Executive SummaryIntertwined Design was invited by the San Luis Obispo Botanical Garden to develop a Conceptual Design for a new project inclusive of Visitor’s Center with classrooms and IMAX Theater, Botanical Gardens, and Amphitheater on a currently undeveloped site off Highway 1, north of the City of San Luis Obispo.
The objective of the project is to create a world-renowned center that provides educational, recreational, and conservational opportunities for the greater San Luis Obispo and Central Coast community.
Of specific focus is to present an environment that promotes an understanding and appreciation of the relationships between people and nature, and the importance of embracing sustainable practices in our lives. As such, a key design objective is to incorporate a wide variety of sustainable features in the facility’s design and construction.
The project as designed includes approximately 46,500 sq. ft. of buildings on a site of approximately 150 acres. Careful consideration has been given to the integration of the buildings and necessary improvements, such as roadways and parking, into the site such that there is a natural relationship between the two.
Given the very nature of a Botanical Garden, there are special connections between indoor areas and outdoor spaces. Highly flexible indoor spaces offer settings for display, education, and meetings. Outdoor spaces provide unique opportunities to experience the gardens themselves, as well as the many sustainable design features focusing on Central Coast issues, such as the living machine.
The IMAX Theater and amphitheater allow presentation of feature programs and the hosting of special community events.
This project represents a truly unique community vision, and opportunity.This Conceptual Design Report includes: site development and landscape plans, architectural plans, exterior and interior perspectives, structural design, suggested building materials and finishes, passive design strategies, mechanical system design, a review of sustainability features, project implementation schedule, and an opinion of the probable cost of construction.

Vision StatementsSan Luis Obispo Botanical Garden Vision
To create a world-renowned experience that provides educational, recreational, and conservational opportunities that promote an understanding and appreciation of the relationships between people and nature.
To deliver an unforgettable garden experience in which sustainable practices are an iconic, and innovative display that is integrated into an evolving educational tool.
Intertwined Design’s Project Approach
Intertwined Design’s Core Purpose is to Provide Exceptional Solutions within the Built Environment.
Our firm’s vision is to be “a leading provider of architectural, landscape design, engineering, and construction services on the Central Cost and throughout the Western United States – a firm that attracts coveted clients and highly talented staff.”
As a “full-service” Design-Build firm, Intertwined Design’s clients benefit from true integration of professionals in the planning, architectural, landscape architectural, engineering, and construction management fields. With all disciplines in-house, teamwork is truly enhanced, and every aspect of the interrelationship of design and construction practices a matter of our firm’s daily practices. This integration and idea exploration from the very inception of the project is all the more important with today’s focus on sustainability and green design. In simple terms, and as one example, our structural and MEP engineers do not just design systems as isolated responses to the architect’s design, but instead are key team members in the exploration of the very design solution itself. The full meaning of this total team approach is evidenced by the fact that even the firm’s structural engineers are LEED Accredited Professionals.
We believe that our proposed design response to the project presents a solution that offers truly exciting and flexible indoor and outdoor facilities, and experiences that promote an understanding and appreciation of the relationships between people and nature, the importance of sustainability, and the beauty and wonder of the gardens.
Intertwined Design appreciates this invitation by the San Luis Obispo Botanical Garden to share our vision.

