King County Consistency with a previous Board of Architectural Review approved design (L97- 0032). City Of Tukwila Analysis of Significant Project Impacts on Environmental Checklist Part B (Elements of the Environment) A SEPA Mitigated Determination of Non - significance was issued for the original gas station development ((E97- 0015). Impact mitigation related to protecting potential archaeological resources during excavation for underground fuel storage tanks. \ \TUK2 \VOL3\ HOME \VERNON \99 \costcogas \SEPASTF ADDENDUM.doc SEPA Addendum to Threshold Determination Staff Report E97 -0015: COSTCO Gasoline Station Page 3 An additional traffic study has been submitted to address concerns raised in the pre - application meeting and in subsequent meetings with the Public Works Department. The traffic study reaffirms the previous estimate of no impacts to the public road system. Should congestion significantly impact the public road system, then the City may re- evaluate its project approvals and require impact mitigating actions. The proposed 875 square foot gasoline station canopy addition with one pump island, to the existing 2,300 square foot, three pump island facility, various on -site circulation and landscaping revisions, and the addition of two turning lanes within the existing paved private roads, was evaluated for substantive impacts to the environment. The proposed development is shown in attachments A through G. The proposed project revisions are not anticipated to substantially change the impacts or alternatives which were evaluated in the previously issued Mitigated Determination of Non - significance. The sole mitigation condition regarding archaeology would not apply, since all improvements would be above the level of historic soil. Environmental review relies upon existing regulations to mitigate or avoid environmental impacts. Please note that existing regulations will require that the following concerns be addressed in the construction permit application: Surface Water 1. A copy of a King County Industrial Discharge Permit if putting surface water into the sanitary sewer, 2.- Drainage plans shall show the existing and proposed storm water system for the entire site (including the COSTCO Optical building area, all existing parking areas, and the gas station area), 3. methods for protecting surface water from excavation impacts, and 4.. consideration of the 100 year flood backwater when determining the elevation of structures. Traffic 1: plans shall show existing and proposed signage, striping and channelization for the entire site (including the COSTCO Optical building area, all existing parking areas, and the gas station area). 2. the Public Works Department presents the following recommendation for your consideration in further resolving traffic congestion on the private roads serving this project. These recommendations are made to help reduce the potential for impacts on the public road system. Such impacts would be the basis for initiating City review and requiring impact mitigation. These recommendations are not project requirements. a. provide a left turn lane on Saxon Drive with widening as necessary, b. installing a traffic signal at the intersection of Christensen Road and Saxon Drive, and c. modifying gas station circulation to eliminate cross - traffic for vehicles entering the site (possibly with separate ingress and egress driveways). \ \TUK2 \VOt.3\ HOME \VERNON \99 \costcogas \SEPASTF ADDENDUM.doc SEPA Addendum to Threshold Determination Staff Report E97 -0015: COSTCO Gasoline Station Page 4 Plants 1. All landscape planter islands with trees shall have a minimum six foot width for consistency with the Board of Architectural Review approved parking area design (L97- 0032). Lighting may need to be reoriented and parking restriped to incorporate this design. SEPA Action: The proposed addition to the gas station and site circulation improvements are determined to be minor in nature, especially as they occur in an existing paved environment. The above analyses and submitted information "does not substantially change the analysis of significant impacts ... in the existing environmental document." (WAC 197 -11 -706). Therefore, an Addendum to the COSTCO GAS STATION SEPA Mitigated Determination of Non - significance (E97 -0015) is herewith issued pursuant to WAC 197 -11 -625 (procedures) and 706 (definition/criteria).

