HISTORY OF THE PARK

TRI CITY PARK MASTER PLAN

Tri City Park has a unique beginnings situated in the communities of Placentia, Fullerton and Brea which, it started out a ranchland owned by Colonel Tuffree. Colonel Tuffree came to Anaheim in 1872 where he is regarded as one of Orange County’s stanch pioneers, settling with his wife in Placentia on their 662 acre ranch, located on parts of the old Rancho San Juan Cajon de Santa Ana. He named their ranch “De Buena Vista”. Colonel Tuffree was very active in the farming community and was one of the original directors of the Anaheim Union Water Company. He was active in the development of bringing irrigation water to Orange County; recognizing farmer’s challenges in transporting water from the watershed locations in the mountains to their fields. Farmers would initially redirect surface water flow, dig wells, build small dams, and often competed for access to river water. Colonel Tuffree suggested a large reservoir, which would allow for water storage, to ensure irrigation water when needed. The Tuffree Reservoir was built on his ranch that helped support irrigation water supplies. In 1875 the first cooperative was formed to share the water amongst the ranchers.The Cajon Irrigation Company was formed by ranchers from Placentia; digging a 17 mile long canal bringing water from the Santa Ana River to Tuffree’s Reservoir. Urban development in the 1950’s and 1960’s led to the reduction of agriculture in the area and the requirement for the reservoir to serve agriculture irrigation needs. In the mid 1970’s the Tri City Authority was created, focused on developing the lake and adjacent land into a public park. The lake which at the heart of the park is stocked with fish, preserves a historical feature of the area for passive use by the community.

A NEW MASTER PLAN

ANALYSIS PROCESS The Master Plan development has been a collaborative process, working with the Tri City Authority, the Tri City Design Committee and the public at large. The process has been relatively quick in starting in October of 2009 and finishing in May of 2010. It was divided into three parts: • Site Analysis Review of the physical, and programmatic project specifics Understanding the community wants and needs for the park

• Concept Development Developement of a concept Plan that integrates park planning, programs and character

• Final Master Plan development The assembly of the concept and park planning into a comprehensive document supported with priority and phasing possibilities for implementations. The documentation of the process, in preparing a conceptual master plan into a comprehensible document to be utilized by the Tri City Authority. GOALS AND OBJECTIVES Goals The goal of the Tri City Master Plan is to provide the Tri City Park Authority (TPA) a complete development vision of a park renovation master plan that will address any and all matters derived from the conclusions of meetings and workshops, directions from the TPA and its advisory committee, and the professional findings and opinions of Mia Lehrer + Associates and their consultants. Objectives • Provide a framework and road map for future restoration, enhancement, and expansion of the park and park programs

• Coordinate and present workshops with the TPA to gather input

• Coordinate and present workshops with the community to gather input

• Compile a complete and comprehensive inventory and analysis of Tri City Park and all of its relating components

• Identify improvements to the lake, parking, ADA requirements, vehicular access, restrooms, Picnic/BBQ areas, play areas, trails, circulation, wildlife, open space, signage, lighting, water harvesting, irrigation systems, drainage, site furnishings, existing vegetation health and succession plan, programs, revenue generation, art, and education

• Prepare master plan document depicting the recommended improvements both in illustrative plan, section, and perspective views as well as written description

• Prepare a recommended priority phasing plan and cost estimates

VISION and strategy The vision of Tri City Park is to retain its passive nature of the park while renovating and updating its character and providing the opportunity for more soft community program activities. The community prefers a light program for this park, preferring to retain the open space lakeside spirit allowing for passive program activities. This park functions as a place to unwind, provide social community interaction, and mild exercise, such as walking around the lake. Fishing is another favorite programmed activity that is specialized to this park. The strategy would be to focus on the more critical items in need of repair, such as, the Lake edge and further develop the rest of site as finances became available that will further enrich the park experience.

REGIONAL CONTEXT & SITE ANALYSIS

TRI CITY PARK MASTER PLAN

SITE ANALYSIS The development of the Master Plan would not be complete without consideration of the existing conditions as a basis to start from. Regional context, neighborhood integration, circulation, site amenities, climate and massing, water features, infrastructure, hydrology, and program analysis studies lead to an opportunity and constraints study to ascertain current park conditions. These potential opportunities focus on the future planning of the park. REGIONAL CONTEXT Tri City Park is an approximately 40 acre site located within three adjacent communities of Placentia, Brea, and Fullerton. Fullerton borders the north and western edges above Rolling Hills Drive; while the park is located within Placentia city limits and is bordered by Placentia along its southern and eastern edges; and Brea located north of Imperial Highway. Each of these communities has residences that utilize the park. The park is more akin to a community park, even though three communities frequent the park. The Tri City Authority is the managing body and is comprised of the cities of Placentia, Fullerton, and Brea. Brea

ROLLING HILLS DRIVE

The park is directly adjacent to residential homes along the northern and western edges. These properties, especially the homes north of Rolling Hills Drive allow for a visual connection within the park and to the Lake. It was discussed adding entrances off of a couple of the cul-de sac neighboring streets into the park, to retain direct access by these local residence, but through the review process it was decided not to advance these concepts but rather limit access onto these streets by non residents that might utilize the local community streets as parking for the park. Kramer Boulevard, a major thoroughfare along the eastern edge of the park, and Placentia residential is east of the boulevard. Tuffree Middle School is directly adjacent along the southern edge. A mixture of school facilities and school athletic fields meet up along this southern edge. Tuffree Hill Park, a slender rectangular park is also along this southern edge. Tuffree Hill Park includes light passive recreation, and a recreational center.

Major vehicular entrances are located off of Kraemer Boulevard and Rolling Hills Drive. Bicycle route access connects from off-site to on-site at these two entrances. Pedestrian entrances also utilize these portals into the park, including a passage from the south through Tuffree Park, from the west through a residential portal and from the north east along Kraemer Boulevard. There is a dirt pathway along the southern edge created by the public and the maintenance crew. The interface between vehicles, bicycles and pedestrian is ill defined at the two entrances, with pedestrians walking in the middle of the street to access the park. The parking is most heavily utilized at the southern and western locations of the park. The largest parking lot is along the southern edge of the park and is heavily utilized by the Tuffree Middle School play fields during sports activities, when parking overflows into this parking lot, and park patrons’ park their vehicles on the open turf areas. The parking at main lot adjacent to the lake is often full while, parking at the most northern location is rarely filled. Parking at the western edge is utilized but infrequently to full capacity. There is no clear delineation of a bicycle route within the park. Community input voiced concerns about the interaction between pedestrians strolling around the park and lake with bikers speeding along the same paths leading to possible collisions.