Representative Projects
Environmental Nature Center
The Environmental Nature Center is the fi rst LEED Plati num Certi fi ed building in Orange County, California. The 9,000 sq. ft . interpreti ve center provides the Environmental Nature Center as a space to provide educati onal opportuniti es. The center responds eff ecti vely to harvest natural daylight as well as the cool ocean breezes. The use of natural venti lati on helps eliminate the need for air conditi oning of the building. The sustainable features include a photo voltaic roof, drought tolerant landscape with 15 nati ve plant communiti es, effi cient storm water management, as well as the use of composite wood products, and water effi cient fi xtures.
Through simple, cost eff ecti ve environmental design strategies, the Environmental Nature Center has become a living laboratory and educati onal tool for smart green design.
Baldwin Hills Scenic Overlook
Baldwin Hills’ program evolved through a series of public workshops with the local community (which initi ally requested that the park include ameniti es such as soccer fi elds and playgrounds before warming up to CSP’s sparer, more naturalisti c vision). Working closely with landscape architects Wallace Roberts & Todd (WRT) and California State Parks designers, Safdie Rabines began overhauling the site in 2006.
The buildings have been designed in accordance with the Hippocrati c oath: Above all, they do no harm to the landscape (or very litt le, anyway). Safdie Rabines’ master plan includes a visitor center, support building, and open-air pavilion, in additi on to a garden and a series of trails.
The Warren Skaaren Environmental Learning Center
Sensiti ve to the environment, this educati onal center uses nature to teach the public about nature and how to use nature to facilitate the building. Its three cisterns collect the water that falls onto the building and uses it throughout the site to help keep it sustainable and self suffi cient. Conserving energy and resources is one of the main goals for this center along with educati on. Photo voltaic panels provide a great amount of energy for the functi on of this building and the use of recycled cellulose insulati on, local stone and other sustainable materials enhance the green nature of this building. The educati onal aspect of this center moves the architecture to be focused on the outside which is the reason for 12 foot overhangs that host outdoor classroom spaces.

Redding Residence at Desert Mountain
Sitting at home in this area is so blissful because of the optimal views and comforts that it provides for the owners. The rammed earth walls create thermal comfort at night and the long overhangs provide shade in the day when the sun beats down to heat this dry and arid area. Outdoor living is promoted in this space and it can’t be avoided because of all the glass that surrounds the building. Despite the exposure of glass, the design keeps it very private and cozy.
In addition to the spectacular views, the relationship to the surroundings besides views are extremely important and well integrated into this building because of the use of the site earth creating the rammed earth wall themed in the building.
Tejon Ranch
From design, to construction, to the finished community, every aspect of a Tejon Ranch development demonstrates respect for the land and the environment guided by the Ranch’s historic core values of conservation and good stewardship.
A small portion of the ranch is occupied by Tejon Mountain village which is a remarkable, environmentally sensitive mountain resort community of housing, world class resort hotels, championship golf courses, hiking and equestrian trails. The community embraces smart growth development by including centralized amenities, de-emphasis of the automobile and replaces it with mass transit options and an encouragement for walking and biking. The community includes an industrial complex providing local employment opportunities and new economic development for Kern County
The Chino Creek Wetlands and Educational Park
The Chino Creek projects primary focus is on community education concerning the value of conservation and the environmental importance of wetlands. It is an advocate and demonstrator of improving the hydrlogic system for water supply, storm water treatment, and water efficiency. The 22 acres is landscaped with native species and is irrigated with a state of the art water management system. We carefully constructed an educational experience using trails, sampling stations, picnic areas, a visitor’s center, parking, bridges and an amphitheatre within the riparian and wetland habitats.

Michael Stone has always had a passion for the built environment and the emotional connection people have with spaces they use. This has led to a career path covering both residential and commercial construction. Michael is one of the founders of Intertwined Design, bringing together a diverse group of individuals within the industry with the goal of strengthen a project’s outcome. As one of the most successful and prominent people within the company, Michael has been responsible for designing some of our most complex and unique projects. He has brought a reputation to the company as a person who understands the ultimate goals of the project and works in collaboration with the client to create the best possible design, delivering innovative but pragmatic design solutions.
In past projects, such as the Capitol Hill Library, Michael provided a quiet refuge space while holding its own in a lively architectural environment. To promote life, the brick portions of the building were wrapped in steal mesh, providing a space for 16 varieties of climbing plants. Lighting was placed between the brick and mesh to create a green glow after the plantings matured. In his design of the Spring Creek Ranch Golf House, he reacted to the opportunities and limitations of the land while satisfying the owner’s very detailed program. A division into three wings defined the different functions within the golf house, and provided the members with a comfortable space oriented to the views.