As directed, the proposed changes have been "clouded in" on the original development submittal. Costco requests you review the submitted site plan and the Shoreline Substantial Development Permit Application. You have indicated that the process will also include amending the previous design approval. As directed by the city, Costco conducted an extensive traffic survey which included Washington State data. The recommended traffic mitigation measures have been incorporated into the submitted plans. These traffic mitigation measures as well as other site improvements include: • Moving the ingress driveway on Saxon 50' south in order to create additional stacking room for vehicles using the Costco Gas Station. Along with changes to the interior parking lot, this will allow adequate stacking room during peak usage times without vehicles backed up onto Saxon Drive. ■ Creating a right turn lane southbound exiting the Costco Warehouse parking lot at the intersection of Christensen Drive and Saxon Drive. This will alleviate some of the congestion and impact on this intersection. • Moving the egress driveway exiting the Costco Optical Center and /or the Costco Gasoline Station approximately 75' east on Christensen Drive. This will allow easier vehicle exiting both east and west bound onto Chritensen Drive. The aisle leading to this driveway has maintained a 25' width. Also, as directed by the Public Works Department, we have designed and shown an oil /water separator connected to the sanitary sewer. The landscape ratio on site has been maintained and the plan includes a warming hut for inclement weather. Z .• w -I 0: 'U O CD o W=! J 1— w O a: 1 W. .z �. O: zi—. 2 :;D :C1 .= w' I- V!

Mitigation Costs 14 ) INTRODUCTION This report documents the traffic impact analysis performed for the proposed expansion of the existing Costco Gas Station located in Tukwila, Washington. The expansion proposes to increase the number of gas pumps from 12 to 16. The following report documents the trip generation estimate, trip distribution, and traffic impacts for the proposed gas station expansion. The proposed expansion will be completed by fall of 1999. The existing Costco Gas Station is located south of Saxon Drive and east of Andover Park East (figure 1). The site is adjacent to the Costco Optical Lab parking lot (figure 2). The James Christensen Pedestrian /Bicycle Trail and the Green River are adjacent to the site on the east side. The most direct driveway leading into the site is Saxon Drive, which provides access from and to Andover Park East. Saxon Drive is currently a private road primarily serving the existing Costco Wholesale Store and Optical Lab. This driveway is signalized at its intersection with Andover Park East. The gas station also has access via Christensen Road from South 180th Street by driving through the Home Depot parking lot. The existing Costco Gas Station consists of 12 gas pumps. An additional four pumps are being proposed. There are no other vending facilities planned for the gas station. It is designed as a fully automated operation. The gas station in Tukwila is only available to Costco members —a non - Costco member cannot get fuel at the station, even at a slightly higher rate. There are no "new" attractions planned for this expansion. Therefore, the trip generation of the Costco gas station is not necessarily expected to increase. In fact, the intent of the expansion is to accommodate existing traffic to the gas station in a more efficient manner. However, to be conservative, it was assumed that the additional four pumps would generate new trips. EXISTING CONDITIONS Road Network The major access streets to the proposed Costco Gas Station site are West Valley Highway, South 180th Street, and Andover Park East. West Valley Highway (SR 181) is a five -lane north -south principal arterial with two through lanes in each direction and a two -way left -turn lane. It provides a link to the west Kent area south of the project site and northeast Tukwila north of the project site. It also provides a connection to the City of Renton via its interchange with Interstate 405 (1 -405). South 180th Street is a five -lane east -west minor arterial with two through lanes in each direction and a two -way left -turn lane. This roadway provides a major connection from Tukwila's central business district to the West Valley Highway and Kent.

U N` O� z Andover Park East is a four -lane north -south collector arterial with two through lanes in each direction and left -turn pockets at the critical intersections. It serves as an alternative northbound route to West Valley Highway. It is also a potential route to 1 -5 via Southcenter Boulevard and Tukwila Parkway and to 1 -405 via Southcenter Boulevard. Traffic Volumes Entranco performed turn movement counts at the intersections of South 180th Street/Sperry Drive, Andover Park East/Saxon Drive, and South 180th Street/Andover Park East during the weekday noon and p.m. peak hours, and the Saturday peak hour. In response to the City of Tukwila, internal Costco and Home Depot traffic patterns were examined at the intersection of Saxon Drive /Christensen Drive. These counts were performed on January 12, 13, 14, and 16, 1999. Internal traffic patterns were observed on January 30, 1999. Figure 3 shows the existing weekday noon and p.m. peak -hour and Saturday peak -hour traffic volumes on the primary access routes in the study area based on Entranco's counts. TRAFFIC VOLUME FORECASTS Trip Generation The City of Tukwila requested trip generation estimates for the weekday noon and p.m. peak hours, and Saturday peak hour. There are no "new" attractions planned for this gas station; the intent of the expansion is to accommodate existing traffic to the gas station in a more efficient manner. The additional pumps are projected to decrease queues at the existing gas station. Therefore, the number of trips to the Costco gas station is not necessarily expected to increase. However, to be conservative, it was assumed that the four additional pumps would generate new trips. Typically, trip generation rates used to estimate the number of new trips from a gas station are obtained from the Institute of Transportation Engineer's (ITE) Trip Generation Manual, 1997 Update to the Sixth Edition. However, due to the unique characteristics of a Costco gas station, the trip generation for the proposed site was based on trip generation rates from the existing Costco gas station at this site. A survey was conducted at the existing Tukwila Costco gas station between January 12 and 16, 1999. The survey data is located in Appendix A. The following data were collected: • Number of gas station transactions during the Saturday, weekday noon, and weekday p.m. peak hours. W:\ 98118 \Reports \CtukTIA (3/16/99)/kb 4 z _- w 6 U0 co w.