SITE AMENITIES + RECREATION

TRI CITY PARK MASTER PLAN

N Kraemer Boulevard

The overall park character consists of a mixture of site amenities: benches, picnic tables, drinking fountains, trash cans, bridges, bollards, shade structures, and light poles. The the park has been described as rustic; the materials are predominantly recycled telephone poles and plastic, with a mixture of various materials, finishes and coloration. The benches are hardy recycled plastic trash cans are mounted on posts in the lawn / dirt areas, or plopped in various locations within the park bridges are authentic wood structures in traditional ranch style construction; and the light poles are simple telephone poles with light luminaries mounted on top. There are few buildings in the park, with exception of park restrooms and shade structures. The restroom buildings are simple construction from concrete masonry units with tile roofs; and the interior sink fixtures are stainless steel. It appears that there are no recyclable receptacles within the park. There is an opportunity to design the site amenities into a cohesive kit of parts that will create an overall feeling and strengthen the character for the park.

HABITAT SUMMARY

N Kraemer Boulevard

TRI CITY PARK MASTER PLAN

Based on site visits to the park and conversations with the lake management company, there is a large population of waterfowl that is present in the lake. The most common waterfowl present consists of ducks, geese, coots, and egrets. The number of waterfowl is estimated to be in the 300 to 400 at any given time and varies from season to season. The presence of the waterfowl tempts residents and visitors to feed them. Unfortunately, human handouts to the waterfowl causes their population to easily multiply to undesirable numbers. High waterfowl densities living at a lake contribute to reduced water quality that decreases the aesthetic value and presents a potential public health hazard. According to the US Department of Agriculture, 20 ducks at an average weight of 4 pounds each can produce a nutrient loading of approximately 13 pounds of nitrogen and 4 pounds of phosphorous per year. The nutrient produced can cause significant water quality issues with the lake over time. Additional negative impacts from waterfowl feeding include: • Disturbing of migratory patterns • Over population • Spread of disease • Poor nutrition hinders development • Unnatural behavior in the waterfowl • Devaluation of species • Costly maintenance and management efforts • Water pollution

Mature trees – predominantly Eucalyptus spp. – a fast growing tree type. • Some old Eucalyptus have old wounds. Memorial Trees – not responding well to heavy clay soils. • Special Grove – Daughters of the American Revolution. • In Memorial. Understory is limited to turf and some shrub material at the main restroom and homeowner perimeter planting. Trees planted too low in planting pits. Challenges growth. Very little to no understory under the Eucalyptus trees. Opportunity to enhance entrances to the park. Opportunity for succession planting. Opportunity to introduce water plants.

Growing Season: 8-9 months This regional climate is supportive for a large range of semitropical and temperate plants to grow within. The park has a distinctive landscape character that supports the open space feel of the park; separated into an overstory of predominantly Eucalyptus spp. trees and a barren understory of Bermuda turf as well as dirt areas. The predominant landscape overstory canopy to the north is Eucalyptus spp. and to the south and west is a mixture of tree species. The understory is limited to Bermuda turf and dirt where, very few shrubs are planted located adjacent to the restrooms. It appears that water plants were once planted in the northwest locations of the lake, but are not present today.

Higher amounts of salinity or boron may be present if the soils are to be preleached to reduce the excess or if the plant species will tolerate the salinity and/or boron. Irrigate deeply and reduce the alkalinity, salinity, sodium and chloride where they are high. Preleach prior to planting if the plant palette is sensitive to alkalinity or salinity. Normally irrigate deeply but not frequently. For site maintenance, apply ammonium sulfate (21-0-0) at 5 pounds per 1,000 square feet about once per quarter. Apply gypsum at 10 pounds per 1,000 square feet in about 6 months. Monitor the site with periodic soil testing. Analyze plant tissues as needed for their mineral status. Correct iron deficiency if it develops with Becker Underwood Sprint 138 Fe or other FeEDDHA chelated iron.

WATER FEATURES

TRI CITY PARK MASTER PLAN

N Kraemer Boulevard

Hydrologic and Hydraulic Summary: The site is composed of nine distinct hydrologic subareas. The largest sub-area surrounds the lake and generally occupies the northerly and central portion of the site. The lake sub-area measures approximately 23.0 acres and stormwater originating therein drains directly into the lake by surface sheet flow runoff.

STREAM

Eight smaller sub-areas compose the southerly portion of the site. They range in size from 0.6 acres to 4.2 acres. Stormwater runoff collects at localized inlets contained within each sub-area. The record drawings is inconclusive but suggests that the inlets are connected to an existing stormdrain pipe that enters the park from the east and exits the park toward the south. Water Quality Control Summary: The present day lake is a legacy facility. Decades ago, it functioned as reservoir that supplied irrigation water to surrounding orchards. Over time, urban residential development replaced the orchards making the irrigation use obsolete. Today, the lake is used exclusively for recreational purposes. Irrigation water has been replaced by potable water that is supplied by the GSWC (Golden State Water Company). Any significant modification to the park or lake would involve compliance with the California Water Resources Control Board, Regional Water Quality Board regulations for water quality control of the lake and surrounding property. In the short term, compliance would focus on construction activities.

UPPER LAKE

LOWER LAKE

In the long term, water quality objectives are also mandated by the Board. Regulations seek to maintain and preserve water quality control in the post-construction, long-term operation, and maintenance of any facility or site that may drain stormwater runoff or low flow runoff to an offsite municipal stormdrain or other water body. Compliance is achieved through the preparation and implementation of a Water Quality Management Plan (WQMP). The WQMP would propose various Site Design, Source Control, and Treatment Control Best Management Practice (BMP) recommendations. These recommendations would activate measures to prevent entry of contaminants into the lake such as chemical fertilizers, grass clippings, trash, debris or fecal matter, as repeated introduction of these substances will tend to impair the water quality over time.

TRI CITY PARK MASTER PLAN

REGIONAL RECREATION RESOURCES A five mile radius around the park was used to gather information from other parks within that area. An inventory of existing parks is important to show what may be needed in the community that Tri City Park could accommodate. Ten (10) parks in Brea, twelve (12) parks in Fullerton, and eleven (11) parks in Placentia were included in the five mile radius. The resulting chart shows the abundance of programs at some sites as well as deficiencies. This analysis will assist in developing proposed programs and precedents considered for Tri City Park.

COMMUNITY PLAN

Walking path is flooded in the Morning! Need to walk on Parking lot.

Make part of the park!

Par Course: 10 stations

Structures near perimeter that attract after hours use should be avoided.

Squirrel Holes! Hazard!

Vehicles sometimes drive onto dirt and do donuts! barriers/curb?

Pedestrian Paths separate from vehicular route

Tot Lot Picnic tables

Wasted space Landscaping needed!

Flooding occurs even with existing drains which clog easily

Dirt blows across adjacent homes during high wind

Storage sheds are unsightly + detract from park ambiance

Need greenery + seating around brook

Slippery - Hazard when wetStone or Asphalt?

Water Quality

N Kraemer Boulevard

Consider noise + site lines from nearby homes/streets when placing features

TRI CITY PARK MASTER PLAN

More Fullerton events! Restore landscaping

Bridges collect trash when water flows over rocks

Resurface South Side of Rolling Hills: Bike Access

Utility lines detract from parks natural character!