Gabriel Llamas has worked on a number of important projects throughout his career. He started out at EHDD Architecture and immediately began work on the Monterey Bay Aquarium. Working on this project he contributed and learned a lot about a large educational center that had been successful for over 20 years. Gabriel became the Project Manager on the last project he worked on at EHDD, the San Mateo Public Library. This building incorporates state of the art technology into many educational tools within the library. On this project Gabriel became more familiar with sustainability and LEED criteria. Shortly after, Gabriel assisted Renzo Piano with his design of the Academy of Sciences, which achieved a LEED Platinum rating. This also is a highly educational and sustainable building. The most recent project Gabriel has worked on was The Cathedral of Christ the Light. This is a very striking building with great natural light and also a very beautiful aura when it glows at night.
The experience Gabriel has accumulated through his work on these projects makes him an ideal designer and consultant for the Botanic Garden in San Luis Obispo. He understands what it is the clients are striving to achieve and his involvement in so many successful past projects proves he will be able to make this garden flourish and thrive for many years.

Basis of Design There are four areas of primary focus that the Intertwined Design Team identified in developing the design approach to this project. These areas of focus are:
Sustainability
San Luis Obispo Botanical Garden promotes an environment were individuals and groups can grow in their understanding and appreciation of the relationships between people and nature, and the importance of embracing sustainable practices in our lives. The Design Team worked to incorporate a wide variety of sustainable features in the facility’s design and construction. These include: rainwater capture; water re-use (through the living machine); power generation through PV solar panels; solar water heating through flexible polymer panels for domestic hot water and space heating; natural ventilation; shading features; and importantly, the materials chosen for construction of the buildings and site improvements, including local materials, and rammed earth walls.
Quality of Experience
The quality of each individual’s experience while visiting the Botanical Gardens is of primary importance. It is the goal for everyone to depart with new understanding of not only the relationship between people and nature, but new ideas on how they can personally improve that relationship through knowledge and through the making of sustainable decisions. The quality of one’s experience is to be more than just enjoyment of the garden and beautiful architecture, but the fun of learning that will await them around every corner and every visit.
Relationship to the Site
This is a wonderful site. It is convenient, yet remote, with a beauty all its own. In developing the site, it was the Design Team’s ongoing mission to integrate the buildings and site improvements into the natural contours of the site as much as possible. This approach is sustainable, of course, but it also creates an environment where man’s building and nature co-exist comfortably and naturally.
Flexibility
The Visitor Center will serve a variety of purposes, presenting and hosting exhibits, educational programs, presentations, meetings, etc. As designed, the Visitor Center well accommodates these many and varied functions. Spaces are designed to be flexible, dividable, and adaptable. Each space is carefully linked to the other.

LIVING MACHINE. Allows for water reuse and provides an educational experience.
SERVICE ROAD to the Service Yard and also doubles as an EXIT for AMPHITHEATRE VEHICLES after a show.
RESOTRED WETLANDS to help filter contaminated water from HWY 1 and the project back into the water table.
The VISITOR’S CENTER is oriented on the East/West axis to maximize the sun exposure.
TERRACED PARKING provides parking for about 700 cars on grade.
We have a BRIDGE that will step over the riparian corridor that will enhance the entrance experience and excite the visitors arriving.
Highway 1 between Morro Bay and San Luis Obispo.
The ENTRY PLAZA for the AMPHITHEATRE is a space for people to find venues and places to investigate before, during, or after performances.
We are proposing that this area possibly be free to the public
The TRUCK/BUS ENTRY road allows vehicles to go up to the amphitheatre. Also serves as an EXIT ROAD for mass pedestrians after concerts
The TURN AROUND allows buses to drop off and pick up people and is part of the GRAND ENTRANCE to the building.
The PARKING STRUCTURE is a 2 LEVEL structure that holds about 850 cars. The second level steps back to reduce cutting into the hill.
The idea for the entrance of the garden is to have a STOP LIGHT to slow traffic to the garden and help maintain traffic leaving the garden.

