                   Introduktion

                                         bilver Lake serves the Everett community in many ways. It is the
                                         area's most popular warm water lake for swimming, boating and
                                         fishing. it receives local storm water run off. Numerous species
                                         of wildlife find a home in its waters and forested uplands. It is
                                         the focus of local neighborhoods. Silver Lake Park provides a
                                         setting for variety of recreational activities. The lake lies near
                                         the corridors of several regional and local traffic corridors, and
                                         finally, it is the locale's most identifiable landmark.

                                         Understanding the importance of Silver Lake as a public resource,
                                         the City of Everett is undertaking a series of steps to insure that
                                         the lake is put to optimum public benefit. As a part of the City's
                                         effort, this plan's primary purpose is to serve as a basis for
                                         requirements to be added to the City of Everett Shoreline
                                         Management Master Program as authorized by the Washington State
                                         Shoreline Management Act of 1971. Everett's Master Program sets
                                         requirements for development within 200 feet of the shoreline. The
                                         requirements are intended to enhance opportunities for water-
                                         dependent activities and the ability of the general public to enjoy
                                         the shoreline. Specifically, at Silver Lake, the master program
                                         amendments will provide better public access to the shoreline and
                                         increase water-oriented recreational opportunities.

                                         One purpose of this plan is to coordinate individual public and
                                         private development actions into an organized scheme that maximizes
                                         benefit to the public, to private property owners and to the
                                         quality of the lake itself. But Silver Lake's potential goes
                                         beyond what can be accomplished strictly by regulatory measures.
                                         Because of Silver Lake's multi-faceted role, any plan to guide the
                                         future must include public improvements, park master planning and
                                         infrastructure construction and should consider a broad range of
                                         planning objectives dealing with the following elements:

                                               1.   Recreation and public access
                                               2.   Traffic, circulation and parking
                                               3.   Water quality
                                               4.   Management of shoreline development
                                               5.   Environmental enhancement
                                               6.   Community development
                                               7.   Visual identity

                                       Thus, this plan is comprehensive in nature, with special emphasis
                                       on coordinating various elements and other public land use,
                                       transportation and environmental management efforts into a unified
                                       scheme.

                                       The document itself is structured to first discuss the existing
                                       conditions, objectives and recommendations related to each element
                                       and then to describe how the various elements are coordinated to
                                       support one another into a comprehensive vision for Silver Lake's
                                       improvement. Finally, an implementation program is presented which
                                       outlines the actions to be initiated by the many public and private
                                       participants who will be involved with the lake's future.

                                                                      7

                        History

                                       Looking at Silver Lake's park and residential setting, it is hard
                                       to imagine that the area has had a dynamic history, or that the
                                       lake itself has been the site of a wide variety of commercial,
                                       recreational and even military activities. The sequence of
                                       development that has occurred over the past century has resulted
                                       from the lake's natural attractions and its location along
                                       principal transportation routes.

                                       The local Native Americans recognized the value of Silver Lake's
                                       amenities, and long before the first white pioneers arrived in
                                       Puget Sound, Silver Lake was the site of a Snohomish Indian
                                       community. Even though the lake was far from the early settlements
                                       of Everett and Seattle, its location along the military road
                                       brought development to the area relatively early. The first Silver
                                       Lake real estate plat was filed in 1883. In 1910 the Seattle-
                                       Everett Interurban railway opened, and due to convenient access,
                                       Silver Lake blossomed into a popular recreation spot. By the
                                       1920's, resorts, amusement parks and fairgrounds ringed its
                                       shoreline. The depression era brought a decline to Silver Lake's
                                       role as a bustling recreational center. The Snohomish County
                                     Jairgrounds moved to Monroe and in 1939 the Interurban Railroad
                                       terminated service. With these changes, permanent lake front
                                       homes began to replace resort activities. In the 1950's the south
                                       end of the lake was used as a log holding pond for Casper's Shingle
                                       Mill. Construction of the Silver Lake Shopping Center and
                                       Interstate 5 in the 1960's brought a new wave of development to the
                                       locale. In 1969 the northwest quadrant of the lake's shoreline was
                                       annexed by the City of Everett.

                                       During the past decade, the south Snohomish County region has
                                       undergone extensive development associated with the Everett Mail,
                                       the 1-5 high technology corridor and residential growth between
                                       Bothell and Everett. As a result, traffic has increased
                                       dramatically on SR 527 along the lake's eastern shoreline and there
                                       is substantial pressure to develop the area immediately around the
                                       lake. In 1984 the City of Everett annexed the remainder of Silver
                                       Lake and its immediate vicinity. At that time, tracts of land were
                                       rezoned to allow office and multi-family residential development
                                       and a local improvement district formed to install sewer lines. A
                                       major impetus for the annexation of the entire shoreline was that
                                       placing the area in a single jurisdiction allows better
                                       coordination of land use planning, shoreline management regulations
                                       and public improvement programs.

                                       -Today the challenge is to accommodate the developmental pressure
                                       resulting from Silver Lake's strategic location in the region and
                                       at, the same time, to enhance its environmental and recreational
                                       assets for greater public benefit.