Improve ADA access to the lake

Lighting needed

Address Bike/Pedestrian safety Brick Wall looks great. Station looks bad - eyesore! Maybe painted?

A clear east-west bicycle route is needed. One that does not conflict with walkers,etc.

Dog Run with exercise features/structures. This area is a dead spot!

1. Lake • Improve Water Quality • Control Lake Fowl – More educational ‘Do not Feed’ signage. • Fish introduced in the lake needs to be larger. • Certain spots in the lake are trash collectors. This needs to be addressed. • The Stream needs to be redesigned. 2. Circulation • Widen and redesign bicycle & pedestrian paths. These need to be better defined and more distinguishable. • Reduce conflict between vehicular, pedestrian and bicycle path users. • Better signage and addition of mile markers on the trails. • Some spots around lake are dangerous & slippery and need to be re-designed. 3. NORTHWEST Area • Large open area is unsafe, unattractive and attracts a lot of riff-raff. • Area is adjacent to residences and they need to be considered when redesigning. • Existing location of storage bins in this area is despised by residents. These need to be relocated elsewhere. • Needs irrigation and new planting. • Some suggestions for potential programs for this area – Frisbee golf, Educational areas. 4. Landscape • More greenery • More trees in NW area

• More green grass • Community garden

5. Programs • Campground • Outdoor cinema • More restrooms • Island for waterfowl • Community programs for teens • Nature talks • Band shell • Improved horseshoe courts • Shade for playgrounds

Picnic structures need Repair/maintenance

Need a cohesive ‘Kit of Parts’ - Pathway lighting - Benches - Trash/Recycling - Bridges - Bollards etc.

High planting all around block wall-including street side.

Key Design criteria • Keep the rustic character of the park. • Keep the park passive and do not introduce buildings or structures including snack shops and restaurants. • The lake is the park’s biggest asset and that should be reinforced in the new master plan. • Add revenue generators such as a coffee shop.

FloodingIrrigation Issues

I think we need a band shell!

• Demonstration garden

• Tot lot • Additional playground • More events • Kiosk for selling coffee, snacks, etc. • Picnic groves • Exercise stations • ADA accessible elements • Farmer’s market

concept The most important objective of the community was to maintain Tri City Park as a passive park supporting community needs. A restraint in design was imperative to maintain the rustic character and maintaining the open space feel. Modernizing the park will bring it up to current and future expectations of energy conservation and revenue opportunities. The overall park layout was kept in tack while moving paths around for better circulation and ADA compliance. New elements such as restrooms and play areas were added as a response to the needs of the community. Revenue opportunities manifested in a lakeside pavilion, café, and improved band shell area. Further improvements considered the existing under-utilized open spaces and designed them to be useable by realigning roads and paths. Lake improvements are many-fold starting with improved water treatment, but also includes edge enforcements and aesthetic enhancements, waterfalls, stream restoration, and inclusion of water planting along the edges and a new dock. All of the improvements will be modern with a simple rustic character. Natural materials such as stone and wood will maintain the rustic feeling that is important to the community. Key Planning Considerations • Maintain rustic / passive character of the park • Clean-up circulation for vehicular, pedestrian, and bicycles • Support healthy, enriching and sustainable landscape • Develop a healthier Lake and Stream and enhance the aesthetics • ADA accessibility • Develop sustainable principles and practices to support park infrastructure, maintenance and safety • Support revenue generation venues that do not take away from the park’s experience or character • Introduction of programs, such as a Discovery Garden or wedding destination area. • Reestablish and enhance existing programs such as a tot lot, picnicking and fishing NeW Area • Create a new program space with Discovery Garden and paths • Add landscape areas • Remove parking lot at north edge

MASTER PLAN

Memorials are an integral part of the park. It has created a personal connection and commitment to the park’s legacy by connecting the community in a very personal and intimate way. The memorials have also created funding opportunities that have allowed the community to participate directly in bringing desired elements into the park. Currently the park has several memorial categories: benches, picnic tables, trees for the Daughter’s of the American Revolution, independent tree memorials, and an independent monument honoring civil engineering. As part of the Master Plan, memorials are an integral park layer and needs careful consideration as the Park enhancements move forward. In order to keep the park fresh, memorial benches will be upgraded predominantly in the same location, with few exceptions. The Liquidambar trees, representing the Daughter’s of the American Revolution are suggested to be relocated to ring the path around the band shell, thus integrating the trees specifically into the landscape design and adding fall color that will enrich the band shell bowl space. The Civil Engineering monument is suggested to be placed on the pier that will better integrate within the park, as opposed to having it casually placed on the grassy slope adjacent to the lake. There are many future opportunities for memorial integration within the proposed Master Plan, but they need to be carefully integrated within the planning of the park. The picnic shelter, benches, picnic tables, café tables and chairs all offer opportunities for public engagement in funding opportunities for the park. A memorial register offers a means for public donations without marking the donations with a plaque that can lead to park clutter or a singular location with donation signing to indicate in a more public way the public commitment and involvement in donations.

PLANTING STRATEGIES Tri City Park has a distinctive plant character that represents the heritage to the area through past plantings of Eucalyptus (Eucalyptus citriodora – Lemon Scented Gum, Eucalyptus camaldulensis – Red Gum, Eucalyptus sideroxylon – Red Ironbark) that creates the tree canopy along the northern and western edge of the park. Most if not all of these trees were planted during the time the lake was the Tuffree Reservoir, or in the1970’s when the park opened. Several decades later these trees are at maximum maturity. Some of the trees have visible scars at their bases. Although the trees overall are full and create a dense shady canopy the understory is barren to mostly dirt. Four factors contribute to the barren landscape below the trees; deep shade, roots filling in potential planting spaces, competition for water and nutrients, and the heavy clay soils. A possible additional consideration is that some researchers indicate that Eucalyptus spp. are allelopathic where chemical compounds from the leaves are leached into the soil that deters germination or makes other plantings compete for natural resources in order to survive. Other mature trees include a mixed forest of conifers such as Pinus halepensis (Aleppo Pine), Pinus pinea (Italian Stone Pine), some native trees, Quercus agrifolia – Coast Live Oak, Alnus rhombifolia – White Alder, and Platanus racemosa – California Sycamore. There are three groups of additional specialized heritage / memorial trees: Heritage Citrus Trees – representative of the orange groves of southern California, and the Liquidambar styraciflua – American Sweet Gum – to memorialize the Daughters of the American Revolution, and a third memorial of a tree or two at the north end of the park. The balance of the trees will be a mixture of types common to the southern California region. The understory throughout the park is non-existent with exception of a few patches of grass in the sunniest locations of the park and to the far southeast corner of the park. Overall Landscape Strategy for the Park: • Create a landscape succession plan for the park as trees reach a maximum age and decline so that other trees are planted to become the future tree canopy for the park. • Consider expanding the existing Citrus trees to represent the agricultural past of the Tri City area, focusing future Citrus planting in the Northeast corner of the Park. • Consider moving the memorialized Liquidambar trees to be integrated as part of the park spatial framework. Currently they seem to be planted loosely without any emphasis. • Create a landscape understory where appropriate to add interest to the landscape. Also create a habitat to enrich the fauna population of the park. Enhance key features of the park without taking away the safety and security of the park. Emphasis of understory planting. o At entrances and park nodes o Buffer zone between the neighboring properties and the park o Lake edge – Control waterfowl population, add in water treatment for stormwater run-off, and landscape aesthetics. o Screening around water reclamation facility o Integration at key circulation areas to focus and separate circulation and enhance the landscape experience o Special garden planting layer at the stream and the community garden