Entering the site, we’re proposing a STOP LIGHT on the South side of the site off of Highway 1.
Goals for putting in a Stop Light:Slow traffic to intrigue people and peak • their interest in the Botanical garden.Allow for people to turn left onto • Highway 1 going back to San Luis Obispo.After large events the traffic flow will be • substantial and the use of a stop light will help to alleviate the traffic from within the site.
Entrance to the Botanical Gardens
Entering the site we are proposing a stop light that will slow traffic and peak their interest about the Botanical Garden. It will also allow people to turn easy without worry about traffic passing by at high speeds. The experience of enter the site is what excites the visitor. We are creating a warm feeling that will welcome them into the beautiful surrounds of nature. The plants around the road will be San Luis Obispo native plants to feature that we are in the Mediterranean climate. The trees lining the sides of the road will make a nice frame for entering the site. The bridge over the ripparian corridor will be open to the sky and the moutain scenery can be viewed from there. Showing the way to parking will be easy with separating them to either the left or right. Continuing onto the turn around in front of the Visitor’s Center is another part of our Grand Entrance that is ICONIC for our design. Buses and trucks will turn around to drop off their loads for the Visitor’s Center. Once the patron is parked or dropped off, they can proceed to the entrance of the building and start their glorious and unforgettable experience at the Botanical Garden.

Site Development
The AMPHITHEATRE PLAZA is large enough to the trucks to turn around in and for audience members to load into during the beginning, intermission or end of a concert.
LIVING MACHINE. Allows for water reuse and provides an educational experience.
A TICKET COLLECTING STATION for visitor’s going into the garden.
Ramp getting to the ENTRANCE TO THE GARDEN for ADA accessibility
The VISITOR’S CENTER is separated into three levels. The office level, the main level, and the loft area.
Minimizing asphalt used and creating a natural alternative, PERMEABLE PAVERS with grass growing around them will be used.
The building ENTRANCE introduces the rammed earth wall that connects the outside to the inside and then through the building to the outside again to the courtyard.
A TICKET COLLECTING STATION will deal with security for both the amphitheater and the garden. The patron will be directed through a certain ticket station according to what type of of ticket they have.
This part of the garden is the proposed CORRIDOR TO AMPHITHEATER sculptural art will be showcased along with future performers.
The COURTYARD to the garden is open for many activities and creates a wonderful outdoor space. A DONOR GARDEN allows for gratification in a beautiful integrated way.
The MULTI-USE spaces will be 5’ above the ground floor to help separate its use from the visitor’s center.
TRUCK and BUS ENTRANCE is key to being able to get the equipment and people up to the amphitheater easily. The road doubles as a way to exit mass amounts of people from the amphitheater
The RAMP system from the parking garage to the building is designed to create an ICONIC EXPERIENCE.
The parking garage is STEPPED BACK to minimize cut and fill also creating a clearance area for BUSES and TRUCKS to travel through.

Parking
Terraced parking is provided on four terraced on grade levels to minimize cutting into the site. The upper level is the same elevation as courtyard and entrance to the Visitor’s Center. ADA parking is provided at this level. This level is striped with 78 spaces. The lower levels are close to the employee entrance at a 15 foot elevation difference from the main entrance level. These levels are unstrapped, providing flexibility for valet parking at major events.
Landscape planters are provided throughout the parking to break up the feel of the larger paved surfaces and offer are more natural feel. A row of trees line the edge of each parking level and continued out into the hillside to intertwine site landscaping with the landscaping buffering the parking. Unlike the parking structure, the terraced parking cannot be seen from Highway 1. Parking lot light poles are equipped with banner attachments to advertise events and provide festive color. This lot accommodates approximately 700 vehicles.