                                       With regard to planning for Silver Lake's future, two land use
                                       characteristics stand out. The first is the wide variety of land
                                       uses that currently surround the lake. Unlike most other small
                                       takes in the region, Silver Lake's shoreline is a finely grained
                                       mixture of commercial business, single-family and multi-family
                                       residences, active and passive park lands and heavily vegetated,
                                       undeveloped land. This presents some planning issues because the
                                       long term objectives of neighboring land uses are not always
                                       compatible. For example, single family residences along the
                                       shoreline discourages the establishment of continuous public path
                                       at the water's edge. On the other hand, the mix of activities adds
                                       a variety and,balance that, if properly organized, can enrich the
                                       take's visual character and its role as a recreational and
                                       community  focal point.

                                       Silver Lake Park isaregional recreation resource andasignificant land use activity.

                                       The second important land use characteristic is the number of large
                                       development projects planned near the south and cast shorelines.
                                       Because of their size, these projects may result in a significant
                                       impacts on transportation systems, storm water run-off,
                                       recreational needs and visual character. However, large project
                                       development of open land has some public advantages. For example,
                                       continuous public access at the shoreline and will be required of
                                       commercial, office and multi-family projects. This requirement
                                       would be more difficult to achieve with numerous single family or
                                       small ownership land development.

                                        The key to dealing with land use issues will be to maximize the
                                        compatibility of the different activities and to utilize the
                                        positive opportunities associated with new development while
                                        mitigating its negative impacts. The fact that all fo the
                                        shoreline and associated uplands are within teh City of Everett
                                        jurisdiction is an important advantage. If the jurisdiction was
                                        split between the city and the county coordination of land use and
                                        shoreline management regulations would complicate effective
                                        planning and implementing improvement programs would be much           more

                                        Transportation

                                        Situated between Interstate 5 and State Route 527, Silver Lake is
                                        very accessible by automobile. Less desirable is the fact that SR
                                        527, also known as the Everett-Bothell Highway, is a busy, regional
                                        north-south corridor carrying approximately 16,000 vehicles per day
                                        along the eastern shoreline. The high speed, high volume traffic
                                        detracts from the lake's environmental quality and makes pedestrian
                                        access dif f icult. Traf f ic along Silver Lake Road to the west and
                                        south of the lake amounts to about 5,000 vehicles per day and is
                                        much less damaging to the lake's recreational activities because of
                                        its lower speeds and greater distance from the lake shore.

                                        Several traffic circulation improvements are currently planned or
                                        in process. State Route 527 will be widened from two to three
                                        lanes as projects are developed, and a signal will be installed at

                                        occurring to the east of the current alignment so away from the
                                        lake shore.

                                        In addition, 112th St reet S.E. (Stock Show Rd.) is being widened
                                        with new sidewalks. New freeway exit and entrance ramps to the
                                        south of 112th St. S.E. are being considered. If implemented, the
                                        proposed ramps will impact the intersection of 112th and Silver
                                        Road increasing the need to relocate this intersection further to

                                        Environmental Conditions

                                        For a small, low elevation lake in an urban setting, Silver Lake
                                        enjoys remarkably good water quality. This is partly because the
                                        lake is comparatively deep and some of thei-,streams feeding the lake
                                        still flow over undeveloped land where pollutants are filtered out
                                        by the wetland vegetation and natural sedimentation. A report by
                                        the University of Washington Engineering Department describes
                                        current water quality conditions in the lake and recommends steps
                                        to take for its maintenance.

                                        The most obvious of Silver Lake's environmental assets is the wide
                                        variety of vegetation zones and visual qualities. While portions
                                        of the take have a residential character with lawns and gardens
                                        extending to the water, Silver Lake Park and the trailer court at
                                        the west shoreline posses large stands of tall evergreen trees in a
                                        naturalistic park setting. The park lands west of the Silver Lake
                                        Drive include a densely vegetated area which provides habitat for
                                        small mammals and a nature trail.

                                        The southern portion of the lake is an expansive wetland with emer-
                                        gent zone (water plants growing up through open water) scrub-brush
                                        zone (shrubs and small trees), and an upland forested zone with a
                                        substantial stand of white pine, an unusual plant type for this
                                        area. This wetland, with its mix of vegetation types, provides an
                                        excellent wildlife habitat and there are beaver huts to attest to
                                        this f act.

                                        The western and north-eastern shorelines are in a badly eroded
                                        condition due to heavy use and their proximity to SR 527 with its
                                        runoff and off-thc-shouldcr parking. Cottonwood trees and some
                                        small shrubs manage to survive, but this portion of the shoreline
                                        requires significant regrading and revegetation. To the east of SR
                                        527 is a small, shallow pond connected to the take which makes a
                                        very attractive setting for the surrounding properties and a
                                        protected habitat for birds.