TRI CITY PARK MASTER PLAN

• Create a garden experience and opportunities within the park to add program value for visitors • Turf areas are important to the park to allow for open space that is much appreciated by the visitors. It allows for flexible programs and special events. and should be retained in key park locations • Suggested plant palette for the succession plan for the Park:

Tree selection candidates:

California indigenous: o Quercus agrifolia (Coast Live Oak) o Quercus engelmanii (Pasadena Oak) o Alnus rhombifolia (White Alder) o Platanus californica (California Sycamore) o Ulmus californica (California Bay)

Significant California Horticultural trees: o Eucalyptus citriodora (Lemon Gum) o Eucalyptus sideroxylon (Red Iron Bark) o Eucalyptus camaldulensis (Red Gum) o Schinus molle (California Pepper) o Agonis flexuosa (Peppermint Willow) o Pinus pinea (Italian Stone Pine) o Pinus halepensis (Aleppo Pine) o Fagus sylvatica ‘Purpurea’ o Nyssa sylvatica (Tupelo)

It is acceptable to continue to plant the Eucalyptus spp. as long as thoughtful forestry practices are implemented and the timing of planting is staged to ensure health..

Heritage Trees: o Citrinus sp. ‘Valencia’ (Valencia Orange)

Memorial Trees: o Liquidambar styraciflua – planted with emphasis and distinction

SUCCESSION CONCEPT

MASTER PLAN

N Kraemer Boulevard

Aleppo Pine (Pinus halepensis) – Pines provide a valuable evergreen tree type, and should be accessed during the years on their general health. Both Aleppo Pine – Pinus halepensis, and Italian Stone Pine – Pinus pinea are two good pine types. American Sweet Gum (Lyquidambar styraciflua) – The dynamic fall leaf color of the these tree provide an accent in the fall. The suggestion is to relocate and plant new American Sweet Gum trees along the walkways surrounding the band shell location which will create an outdoor landscape room for future concert venues. Sycamore (Platanus racemosa) – The Sycamore is the most dominant deciduous tree at the park. The Trees adjacent to the Lake should remain Sycamores as they provide a cohesive planting along the Lake edge. Trees to the south in the future succession planting can be a combination of two riparian types of California Sycamore – Platanus racemosa, and White Alders – Alnus rhombifolia California Pepper (Schinus molle) – Try to retain these trees in their existing location as long as possible. These trees mature into specimens over the years. Careful consideration in water management and care should be focused on these trees. Plant younger trees in the Park at key accent locations to support a succession plan in retaining these trees well into the future.

NOT TO SCALE LONG TERM SUCCESSION

Jacaranda (Jacaranda mimosifolia) – A park flowering accent tree focused at the entrances and general lawn areas of the Park. Additional trees to compliment the Jacaranda are Albizia julibrissin - Silk Tree, Cassia leptophyll – Gold Medallion Tree, and Koelreuteria paniculata – Goldenrain Trees.

Lemon Scented Gum (Eucalyptus citriodora) – The Eucalypus spp. forest is at maturity. Future planting of young Eucalyptus and other native planting of Coast Live Oak – Quercus agrifolia, Sycamore – Platanus racemosa, and White Alders – Alnus rhombifolia would support a sustainable forest for the future. Succession Tree planning should be implemented on a 15 year planting cycle. Due to the maturity of the current park forest, it is suggested to review initially on a five year cycle period for the first fifteen years, to initiate an effective succession cycling of tree planting that has long been neglected. Orange (Citrus sp. ‘Valencia’) – Move citrus grove to the northeast corner of the park, and establish an orchard lay-out. Red Gum (Eucalyptus camaldulensis) – The Eucalypus spp. forest is at maturity. Future planting of young Eucalyptus and other native planting of Coast Live Oak – Quercus agrifolia, Sycamore – Platanus racemosa, and White Alders – Alnus rhombifolia would support a sustainable forest for the future. Succession Tree planning should be implemented on a 15 year planting cycle. Due to the maturity of the current park forest, it is suggested to review initially on a five year cycle period for the first fifteen years, to initiate an effective succession cycling of tree planting that has long been neglected. Evergreen Trees (Mix) – Evaluate on a regular basis the evergreen tree health, replant with same plant types, including Coast Live Oak – Quercus agrifolia, Brisbane Box – Pittosporum undulatum, and Peppermint Tree – Agonis flexuosa Deciduous Trees (Mix) – Evaluate on a regular basis the deciduous tree health. Replant with same plant types, including White Alders – Alnus rhombifolia, Cape Chestnut Calodendrum capense, Chinese Fringe Tree – Chionanthus retusus.

The signage is created not to call attention to itself, but rather, be blended within the landscape. A cohesive design and consolidation of park signs will aid the public in knowing where to look for information when they need it. Also instrumental to the sign program are interpretive signs that will educate the public on the waterfowl and lake. The materials are natural wood with embossed lettering,. Colors for the interpretive and park information signs evoke the natural colors of the park in olive greens and blues. The font is clean and friendly, further reinforcing the updated fresh look for Tri City Park.

TRI CITY PARK MASTER PLAN

The hardscape materials are simple and evoke a passive contemporary rustic character for the park, also keeping in mind sustainable practices, maintenance and operations. The park’s internal road is constructed of asphalt. The parking lot paving will be converted to permeable concrete paving. The extensive park paths will be colored asphalt, with secondary paths constructed from decomposed granite. The tan colors focusing on the more golden earth tone coloration for the park. Resilient rubberized paving is slated for the play areas and rock climbing zone, that allows for an artistic playful graphic to be interpreted in the floor paving. Walls will be made of local stone, supporting the regional character of this park. There is limited fencing supporting the open and inviting feel for the park. The planning could include a park vehicular swing gate that would control after hour usage of the park when it is closed. The Discovery Play Area is to be playful, fun, and pedagogical; emphasizing the history of the three cities represented in the park focused on the railroad, citrus and oil.

