use Reporting 1. Measurement method(totaling meter,acoustic meter,etc.)for each well 2. Total volume pumped from each well by month in thousands or millions of gallons 3. Unique Well ID number For Water Quality Monitories 1. Unique Well ID Number 2. Sampling date and time 3. Chloride concentration(mg/L) 4. Submit paper copy of laboratory report "Permittee or certificate holder,and its successor(s)shall provide data on chloride concentrations for the well authorized by this permit or certificate with analysis performed by a state accredited laboratory. Accreditation information may be obtained from Ecology's Quality Assurance Program at(360)895-4649. Sampling shall occur in August of each year, with a copy of the laboratory results submitted by January 15 of the following year,to the Department of Ecology, Southwest Regional Office,Washington." "If pumping of the well authorized by this permit or certificate causes-Horide concentrations to exceed 25 milligrams per liter, immediate action shall be required to prevent concentrations from increasing(such as reducing the instantaneous withdrawal rate(gpm)of the well). If corrective measures fail to prevent chloride concentrations from exceeding said level in the future,permittee or certificate holder shall relinquish the option to perfect additional allocated quantities regardless of the stage of development." The applicant is advised that notice of Proof of Appropriation of water(under which the final certificate of water right is issued)should not be filed until the permanent distribution system has been constructed and that quantity of water allocated by the permit to the extent water is required,has been put to full beneficial use. A proof inspection will be conducted prior to final certificate issuance. The certificate will reflect the extent of the project perfected within the limitations of the permit. Aspects will include as appropriate the source(s),system instantaneous capacity,beneficial use(s), annual quantity,home services designed,place of use,and satisfaction of provisions.

Extension of mobile home permits (after the first one-year extension) must be approved by the Board. The permit was approved on January 3, 1996 and was good for a two year period. One year extensions may be requested by the applicant as provided in section 4.01.010 of the Mason County Mobile Home and Recreational Vehicle Park Ordinance. Extensions are based on a showing that the applicant has attempted in good faith to make substantial progress on the mobile home park. The first extension is to be approved by the Director of the Department of Community Development. Subsequent extensions are to be approved by the Board of Commissioners. According to Pat McCullough, representing Kirk Chafe, construction on the project has been continuing and was approximately 70% complete in August 2000. (Letter dated August 28, 2000) Mr. McCullough notes that water rights have been pending for four years. The applicant has also pursued Health Department approval for a large on-site sewage system. In 1996, after approval of the permit, Mr. Chafe applied of a water right permit. The Washington Department of Ecology (WDOE) is responsible for issuing water right permits. In a letter dated September 30, 1996, the WDOE indicated that it might be some time before Mr. Chafe's application could be processed. Approval was not issued by the WDOE until August 24, 2000. On file are three letters requesting extensions. The letter dated December 1, 1997 requests an extension to January 3, 1999. The letter dated December 1, 1998 requests two one-year extensions u�Wt 3, 2001. The letter dated August 28, 2000, requests an extension of the permit for an additional year, from January 3, 2001 to January 3, 2002. Unfortunately, the Department has been unable to locate any approvals or denials of the extensions requested. Based on the information available, in particular the known delays in permit review for water rights by WDOE, the Department would have approved the initial request. Subsequent requests.= may be approved by the Board based on the applicant's good faith effort to advance the project. PROPOSED MOTION I move that, based on the finding that the applicant has made a good faith effort to timely complete the project, the Board approve the requests of the applicant and extend the Sand Hill Mobile Home Park permit until January 3, 2002.