                   Planning Obje                 ctiv-es'

                                        Silver Lake is multifaceted public resource used for a variety of
                                        purposes. It is Everett and southern Snohomish County's most
                                        popular recreational lake, attracting thousands of swimmers,
                                        boaters, and fishermen each year. It is the focus for a growing
                                        residential community. Many species of wildlife also find a home
                                        in its variety of shoreline habitats. Several regional circulation
                                        corridors traverse nearby and the area's storm drainage uses flow
                                        in its waters. Because of its multitude of functions, successful
                                        planning of Silver Lake's future must necessarily address a broad
                                        range of goals. The planning objectives that guide this plan were
                                        developed in workshops with staff members from Everett Department
                                        of Planning, Parks and Recreation, Public Works and Engineering.
                                        Representatives from Snohomish County Parks and Recreation Division
                                        were also consulted to coordinate bicycle route planning. Early in
                                        the planning process, an open house was held in the Silver Lake
                                        community and a questionnaire circulated to elicit community input
                                        regarding the project's objectives. The objectives listed below
                                        compile the ideas f rom these ef f orts, and serve as a -basis f or the
                                        concepts and recommendations developed in the planning process.

                                                    regional bicycle trails. (However, do not allow bicycle
                                                    traffic to interfere with pedestrian traffic on foot

                                        These components are described'on the following pages and then
                                        combined into a comprehensive planning vision which organizes the
                                        separate elements into a unified whole.

                                         Planning Silver Lake's future involves the consideration of pedestrian access, water
                                         quality, recreation, visual character and natural systems.

                                                                10.

                                        Pedestrian Access and Circulation

                                        FOOTPATH

                                        The primary impetus of this element is the construction of a
                                        footpath that will allow pedestrians to comfortably walk around the
                                        lake and connect various recreational activities and points of
                                        interest. Because single family residences are not required to
                                        provide public access at the water's edge, the path will not follow
                                        the- shoreline through single family neighborhoods. In these areas
                                        the trail will be directed to sidewalks along public streets. The
                                        Everett Shoreline Master Program, as authorized by the Washington
                                        State Shoreline Management Act, does require public access be pro-
                                        vided along the shoreline for all new commercial and multi-family
                                        residential development. As vacant properties are developed around
                                        the lake, this requirement will be used, along with publicly funded
                                        improvements to develop a footpath with pedestrian amenities and
                                        landscaping. In addition, the City of Everett has acquired several
                                        properties along the shoreline that provide vital links in the
                                        pathway route shown in the plan.

                                        The pathway's width, paving and landscaping will vary from section
                                        to section to provide a diversity of settings including natural
                                        woodlands, park beachfront, residential and commercial.

                                        Cross sections of various pathway segments are illustrated below
                                        and on the following pages. The circulation plan indicates where
                                        each of the sections are located. It is important to note that
                                        along with the construction of the path will be landscaping to
                                        improve the quality of shoreline areas and residential streets
                                        along the footpath route. The landscaping design concepts for
                                        these areas are described in the section on visual design and
                                        landscaping.

                                        There is a natural desire for people to walk directly to the
                                        water's edge for fishing, sitting, launching rafts, swimming and
                                        viewing. To provide for this tendency and prevent destruction of
                                        delicate shoreline vegetation, fishing pads, seating areas, small
                                        beaches and walkway spurs should be provided at frequent intervals
                                        along the trail.

                                        The path segments on the east and    north side of the lake are
                                        illustrated in Cross-section A showing the relation of the path to
                                        the street and shoreline. The recommended path configuration here
                                        is 8' wide, allowing two couples to pass each other comfortably.
                                        Asphalt, gravel or concrete would be appropriate paving materials.
                                        Segments of gravel pavement will discourage roller-skaters and
                                        cyclists, and concrete might be appropriate for ramps or special
                                        features. Asphalt will provide an easily maintainable, cost-
                                        effective and versatile surface. The primary pathway design issue
                                        in this segment is shielding the pedestrian from the noise and
                                        distraction of high speed traffic along 527. To mitigate this
                                        irritant, the path's route is located away from the street. In

                                         edge and for bus stops. This sidewalk will also provide a
                                         continuous route around the lake until other segments are
                                         constructed as part of the shoreline permit process. Another
                                         critical aspect of the SR-527 improvements is the inclusion of a
                                         grass swale at the cast side of the street to filter storm water
                                         run-off. The importance of grass swales is discussed in the Water
                                         Quality section.

                                                  An over-water boardwalk is recommended at the north-east cove in
                                                  order to further separate pedestrians from traffic, provide a

                                                  viewing of the small wetland area. A 6' wide walkway has proven to
                                                  be sufficient in similar trails and narrowing the width will reduce
                                                  the cost and make a more intimately scaled structure. Several
                                                  decks should be provided along the boardwalk for fishing, nature

                                               and signing the street as a bike route will provide for bicycle

                                               be added on the north side of the street. The landscape and

                                       At. Silver Lake Park, the trail route branches to an upper walk
                                       through the wooded parklands and a beach front esplanade at the
                                       back side of the swimming beach. This broad walkway (approximately
                                       16' wide) will allow ample space for strolling, people watching and
                                       informal gathering. Beach facilities such as restrooms, showers,
                                       lifeguard quarters, picnic shelters and concession snack stands
                                       will be located along the esplanade making it an activity spine.
                                       The walk will be raised slightly above the beach area with steps
                                       that can be used for informal seating.

                                       The character of the esplanade will be reminiscent of the early
                                       20th century beach-front boardwalks. Concrete is the most durable
                                       pavement for the use and can be scored in transverse panels to
                                       suggest a wood plank boardwalk.