Landscape DesignInspiration for the San Luis Obispo Botanical Garden Courtyard derives from the traditional Italian villa garden style. San Luis Obispo shares the same dry, mild, warm climate that the Mediterranean basin posses. Both regions boast rolling –golden hills, gorgeous coasts, and acres of wine grapes. A stranger could easily confuse pictures of San Luis Obispo County with the Italian coasts.
While the two regions share beautiful qualities, the San Luis Obispo Botanical Garden Courtyard is adorned with Mediterranean plants found through out San Luis Obispo County. Beautiful yellows, oranges, pinks, and lavenders will help decorate the courtyard and easily represent the San Luis Obispo landscape to patrons.
The first level of the courtyard features sandstone pavers on a drought tolerant lawn. The lawn not only provides a beautiful alternative to pavement, but allows water runoff to be reduced. Trees found throughout the county will help to shade the courtyard and enhance the San Luis Obispo experience. Planter boxes will display the native plants and seat walls juxtaposed of planters provided places for patrons to relax and enjoy the views of the gardens.
Descending from the first level, a smaller terrace is available for private use. Patrons can have garden parties, weddings, or any other private event. The terrace has terrific views of the garden, along with the beautiful rolling hills.
The second level is entirely paved. Large unpaved spaces are filled with a variety of plants ranging from flowers, shrubs, and grasses. The planters are arranged so that patrons can casually stroll and weave between planters and admire the flora of the region.
Once to the third level, patrons can enjoy the shade provided by a large-scale pergola. Under the pergola more plants are available for viewing. Along with plants, a ground level reflection pond lies underneath the pergola. The reflection pool is reminiscent of classic European villa design and creates a cooling effect. From the third level, patrons are directed to the main entrance to the botanical gardens and are free to go as they please.

The San Luis Obispo Botanic Visitor’s Center creates an iconic experience that focuses the visitor’s attention to the beautiful artistic and educational opportunities in the garden.
The objective of this building is to really focus on the garden to the North. While there are views to the South, of the mountain ranges that are featured, the main focus is out toward the garden which the patron has come to visit. Because the building’s location on the site slopes toward the West side of the building, the design adapts to that and creates a natural separation of spaces for the occupants. The office level steps below the main level of the building and allows the visitors to enjoy their experience without seeing the mass amount of staff that help operate the facility.
The building’s goal is to combine and integrate the garden experience that it is focusing on into the building itself. Bringing the outside to the inside nicely allows you to feel like you’re already in the garden experience. The lobby space has a large planter box that allows the plant and natural life to join the occupants inside the building.
There are many beautiful spaces in this building which will host the many events in the future. Weddings, conferences, dinners, movies events, dances, etc. The goal is to allow any visitor to enjoy and experience an amazing garden and space. ADA accessible ramps allow for people get from one place to another and still make it a beautiful enjoyable path.
Roof gardens around the building allow for a natural and exciting place to be but it also is part of the many sustainable strategies that that incorporated into the building. Rammed earth wall is used aesthetically but also to utilize the earth that will be moved and manipulated around on the site. The mass of the wall allows heat to be collected in the day and then to radiate the heat at night. Ventilation is solved by created a high ceiling and loft space to carry the heat up and out through the high windows. Light in the spaces is abundant which is controlled by the building’s wooden slates that shade the inside.

Structural Steel HSS Tubing Mo-Utilizes longest and furthest apart solid walls already in the architectural plan to resist earthquake and wind forces. Cement proportion is reduced by replacing 15% - 25% with Fly Ash Class F. Fly ash; a by-product of the combustion of coal. It improves workability and finish-ability. Exposing these high thermal masses such as the concrete and rammed earth elements to the occupants allows for thermal heat gain and radiant heat during certain times of the day.
Allows for larger openings in the wall for bay window placement to enhance the views we are trying to achieve, while resisting the earthquake and wind forces. Minimizing the use of these frames is critical to keep cost down. Structural steel manufacturers are able to produce up to 97.5 % recycled material. Ability to be prefabricated and taken to the site reduces construction time and allows for better precisian.