The trip generation rates are given as trips per gas pump. 2. Pass -by and internal trip reduction percentages were obtained from the survey of existing Tukwila Costco patrons. The average weekday p.m. peak -hour trip rate is 18.50 trips per pump. When the p.m. peak -hour trip generation rate is compared to the ITE Trip Generation Manual rate (14.56 trips per pump), it is shown that the Costco rate is higher (and therefore more conservative) than the ITE rate. This existing trip rate is lower than the 22.31 trips per pump projected in the original July 1997 traffic impact study for the Tukwila Costco gas station. The average weekday noon peak -hour trip rate for the Tukwila gas station is 20.16 trips per pump. The average noon peak -hour trip rate is higher than the average p.m. peak- W:\96118\Reports \CtukTIA (3/16/99) / kb 6 hour trip rate. The existing weekday noon peak -hour trip rate is slightly lower than the 21.88 trips per pump projected in the original July 1997 traffic impact study for the Tukwila Costco gas station. The Saturday peak -hour trip rate for the Tukwila gas station is identical to the weekday noon peak -hour trip rate at 20.16 trips per pump. The existing Saturday peak -hour trip rate is slightly lower than the 24.57 trips per pump projected in the original July 1997 traffic impact study for the Tukwila Costco gas station. The survey asked gas station patrons if the trip to the gas station also included a visit to the Costco Wholesale Store, which is defined as an internal trip. This information was divided by the total number of gas station trips to determine the percentage of internal trips. Internal trips are not considered new trips. Based on survey data collected at the Tukwila Costco, it was found that on average, 41 percent of p.m. peak -hour patrons using the gas station also go to the wholesale store. During the weekday noon peak -hour, 48 percent of gas station patrons also go to the wholesale store. During the Saturday peak hour, 50 percent of gas station trips are internal. These rates are shown in table 1. The total trips generated by a project can sometimes be reduced by a pass -by trip factor. Pass -by trips are defined as trips made as intermediate stops on the way from an origin to a primary trip destination. Pass -by trips were counted as part of the survey at the existing gas station. The pass -by trip percentages were calculated by dividing the number of pass -by trips with the total number of gas station transactions. Based on the survey data collected at the Tukwila store, the percentage of gross project - generated trips classified as pass -by trips during the weekday p.m. peak hour for the gas station is 43 percent; it is 34 percent during the weekday noon peak hour; and 28 percent during the Saturday peak hour (see table 2). The average trip generation rates and internal trip percentages were used to estimate the number of net new trips associated with the proposed expanded Costco gas station. Table 2 shows the trip generation for the four additional pumps at the Tukwila Costco gas station. Accounting for internal and pass -by trips, the net new trips generated by the expansion of the Tukwila Costco gas station in the weekday noon peak hour is estimated to be 14 trips. The net new trips generated during the p.m. peak hour is 12 trips. The Saturday peak hour is estimated to generate 18 net new trips.