                                       a new sidewalk at the north side of Silver Lake Drive. A parking
                                       lane will be developed where desired by adjacent property owners
                                       and appropriate landscaping installed. Sections E, F, and G show
                                       the street configurations at the indicated segments along the
                                       route. The only area where adding a sidewalk will be difficult is
                                       at the elbow at Section G. where the roadway is so narrow that a
                                       sidewalk extension with retaining wall and guardrail should be

                                           wide landscape zone. Buildings will be set back from the shoreline
                                           and wetlands a minimum of fifty feet. These requirements will help
                                           maintain the natural character of the wetlands and low wooded
                                           areas. An 8' wide pathway with gravel or asphalt paving should be
                                           located sufficiently back from the shoreline so that it does not
                                       @ew 8' parki

                                           disturb sensitive habitats or cause shoreline degradation. Where
                                           possible, native vegetation including trees should be maintained to
                                           provide a buffer between the residential units and the path.

                                        BICYCLE ACCESS

                                        The footpath will be inappropriate for bicycle traffic and so a
                                        separate bicycle route is recommended that will connect the major
                                        recreation features to planned regional bicycle routes as shown in
                                        the circulation component plan. Because much of the bicycle path
                                        will be on street R.O.W. and because the connecting regional
                                        bicycle trails will be along heavily trafficked streets, the
                                        bicycle trail is not intended as a route for children and casual
                                        riders but will serve commuters and experienced cyclists.

                                        PARKING AND ACCESS POINTS

                                        Because the take is bordered by SR 527 and single-family residences
                                        along much of its perimeter, parking and easy pedestrian access to
                                        the footpath is restricted in many sections. To alleviate this
                                        problem and accommodate increased use, the plan recommends the
                                        development of an additional 400 parking spaces within the park,
                                        and an additional 100-200 space lot at the south end of the lake.
                                        The south-lake parking, lot will require, public acquisition of
                                        property immediately south of Silver Lake Road, as shown on the
                                        access plan. This will augment the existing 395 stalls parking lot
                                        at the park. Because of the proposed widening, there will be no
                                        ?n-street parking along highway 527. Pedestrian access will be
                                        improved by a traffic signal at 116th Avenue S.E. Other crosswalks
                                        on the h .ighway are located to provide the maximum sight distance in
                                        both directions.

                                        VEHICULAR TRAFFIC

                                        As noted in the description of existing conditions, there are
                                        several major traf f ic improvements, especially the widening of SR
                                        527, that will significantly impact the Silver Lake area.
                                        Fortunately, the engineering plans show the highway widening to
                                        occur to the east of existing pavement so that the new roadway
                                        surface will not encroach into the lake shore. However, any
                                        additional widening above the three lanes should be evaluated
                                        carefully to determine whether or not the widening to 5 lanes would
                                        genuinely add to-traffic safety and fulfill a regional need.

                                        A more positive improvement from the standpoint of lake's rec-
                                        reational uses is the relocation of Silver Lake Road SE around the
                                        present parking lot so that park visitors will be able to walk from
                                        their cars to the beach without crossing a street. If the proposed
                                        freeway ramps are developed the parking lot and road realignment
                                        will be moved slightly to the east but the parking lot should still
                                        be able to accommodate 450 to 500 spaces with better organization
                                        and some expansion to the north-cast.

           Silver Lake Shoreline Management & Access Plan

                                       Water Qual ity

                                       Maintaining high water quality for swimmers and boaters is a
                                       primary public goal. To serve that purpose the recommendations
                                       presented here are intended to support the findings of the Silver
                                       Lake Water Ouality Nutrient Loadin"nd Management Rev2jrt prepared
                                       by the University of Washington Civil Engineering Department for
                                       the ]Everett Department of Public Works. The UW/ Public Works Study
                                       identifies vegetation nutrients such as phosphorous carried in
                                       storm water run-off as the primary threat to Silver Lake's water
                                       quality. Too many nutrients in the water can promote undesirable
                                       levels of algae and other microscopic life. Additionally, heavy
                                       metal and petroleum pollutants from street pavements arc a
                                       significant problem.

                                       Although the lake's water quality is presently quite good,
                                       additional development will increase the amount of nutrients and
                                       pollutants in the run-off from paved surfaces and developed sites.
                                       Recent research has shown that the most effective way to reduce
                                       these pollutants in a fresh water take is to route the water run-
                                       off through wetlands, detention ponds, sedimentation areas and
                                       grass lined swales before it reaches the lake itself. Grasses and
                                       aquatic plants absorb the nutrients and heavy metal pollutants,  and
                                       much of the  sediment settles to the bottom of the ponds.

                                       Wet lands such as this one are very effective in biologically purifying storm water run-
                                       off, especially when they are located a distance upstream from the take.