Box 578 Shelton, We. 98584 AUG 2 9 2000 Dear Allan, iwASON Co.PLANNING DEPT Kirk Chafe has asked that I request an extension of the Mobile Home Development Permit for the Sand Hill Mobile Home Park. The project was started on January 3, 1996 and has been progressing along through construction up to this time. Since the construction of the project was continuous and is now approximately 70% complete, Mr. Chafe was not aware that he needed an extension of the permit to complete the project. Items that have been completed on the project are. 1. All the engineering and planning work has been completed except%r the design and repast preparation for a Class A water system. Water Rights were applied for 4 years ago and we just recently received notice from Jill Walsh of the Department of Ecology that they were in the process of awarding water rights to the project. The development of a Class A water system would eliminate the need for the previously proposed"six pack"approach for supplying water to the mobile home park. The water wells have been completed and we expect the water rights to be granted within the next two months. 2. All the rough grading, final grading, and road grading has been completed for the entire project 3. The drainage system, including detention ponds has been installed and is operational. 4. The roadway and utilities have been installed for the first 12 mobile home lots. 5. The community septic system for the first 14 lots has been permitted and is under construc- tion at this time_ It is about half complete. The soils on the unpaved portion of the project are such that wet weather construction is fea- sible and we expect to complete the project this fall and winter. We request that a one year extension from this date be granted if an extension of the mobile home permit is required. Please contact me if you need any further information about the project.

An environmental impart statement (1sLs) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. 711e purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instructions for Applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EiS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as Zoning, shoreline, and landmark designations. Answer these questions if you can. if you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Use of Checklist for Non-project Proposals: Complete this checklist for non-project proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL ACTIONS (part D). For non-project actions, the references in the checklist to the words "project", "applicant", and "property or site" should be read as "proposal", "proposer", and "affected geographic area", respectively.

Proposed timing or schedule (including phasing, if applicable): It is proposed to construct a mobile home park in phases to meet the demand for mobile home spaces in the local area. The first phase will include 9 mobile home spaces. The park will be developed at the rate of approximately 10 spaces a year for the next 6 years. 7. Do you have any plans for future expansion, or further activity related to or connected with this proposal? If yes explain. The proposed 61 unit mobile home park will complete the development of this prop- erty. The existing wetlands will be left undeveloped. 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. Bob Wildermood of Wildermood and Associates of Port Orchard has prepared a wetland delineation study for the site. The wetland boundaries were surveyed by John Loritzen PLS of Northland Survey of Allyn after the boundary had been estab- lished by Mr. Wildermood. 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. No other applications are currently pending. 10. List any government approvals or permits that will be needed for your proposal, if known. A Class A water system is proposed and WSDOH will have to approve the plans. We will be using the Ace Paving well(60 GPM) located on the gravel pit to the West. Ace Paving has existing water rights for 272 gallons per minute for the purposes of washing gravel. We have contacted the WSDOE and they have indicated that a change of use should not be a problem. We will be sharing the new 64,000 gallon steel, water tank with Ace Paving. IL Give a brief,complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. Please refer to the enclosed Sand Hill Mobile Home Park Development Plan and Vicinity Map. All the information required to respond to this question is included on this drawing. We are planning to develop the remaining 15 acres of the 19 acres of uplands on the 38 acre parcel. The site has been surveyed and the boundary estab- lished by a land surveyor. A 5'topography map was prepared for the entire upland site based on field survey. A 2 foot contour map has been prepared of the mini storage site. This mobile home park will include a total of 61 lots plus a large recreation building. 11 of the lots will be set aside for elderly couples without children. The park is in- 3 tended to only allow new mobile homes. The owner intends to sell mobile homes at the site for placement on the lots. The majority of the existing site is heavily wooded with Alders and thick under- brush. The existing fir an spruce trees that are scattered around the site will be left in all areas except the drainfield sites. The alders and the underbrush will be re- moved(Alders constitute dangers trees to the mobile homes). The owner intends to landscape each lot as the development is constructed. The current landscaping plan calls for one large tree (10 to 15 feet high) and one small tree to be to be placed on each lot along with shrubs and grass. 