This signalized intersection is the primary access point for the proposed gas station to and from the City's network. In addition, the City requested that the operations of the South 180th Street/Andover Park East, the South 180th Street/Sperry Drive, and the Saxon Drive /Christensen drive intersections also be analyzed. A LOS analysis was conducted using the principles of the Highway Capacity Manual, through a computer software package, SIGNAL94. The concept of LOS is to rate intersections operationally based on the average stopped delay per vehicle traveling through the intersection. The LOS of an intersection is ranked from "A" (low delay) to "F" (delay exceeding 60 seconds per vehicle). The LOS concept is discussed in greater detail in Appendix B. The proposed gas station expansion is scheduled to take place by fall 1999, the same year that the traffic counts were obtained. Therefore, no growth factor was added to account for increases in traffic volumes in the area. The results of the LOS analysis are presented in table 3, with LOS calculations presented in Appendix C. The LOS conditions currently experienced at the three City intersections range between LOS B and LOS C. The additional traffic volumes added by the four gas pumps only slightly increase intersection delay, and the LOS conditions remain unchanged, with a maximum 0.6 second per vehicle increase in the intersection average vehicle delay. On -Site Level of Service Table 3 also presents the LOS results for the unsignalized private intersection of Saxon Drive /Christensen Drive. Table 4 summarizes the queues for this intersection. On weekdays, this intersection operated satisfactorily. However, during the existing Saturday peak, this intersection operates at LOS F. According to the LOS calculations, the 95th percentile queue is estimated to be 14 vehicles (350 feet) on Saxon Drive. Saturday peak conditions were field verified on January 30, 1999. Queues of up to 11 vehicles were observed on Saxon Drive. Queues over 8 vehicles on Saxon Drive blocked access to the existing Costco gas station, and there were frequent blockages of the driveway. In addition, the queue at the gas station pumps was observed to extend into Saxon Drive, blocking the eastbound lane. Eastbound traffic had to go into the opposing lane to get around the queued vehicles. W:\ 98118 \ Reports \CtukTIA(3 /18/99) /kb ;' . ......�....... 10 z f-w re 6 V' o o. CO w• O �Q co n.

Gas station egress was also examined during the field visit. The gas station exit is approximately 100 feet from the intersection of Saxon Drive /Christensen Drive. Whenever the northbound queue reached four vehicles at the intersection, the left -turn movement out of the gas station was unable to access Christensen Drive. The northbound queue was observed to extend to four vehicles several times during the January 30, 1999 site visit. Based on calculations, the additional gas station trips from the proposed four gas pumps did not affect weekday LOS or queue lengths. However, on Saturday, the four additional trips through the intersection caused the LOS to be incalculable using the HCM methodology. This indicates that the intersection is operating at capacity, and no additional vehicles may be added without causing excessive delays.

One of the real intents of adding additional pumping stations is to serve gas station patrons more efficiently, and reduce the waiting times and queues for gas. The new pumps may mitigate the existing queues at the gas station. The intersection of Saxon Drive /Christensen Drive is operating at capacity on Saturdays. Additional trips will add to delays at the intersection. One solution to this issue is to stripe the southbound movement to add a right -turn lane, so that the southbound movement has a through lane and a right -turn lane. It may be necessary to remove a portion of the traffic island adjacent to the southbound lane to attain the proper lane width /turning radii. The additional lane improves operations at the intersection dramatically. The Saturday peak no longer operates at LOS F, but improves to LOS C. Also, operations in the eastbound and northbound direction improve, and queue lengths are reduced by over 4 vehicles for both movements.

Delay is measured in seconds. 2. Queue is measured by number of vehicles. As was stated previously, the additional pumps will help address the demand for pump space, and thus reduce the queues at each pumping station. However, if the additional pumps generate significantly more trips, then the amount of storage space for the queue at the gas pumps should be extended. Queues for the gas station should not back into Saxon Drive. If the additional pumps do not reduce queues at the gas station, it is recommended that additional queue capacity space be provided. The northbound queue at the intersection of Saxon Drive /Christensen Drive occasionally backs past the exit to the gas station, causing delays to left- turning vehicles out of the gas station. It is recommended that the exit to the gas station be moved south to ease left turns out of the site when the number of pumps is increased. The mitigation for the proposed project is based on the Mitigation Proportionate Fair Share Costs for various intersections as presented in the Transportation Element of the City's Comprehensive Plan. The amount to be submitted for mitigation is based on the total project -trips entering the intersections from the project at rates proportionate to the cost of projected improvements per trip.