                                       Such wetlands also provide excellent  habitats for wildlife and
                                       young fish. Enhancement of wildlife habitat and the natural
                                       character at Silver Lake was also identified by the community as a
                                       high priority objective. Unfortunately, larger wetland areas
                                       directly along the lake's perimeter can reduce water quality for
                                       swimmers because decayed plant material releases nutrients that

                                                              21

                                         feed algae. Also, large populations of water fowl can degrade
                                         water quality, especially if fed by people. Therefore, the
                                         addition of large wetlands on the lake's edge are not recommended,
                                         although the retention of the existing natural wetland at the south
                                         end of the lake and the establishment of a small wetland area in
                                         the lake's north-eastern cove will not significantly reduce water
                                         quality. This is because the water at the southern wetland is
                                         drained directly into the take's out-fall, and the proposed wetland
                                         area at the north will be smaller and its expansion limited by deep
                                         water.

                     Once  pollutants, nutrients and                   Silver Lake should be treated as
                     sediments reach the lake it is very               part of a water management system
                     difficult to remove them and clean                with run-off treated before it
                     the water.                                        enters the lake.

                                         To successfully improve Silver Lake's water quality, storm water
                                         run-off must be intercepted and biologically filtered before it
                                         enters the lake. Several of the plan's elements will serve as
                                         positive water quality improvements. The creation of the
                                         wetland/nature walk in Silver Lake Park will help to purify the
                                         run-off from the freeway which currently flows directly into the
                                         swimming area. The pipe carrying this water should be extended
                                         away from the beach further and deeper into the -lake. The grass
                                         lined swales which are recommended as part of this plan's
                                         landscaping and street improvement components are also a proven
                                         pollutant filtering technique. Vegetation restoration along the
                                         shoreline will help to prevent erosion that introduces sediment and
                                         runoff pollutants into the lake. The Everett Shoreline Master
                                         Program will require on-site treatment of runoff through
                                         sedimentation ponds or wetqland/grass swale systems. In addition,
                                         the UW/Everett Public Works study recommends a regional water
                                         management plan and public education program. Together, these
                                         actions will help to keep Silver Lake one of the region's premier
                                         "swimming holes".

                                          Silver Lake Park

                                          Silver Lake Park, also known as Thorton Sullivan Park, is the gem-
                                          stone in Silver Lake's ring of recreational resources. The park's
                                          swimming beaches are crowded with over 3500 visitors a day during
                                          the warm summer months. At other times of the year, the park makes
                                          a wooded setting for a quiet stroll. The challenge for
                                          masterplanning Silver Lake Park is to accommodate an increasing
                                          number of swimmers and boaters, to allow for other recreational
                                          activities and to coordinate with changing land use and circulation
                                          patterns. These challenges are matched by the opportunity to
                                          expand park grounds through the acquisition of the trailer court
                                          property to the south.

                                                                                      171,

                                          While  in-depth- masterplanning of @Silver, Lake Park   is beyond the
                                          scope  of--tbis..plan, there are several comprehensive  issues which
                                          point  to directions for park masterplanning. Namely:

                                                 1.   Use of the trailer court site for additional beach areas
                                                      and a "car-top" boat launch.

                                                 2.   The need for additional parking and road revisions to
                                                      provide better vehicular access.

                                                 3.   Incorporation of park lands into the pedestrian loop
                                                      trail.

                                                 4.   Water quality and environmental enhancement actions.

                                                 5.   Provision for other recreational activities.

                                                                   24

                                      The schematic plan presented here illustrates one way these issues
                                      can be arranged. It is drawn in greater detail than is customary
                                      for a schematic plan in order to present an understandable picture
                                      of how the park could function. Below are described some of the
                                      conceptual ideas for the park's proposed improvements.

                                            Swimming Beach_ Expansion - The acquisition of the trailer
                                            court property will allow an approximately 66% increase in
                                            swimming beach area and the addition of a "car top" boat
                                            launch.

                                            Esplanade/FootQath - Silver Lake Park will be a principal
                                            focal point on the loop trail around the lake. The trail will
                                            pass-through wooded glens and open spaces and connect to the
                                            parking lots, but the principal attraction will be a wide
                                            "boardwalk" along the swimming beach. This boardwalk
                                            esplanade will be slightly elevated above the beach to provide
                                            better viewing and informal seating. The boardwalk is
                                            -envisioned as a high-activity spine, and bathhouses, lifeguard
                                            facilities, and (if desired) concession stands will be located
                                            along it. It will also serve an organizational purpose,
                                            providing a back edge to the bathing area and convenient route
                                            for lifeguards, emergency vehicles and park management staff.
                                            Specially scored and textured concrete may prove to be the
                                            most appropriate paving for the "boardwalk".

                                            Parking - To accommodate additional visitors at peak times on
                                            summer weekends the parking will be expanded from the current
                                            395 spaces to approximately 800 spaces. Two new lots are
                                            proposed in the south and central portions of the park. The
                                            south lot, with about 250 spaces will serve boaters and will
                                            be oriented in an east-west direction to minimize impact on
                                            the lake. The central lot will accommodate about 100 cars and
                                            its location should be determined by the topography and rela-
                                            tion to nearby picnic areas. The northern lot will occupy
                                            approximately the same location as the present lot but be
                                            reconfigured to hold about 450 cars.