Building MaterialsThe focus for the building is towards the garden and its many natural beauties. In keeping with the design premise of incorporating the build into the site, the building utilizes natural materials for both functional and aesthetical purposes.
Rammed EarthRammed earth walls are used to integrate the building with the site. These walls create a beautifully textured surface as the earth becomes part of the building both structurally and visually. This natural material creates a unique transition experience for the visitor as they enter the building. A main rammed earth wall draws a visitor through the building, providing a visual comfort as they travel from the Entry Plaza through the Visitor Center and onto the Garden Courtyard.
GlassWith the Visitor Center oriented to focus on the Gardens, the spaces within the building are designed to provide natural light to spaces and exterior views. The large amount of glass serves as a transparent link between interior spaces and exterior garden spaces. This blurring of the lines between the built environment and its natural surroundings allows the Visitor Center to intertwine the typically distinct boundary between indoor and outdoor. The use of glass allows for the visual extensions of spaces to the adjacent exterior spaces giving the spaces a larger feel.
MetalsSteel is used as structural support in some areas to allow for the expanses of glass. The design utilizes these structural elements as architectural expressions of form through out the Visitor Center and Multi-use space
Brushed Copper is used as trim around the edges of the roofs over the lobby space. This gives the building an iconic roofline roof which appears to be floating over the building but still a base for roof gardens above. The use of copper allows the roofline to represent technology and nature in the refinement of natural materials.
Metal roofs are used on sections of the Visitor Center as a material that can easily transport water of the roof for rain water collection.
ConcreteA flexible material that can be used differently in different areas of the building.
The outside patios are made up of concrete and stone that is permeable so that the ground can be part of the landscape and less harsh to the visitor. Concrete walls are used as a material to work in unison with the rammed earth walls. Concrete has the ability to be colored and textured to meet the desired appearance.
Finished concrete floors allow for a durable surface that can be easily maintained while still providing the ability to be used in formal atmosphere. Concrete floors also provide the ability to create different patterns to enhance the experience.
WoodThe front of the retail space is partial covered wood slats to help shade the building while also giving the building texture and differentiating functions of the building from other parts. The use of a natural material on the entry façade accents the use of the rammed earth wall and the buildings use of sustainable materials.
Over the entry space are exposed timber trusses, bringing the comfort of natural material into the structural components of building. The wood trusses are located in the Lobby area and create a warm and open feeling for the large space.

Passive Design Strategies

Ventilation
Ventilation
The Building Orientation is primarily on in East-West axis to utilize the maxim solar exposure for solar panels, winter solar heat gain, and natural ventilation.
Thermal Mass is used in the form of rammed earth and concrete floors to maintain a consistent temperature in the building through out the day.
Natural Ventilation can be used due to the buildings orientation. Ventilation is used to help maintain a consistent temperature level with the building. It can be used in two forms: cross ventilation and stacked ventilation. Taken advantage of the building height of the IMAX the loft space can act as form of stacked ventilation for the lobby area, while cross ventilation is used through out other portions of the Visitor Center.
Solar Heating is utilized during the winter months by allowing the winter sun to enter into the main space. Solar energy is also used to heat water which is used in to heat the space through a radian floor system.
Summer Sun is minimized from entering the building through the use of overhangs blocking the sun during the warmest times of the year.

Conceptual Mechanical Design
Although the building primarily utilizes passive strategies for heating and cooling, a mechanical system has been incorporated when passive systems cannot meet the comfort requirements of the space.
Cooling the BuildingTo maintain the buildings concern for the environment, the system was designed to efficient in it energy use and. Air handlers are placed on the roof and are connected to an air chiller and thermal energy storage on the ground. The chiller and energy storage units are place off the service road behind the multi-use spaces for maintenance access and the proximity to other site utilities.
By using thermal energy storage, IceStor, for cooling proposes, the building is able to dramatically reduce energy costs, the most advanced cool storage system ever designed. IceStor static glycol tanks produce and store ice at night, when energy costs are lowest, and discharge cooling during the high on-peak rate period. By shifting this portion of the air conditioning electric load to off-peak hours, IceStor reduces demand charges and lowers peak power usage.
Radiant Floor HeatingThermal energy storage can also be use for hot water, which was heated by the sun or boiler, to be used in the radiant floor heating. In order to accomplish radiant floor heating, the pipes from the solar hot water will be laid into the floor. Using this system will save on energy costs up to 40%. Warm up time is very fast as well and installation times are quick, saving on construction costs. Having heating from the floor creates a more natural feeling of warmth, providing a more comfortable experience for patrons.