Based on conservative trip generation analysis developed from a gas station patron survey, the additional four pumps may generate 14 net new trips during the weekday noon peak hour, 12 net new trips during the p.m. peak hour, and 18 net new trips during the Saturday peak hour. The survey determined that trips generated by the gas station are 41 to 50 percent internal trips, or trips made between the Costco Wholesale Store and the gas station, and pass -by trips ranged between 28 to 43 percent depending on the peak period. A LOS analysis was conducted at the intersections of Saxon Drive /Andover Park East, South 180th Street/Andover Park East, South 180th Street/Sperry Drive, and Saxon Drive /Christensen Drive during the weekday noon and p.m. peak hours as well as the Saturday peak hour. The existing LOS conditions currently experienced at the three signalized intersections range between LOS B and LOS C. The three -way stop sign at Saxon Drive /Christensen Drive operates at LOS F during the Saturday peak hour. With the project, when the Costco gas station is expanded to 16 pumps, the LOS at the three signalized intersections remained unchanged and ranged between LOS B and LOS C, W:\98118\Reports \CtukTIA (3/16/99) / kb 14 z Fw re .UO CO W= cn u.

The mitigation defined at this time consists of a mitigation payment of $11,604 for project traffic entering specified intersections with required improvements as identified in the City's Transportation Element. In addition, to improve operations on -site at the intersection of Saxon Drive /Christensen Drive, it is recommended that an additional southbound right -turn lane be provided. With the southbound right -turn lane, operations improve to LOS C or better. It is recommended that the queue capacity at the gas station be increased to prevent vehicles from backing into Saxon Drive. It is also recommended that the exit to the gas station be moved south to ease left turns out of the gas station when the number of pumps is increased.

The ratio of existing traffic volume to available capacity provides a measure of intensity of traffic loading relative to the ability of the street intersection to accommodate the traffic. The number of lanes, presence of turn lanes, type of traffic control, signal phasing, etc., are important factors determining capacity. As the volume /capacity (v /c) ratio approaches a value of 1.0, extreme congestion sets in, with long backups at signalized intersections and the passage of several complete changes of the signal cycles before a motorist can proceed. Motorists at stop -sign controlled intersection approaches face extremely long delays. As traffic queues lengthen, this congestion can also impede access to and from upstream abutting property. The term "level of service" is used to describe traffic flow at intersections. For signalized intersections, the level of service is essentially based on v/c ratios (see table B -1). Table B -1 Level of Service and Volume /Capacity Ratio Relationships for Signalized Intersections Level of Stopped Delay Intersection Service General Description (seconds /vehicle)1 V/C Ratio2 A Free flow <_ 5.0 5 0.60 B Stable flow (slight delays) 5.1 to 15.0 0.61 to 0.70 C Stable flow (acceptable delays) 15.1 to 25.0 0.71 to 0.80 D Approaching unstable flow 25.1 to 40.0 0.81 to 0.90 (tolerable delay - occasionally wait through more than one signal cycle before proceeding) E Unstable flow (intolerable delay, 40.1 to 60.0 0.91 to 1.00 intersection operating at capacity) F Forced flow (jammed) > 60.0 > 1.00 1.

O l z Level of service "A" is a condition of unimpeded flow, while level of service "C" is often used in the design of new urban streets as the lowest acceptable level for peak periods. Congestion begins to occur at level of service "D" (v /c from 0.81 to 0.90). Because of funding and /or environmental constraints for improvements, this level of service is being used by more and more cities as an adequate level, particularly for improvements to congested existing facilities. Increasingly unstable traffic flow with excessive delay and congestion occurs as level of service "E" (capacity) is approached (v /c = 0.91 to 1.00). For v/c > 1.00, level of service "F" (forced flow) is obtained, and the intersection is overloaded or is jammed due to traffic backups from overloaded downstream intersections. Table B -2 shows daily traffic volumes corresponding to peak -hour level of service C, D, and E (capacity) applicable to suburban arterial roadways of various numbers of lanes and configurations. Table B -2 Guidelines for Relating Average Weekday Daily Traffic Volumes to Peak -Hour Level of Service for Suburban Arterials of Various Roadway Lane Configurations Daily Two -Way Traffic Volume for Various Levels of Servicel Total Number Lane E of Lanes Configuration C D (capacity) Two -Way Streets 2 Two Lanes 8,000 11,000 13,000 3 Two Lanes with Left -Turn Lane 10,000 14,000 16,000 4 Four Lanes 16,000 23,000 26,000 5 Four Lanes with Left -Turn Lane 21,000 29,000 32,000 6 Six Lanes 25,000 36,000 39,000 7 Six Lanes with Left -Turn Lane 31,000 45,000 49,000 One -Way Streets 2 Two Lanes 12,000 17,000 19,000 3 Three Lanes 19,000 27,000 29,000 4 Four Lanes 23,000 33,000 36,000 5 Five Lanes 29,000 42,000 45,000 1. The volumes represent maximums for the daily volume that will result in levels of service indicated during peak hours, with an average spacing of 2.5 to 4.5 signalized intersections per mile. For approximations at other signal spacings, multiply the above service volumes as follows: Signals per Mile LOS C LOS D LOS E 0.50 -2.49 Over 4.5 multiply by: 1.55 multiply by: Not Possible 1.16 1.06 0.87 0.99 Prepared by Entranco based on data in the Florida Department of Transportation "Level of Service Standards and Guidelines Manual ", April 1992.