                                            Road RealignmCnts - The proposed road realignment of Silver
                                            Lake Road to the west of the main parking lot will allow park
                                            visitors access to the beach without having to cross a street
                                            and will provide better traffic circulation as well.
                                            Everett's Public Works Department and State Department of
                                            Transportation are is also studying the addition of a north
                                            bound exit ramp off of 1-5. This possibility will require the
                                            reconfiguration of the north parking lot and the relocation of
                                            the intersection at 112th Street towards the east. While

                                             areas be designed to provide a range of landscape character
                                             and activity centers. The southern most open space would make
                                             an appropriate area for teenagers and young adults because of
                                             its topography and proximity to boating and parking facili-
                                             ties. Frisbee tossing, listening to music, congregating and
                                             sun bathing could occur here. The central open space, because
                                             of flatter topography and enclosed configuration would be
                                             appropriate for picnicking and family activities. The
                                             northern area, which is more heavily wooded, can be a more
                                             passive setting, although there will be a lot of foot traffic
                                             from the parking lot to the beach. Convenient pathways must
                                             be provided here to direct pedestrians away from the secluded
                                             -sitting areas.

                                             could provide a variety of facilities and activities such as a

                                             offices and ranger quarters. Although the recreation center
                                             is currently unprogrammed, the masterplan should identify a
                                             suitable location for it. The illustration shows a 6,000 to

                                  Visual Design and Landscape Enhancement

                                          The visual design/landscape enhan  cement component plays an
                                          important role in accomplishing several objectives.

                                          1.   Vegetation enhancement along the take front     will help to
                                               restore the shoreline.

                                          2.   Wetland vegetation will upgrade water quality and habitat
                                               areas.

                                          3.   Landscape improvements and urban design elements will provide
                                               an attractive setting for the variety-of activities and land
                                               uses surrounding at the lake.

                                          4.   Landscape improvements Will create a naturalistic visual
                                               image or design through planting that visually unifies the
                                               lake's perimeter and surrounding uplands.

                                          5.   Landscaping will help to buffer adjacent land uses and to
                                               integrate new development with the existing context.

                                          CONCEPT

                                          The use of plant materials and landscape design is   the most
                                          important visual element of this plan. The existing and planned
                                          buildings in the vicinity vary widely in use, scale and
                                          architectural character. It would be nearly impossible to develop
                                          a unified visual character using architectural guidelines or man-
                                          made design elements, although some of the small scale commercial
                                          building resorts structures and residential cottages do add
                                          interest locally. Landscape plantings, however, with a
                                          characteristic set of plant species can create a visual identity
                                          that unifies the lake front's variety of conditions, land uses and
                                          activities. This visual design concept also has the advantage of
                                          furthering the water quality, wildlife habitat enhancement and
                                          shoreline restoration objectives at the same time, Also, an
                                          identifiable landscape character can extend into the upland areas
                                          and be incorporated into new development so that the lake's visual
                                          image is integrated in-to the community. For example, the plant
                                          materials on the recommended plant list for grass lined swales
                                          should be installed in new drainage improvements, and the
                                          streetscape zone plant species should be incorporated on all new
                                          street improvements. In addition, the Shoreline Master Program
                                          will call for the submission of a landscape plan to the city for
                                          approval as part of the shoreline permit review. The Master
                                          Program sets standards for the landscape plans that implement the
                                          landscape concept outlined here.

                                          wSIGNATURE PALETTE* OF PLANT MATERIALS

                                          The key to establishing a distinctive landscape character around
                                          Silver Lake is the predominant use of a specific set of plant

                                                                  28

                                        species that create a landscape "signature" for the area. Using
                                        characteristic plant species to create an identity is not a new
                                        idea. The elms and maples lining the streets of New England towns
                                        is aii image we all recognize, and the composer Respeghi celebrated

                                        poem "The Pines of Rome".

                                        The signature palette for Silver Lake builds on the most desirable
                                        of the existing plant varieties found around the take. For
                                        example, white pine is included on the plant list because of the
                                        unusual strands of white pine near the southern wetland area.
                                        Native Plants found in Puget Sound wetlands and lowlands are
                                        emphasized, as are those that will be useful in enhancing the water
                                        quality and wildlife habitats. An example of this is the native
                                        service berry tree which can survive damp areas, has an attractive
                                        flower and provides fruit for song birds. With its naturalistic
                                        appearance, small size, spring flowers and colorful fall foliage,
                                        it is desirable along the footpath, near the. park's new wetland
                                        habitat or in a residential garden.

                                        Because the take front includes a variety of conditions ranging
                                        from emergent wetlands to swales, park open spaces and street
                                        rights-of-way, a plant list has been developed for each "vegetation
                                        zone". Generally speaking, the character of the recommended plant
                                        materials are soft, informal and naturalistic, and they will blend
                                        in effectively with existing vegetation in the park, natural areas
                                        and residential gardens. The results of the landscape concept will
                                        be a subtle but effective backdrop unifying the take's variety of
                                        development features and communicating the message that Silver Lake
                                        is a place where human activity and natural systems co-exist.

                                        LANDSCAPE DESIGN CROSS SECTIONS

                                        The cross sections presented below and keyed to the Visual Design
                                        and Landscape Plan illustrate how the vegetation zones listed in
                                        the signature plant list are incorporated into various stretches of
                                        the footpath.