LIGHTING PLAN

N Kraemer Boulevard

TRI CITY PARK MASTER PLAN

The overall lighting scheme will create a more cohesive illumination for the park at night. Lighting for Tri City Park is divided into zones from brightest to darkest. The emphasis with the lighting is to be supportive of a pathway lighting based system, placing the light only where it is needed. The brightest locations are within the parking lot and become attenuated along the pedestrian pathways. In limited locations, for example, adjacent to the path leading to the Discovery Play area are short waist high bollards that are motion based, only turning on when approached; therefore, creating a lighting magical experience, and a reduction in energy consumption and cost for the park. The bikeway path is not lit, reducing the lighting intrusion into the neighboring properties. Accent lighting is to be incorporated in the shade structures, and on the lake side pier structures. Restroom lighting is planned also to be motion sensor based, supported with an override for special occasions. Pole lighting made of tapered wood, dark sky compliant luminaires, will support the lighting needs at night, while adding a contemporary addition to the park amenities and site furnishings during the day.

ART

TRI CITY PARK MASTER PLAN

The inclusion of art within the park will enrich the park experience and support regional art and culture. The expression of art can be woven as part of the park fabric and take many forms, such as sculptural as indicated in the suggestive images. It can also be playful and be incorporated into park programming, such as at the Discovery Play Area. The park pathways support movement throughout the site, and therefore, creates many opportunities for art discovery.

CONCLUSION

MASTER PLAN

CONCLUSION The Tri City Master Plan is a positive step in renovating a valuable asset for the local communities. Extensive Inventory and Analysis gave the design team and the Tri City Park Authority as much of a background of the park as possible. Opportunities and precedents were reviewed giving the design team a direction in developing two alternatives. Improvements include the lake refurbishment, revenue generation, pathways/circulation, parking, signage, education, play areas, picnic shelters, restrooms, site furnishings, lighting, maintenance, and planting succession. After further community and Tri City Park Authority gatherings, the two alternatives were combined to one for further development. As the Tri City Park Authority reviewed the final development plan, the design team continued to refine and detail the master plan so that, if implemented, much of the framework will have already been completed. The presentation of the Master Plan signifies the end of this phase but the beginning of exciting renovations of a piece of cherished, historical park land.

LAKE HISTORY

TRI CITY PARK MASTER PLAN

TRI CITY LAKE HISTORY The Anaheim Union Canal, begun by the Cajon Ditch Company in 1875, was an improvement of the original system of hand-dug earthen ditches that ran approximately 10 miles westerly from Santa Ana Canyon to the Tuffree Reservoir and was completed in 1879. The system of canals and ditches was eventually lined with concrete to reduce infiltration losses. In 1884 the Anaheim Union Water Company (AUWCO) was formed by a consolidation of four prior ditch companies, including the Anaheim Water Co., the North Anaheim Canal Company, the Cajon Irrigation Co. and the Farmers Ditch Co. Diversion works for the AUWCO Irrigation System were located at “Bed Rock Crossing” of Santa Ana Canyon, near the easterly Orange County line. One-half the river flow was diverted northerly from that location while the remaining half was diverted southerly by SAVI (Santa Ana Valley Irrigation) from a location about 1 mile downstream. “Yorba Dam” was constructed in 1907 adjacent the main canal. The dam is 46 feet high with approximately 1,000 acre-feet storage and with connections to lower irrigation ditches. AUWCO’s longtime manager Leo J. Sheridan, in a written history after his retirement in 1953, reported that the company at its historic peak served irrigation water to approximately 8,500 acres within a district of 14,949 acres. Rapid urban development during the 1950s and 60s requiring municipal water and sewer services superceded agricultural land uses, reducing demand for untreated irrigation water, and the company was dissolved in 1970. Yorba Dam was decommissioned as an irrigation reservoir and is now owned and operated as a flood detention basin by the Orange County Flood Control District. Tuffree Reservoir, which is below the level of jurisdiction for the State Division of Dam Safety, has been preserved as an aesthetic water feature known as Tri City Park in the City of Placentia. (See Figure 1) The park is managed between the cities of Brea, Fullerton, and Placentia since 1975.

THE LAKE AND SURROUNDING LANDSCAPE RUNOFF

APPENDICES

Using aerial photos and field verification during our site visits, we determined that Tri City Lake is approximately 7.1 acres. The average depth is approximately 6.0 feet and the volume is estimated to be approximately 14.0 million gallons. Currently the lake is filled through a metered potable water source (See Figure 2). The lake is surrounded by a sloped landscape that creates a watershed area of 249,650 square feet. The runoff area is roughly the entire area on the lake side of the perimeter pathway that circles the lake. (See Figure 2) To quantify the runoff, the team used the Resources and Development Management Department (RDMD) precipitation records, during a typical 2 year storm event; the highest average runoff level for a one month period is approximately 3.55 inches yielding a volume of about 1.69 acre feet.The runoff is currently uncontrolled and contains unwanted pollutants from droppings of the many types of waterfowl living around the lake. Rerouting the runoff to enter the lake at various water quality filters along the lake edge would allow natural treatment of the runoff. (See Figure 3) A water quality filter is a wetland planter where storm and nuisance runoff is conveyed for treatment. These water quality filters should be designed so that any water that enters them have a specific retention time for treatment prior to it overflowing and discharging to the main water body of the lake.

WATERFOWL / WATER QUALITY

TRI CITY PARK MASTER PLAN

WATERFOWL The lake is populated with various types of waterfowl. The estimated population based on information from the city’s staff is:

Ducks: 50-60 Coots: 200-300 Geese: 30-40 Egrets: 5-7 Swans: 3-5

The waterfowl population can increase and decrease during the year. However, the lake is usually dense with waterfowl creating an unhealthy environment for both waterfowl and humans. Negative effects Currently the large population of ducks, geese, and coots can have a negative impact on lake water quality. An average 4 pound duck contributes 2/3 pounds of nitrogen annually and ¼ pounds of phosphorus annually. Large populations increase the chance of avian botulism. (See Figure 4).

FIGURE 4

Feeding of Waterfowl Feeding of the waterfowl increases the population of the waterfowl (See Figure 5). Along with this obvious problem, feeding the waterfowl is harmful to their survival and instead of helping the animals; people inadvertently harm them in the following ways:

a. b. c. d. e.

Migratory pattern is disturbed Creates dependency of waterfowl to humans Poor nutrition hinders proper development of water fowl Geese graze on lawns Spread of disease

By educating the public on the negative effects of feeding the waterfowl and enforcing a no feeding policy, the population can be reduced along with changes to the shoreline. Installing the water quality filters at the shoreline along with water planter areas, entry to the lakes will be diverted.Waterfowl does not inhabit bodies of water that have shoreline access impeded by obstacles. By relocating some waterfowl and deterring their population growth, the water quality will be much improved and the landscape adjacent to the lake will improve as well.

