Stone Lakes National Wildlife Refuge constructed a public-use visitor center
and walking path called Blue Heron Trails in 2011. The construction of Little
Green Heron Playscape, a natural playground for urban Sacramento-area
children, was not completed due to unanticipated expenditures which resulted
in contract renegotiation. The construction company and U.S. Fish and Wildl-
fie Service agreed that Little Green Heron Playscape would not be included in
the new scope of project.
My goals for this booklet...1. Introduce the site and proposed master plan for Blue Heron Trails
2. Expand on several proposed design features for Blue Heron Trails
3. Illustrate the design process of Little Green Heron Playscape
(considered the primary feature of my senior project)
4. Present the construction underway at Little Green Heron Playscape
5. Showcase my passion and skills for landscape architecture
6. Aquire a position that works under a licensed landscape architect

Stone Lakes National Wildlife Refuge
What is Blue Heron Trails?
Refuge Mission StatementThe refuge is dedicated to conserving, enhancing, restoring, and managing Central Valley wetland, riparian, grassland and other habitats to benefit native fish, wildlife, and flora. U.S. Fish and Wildlife Service manages all 6,000 acres of Stone Lakes NWR, striving firstly to restore the land that was once a flourishing stopover area for migrating shorebirds and waterfowl in fall and winter. Blue Heron Wetland and Marsh 6 (left) are boundary man-made wetlands, attracting wildlife and retaining urban stormwater.
Blue Heron Trails (above) is approximately 10 acres with an existing one-mile paved trail; this is the only land acces-sible to the public. Constructed in 2011, this public open area was constructed to fulfill the visitor services require-ments for SLNWR Comprehensive Conservation Plan.

This raised boadwalk carves through the southwestern portion of Discovery Wetland. Tules, the common name for a six-foot water reed, fills this section of the wetland, creating an allee.
Sketchup
The paths are rectilinear, often blocking one’s view to the next turn, producing a maze-like feeling for chil-dren and adults.
One could observe western pond turtles or aquatic garter snakes sunning in pockets of water amongst the dense tle cover. Environ-mental education explaining the benefits of wetlands, especially in regards to carbon sequestration, should be posted at on of the two boardwalk nodes.

Prior to the design of Little Green Heron Playscape, it was essential to submit design considerations for the entire visitor accessible area. The masterplan and tule maze boardwalk are spatially significant to the design to the roposed playscape. School groups regularly attend field trips at Stone Lakes NWR; the amphitheater accomodates up to 300 children.

Little Green Heron PlayscapeDesign Concept Statement
Design Goals1. Create a horticultural learning environment by estab-lishing regionally native and community specific flora
2. Establish a sense of place by manipulating views to avoid unnatural, urban elements
3. Create a space that offers unstructured play for chil-dren with natural elements
4. Offer opportunities for wildlife observation of migra-tory birds in adjacent inaccessible wetlands
5. Spatially organize natural play features in the playscape to accommodate multiple age groups
6. Develop opportunities for environmental education
7. Produce a playground that avoids using prefabricated equipment and pursues natural materials with limited man-made components
8. Design in accordance to federal safety regulations in regards to public open space to support a safe environ-ment for children to play.
Design Concept and Thesis
“Little Green Heron Playscape: a place where children play unstructured, unsigned, and where they’re not told what to do.”
People are losing touch with nature due to limited access to the outdoors, the increased use of technology, and the common parental fears of unsafe adolescent environments. The widespread establishment of natural playscapes can re-engage children, parents, and the public with their natural world by providing unstructured, outdoor recreation.

13It’s okay to play. Little Green Heron Playscapeis a place where children can play unstructuredin a natural environment. Retaining the existinglocation of the playscape, screening the urbanenvironment from visitors, introducing shade, and preserving the existing vegetation were themain factors that produced the design. The spatial arrangement of the many small-scale spaces is optimal for circulation, vantage points,safety, plant species health, and asthenics. Awildlife observation deck is situated atop a man-made hill in order to view nearby wetlands, whichare impossible to view with the existing flat terrain.The topography of the playscape is intricate andcomplex: a concept that can evoke the sensationof viewing an “untouched landscape.” This planis not labeled like the original, however, manyfeatures of Little Green Heron Playscape aredistinguishable. For example, the spiraling brownform composed of circles are vertical logs implanted into a grassy knoll. This play feature is an abstrac-tion of hopscotch. Return to these pages to find the location of features described later in the booklet.

Playscape Planting Vignettes The plantings are organized into different native plant communities, which could be successfully established. The plant profile drawings showcase flora that naturally once thrived throughout the Stone Lakes National Wildlife Refuge.
This planting functions as a screen to block the user’s west-southwest view of alfalfa fields and farm infrastructure. Cottonwoods can be mixed with valley oaks similar to the native road screen. Elderberry and coyote brush are the primary screening plants
Primarily composed of native wildflowers, this section is dominated by california fuschia and poppy, it also showcases sunflowers, grasses, sage, and blue-eyed grass.