                                        The first two cross sections illustrate the shoreline restoration
                                        configuration recommended for most of the north and east portions
                                        of the lake.. Because this area receives the most wave action, it
                                        is natural for the shoreline to form in a cove/peninsula formation
                                        with the peninsulas able to extend out into the water because they
                                        are ptotected by either rocks or plants. The coves form in
                                        between the peninsulas where the wave action displaces the sediment
                                        along the shoreline. It is typical for natural sand or gravel
                                        beaches to form in the coves as the peninsulas slow the wave action
                                        and the waters deposit their sediment. Even though the eastern
                                        shoreline is badly eroded, the natural cove/peninsula formation is
                                        still apparent.

                                        Even though badly abused, the lake's eastern shoreline illustrates the natural formation
                                        of coves and peninsulas.

                                                                 32

                                                 The shoreline restoration plan for these areas uses the natural
                                                 tendency by establishing peninsulas of land with fill material and
                                                 anchoring the peninsulas with plant material or rocks. The
                                                 resulting coves are then ideal locations for small wading beaches
                                                 or areas for more delicate vegetation.

                                         The limited wetlands proposed in the north-eastern corner of the
                                         lake are designed to allow open views from the highway and upland
                                         properties, protect the shoreline and provide an attractive setting
                                         for the over-water boardwalk. The boardwalk itself will be a safe

                                         will encourage people to cross SR 527 at crosswalks rather than at
                                         the dangerous curve.

                                  Sectlon 4: Woodland           Park   Walk

                                         The route for both bicycle and foot traffic passes through wooded
                                         glens at the north section of the park. The existing woodland
                                         vegetation will be enhanced and path lighting is recommended for
                                         security.

                                         In the southern wetland areas it is recommended that the trail be
                                         routed back from the water's edge so that the natural functions
                                         such as wildlife feeding and bird nesting not be hampered. The 30
                                         foot access and landscaping easement will, in most cases,
                                         accommodate this concept. Existing native vegetation should be
                                         retained where possible and landscaping for any new development
                                         should emphasize the recommended plant list and enhance the natural
                                         character of the site.

                                                 Where possible, new development and activity centers should be located away from the

                  Comprehensive Planning Vision

                                        Taken separately, each of the individual elements presented in the
                                        previous section will be a significant improvement. But combined
                                        into a unified plan, they will have a dramatic positive impact on
                                        the lake and its surrounding community. If properly coordinated,
                                        the effect of these elements will be much greater than if they were
                                        accomplished separately because many of the recommendations
                                        physically support one another's objectives.

                                        Most urban planning efforts focus on resolving. conflicts between
                                        various objectives and. neighborhood groups. In these normal
                                        planning projects, "trade-offs" are identified and compromise
                                        solutions are sought that equitably balance the benefits to those
                                        who will be affected by the action. In this plan for Silver Lake,
                                        however, the emphasis is on integrating the various objectives and
                                        planning components to maximize their benefit. Wherever possible
                                        priority actions pursue more than one major objective, and
                                        conversely, each category of objectives is advanced by several
                                        interrelated planning components. The chart on the. following page
                                        illustrates how the various improvement actions relate to each of
                                        the major objectives.

                                        This "integrationist" approach is made possible because Silver Lake
                                        is a multi-dimcnsional resource and the planning objectives stated
                                        by the community, developers, the various city departments and
                                        public agencies are not mutually exclusive. To be sure, there are
                                        several areas of controversy, and rapid change such as occurring     in
                                        this area often causes apprehension for the affected parties.
                                        Generally speaking, however, the improvement of environmental
                                        conditions, traffic and infrastructure systems, and public
                                        amenities at Silver Lake is in the interest of developers and the
                                        local community as well as the general public. For example, the
                                        establishment of public access around the lake and the upgrading of
                                        its visual qualities will make new residential developments more
                                        desirable and marketable as well as providing a public attraction.

                                        The two plan drawings on the following pages illustrate the way the
                                        different elements fit together. The first plan schematically
                                        identifies the various improvements while the second illustration
                                        is an aerial plan view indicating the physical qualities envisioned
                                        in the plan. But the aerial renderings present only a portion of
                                        the vision for Silver Lake's future. It is also necessary to
                                        describe Silver Lake's qualities with words to explain its role in
                                        its community, the City of Everett and the south Snohomish County
                                        region.

                                        As envisioned here Silver Lake, in many respects, will be a much
                                        more active, urbane area five to ten years from now. Increased
                                        activity will come from regional development pressures. Many new
                                        housing units will be built in the surrounding area, and these
                                        developments will contribute to amenities that make the new

                                        opportunity for numerous community, educational and recreational
                                        activities. Silver Lake will be urbane in its variety. Visitors,
                                        and local residents will be able to enjoy a leisurely stroll around
                                        the lake that will take them past scenic viewpoints, cafes,
                                        restaurants and community services, small businesses, gardens, tree
                                        lined streets, dense forests and, most probably, by their friends
                                        and peighbors also out for a walk.