12. What is the location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project,including a street address, if any,and section,township,and range, if known. If proposal would occur over a range of area,provide the range or boundaries of the she(s). Provide a legal description,site plan,vicinity map,and topographic map, if reasonably available. While you should submit any plans required by the agency,you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. See enclosed Development Site Plan and Vicinity Map. B. ENVIRONMENTAL ELEMENTS 1. EARTH: a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous and other. See the Preliminary Site Plan that includes 5 foot contours prepared by field survey. 35 acres of the site is flat to rolling terrain that is between elevation 15 feet MSL and 65 feet above MSL. The Northeast corner rises sharply to an elevation of 110 feet. The entire Southeast one half of the property is a wetland and will be preserved. b. What is the steepest slope on the site (approximate percent slope)? The steepest slope on the property is 30% in the Northeast corner. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. .• $:24fi ryW140. ...2' ••��y2•.�� °�d°j' FF `r :. ,Q.• Y• :��•.•:.• s „ t A; .:: off'. ... .:%jljnik.J::�: :4i� t I��j•.jr�^' S:.iY.!;`•.•s i?°�i%::,•'jsJ; �:i';l3l�2��?j2>i:,:,YR •6•;.jy•'•fi :fir•;;:i: 4 SOIL TYPES: Ee - Everett Gravelly Loamy Sand 5% to 15% slope. Ea - Everett Gravelly Loamy Sand 0% to 15% slope. lb - Indianola Loamy Sand Mh - Mukelteo peat, shallow overgravel, 0 to 2 percent slope. There is no prime farm land on the site. There is a large gravel pit owned by ACE Paving Co. on the West Side of the site. ACE Paving has infringed on this site in several locations along the West boundary. d.Are there surface indications or history of unstable soils in the immediate vicinity? If so,describe. There are wetlands on the site which include peat soils. We will not be working in the wetlands. e. Describe the purpose, nne,and approximate quantities of any filling or grading proposed. Indicate source of fill. The fill for the roadways and the mobile home pads will be taken out of the Everett, Gravelly Loam series on the West side of the site on the boundary of the gravel pit. The area where the soil is removed will be finish graded, covered with top soil and planted with grass upon completion of the excavation. It is estimated that about 3000 cubic yards will be excavated from this area for roadway and mobile home park construction purposes. The rest of the site will be graded by re-contouring the site with local soils which will involve cutting and filling approximately 2000 cubic yards of material. f. Could erosion occur as a result of clearing,construction, or use? If so,generally describe. Yes it could. The indianola series soils could be eroded in localized areas. However, because of the flatness of the site, the numerous local depressions, and the wetland buffers there will be little potential off site siltation of the wetlands and stream. Erosion control measures will be included with the final site plan. The two main storm water detention ponds have already been installed as part of the Mini Storage project that preceded this phase of the project. These ponds intercept most of the surface storm runoff from the site and prevent silt from reaching the wetlands. g.About what percent of the site will be covered with impervious surfaces after project constructions(for example,asphalt or buildings)? Approximately 11% of the entire site will be covered with impervious surfaces when the project is complete. h. Proposed measures to reduce or control erosion,or other impacts to the earth, if any: Runoff will be controlled with the existing local depressions in the land or con- structed siltation basins. The site will be hydroseeded when the grading is com- plete. Diking and buffers will be maintained around the wetlands to prevent intru- sion of silt laden waters. 5 2.AIR: a. What types of emissions to the air would result from the proposal(i.e. dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any,generally describe and give approximate quantities,if known. Dust will be controlled by spraying with water during dry periods. Construction of the site will occur over an extended period of time which will minimize construction activity. The portion of the site nearest the adjoining homes to the North will be developed last.There were no of site dust problems during construction of the 3.5 acre mini storage site. The mobile home park will generate approximately 300 vehicular trips a day when it is at 100% occupancy. This small amount of vehicular traffic will not cause any significant air pollution. The approximate development density of this parcel will be 2 units per acre if the wetland are included in the density calculations. The site will be less dense then the Plat of Beards Cove that is located to the North. Beards Cove does not cause any air pollution problems. b.Are there any off-site sources of emissions or odor that may affect your proposal? If so,generally describe. None. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Use water to control dust during construction. 3.WATER: a. Surface: 1)Is there any surface water body on or in the immediate vicinity of the site(including year-round and seasonal streams,saltwater, lakes,ponds, wetlands)? If yes,describe type and provide natnes. If appropriate,state what stream or river it flows into. There is small(1 cfs) stream that bisects the property. It flows from groundwater seeps above the property through the wetlands into the Union River Estuary. The entire Southeast corner of the site is wetlands. See the proposed development plan. 2) Will the project require any work over, in, or adjacent to (within 200 feet)the described waters? If yes, please describe and attach available plans. No, because the entrance roadway was completed as part of the mini storage project that proceeded this project. 3)Estunate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate Ow area of the site that would be affected. Indicate the source of fill iaterial. None. 4)Will the proposal require surface water withdrawals or diversions? Give general description,purpose,and approximate quantities if known. No. 5)Does the proposal lie within a 100-year floodplain? If so,note location oil the sit a l i G C q, &'o' 21 b0 L No. 6)Does the proposal involve any discharges of waste materials to surface waters? L) and anticipated volume of discharge. No. b. Ground: 1)Will ground water be withdrawn,or will water be discharged to ground water? Give general description, purpose, and approximate quantities, if known. Yes, it is anticipated that the project will use approximately 65 acre feet of ground water per year. The source of the ground water will be an existing deep well on Ace Paving's property to the West that produces 60 gallons per minute. We have made informal contact with the Beard's Cove water system managers and requested authority to join their system. We were told that they do not have enough water and that we could not join. 2)Describe waste material that will be discharged into the ground front septic tanks or other sources, if any(for example, Domestic sewage: industrial, containing the following chemicals. . .;agricultural, etc.). Describe the general size of the system, the number of such systems, the number of houses to be served(if applicable),or the number of animals or humans the system(s)are expected to serve. The waste water flow from the Mobile Home Park will be domestic sewage only. The average density of the park will be two bedroom homes that will generate between 100 and 240 gallons per day of waste water. State code requires that a flow of 360 gallons per day (3 bedroom units) be used for the design of septic systems that will serve areas that are not specified for elderly only. The Eastern 11 lots will be for elderly only. There are 50 pads with waste water discharge of 360 GPD and 11 pads with waste water discharge of 240 GPD. The system will be broken up into modules to allow for construction phasing of project. There will be 5 modules of 9 units that -9 8avrn will generate 3,240 GPD, one module of 11 units that will generate 2,640 GPD and one module consisting of 5 mobile home units and the recreation building that will - enerate 2 160 GPD. 9 �o �4V 1 v,naal�s The soil in the area is typically medium sand to a depth of 4 to 8 feet and very grav- elly sand and gravels below 6 to 8 feet. The ground water table was not encountered and is believed to be at a depth of approximately 15 to 20 feet below the site. The soils are Class 2 soils with an infiltration rate 1.2 GPD. The proposed waste water treatment strategy for this development is to use septic tanks and pressurized drainfield systems to treat the waste. (See enclosed drawings of the water and waste water systems) Each of the 6 modules us the elderIV mod- ule will include a 3,000 gallon primary septic tank, a 2,000 gallon secondary septic tank, a 1,500 gallon surge tank (with a timer) and two 120 foot long by 9 foot wide gravelless drainfield beds. The drainfield reserve will be between the beds (11 foot — — — — — — — — _ — — — -- — — — — — — — — — — — — — 3 ,.00,65.00 N i - aVo�+ nlf1 aNr•s I � m Q / XS,",5, � I k �f bJJ -IV 1 IV 7 I -V7B 7✓yZ✓"•� e°��L � J I a ILJ 1LJ If W ° ig fn8 rR� � II b •L1- oz II i 11 I If � II RI I ��v ' 0 6, = 1LJ iLJ IL Y�� ILJ fLJ I Z, t, IL I I I r- I I H I I J fh I _ T _ � I II_IJI M)3Nt o I'--1---1---I-'- -I---'-I-- 1---- -I --I- --F --I--T�. / I I i I I I I I I I i I h I 7 I V3ar U't3t3Mra0 I � I � I h I v3av Q1)vr+h'tlO I � ,6168z1 3 .86,Of.00 N 4ti �� tU1v�V�y3 1311S!D 3003 1Id 73AYHO ONIAVd 30V Q Z II """K3 dl]IS f0 3:103 10 -. - 1Id 73nVYO ONOVd 33V W o �WW a I I � o 0 w An LL F-(/)Z h spa _ 4 °C- - - Q I Q J -- -�- - - - - w � V J � > i w I U) w I O —1 Q w af I rl Q ~ � a I tl i if -1 LL) IL J IL J i III III $I I of Ir /fccQ 0 LU o I I I r 1 I f 1 1 I s �r [- v, -J I II �I II I II I II SII I �r w o w I II I II III M i n i II „I I I U) O ¢® ' I I I 1 1 1 II III Iii "I - � 1L J L J �L J �L J IL J IL J I --I I S I I —I S I I C I 5—rF5 �'131dNi- a� d QoZ I -PW Z� �O - ...�. _.l _ S�fl'Id S�11N.

