Active Area:The active area of the park will be comprised of a variety of non-native and native species. These plants will be required to survive the intensity of human traffi c and maintenance. A durable and hearty plant material for this zone is imperative. A high number of the plants in this zone are grass species, and most of the plants in this zone are drought tolerant. The character of this zone is also a low, mounding form with very few trees due to view preservation issues. The forms of these plants are one foot to four feet high with a mounding or upright character. The foliage colors vary from dark green to medium olive and yellow green to a light gray and blue gray. Flower colors tend to be primarily in the blue to purple range. The predominant species in the active zone are ornamental grasses, and have a clumping habit – Carex, Festuca, Muhlenbergia, Nassella and Pennisetum will provide the grassy character of the plating areas. Baccharis, Rosmarinus, Salvia and Westringia will provide the mounding structure for the active areas.

Butterfl y Garden:The butterfl y garden is comprised of plant species who’s primary purpose is to attract butterfl ies. The butterfl y garden is located upon a knoll that overlooks the water. It is a special feature to the park that has a specialized plant palette. The butterfl y garden contains some native species, which are attractive to butterfl ies. The butterfl y garden has been designed to provide seasonal color and interest throughout the year. It is eclectic in nature and resembles a private garden with many fl owering plants. The forms of these plants are diverse, but are predomi-nantly low and mounding. Some plants have an upright form and shape but remain between one foot and three feet tall. The foliage colors in this zone are also very diverse in greens and grays. Flower colors run the gamut of the color spectrum. Seasonal changes to the plants will provide density and color variations throughout the entire year. In addition to being a very colorful array of plants, the butterfl y garden will also provide an array of different fragrances, some releasing odors upon touch.

Streetscape Slope:The streetscape slope plant zone is comprised of all native species, mostly all of which are endemic to the C.S.S plant community. The location of the PCH slope to the existing ESHA areas, make using a native palette desirable way to extend and grow the native habitat area, and create a contiguous CSS zone. The streetscape slope zone is comprised of almost all native species. The non native species are being introduced to provide an edge to the na-tive massing at PCH and the internal park walkways. The streetscape slope zone is comprised of many native spe-cies found in the CSS community. The forms of these plants are low growing in nature, ranging from between one foot and three feet tall, with a mounding character. Forms of the non native species are also low growing shrubs and grasses, to harmonize with the native palette. The foliage colors are gray green, olive and dark green tones. Flower colors range from whites to yellows. Seasonal changes to the plants will provide density and color variations between the winter and summer seasons. Most of the plants tend to be aromatic and the branches soft and fl exible. Characteristic plants of CSS are Atriplex, Enceila, Eriogonum, Opuntia Rhamnus and Rhus. The larger species can eventually grow into small trees – the Toyon, Rhus and Sambucus will provide height relief to an otherwise uniform cover of shrubs. The streetscape slope zone will have a variety of trees planted on the slope, in areas where the trees will not interrupt the view of the adjacent properties.

Overall Park Irrigation Design Narrative:All landscape areas will be permanently irrigated using an automatic, reclaimed water system. The irrigation system will be divided into several sub-systems based on the water requirements of each hyrdrozone. Hydrozone separations are determined by the sun orientation and water requirements of the specifi ed plant material. The ir-rigation system shall be designed to minimize overspray and use an automatic weather-based controller.

Overall Park Conceptual Planting Design NarrativeThe landscape character of Sunset Ridge park has been designed to function as an active recreational facility with fi eld sports, play areas and picnic areas while at the same time, providing a unique setting on the site by reestab-lishing a native Coastal Sage planting into the design. The approximately 13.70 acres of non-active zones of the park, will be designed to support wildlife habitat. The additional acreage of Coastal Sage Scrub (CSS) within the park will signifi cantly expand the area of native habitat to the site. Based on the existing ESHA area, the establish-ment of such a large re-vegetation effort will greatly increase the acreage of viable native habitat for the California Gnat Catcher bird species. In the active, recreational areas of the park the landscape character will blend with the CSS plantings but rely on a wider range plant material to include native and other drought tolerant plant mate-rial that can withstand the rigors of public park environments. The man made landscape will take direct cues from native Coastal Sage community, and will respond accordingly to the site planning, circulation and various interface conditions. The landscape concept is described below, in the various conditions throughout the site.

Expanded C.S.S (Coastal Sage Scrub):The Coastal Sage Scrub zone, is comprised of native species found in the CSS community. The forms of these plants are low growing in nature, ranging from between one foot and three feet tall, with a mounding character. The foliage colors are gray green, olive and dark green tones. Flower colors range from whites to yellows. Seasonal changes to the plants will provide density and color variations between the winter and summer seasons. Most of the plants tend to be aromatic and the branches soft and fl exible. Characteristic plants of C.S.S are Artemesia, Atri-plex, Enceila, Eriogonum, Leymus, Lupinus, Opuntia Rhamnus and Rhus. The larger species can eventually grow into small trees – the Toyon, Rhus and Sambucus will provide height relief to an otherwise uniform cover of shrubs. Supplemental native trees to be introduced in the expanded habitat and residential buffer areas are the California Buckeye, Chitalpa, Manzanita, Scrub Oak and Ceanothus.

Water Infi ltration / Native Buffer:The water infi ltration / native buffer zone of the park, serves a functional purpose by collecting fi rst fl ush run-off in the park, collecting and fi ltering the polluted water, and cleansing the water before it is diverted to the storm water system. The forms of the plants in this zone are low growing and mounding or upright in nature, ranging from one foot to two feet in height. Native species are used in this zone in that the role of the water infi ltration zone is serving a dedicated purpose, and the plant material must be tolerant and supportive of that function. The foliage color of these plants range from dark and medium green to grey and blue green. A select few plants are shrubs, providing accent form and color within the framework of grasses. Flower colors are mostly in the white and cream range with an occasional orange or yellow. Additionally, gravel and large boulders will be utilized for structure and infi ltration function in this zone, and also aid in creating a barrier between the existing ESHA zone and the park. Characteristic plants in this zone are Baccharis, Carex, Encelia, Juncus, Muhlenbergia and Leymus, with Salvia and Eriogonum as accent plantings. Tree plantings will be used in this area, but sparingly. The trees have been selected for adaptation to climate, water and soil adaptability. Tree selection has been made to include evergreen and deciduous species.

Residential Buffer: The residential buffer plant zone is comprised of all native species, mostly all of which are endemic to the C.S.S plant community. This planting zone provides a foreground planting to the adjacent multi-family residential prop-erty to the north, and a backdrop planting to the fi elds and active area of the park. The forms of these plants are low growing in nature, ranging from between one foot and fi ve feet tall, with a mounding character, with two species reaching eight to ten feet tall. The foliage colors are gray green, olive and dark green tones. Flower colors range from whites an blues to yellows and oranges. Seasonal changes to the plants will provide density and color variations between the winter and summer seasons. Most of the plants tend to be aromatic and the branches soft and fl exible. Characteristic plants of the residential buffer zone are Arctostaphylos, Baccharis, Ceanothus, Enceila, Opuntia, Rhamnus and Rhus.. The larger species can eventually grow into small trees – the Rhamnus and Rhus will provide height relief to an otherwise uniform cover of shrubs.