FIGURE 5

WATER QUALITY The lake was tested on October 15, 2009 and March 4, 2010. Samples were taken at the upper and lower lakes near the surface and at 3.5 foot depths. Preliminary results show the water to be acceptable for use as irrigation but additional testing for Boron and Sodium vs. Manganese would further validate these findings. Water Testing During the initial site visit, water samples were taken from the lower and upper lake and testing was done for the following critical constituents: Dissolved Oxygen, Total Suspended Sediment, Nitrogen, Phosphorus and pH. The following is a summary of these findings. Dissolved Oxygen (DO) The DO determination measures the amount of dissolved (or free) oxygen present in water. Aerobic bacteria and aquatic life such as fish must have DO to survive. Water treatment facilities such as ponds and lakes depend on these aerobic bacteria to treat sewage. This process occurs naturally in streams and ponds if organic matter is present, turning these bodies of water into “aerobic wastewater treatment plants.” If sufficient oxygen is not supplied naturally through wind and turbulence, or artificially through aeration, to replace the depleted oxygen, the body of water will develop a low DO and become anaerobic (or septic). The results of septic water bodies include fish kills and anaerobic odors. The DO test is used to monitor the process to ensure that there is enough dissolved oxygen present to keep the process from becoming septic. Lake standard levels of DO are greater than 3mg/L. The test result for Tri City Lake was 8.21 mg/L, well above the standard. Total Suspended Sediment (Turbidity) Excessive turbidity, or cloudiness, in water is aesthetically unappealing, and may represent a health concern. Turbidity can provide food and shelter for pathogens. If not removed, turbidity can promote re-growth of pathogens in the distribution system, leading to waterborne disease outbreaks, which have caused significant cases of gastroenteritis throughout the United States and the world. Although turbidity is not a direct indicator of health risk, numerous studies show a strong relationship between removal of turbidity and removal of protozoa. Lake standard levels of Turbidity are less than 3mg/L. The test result for Tri City Lake was 5mg/L, above the standard and expected given the appearance of the lake.

WATER QUALITY

APPENDICES

Nitrate (as NO3) 1. Nitrogen is an element needed by all living plants and animals to build protein. In aquatic ecosystems, nitrogen is present in many forms. Nitrogen is a much more abundant nutrient than phosphorus in nature. It is most commonly found in its molecular form (N2), which makes up 79 percent of the air we breathe. This form however is useless for most aquatic plant growth. Blue-green algae, the primary algae of algal blooms, are able to use N2 and convert it into forms of nitrogen that plants can take up through their roots and use for growth: ammonia (NH3) and nitrate (NO-3). As aquatic plants and animals die, bacteria break down large protein molecules into ammonia. Ammonia is then oxidized (combined with oxygen) by specialized bacteria to form nitrites (NO-2) and nitrates (NO-3). These bacteria get energy for metabolism from oxidation. Excretions of aquatic organisms are very rich in ammonia, although the amount of nitrogen they add to waters is usually small. 2. Sources of Nitrates-stormwater runoff can carry nitrate-containing fertilizers from surrounding lawns into waterways. Similarly, places where animals are concentrated produce large amounts of wastes (from excrement) rich in ammonia and nitrates. Duck and geese, are large contributors in areas where they are plentiful. If not properly contained, these can seep into groundwater or be transported in runoff into surface waters. 3. Lake standard levels of Nitrate are less than 1mg/L. The test result for Tri City Lake was 1.6mg/L, above the standard. The high content is expected given the population of geese and ducks.

pH Levels 1. pH is a measure of the acidity of alkalinity of water, expressed in terms of its concentration of hydrogen ions.The pH scale ranges from 0 to 14. A pH of 7 is considered to be neutral. Substances with pH of less that 7 are acidic; substances with pH greater than 7 are basic. 2. When pollution results in higher algal and plant growth (e.g., from increased temperature or excess nutrients), pH levels may increase, as allowed by the buffering capacity of the lake. Although these small changes in pH are not likely to have a direct impact on aquatic life, they greatly influence the availability and solubility of all chemical forms in the lake and may aggravate nutrient problems. For example, a change in pH may increase the solubility of phosphorus, making it more available for plant growth and resulting in a greater long-term demand for dissolved oxygen. Generally, during the summer months in the upper portion of a productive or eutrophic lake, pH will range between 7.5 and 8.5. In the bottom of the lake or in less productive lakes, pH will be lower, 6.5 to 7.5. 3. Lake standard levels of pH are between 7.5 and 8.5.The test result for Tri City Lake was 8.7, above the standard range and indicating algae growth which consumes carbonic acid and drives up the pH levels.

Treatment of runoff and management of water quality relies on re-creation of the natural chemical and biological processes within the lake system resulting from a unique combination of different layers of treatment.(See Figure 6) The recommended general treatment processes for the different target pollutants include: 1. Filtering suspended solids in pretreatment wetlands. 2. Reduced concentration of dissolved pollutants, nutrients, and salts through flushing of the lake water volume by utilizing the lake as the irrigation supply source. 3. Reduction of nutrient concentrations from inflows, Nitrogen and Phosphorous, and prevention of algal blooms by using constructed gravel biofilters bed that relies on â&#x20AC;&#x153;biological filtration.â&#x20AC;? 4. Maintaining oxygen levels through aeration promoting oxygen exchange to prevent anaerobic conditions which allows natural process to occur such as denitrification for removal of nitrogen. 5. Removal of BOD (Biological Oxygen Demand) and heavy metals through wetland planters. 6. Collection of large sediments and floating debris at centralized outfall boxes to the lake system with debris collection facilities and sediment traps. 7. Pretreatment and primary control through wetland water quality filters designed as attached-growth biological reactors.

Total Phosphorus 1. Phosphorus is one of the key elements necessary for growth of plants and animals and in lake ecosystems it tends to be the growth limiting nutrient. The presence of phosphorus is often scarce in the welloxygenated lake waters and importantly, the low levels of phosphorus limit the production of freshwater systems. Unlike nitrogen, phosphate is retained in the soil by a complex system of biological uptake, absorption, and mineralization. Phosphates are not toxic to people or animals unless they are present in very high levels. Digestive problems could occur from extremely high levels of phosphate. The soluble or bio-available phosphate is then used by plants and animals. The phosphate becomes incorporated into the biological system. 2. Sources of Phosphates include: natural decomposition of rocks and minerals, stormwater runoff, agricultural runoff, erosion and sedimentation, atmospheric deposition, and direct input by animals/ wildlife. 3. Lake standard levels of Total Phosphorus are 0.02 mg/L.The test result for Tri City Lake was 0.73mg/L, above the standard.

FIGURE 6: Lake Treatment

BIOFILTERS

TRI CITY PARK MASTER PLAN

The biofilters are typically 3 to 4 feet deep, filled with gravel media and submerged 18 to 24 inches below the lake water surface. The media provides attachment sites for activated biomass used for nutrient removal. A perforated herringbone piping network will be located beneath the media for distributed water flow upward through the media for biological treatment and physical filtration. Water will be pumped through the piping network from the recirculation system pumps (see Figure 7). Similar to a wastewater treatment nutrient removal filter, the custom gravel media biofilter is capable of high rate biological organic carbon consumption and denitrification (nitrogen conversion and removal) as compared to wetlands. Combined areas of aerobic and anoxic conditions in the biofilter, particularly on the biological flocs, provide an ideal environment for aerobic BOD reduction and nitrification and anoxic nitrate reduction. In addition, phosphorus removal via physical filtration and biological uptake has been shown in the biofilter. Coliform, an indicator of pathogens, may be effectively removed by biological predadation in the media biofilters. A specific recommendation for biofilters for the Tri City Park Lake is included later in this report.

