Each building (4-plex) has an individual septic tank and drainfield system. In addition, 4 covered parking spaces (attached to northernmost building) and 30 uncovered parking spaces are shown (note: 5 parking spaces at end of road- way are not usable due to need for 60' diameter cul-de-sac for emergency vehicle access). Ingress and egress will occur to the north of the site via a 20 foot wide road. Of the 2.98 total acres, approximately .5 acre is unbuildable due to steep slopes. Gross density is approximately 8 units per acre and net density (buildable area) is approximately 9.6 units per acre. Domestic water and fire flows will be provided by the Belfair Water District. z Description of the existing environment: The site: The project site is heavily wooded and undeveloped. The topography is gradually sloping from east to west with the exception of the eastern corner which is relatively steep (12 to 25%). On the western edge of the site, which faces the commercial highway frontage, is a steep cutbank which was created by recent grading activity. This bank ranges in height from 8 to 15 feet. The soils on site are glacially deposited Everett type (gravelly sandy loam) which have slight limitations for development, although they do percolate rapidly. Existing vegetation is a typical mix of coniferous and deciduous trees and- undergrowth. There are mixed stands of cedar, Douglas fir, alder, and madrone with undergrowth of salal, Oregon grape, braken fern, huckleberry and kinnikinnick. +4 i Adjacent environment: The area around the site is a mix of commercial, residential, and forestry uses. Located near the "downtown" Belfair area, the predominant land uses near the site are commercial. The commercial facility adjacent to the site houses a convenience store, a restaurant, a clothing store, a tavern, and other uses. South of the site is a boat sales and storage business, a fast food service, ' and a real estate office. Residential units are located across S.R. 3 and adjacent to the site are two conventional single family residences and a mobile home. The remaining adjacent property is wooded and undeveloped. State Route 3 is a major regional arterial connecting Mason County to.Bremerton and Kitsap County. Average traffic volume on this highway is 5,500 vehicles .per day, with most vehicles travelling at or above the posted 55 mile per hour limit. i -4- Analysis of environmental impacts: (1) Earth - The proposal will disrupt, displace, and compact soils for construc- tion of roads and buildings. Some alteration to existing topography will occur as a result of grading for roads and buildings. The potential for erosion of soils will increase greatly during construction and decrease after project completion. In addition to erosion from grading and construc- tion, the cutbank at the front of the property will continue to erode during periods of rainfall. This problem could be accelerated by new construction i activity on the project site and by the addition of water from septic systems t into the soils uphill from this area. f (2) Air - There will be an incremental decrease in ambient air quality due to in- creased levels of auto emissions. Provision of fireplaces could also have an impact on existing air quality. (3) Water - Construction of roads and buildings will significantly reduce the amount of absorption area and increase surface water run-off. Of, the 108,900 square feet of buildable area, 33,600 square feet will be covered by impervious surfaces (approximately 30%). P6tentially adverse off-site impacts could re- sult from this increased run-off. { The soils of the site have rapid percolation rates. Injection of large volumes of waste water into a small area could deteriorate ground water quality. It should be noted that the drainfields for the shopping center are located at the base of the cutbank, immediately adjacent to the site. (4) Flora - Construction of the proposed project will require clearing of existing vegetation. This action will substantially reduce the number and diversity of species of flora on site. In addition, some new species could be introduced for landscaping. (5) Fauna - Changes in the number and diversity of species of fauna are considered to be minimal due to proximity of the site- to human activity and the fact that the site is fenced on several sides. Field observation indicated the presence of several common bird species. New species of domestic fauna could be intro- duced by new residents. (6) Noise - Noise levels on and around the site will increase as a result of the proposal. These impacts will be most significant for the single family residences adjacent to the proposal. Off-site noise generated by the adjacent shopping center could have adverse effects on the proposed residential units. (7) Light and Glare - Additional residences and vehicular movement will produce new light and glare. As stated earlier,' this impact will be significant for the single-family residents. Off-site light and glare generated by the shopping center (particularly the tavern and the convenience store) could have adverse effects on the proposed residential units. (8) Land Use - The Mason County Comprehensive Plan designates this area urban resi- dential and community shopping. The proposed development appears to be in con- formance with the policies of the Comprehensive Plan and is in character with the mixed commercial and residential uses in the area. The site is served by public water and most private and public services are within a very short dis- tance. Present land use trends in this area indicate continued strip commercial -5- development along State Route 3. This development proposal is located on the northernmost end of the "strip" and could accelerate the trend in this direction. The impacts of individual.commercial and multi-family develop- ments on traffic movement, public services, etc., are cumulative and, in sufficient concentration, could create serious problems for the future. As indicated by the proponent, additional development of this type to the north of this site is being contemplated by both himself and others. (11) Population - The proposal will result in increased population density in the Belfair area. It is estimated that the development will house about 65 people when all units are full. (12) Housing - The proposal will provide 24 new rental units in the Belfair area. This is considered to be a beneficial impact due to a severe shortage of rentals in this area. Projected rents will be between 200 and 300 dollars per month. (13) Transportation/Circulation - The proposal will generate between 150-200 trips per day. The indicated parking available (30 uncovered spaces and 4 covered spaces or 1.4 per unit) will not be sufficient for residents and visitors. This could result in a demand on existing parking at .the adjacent shopping center. The most substantial impacts will be on State Route 3 at the proposed ingress/egress point. In addition to increased usage of this road, the com- bination of poor sight distances and high speeds will pose serious hazards to motorists. (14) Public Services - The proposal will require additional public services. With the exception of schools, the Belfair area should be able to provide these services with little difficulty. (16) Utilities - Most utility systems will require only minor alterations (highway to property) to service the proposal. New systems will be required for septic tanks and drainfields and storm water drainage. Mitigation of Adverse Environmental Impacts The following measures could be implemented to reduce or eliminate potential adverse impacts: (1) Earth - During construction, temporary catch basins should be installed to retain run-off on site. Septic tank drainfields should not be located close to the cutbank. Health Department regulations require that .drainfields be set back 15 feet plus the height of the cutbank from the edge of the bank. This setback and vegetation or planting on the slope would maintain the integrity of the bank. (3) Water - Construct a surface water drainage and retention system capable of retain- ing all additional run-off produced by new impervious surfaces on site. (6) (7) Noise, Light and Glare - In order to reduce the impacts of conflicting uses (commercial-residential) some type of buffer should be provided along the common property line. This buffer could be a board type fence, site screening vegeta- tion, or some combination thereof. In. addition, a buffer should be provided between the proposed road access and the adjoining single family home. -6- (13) Transportation/Circulation - (A) To accommodate residents and visitors, the proposal should include a minimum of two (2) parking spaces per unit (required by.Mason County Ordinance 815). (B) At the end of the proposed development a 60 foot diameter cul-de-sac will be required for general and emergency vehicular turn around.. (C) Ingress/egress to S.R. 3 will be subject to the approval and design requirements of the State Highway Department. . (D) Sidewalks should be constructed from parking areas to units and from the site to the adjoining commercial facility. Adverse Impacts which cannot be Mitigated: (1) Earth - Disruption, displacement and compaction of soil. Alterations to existing topography. (2) Air - Minor decrease in ambient air quality. 3 (4) (5) Flora/Fauna -Reduction in number and diversity of species of both flora and fauna. (6) (7) Noise, Light and Glare - These impacts will occur; however, provision of adequate buffers will substantially. reduce this impact. (11) Population - The density of this area will increase as a result of this proposal. (13) Transportation/Circulation - Due to the present function and usage of S.R. 3, traffic hazards will increase as a result of the proposal. (14) Public Services - Increased loads on fire and police protection, schools, parks, roads, and other services will be generated by the proposal. (15) Utilities - Some minor alterations will be required to service the proposal. Recommendation: Based on this environmental assessment, site inspection, and consultation with the proponent, the staff recommends that a proposed declaration of non-significance be issued subject to the following conditions which will mitigate adverse impacts: (1) Use of temporary catch basins during construction to reduce soil erosion and run-off. (2) Design and construction of a Thurston-Mason Health District approved sewage treatment system. (3) Design and construction of a surface water drainage and retention system to the satisfaction of the Mason County Engineer and the State Department of Highways. -7- (4) Design and construction of roads, parking, and walkways to the satis- faction of the Mason County Engineer, the Mason County Planning Department, and the State Department of Highways. ( 5) Design and construction of. a landscape plan which provides a minimum ten ( 10) foot buffer of native or other site screening vegetation on all property lines. In addition, this plan should include sloping and planting of the cutbank along the northwest property line. (6) If any of the improvements listed above are not completed prior to appli- cation for a non-exempt permit (Mason County Building Permit), the proponent shall supply financial surety, satisfactory to the Mason County Prosecuting Attorney, for the completion of those improvements listed above before a non-exempt permit will be issued. -8-