                                        But the vision for Silver Lake also demands that the lake retain
                                        its natural qualities. Much of the native vegetation will be
                                        maintained and large portions of the shoreline will be restored.
                                        Wetland habitat areas will be created for wildlife. The lake's
                                        natural landscape character will be enhanced around the new
                                        footpath and extended to street right-of-ways and portions of new
                                        developments, creating a green oasis for south-east Everett. The
                                        same landscaping and wetland improvements will help to maintain
                                        Silver Lake"s water quality by filtering out undesirable nutrients
                                        and pollutants. There will still be opportunities to find solitude
                                        and quiet nearby.

                                        The vision for a lakefront that possesses both an urbane variety of
                                        activities and a naturalistic, heavily landscaped setting is
                                        possible only with a coordinated effort by governmental agencies,
                                        developers and the local community. Each group must understand
                                        that the developmental requirements, public improvements and policy
                                        actions are necessary to effect a better outcome for all.
                                        Fortunately, there are currently many of resources that make the
                                        plan possible. The Everett Department of Parks and Recreation is
                                        supporting major park improvements through bond funds. The
                                        viability of residential development makes access and traffic
                                        improvement requirements feasible. Primarily, however, it is the
                                        natural amenity of the lake itself with its good water quality and
                                        recreational opportunities that is' the cornerstone on which the
                                        pl@li's recommendations are based.

                                        Silver Lake, if this vision is implemented, can be a multi-faceted
                                        civic trcasurc. It will be an ideal an place in the city to take a
                                        swim on a hot summer day, meet a friend, attend a Sunday afternoon
                                        concert, take an after dinner walk, munch on a pizza, hold a
                                        community meeting, paddle a canoe or raise a family. It will also
                                        provide elements of the natural environment for quieter pursuits
                                        such as -nature study, picnicking, fishing, or watching a sunset.

                                                                45

                  Implementation

                                       Implementation of the comprehensive planning vision will resemble
                                       putting together a puzzle because there are many interrelated
                                       actions that must be assembled into a unit. Complicating this
                                       puzzle is the fact that several groups of participants will be
                                       involved in initiating and coordinating each action. The key
                                       participants and their roles in this effort include:

                                       Other public agencies will coordinate with these efforts. For
                                       example, the Snohomish County Parks Department should be involved
                                       where bicycle trail improvements connect to designated County
                                       routes, and the U.S. Army Corps of Erigineers may have some
                                       involvement in management of the vicinity's wetland. In addition,
                                       the local community, including private developers should be
                                       involved in any issue that affects the land use, circulation,
                                       recreational resources, or visual and environmental qualities of
                                       their neighborhoods. The chart on the following page lists the
                                       most important implementation actions, key government participants
                                       and the relative time frames. Although many of the actions can be
                                       pursued independently so long as they do not conflict with one
                                       another's objectives, there are three principal efforts upon which
                                       most of the other projects depend.

                                       are proposed. This will be accomplished by city sponsored

                                     portions will connect back to a public sidewalk until adjacent
                                     segments are developed.

                                     activities is required if additional swimmers and boaters are to be
                                     accommodated. This action is already underway and will be funded
                                     from the 1987 bond levy. Third the first phase of street
                                     improvements must be accomplished in order to ease congestion and
                                     provide greater pedestrian safety. These street improvements
                                     include the construction of sidewalks, a turning lane and signals
                                     on SR 527. The signal is programmed for 1988 and the turning lane
                                     and sidewalk construction will be required as part of private
                                     development projects along the highway.

                     picknicking, informal play and nature study. At the south end of the lake is an
                     ecologically complex wetland habitat with emergent, scrub-brush and forested
                     vegetation zones. State route 527 rings the eastern and northern portions of the
                     shoreline, making the lake itself very visible and accessible to the population in
                     south western Snohomish County.

                     PURPOSE

                     1. To provide public access and the opportunity for the public to enjoy the
                     shoreline by developing a continuous public pathway around the lake which connects
                     park, beaches, piers, habitat areas and other points of interest. The pathway will
                     occur at or near the shoreline edge except at single family residential shoreline
                     lots and will be achieved through a combination of public right-of-way improvements,
                     private easement dedication and site development.

                     2" To enhance public recreational activities by providing public facilities such as
                     picnic areas, habitat settings, fishing and boating docks, etc. that supplement park
                     activities at Silver Lake Park.

                     3. To enhance the environmental quality of Silver Lake and the surrounding area
                     by:
                           a.   Setting site development requirements and mandating improvements that
                                upgrade the Lake's water quality.
                           b.   Setting site development standards that mitigate adverse impacts to the
                                visual, developmental, traffic related and other aspects of the
                                environment.
                           C.   Mandating improvements that enhance the quality of natural vegetation and
                                habitat areas in Silver Lake.

                     4. To enhance the visual character of Silver lake and the surrounding area by:

                           a.   Encouraging the re-vcgetation of shoreline areas with plant materials that
                                are complementary to the area's naturalistic visual character.
                           b.   Visually integrating new and existing development into the naturalistic
                                visual character through standards for landscaping, site improvements and
                                shoreline setbacks.

                     5  To provide an advantageous setting for new development by:
                           1.   Implementating site development standards that will mitigate impacts to

                     The above except ions do not remove the requirements for dedicated public access as
                     described above.