Water Runoff(including storm water): 1)Describe the source of runoff(including storm water)and ntedtod of collection and disposal, if any(include quantities, if known). Where will this water flow? Will this water flow into other waters? If so,describe. Development of the 61 mobile home lots and the roadways to serve them will in- crease the impervious area on the site by a total of 3 acres. A preliminary storm water plan has been prepared and has been included with this document on the next page. Over 3000 feet of grass lined swales and ditches will filter the storm water prior to discharge into a large wet pond and dry pond detention facility. The 'dry pond has been constructed with a gravel filter dike to filter the flow from small storms before it enters the wetlands. A comprehensive storm water management report is being prepared using the new Mason County Storm Water Ordinance (un- der review) as a guideline. The quantity of flow released will be limited to less then the existing 2 year storm. The state drainage manual requires a release rate of 112 the existing two year storm where infiltration is not used to dispose or treat the storm water. Two factors mitigate the need to meet this criteria. The first is that this system has a direct connection to Hood Canal and the added detention is not nec- essary to protect stream habitat. The second is that the flow will be treated in grass swales and filtered before it reaches the wetland. Existing and proposed flows form the storm water runoff are shown below in Table 1.

NE 211 Sand Hill Road, Belfair; north of. the intersection of Sand Hill Road and State Route 300) ; SE1/4 SE1/4 Section 33 , T. 23 N. , R. 1 W. , W.M. IV. Project Description. Applicant proposes to develop a 61- space mobile home park on 15 acres of a 38 acre parcel; mini- storage area occupies an adjacent 3 .4 acres on this property. V. Description of Site and Vicinity. A. Characteristics of the site. Area of development is the north half of the 38 acre property, while the large forest/shrub- scrub/emergent wetland (19 acres) lies downhill to the south of the access road. The property is generally rolling topography of 5 to 10 percent, except at northwest corner and the north of the edge of the wetland area (south of the access road) . A type 4 stream flows from the north boundary of the property into the wetland. The soils on the property are gravelly loamy sands. B. Characteristics of the area. The property is bordered by State Route 300 on the south, with land fronting on Lynch Cove and Hood Canal located to the south of the road. Sand Hill Road borders to the east, with undeveloped land east of the road. Individual properties of the Beard' s Cove subdivision are situated on the north side of the subject property. An active gravel pit is on the large parcel to the west . VI. SEPA Review. A Mitigated Determination of Nonsignificance was issued on May 26, 1995 . Comments. were received from Mason County Fire Marshall, Department of Health Services, and Public Works Department; from Washington Department of Ecology, Sand Hill Elementary School, Mason County Historical Society, and Union River Basin Protection Association; and from letters from three residents and several telephone calls. SAND HILL MOBILE HOME PARK PROPOSAL 1 VII. Evaluations. Standards from Ordinance 118-91 (Mobile Home and Recreational Vehicle Parks, Art. IV) are used for evaluation. Section 4 . 01. 060 . Minimum Mobile Home Park Size. At 15 acres this site meets the 3 acre size criteria. Section 4 . 01. 070 . Mobile Home Space or Site Size. The site. size of 55 ft . by 90 ft . will allow the mobile home park to meet the setback and density requirements contained in the Ordinance. Section 4 . 01. 080 . Setbacks. A. Interior Roads . All sites meet the required minimum of 5 feet from right-of-ways . B. Exterior Site Boundary. Development will have 15 foot buffer from north, west and east boundary of property. C. Mobile Home Separations. Mobile homes will meet the standard of 15 foot setback between homes . D. Community or Service Buildings. A community recreation building (2500 sq. ft. area) is proposed in the center of the proposed park, where 15 foot setback will be met. E. Accessory structures. No accessory structures are currently proposed, but the site plan indicates sufficient room at each site to comply with the 15 foot required setback between mobile and adjacent structure should an occupant choose to construct an accessory structure. That location could be in the area between the mobile and the interior road or between adjacent mobiles. Section 4 . 01. 090 . Density. At 61 units on 15 acres, the density approximates 4 units per acre ( .25 acres/unit) , which meets the allowable standard of 7 units per acre. Section 4 . 