Sustainability FeaturesLiving MachineThe Living Machine mimics nature because it is a natural water restoration system instead of an artificial water treatment plant. It’s innovative aquatic treatment system restores waste water to near-drinkable quality using native, nutrient-absorbing wetland plants and animals. The water that passes through the system is typically more pure than water that comes from municipal water treatment plants.
Solar Hot WaterSolar Hot Water technology is the cleanest, safest and quietest source of energy. The panels used are made of durable, lightweight, ultraviolet-resistant, polyolefin material. It is over 5 times more efficient at capturing the sun’s energy and converting it into usable power than photovoltaic systems. This source of energy also does not produce any greenhouse emissions. The operational costs are low, because it’s energy is derived directly from the sun and the maintenance costs are very minimal as well. Using Solar Hot Water will dramatically reduce energy bills, saving over 50%in hot water heating costs.
Day LightingWe have carefully installed window to displace most electric lighting. We focused on specific programs and functions of the building to designed the building to allow daylight to enter the building where most needed. The floor plan is generally an open design so that light will penetrate as far as possible. Glazing is installed in most directions, but really concentrated on the northern faces to maximize an even, indirect light. Even though some spaces are built into the land, underground, lighting is still able to be incorporated in these spaces through skylights, and even some windows placed on the northern face.
Thermal Mass For thermal mass rammed earth is used extensively throughout the building. The rammed earth walls will help to control the humidity of the internal spaces in the building as well as stabilize interior temperatures. The density and thickness creates a slow rate of thermal conductivity for cold temperature penetration, which is important for the cold winter nights here in San Luis Obispo. There are also many extremely hot days experienced during the summer, when the garden will be visited most often. Fortunately, it takes almost 12 hours for warmth to work its way through a thick rammed earth wall, which will keep the patrons inside the visitor’s center cool and comfortable. Rammed earth is also very sustainable, using local materials, often very inexpensive or free and it reduces the need for lumber, creating a very minimal environmental impact.
Photovoltaic PanelsPV panels are some of the most popular forms of energy, and of course are incorporated in this building. Panels are installed on the roof of the IMAX, because it is such a large space, so it allows several panels to be placed in this area. Photovoltaic panels will also be on the roof of the locker rooms, which are, like the IMAX roof, oriented to the south to maximize solar exposure. With panels on such a high roof of the IMAX, it will be very difficult to see, so the visibility of panels is low, unless on the higher part of the terrain. Installation of photovoltaic panels will tremendously reduce energy costs of the building over time.
Rain Water CollectionWith so much land and plants, water is a very valuable source, and the opportunity to save it cannot be wasted. Such a large footprint of the building actually works to our advantage here. This increases our roof area to collect rain water. Water will be collected by the gutters on the roof and transported to a cistern or tank for storage. Several cisterns will be incorporated on site to save as much water as possible.

Risk Mitigation
Potential Risks
CEQAGetting approval from CEQA is a tedious and time consuming process that can delay parts of the project. The procedures and requirements are substantial because of The Environmental Bill of Rights and approving that the building is not a significant environmental impact.
WaterThe use of water for this site is going to be a large amount, an amount that can not rely on water shed from the site. There is no well to access water for this area so the water must accessed from somewhere else which will be very expensive.
Fundrai singTo building this facility we have estimated that it will cost approximately 51 million dollars. Beginning the garden was supported by the San Luis County Parks Department and will possibly get some funding from the city but a majority of the money will have to be raised from donors, benefits, etc.
Price EscalationDepending on the economy, the price ranges can fluctuate significantly making prices go way up in the worst case and way down in the best case. We have to prepare for the worst case, in moderation, so we assume a 2-3% increase over the period of the project.
Soil ErosionExposed soils could create land slide situations that are difficult to work with. The clay soil expands and contracts so much depending on the moisture on site which creates opportunities for the building to shift or move.