FIGURE 7: Biofilter

APPENDICES

AERATION

Currently Tri-City Lake is not aerated. Warm air temperatures in the spring and summer may cause the upper layer(s) of the lake to become warmer than the ambient lake temperature. The warmed upper layers become temporarily separated from the cooler lower layers due to density differences. Sediment and lake oxygen demand on the lower layers deplete oxygen, which has no means of replenishment as it is separated from the atmosphere until the following autumn. Dependent on oxygen for respiration, fish and other aerobic biology must leave this region to avoid suffocation. Providing compressed air to the bottom of the lake provides multiple means of the replenishing depleted oxygen. Introducing oxygen in the form of air at the bottom of the lake is achieved via 1) direct oxygen transfer from aeration-pod diffusers (see Figure 8) and 2) destratification of top and bottom liquid layers.The top of the lake (epilimnion) is exposed to the atmosphere where oxygen is transferred into solution; destratification mixes water from the epilimnion with the typically lower-oxygen hypolimnion layer. In addition to the obvious lake benefits of enhanced conditions for lake biology, specific metals are less toxic and less bio-available when oxidized. Limiting nutrient phosphorus tends to remain in its solid state in lake sediment and does not dissolve efficiently under the presence of oxygen. Oxidized conditions within the lake column are important for aesthetic reasons. In aerobic conditions odorous compounds such as gaseous sulfur and methane will be reduced. Sulfur typically remains in a precipitated state in lake sediment under the presence of oxygen. Methane may be produced by biological fermentation under anaerobic (reduced or non-oxidized) conditions. In addition, the solubility of iron and manganese is significantly reduced under oxidized conditions.This will function to enhance water clarity and color.To take advantage of the many benefits of aeration mentioned in this section, PACE recommends that aeration be provided via a fine bubble diffusion system placed at the bottom of the lake.

FIGURE 8: Aeration Pod

SEEPAGE TESTING

TRI CITY PARK MASTER PLAN

Evaporation Pan VS CIMIS

Inches/Day

A seepage test was conducted from February 18th to March 10th 2010. During this period PACE was able to use 7 days of data that was precipitation free. The level of the lake was monitored during the testing period and an evaporation pan was located at the City of Placentia City Yard. Using this collected data and comparing it with data collected from the California Irrigation Management Information System (CIMIS), PACE was able to verify that the collected data is valid. There are studies that show that evaporation is equal to evapotranspiration. For this testing, we used evapotranspiration numbers for evaporation. Figure 9 shows the losses in the evaporation pan at the project site and the closest CIMIS weather station. Even though there is a discrepancy in the losses the trend for both is consistent. The discrepancy is due to the distance between the Irvine weather station and the project site location. By comparing the data from the evaporation pan and the changes in the lake level, we can determine the estimated losses due to seepage by subtracting the pan losses from the lake losses (See Figure 10).

CMIS (Irvine)

Vertical Loss in Pan Day FIGURE 9: Evaporation Pan VS CIMIS

To determine the losses in the lake due to seepage, we subtract the vertical losses from the evaporation pan from the vertical losses measured from the lake. From the test results, it appears that the vertical drop from the lake is greater than that of the evaporation from the pan. The difference could be attributed to seepage losses through the liner of the lake. The average change in the lake level over the 7 days of data collection was .26 inches and the average change in the evaporation pan during the same period was .13 inches. The difference between the two tests for the 7 days of data is 0.26”- 0.13”= 0.13”. That is approximately 0.13”/day differential accountable towards seepage through the soil liner (See Figure 11).

Vertical Inch Losses

The acceptable permeability of soil lining systems is typically 1x10-7 cm/sec.

SEEPAGE TESTING

APPENDICES

We The acceptable permeability of soil lining systems is typically 1x10-7 cm/ sec. Darcy’s Law was used to approximate the seepage rate through soil for the system. Darcy’s Law is:

Q= K*i*A • • • •

Q = Flowrate K = Coefficient of permeability i = hydraulic gradient where i=h/l, h is the average depth and l is the thickness for the lining system A = Area

To determine the seepage rate (K=Q/A*i), the following assumptions were made: The thickness of the lining system is between 6” and 12”, l The average depth of the lake is 6’, h. With Q/A=0.13”/day, h=6’, l=6” to 12”, the permeability of the lining system was between 3.18x10-7 cm/sec to 6.37x10-7 cm/sec. Per the Permeability Conversion Chart (See Figure 12), this is in the practically impervious range to very low permeability range.

FIGURE 12: Permeability Conversion Chart (courtesy of John Wiley & Sons, Inc.)

At .13”/day, the amount of water lost for the 7.1 acre lake due to seepage would equate to approximately 25,275 gallons per day. The soil seepage rate of .13”/day is within an acceptable seepage rate range for a typical soil lining system. The seepage rate was taken during the month of March when Southern California was experiencing heavy rainfall. The ground adjacent to the lake was saturated and could possibly have had a high ground water level. With a high groundwater elevation, the amount of seepage will be reduced since there are no hydrostatic forces forcing water out of the lake and into the ground. For the purpose of this master plan, we would recommend that additional geotechnical studies be conducted to determine the ground water elevation. The historical ground water level needs to determined if more water is being lost due to seepage. Ideal seepage testing should be done in the dry summer months.

WATER BALANCE SUMMARY

TRI CITY PARK MASTER PLAN

Due to the continual and daily nutrient loading occurring in lakes (from various sources including birds, landscaping, urban runoff, etc.) and the subsequent difficulty in maintaining low concentrations of nutrients which contribute to poor water quality, using the lake water for the irrigation water and replacing the lake water with makeup water from the potable source will increase the water quality. The following graphs reflect the various water balance for all proposed lake configurations and the existing lake configuration. The first table compares data from water losses due to evaporation and seepage using data from 2007 and 2008 for precipitation, evapotranspiration, and Tri City Park Water Use records from for 2007 and 2008 (See Figure 13).The comparison of the two sets of data is used to validate our results in the following water balance charts. We calculated the water lost taking into account all the inputs and outputs going in and out of the lake as well as what was used for irrigation. The soil lining seepage is based on our testing in March 2010.The existing irrigation data was provided by d.d. Pagano, Inc. Irrigation Consultants. Figure 13 indicates that the calculations used for water use in 2007 and 2008 are near that of the actual water used based on meter readings. There was a 5% and 5.5% discrepancy between 2007 and 2008 results respectively in the actual amount of water used and the calculated results. FIGURE 13: Demand vs. Actual Use

FIGURE 14: Lake Demands with Various Conditions

This next table shows the various demands for each condition (See Figure 14). These values are for Lake demands only and do not include water use for irrigation taken from the water supply. All values are using the 2008 records as discussed previously. Water losses either through seepage or naturally occurring evaporation will be replaced with water from the supply line.When using the lake water for irrigation we increase the amount of water we are taking from the lake and replacing with water from the potable water supply line. Using lake water for irrigation increases the turnover rate for the lake. PACE recommends lake water to be turned over at least once every 90 days. If a turnover rate of less than or equal to 90 days cannot be achieved, PACE recommends installation of Biofilters to create an appropriate turnover rate (See Figure 15).