01. 100 . Revegetation. No specific revegetation plan has been submitted,. but the applicant would meet this standard when erosion control by hydroseeding is done in disturbed areas, landscaping is done throughout the park, and natural vegetation buffers are left along the perimeter and stream-wetland areas. Section 4 . 01. 110 . Park Administration. The owner will assume responsibility for park maintenance as a condition of permit approval . Section 4 . 01. 120 . Road Standards. A. Maintenance of interior roads and their access for emergency vehicles shall be a condition of permit approval . SAND HILL MOBILE HOME PARK PROPOSAL 2 C. Proposed paving of interior road with asphalt meets paving requirement. D. Proposed 40 foot right-of-way for interior road meets requirement. E. Proposed two way paved road width of 23 feet meets roadway width requirement. F. Approach to county road will require a Road Access Permit Upgrade and must meet specifications required by the Mason County Public Works Department. The applicant has proposed to work with the county to provide turn lanes as part of a future road improvement project. Section 4 . 01. 130 . Parking. A. Based upon the site plan, there appears adequate room on each site for the two required spaces. (See Conditions) . B. The applicant has proposed 21 additional spaces (nine by twenty feet per space) within the park for guest parking, which exceeds the standard of 15 spaces required. Section 4 . 01 . 150 . Water Supply. With final approval of the water system by the Mason County Health Services Department, the water supply system will be in accordance with all applicable laws and standards. In addition, the applicant has proposed an on-site septic system for the mobile home park composed of six community drainfield modules for groups of 9 or 11 mobile home sites and one module of 5 mobile home sites and a recreation building. The effluent will be collected in septic tanks, pumped to the drainfields and distributed under pressure. This system shall be permitted and approved by Mason County Health Services Department prior to construction of each portion of the mobile home park. Section 4 . 01 . 160 . Lightinct. Low level security lights around the park, as proposed, will meet the Ordinance standard. Section 4 . 01. 170. Utilities . The proposed water, electrical and communication lines are to be buried, an ordinance requirement. Section 4 . 01 . 180 . Buffers. Recreation and Open Space Requirements . B. Buffering and screening: The applicant has proposed to maintain a 15 foot natural vegetation buffer for the north and east boundary, a 65 foot vegetation setback adjacent to the stream and wetland, and a fence along the east, north, and west boundaries . SAND HILL MOBILE HOME PARK PROPOSAL 3 C. Five percent of the gross area for open space and recreational use: Roughly 5, 000 square feet of open space is proposed in the west portion of the park, in addition to the 18 . 7 acres of wetlands. that occur on the south half of the property. This equates to roughly 51 percent of the property. The use of the area by pets and application of fertilizer should be restricted to protect the area water quality and resource values . The area will be open for access by members of the park to use as a community area. Section 4 . 01. 190 . Drainage and Storm Water Requirements. A/B/C. The Mason County Public Works Department determined that the drainage, detention and erosion control facilities have been sized to control and treat stormwater from the proposed mobile home park development. (See Conditions) . D. Drainage easements . The surveyed setback boundaries from the natural stream drainage will be maintained by the owner in perpetuity. Section 4 . 01.200 . Sensitive Areas/Unstable Lands . A. 100-year floodplain. N/A. B. Wetlands. The boundaries of the 18 . 7 acre wetland on the south half of the property have been delineated and plotted with adequate vegetation management and development setbacks on the mobile home park site plan. C. Unstable soils, geologic hazards . None on site. The base of the steep slopes on the northwest corner of the property will be levelled and used for drainfields only. Section 4 . 01.210 . Fire Protection. A/B/C. This proposed mobile home park has been reviewed by the Mason County Fire Marshall, and recommendations were included in the site plan. (See Conditions) . Section 4 . 01 .220 . Surveys . A survey of the site was submitted at the time of the mobile home park application. IX. Conclusion. Staff find the proposal consistent with the Mobile Home Ordinance and recommend approval, subject to the following conditions: Conditions 1 .