Risk Mitigation
Risk Mitigation for CEQA Approval
To be successful in earning approval, we plan to abide by all of the rules and regulations of CEQA. With our recent past project, the Warren Skaaren Environmental Learning Center, we have dealt with the process of CEQA approval and we have developed many connections to the people who are part of the process. We all have learned and specialized in know about the environmental impacts of the buildings and landscaping we design so the knowledge of these rules and regulations are always at the forefront of out ideas and tasks. We plan to be tedious and responsible with our design along with checking in with the people who will be approving the building in order to keep everything on schedule and done correctly.
Risk Mitigation for Funding
With funding, we are very keen in what needs to be done in order to raise the kind of money that is needed to build this facility. Being involved through the process is key to getting people excited about these opportunities. Any sort of event or fundraiser that is planned we will make sure we are involved to educate the people about the possibilities of this facility. Money will always be hard to raise but ensuring that the cost is as low as possible with the quality still being high is something that we have made sure of. We have designed the building and facilities around in a way that is easily phased, which allows the client to building things smoothly when the money is available to be used to build.
Risk Mitigation for Potable Water
Our biggest challenge is water usage in the building and on site because amount on the site will not be enough. One strategy will be to collect as much water as possible on our buildings and on site to filter and store on site. The way we are filter water is naturally through the wetlands that are going to be kept in tact at the South West side of the site next to the baseball fields. This will allow us to cut down on costs by not having to have a man-made filtration system for all of that water. Our goal is to capture, filter, use, filter and reuse water that is being used throughout the site and building. This alone cannot solve the water shortage that will occur. We are recommending and are strongly going to encourage the construction of the water system that San Luis Obispo County is trying to establish. This distribution infrastructure will get water resources to the coastal regions of the central coast which we can use and be part of as a resource for our water. Our efforts will go towards getting this system built and also encouraging other adjacent facilities such as Cuesta College to support this system as well. Getting more organizations and places involved will help to achieve the ultimate goal of this system getting built.

Constructability
Construction and Constructability Choices
This project is significant in size but what makes our design iconic, sustainable and construction savvy is our ability to create something that integrates all of these things together beautifully with a focus in mind. A focus of the Botanical Garden. We have made sure that the Mediterranean climate is featured and kept in mind for what will be constructed.
Designing this building to be phased easily was a big task but it was one of our ultimate goals because phasing this building is very important to the success and future of the garden facility. Keeping everything simple but clearly integrated with each other will help to allow for construction to be done while facilities already built can be occupied. The expanding preview garden will continue to bring visitors to the site and will generate finances to construction.
The parking situation is difficult because the amount of cars needed to get onto the site was significant. In order to solve this problem we split up the parking into two different structures, the Terraced Parking and the Parking Garage. Only one would be constructed simultaneously with the Visitor’s Center because the amount of people visiting the garden will not be a significant amount. The garden will only just be starting to mature and come into its own so numbers that will be generated to see the garden might be a little lower than when it is fully matured. Once this happens the second parking structure can go in. The phasing of these three structures will most likely be because of the financial ability to build them. Only a few structures will be able to be built because of this.
The Amphitheater will be a large construction project that was not in our scope but the corridor going up the the amphitheater will be constructed in the proceeding future after the amphitheater is built. This will allow people to access and use this facility and it can help to generate money as well. The amphitheater is going to be a huge draw to the garden area and so the sooner the access to this facility is done, the sooner it can be available to be used.
A large part of the costs for this project will be in cut and fill because of the parking garage that is built into the hill and the IMAX theatre which is 3 stories below ground. Doing this allows the parking garage and the IMAX theatre to seem insignificant in comparison to its real impact on the site. The goal, again, is to keep the focus on the garden and keeping these large, massive structures as hidden as possible is necessary for the experience to be about the garden.