WATER BALANCE DATA

Existing Condition-Irrigation with Water Supply 2007 The water balance for the existing lake using the 2007 data shows the demand of 125 acre-feet of water and the metered use of water at 132 acre-feet. (See Figure 16) This difference could be attributed to the unknown water seepage during the summer months when the assumed water table is low or to over irrigation of the park landscape. The net demand of water and the recorded meter reading for the 2007 existing condition shows a difference of water use of 7 acre feet of water.

FIGURE 16

WATER BALANCE DATA

TRI CITY PARK MASTER PLAN

Existing Condition-Irrigation with Water Supply 2008 The water balance for the existing lake using the 2008 data shows the demand of 120 acre-feet of water and the metered use of water at 127 acre-feet. (See Figure 17) This difference could be attributed to the unknown water seepage during the summer months when the assumed water table is low or to over irrigation of the park landscape. Comparing the results of 2007 and 2008 (see Figure 17) we find that the water demand versus water use was the same. The similarity of water use validates our data for use with the following optional conditions. The lake demand of 51 acre-feet per year requires that the lake be replenished with the supply water. This will turnover the water in the lake every 307 days. The turnover rate for this option is higher than the recommended 90 days. Biofilters are recommended to increase the turnover rate to acceptable levels. The net demand of water and the recorded meter reading for the 2008 existing condition shows a difference of water use of 7 acre feet of water.

WATER BALANCE DATA

Proposed Condition: Using Lake Water for Irrigation, Existing Liner The water balance data for this condition uses the 2008 data mentioned earlier. (See Figure 18) By using the lake as the source of the irrigation water, the lake water can be replaced with the cleaner potable water from the water supply. As lake water is replaced with the cleaner water, the lake water quality will be improved. The proposed net demand from the lake is 141 acre feet. At this rate, the lake will turnover every 111 days.The seepage rate for this table remains at .13 inches per day. The turnover rate for this option is higher than the recommended 90 days. Biofilters are recommended to increase the turnover rate to acceptable levels. Using the Golden State Water price of $2.23/CCF, The cost of the net demand of water for this condition is $136,965 per year. Possible higher seepage losses during the summer months will increase the water losses.

FIGURE 18

WATER BALANCE DATA

TRI CITY PARK MASTER PLAN

Proposed Condition: Irrigation from Water Supply, PVC Liner The water balance for the proposed PVC lined lake using the 2008 data shows a decrease in demand per month. (See Figure 19) The PVC liner has a typical water loss of .011 inches per day. PVC liners historically are not effective in high ground water areas. A geotechnical report must be done before any decision can be made for the lake lining system. The proposed net demand from the lake is 118 acre feet. At this rate, the lake will turnover every 133 days. The turnover rate for this option is higher than the recommended 90 days. Biofilters are recommended to increase the turnover rate to acceptable levels. The 2008 existing condition turnover rate of 307 days (See Figure 17) compared to the 132 days for this condition reflects a difference in the seepage rate. This is attributed to the almost impervious seepage rate of the PVC lining. The normal rate of water use for this proposed condition shows a total demand of 118 acre feet of water for the year. Using the Golden State Water price of $2.23/CCF, The cost of water for this condition is $114,622 per year.

WATER BALANCE DATA

Proposed Condition: Using Lake Water for Irrigation, PVC Liner The water balance data for this condition uses the 2008 data from the previous tables. (See Figure 20) The PVC liner has a typical water loss of .011 inches per day. Using the lake as the source of the irrigation water will replace the lake water with the cleaner potable water from the water supply. As the lake water is replaced with the cleaner water, the lake water quality will be improved. The irrigation demand from the lake is 115 acre feet. At this rate, the lake will turnover every 136 days.The turnover rate for this option is higher than the recommended 90 days. Biofilters are recommended to increase the turnover rate to acceptable levels. The seepage rate for this table is the same as the previous table. (See Figure 20) Use of the lake water for irrigation together with replacing the soil lining with a PVC liner produced a net demand of 115 acre-feet. Using the Golden State Water price of $2.23/CCF, The cost of water for this condition is $111,710 per year.

WATER SUPPLY LINE / SHORELINE RECOMMENDATIONS / SKIMMERS AND RECIRCULATION

TRI CITY PARK MASTER PLAN

WATER SUPPLY LINE The highest demand using the month of July 2008 on Figure 19 is 19.1 Acre-feet. That is approximately 210,000 gallons per day. With a fill time of 7 hours, a flowrate of 500 gpm is required for the worst case condition. A draw down analysis with the irrigation flowrate and the potable water fill flowrate should be conducted to make sure that the lake level does not draw down more than 6 inches on any day. Any lake level drop of greater than 6 inches would be unacceptable aesthetically. SHORELINE RECOMMENDATIONS The shoreline currently in place is either settling in some areas or have fallen completely away (See Figure 22). Many areas have cracked. Reconstruction of the perimeter shoreline is recommended on the entire lake (See Figures 23 and 24). Currently the lake has a soil liner, pending further research and geotechnical report as previously discussed, the lining system can be selected.

FIGURE 22: Shoreline Damage

FIGURE 23: Original Shoreline

FIGURE 25: Skimmer Locations and Dead Spots

FIGURE 24: PVC Lined Shoreline

SKIMMERS AND RECIRCULATION Currently there are three skimmers at the lower lake as indicated by a red dot on Figure 25. During the preliminary inventory assessment the skimmers were noted to be of limited capacity and filled with debris rapidly. The configuration of the lake creates many â&#x20AC;&#x153;dead spotsâ&#x20AC;? (shown as cyan colored dots on Figure 25) where water does not circulate and debris collects. The skimmers are too few and not sufficient for keeping the lake clean. Increased frequency of debris removal is recommended in lieu of skimmers. The intake configuration of each skimmer location can be retrofitted and recirculation can continue at each current discharge point (yellow dot).

STREAM / WATERFALL UNDER THE BRIDGE

APPENDICES

STREAM One skimmer is currently supplying the stream located at the upper lake. The pump at the skimmer is sufficient to supply the flow at the stream. Our initial assessment of the stream indicates that the stream bed is leaking which is eroding the surrounding landscape and revealing the stream concrete lining (See Figure 26). PACE recommends a complete renovation of the stream and reconfiguring the stream with a more natural route (See Figure 27). WATERFALL UNDER THE BRIDGE Under each bridge at the island, waterfalls are recessed restricting the visual effect. Moving the waterfall further out from under the bridge and configuration of boulders and weirs will increase the visual effect. (See Figures 28 and 29)