I O ~. z It should be noted that equal v/c ratios at several locations do not necessarily indicate equal overall performance of intersections, since one location may experience a high v/c ratio for a considerable period of the day while at another the peak period is of short duration. In addition, a low level of service is more tolerable at a low- volume intersection than a high - volume location. The general level of service concept also holds for stop -sign controlled intersections, although the capacity of the stop -sign controlled approaches is less than that of the signalized intersection approach. Table B -3 shows the level of service criteria for unsignalized intersections. Capacity analysis for two -way stop -sign controlled intersections is based on the assumption that major street traffic is not affected by the minor street movements, and left -turns from the major streets to the minor streets are influenced only by opposing major street through flow. The level of service calculated for two -way stop intersections is therefore based on delay experienced by only the minor street movements and the major street left -turn movement. Table B -3 Level of Service Criteria for Unsignalized Intersections Average Total Delay (d)1 Level of Service d<_5 5 <d <_10 10 <d<_20 20 <d530 30 <d <_45 d > 45 A B C D E F 1. Average total delay is measured in seconds per vehicle. 2. For level of service F, when demand volume exceeds the capacity of the lane, extreme delays will be encountered with queuing which may cause severe congestion affecting other traffic movements in the intersection. This condition usually warrants improvements to the intersection. Source: "Highway Capacity Manual ", Special Report 209, Transportation Research Board, 1994.