Understanding the Observation Platform
It is a goal to increase opportunities for wildlife observation in adjacent wet-lands and marshes. In order to accomplish this goal I increased the elevation of the southwestern portion of the playscape. This large landform is cut soil from future wetland construction nearby. It allow adults and children a rare opportunity for wildlife observation in an urban setting. The platform can educate about sandhill cranes and the protection of migratory birds. The landform is also a play features for children to run up and down or play king of the hill or slide down the subterranean slide. The slope necessary for specific plants in the pollinator garden and forb hillside along the ramp. Moreover, the observation platform serves as a shaded, elevated vantage point where adults can monitor their children.

Stone Lakes National Wildlife Refuge is an important stopover area for migrating shorebirds in the fall and habitat for win-tering waterfowl like Sandhill Cranes, Snow Geese, Canada Geese, and many duck species. Sandhill Observation Deck gives visitors an opportunity to have a unique vantage point to watch the migratory birds set down into nearby Blue Heron Wetland and Marsh 6 each fall and winter.
The raised deck has a wooden seat wall that wraps around a valley oak tree, which offers shade. The overhead structure likewise offers shade. An educational panel on sandhill cranes also blocks the direct view of a transmission tower.
The steep grassy grade encourages chil-dren to race to the top of the hill, play tag, king of the hill, and slide belly down the tunnel log. Grass stains are encouraged!

Sculptural Entry Archway
The entry arch is an iconic thresh-old that children and adults cannotforget. The vertical wooden postsare rough cottonwood trunks and the large beam is an oak trunksalvaged from an underwater sitein Stone Lakes NWR. The cross-road direction sign points to otherRefuges near and far. The cranes,otters, beavers, and dam are brasssculptures.

Croaking Frog CreekThis man-made creek winds throughthe playscape and into DiscoveryWetland. A suction pump is locatedbeneath the entry deck of the play-scape. The creek outflow is covered by a large boulder climbing elementto encourage play and preventtampering.
Nature Art Children are intrigued with play features that are scaled to theirbody size. The space designatedfor nature are in the playscape isenvisioned to be “continuouslytemporary.” As the playgroundmatures, a new nature art featurecould be installed. This sketchillustrates “oak tree trunk frames,”which is a play feature that frameschildren’s faces. Weaving supplewillow branches, which can also befound on the refuge, can createsimilar forms for children tointeract with. This space is createdto hold temporary natural sculptures.
Willow NestA mother watches her sonbalance across a log over CroakingFrog Creek to his sister in thewillow nest. This design featureis an abstraction of a red-wingedblackbird nest, which situates itsnest near a water source, secludedfrom traffic within the bulrush reeds. The nest is surrounded bya swale from which bulrush grow,representing a similar environment.The nest is constructed by weavingsupple willow branches around adonut-shaped form. The featureis depressed into the grade todiscourage pests.

Playscape Construction
Woven willow art wall
Stone Lakes NWR Summer 2014During the last two weeks of my employment with US Fish and Wildlife Service, a public organization dedicated $5000 to contribute towards materials for Little Green Heron Playscape. It was my responsibility to use the allocation, which had to be emptied in 10 days. I purchased boulders for the natural climbing space, Netafim irrigation for the grass berms, and decomposed granite for the proposed pathways. USFWS decided to transfer my last 80 hours of work towards constructing the playscape. This is what I accomplished

About me
Professional Experience
Leaning Pine Arboretum: 2014
My name is Jason Bardeen. I was raised in northern San Diego County, the youngest of three siblings. I attended Cal Poly San Luis Obispo directly from high school after quickly deciding on landscape architecture and horticul-ture to be my profession. After five years I gradu-ated under a department that Design Intelligence ranked the fourth best landscape architecture and design school in the U.S. During the summers, I worked in Sacramento and Elk Grove for Stone Lakes National Wildlife Refuge specializing in irrigation implementation, conservation practices, project management, general maitenance, and practical design solutions.
Design ApproachSome remark that landscape architecture is a profession on its deathbed in this postmodern society. I disagree: landscape architecture is the savior of our sprawling urban environment. It produces connections to public policy, cultural and social progression. Successful design must create a sense of place, nostalgia, and meaning. I am passionate about designing contextually to the site, users’ needs, native flora, and materials. During the design process, I strive to never neglect the unique function, audience, flora, and materials of a place. The professional experience I have accumulated influences me to design with a pragmatisim that favors the reduction of maitenance and durability.