SHORELINES DESIGN POLICIES All projects in the Shoreline Zone must be consistent with Tukwila's Comprehensive Plan and Shoreline Master Program policies (or King County's Shoreline Master Program if project located north of the 42nd Avenue bridge). In addition, all structures requiring a building permit (except single family development of 4 or fewer lots) located in the Shoreline Zone must undergo design review with the Tukwila Board of Architectural Review (BAR). The BAR's decision is based on design guidelines contained in the Zoning Code (TMC 18.60.050) and the Tukwila Comprehensive Plan (see DESIGN REVIEW APPLICATION). The SHORELINE MASTER PROGRAM POLICIES and Comprehensive Plan's SHORELINE DESIGN POLICIES are summarized below. Note that more than one category may apply. In some cases, the goal. for the use or area is noted to provide context for the design policies. NOTE: a) If your project requires a building permit you must meet additional criteria in DESIGN REVIEW APPLICATION. b) If your project requires a variance, you must meet additional criteria in VARIANCE PERMIT APPLICATION. c) If your project requires a conditional use permit, you must meet additional criteria in CONDITIONAL USE PERMIT APPLICATION. TUKWILA SHORELINE MASTER PROGRAM POLICIES (King County shoreline policies follow) A. ECONOMIC DEVELOPMENT ELEMENT 1. CommerciaVindustrial development along the shorelines should not favor outside interests at the expense of the local population. 2. Locate commerciaVdevelopment in areas with low potential for recreation or other public uses. 3. Preference should be given to commercial /industrial development that will provide an opportunity for a substantial number of people to enjoy the shoreline. SSDPMT.DOC 7/3/96 6 • 4. Determine and consider the visual impact that the commercial /industrial development will have on the surrounding area. 5. Encourage provisions for public access, especially visual and pedestrian, as an integral part of commercial /industrial waterfront development. 6. Design new commercial /industrial facilities and improve existing ones in such a way as to minimize wasteful use of the shoreline. 7. Encourage multiple use types of commercial /industrial development to provide public access and promote round - the -clock utilization of the shorelines. 8. Short -term economic gain or convenience in developments should be evaluated in relation to long -term and potential impairments to the desirable biological features of the river and its shoreline. B. PUBLIC ACCESS ELEMENT 1. Public access to and along the water's edge should be provided in new developments. a. Water- dependent economic activities should be designed to allow substantial public access to the shoreline. b. For non -water dependent economic activities, where permitted, the entire water's edge should be available for public access, consistent with private property rights. c. For multi - family residential developments, the water's edge should be kept free of buildings and fences with public access made possible. d. For a new single - family dwelling unit, the water's edge should be kept free of buildings and fences. e. For other non - specified development, the water's edge should be available for public access. f. All public shorelands, except as noted in other policies, should be available for public access to the water's edge. 2. Any modifications or extensions to existing development should be designed to allow public access. 3. A trail system should be developed along the river. a. Trails should be developed for linear access through public shoreline areas. b. Access points to and along the river should be linked by a system of trails. c. The connection of other trails in the region to the shoreline trail system should be encouraged and developed. d. To assist in developing a trail system, incentives should be offered to property owners for utilizing set -back areas. C. CIRCULATION ELEMENT 1. Roadways adjacent to the shoreline should be designed primarily for slow- moving traffic that would provide for recreational activities.' 2. Parking facilities should be located upland with provisions for adding pedestrian access to the shoreline. 3. Public transportation should be designated to facilitate access to and along the shoreline. 4. Railroads should be encouraged to offer their rights -of -way for multiple use consistent with a shoreline location and with public safety. D. RECREATIONAL ELEMENT 1. Publicly owned recreational uses should be enhanced and, when feasible, enlarged. SSDPMT.DOC 7/3/96 1.. • .iq. ..littiiM+M[,.t4«�ri�ar .r.. .. .- a. The public should have first option to buy shoreland as it becomes available for sale, based on an acquisition plan with clear public intent. b. The opportunity for sport fishing in the river should be enhanced. 2. Recreational uses should be incorporated with other shoreline activities. 3. Those unique or fragile areas of the shoreline which cannot be maintained in a natural condition under human uses should be designed and maintained as open space for passive forms of recreation. 4. Views of the shoreline and water from shoreline and upland areas should be preserved and enhanced. a. New shoreline development should not significantly obstruct views of the shoreline or the water. - b. Enhancement of views shall not be construed to. mean excessive removal of vegetation. E. SHORELINE USE ELEMENT 1. Shoreline activities identified as being appropriate shoreline uses should be planned for and encouraged. a. Short-term economic gain or convenience in developments should be evaluated in relationship' to long -term and potential impairments to the desirable biological and aesthetic features of the river and its shoreline. b. Preference will be given to those activities which protect and enhance the desirable features of the river, depend on a shoreline location, and /or provide public access to the shoreline. c. Shorelines particularly suited for a specific and appropriate use or activity should be planned for and designated. d. Multiple use of shorelines should be planned for locations where integration of compatible uses is feasible. 2. Relocation of those activities identified as being inappropriate should be planned for and encouraged. 3. Aesthetic considerations should be encouraged when contemplating a new development, redevelopment of existing facilities or for general enhancement of shoreline areas. 4. Planning, zoning, capital improvements and other policy and regulatory standards should not tend to increase the density or intensity of activities on the shoreline. F. CONSERVATION ELEMENT 1. Determine and consider the visual impact a commerciaVindustrial development will have on the surrounding area. 2. Develop regulations requiring the maintenance of a buffer of permanent vegetation between developed areas and associated water bodies to improve the aesthetic qualities of the river, retard surface run -off, maintain constant water temperature and reduce siltation. 3. Promote linear shoreline access, especially pedestrian and other non - motorized types, in the areas close to population centers; such areas would also serve as buffer between water and developed areas. 4. Develop regulations for site coverage, building height, set -backs and density to insure visual access to water, promote interesting development and prevent encroachment over water. 5. Provide facilities for intensive recreational activities where the sewage disposal and vector control can be accomplished to meet public health standards without adversely altering the natural features attractive for recreational uses. SSDPMT.DOC 7/3/96 8 6. Evaluate the effect of proposed recreational developments on environmental quality and natural resources of an area. 7.
