A Recipe for Disaster:
addressing Californiaʼs wildfire environment through fire ecology and design. Redding, California LA 461: Senior Studio - Spring 2020 - Winter 2021 Faculty Advisor : Cesar Torres
My senior research project deals with wildfire risk management, protection, and response in the wildland urban interface (WUI). With wildfire activity increasing throughout the West, WUI communities must increase mitigation measures and be prepared for when wildfires ignite. The project suggests five mitigation techniques to be implemented on the project site to reduce the risk of structure ignition, increase wildfire response time, and keep community members safe. Strategies are applicable across all WUI communities. 1
Wildfire in Redding The site is located along the western edge of Redding, CA in Shasta County along Highway 99. The site sits next to the Sunset Heights neighborhood overlooking the Sacramento River. The site is currently a planned subdivision – Salt Creek Flats. The site burned over in the 2018 Carr Fire and several newly constructed homes within the subdivision burned over. Currently reconstruction and new construction is taking place.
Whoʼs at Risk? 13,437 residents in Redding are exposed to wildfire risk.
Shasta County Northern California
4,884 residential structures valued at 686.5 million are at risk.
Fuel Types of Redding
Within the city, many residents are exposed to wildfire risk due to California’s climate and the surrounding vegetation. Wildfire is common in most of California. Redding is at risk for wildfire. There have been numerous large and small scale fires in the area over the decades.

High Traffic Areas
High traffic areas are centered around Downtown Redding. It is a congested area because the highways are used as main paths of travel.
High Fire Severity Risk Area
13,437 residents are exposed to wildfire risk. Mostly along the west side of Redding where houses are part of the urban wildland interface. Vegetation consists of chaparral, pine and oak communities - all subject to burn on a regular return interval.
High Flood Potential Area
548 residents are exposed to potential flooding. All of the exposed residents live along the Sacramento River. Shasta Dam is located north of Redding along the Sacramento River and has the potential to fail and flood parts of Redding.

education
Communities in the wildland urban interface need to take actions to mitigate risk and improve resiliency. Building resiliency means employing strategies to make your community safer. 6
Community education is achieved by making fuel management visible and disseminating information on fire mitigation and fire ecology. Local capacity is increased by providing dual use park infrastructure that can be utilized as an incident command base during fires. Local capacity also involves identifying existing infrastructure that can be used in incident response.

Site Mitigation Zones
fire road
Site mitigation zones protect the neighborhood East of the site from wildfire. The wildfire threat is to the West and would likely be driven down towards the homes from the wind and topography. Zone 1 is the most protected, while Zone 3 & 4 make up the first line of defense.
Buenaventura Trail
Zone 1
disc golf course
This urban zone is the most protected - with vegetation that has high fuel moisture and low fuel continuity.
Zone 2 This zone has native vegetation, but program use keeps fuel continuity low with little maintenance.

Zone 3
comm. center
The fire road creates a 200’ wide fuel break through the park. This is meant to slow the spread of fire and compensate for smaller fuel breaks in Zone 4.
Zone 4 Fuel breaks between 50’100’ are maintained along the hiking trails. These act as the first line of defense against fire spreading East towards the city.

Designing to Increase Local Capacity
Dual Use Infrastructure: ICB Takeover The project is designed for normal use and incident response use. The gymnasium holds sports practice and recreation classes during normal operation. When incident response is needed in the surrounding region the gymnasium transforms into an Incident Command Post for a Type 2 Incident. On the left, gym-goers come and go for the regularly scheduled classes. On the right, the site is being used for incident response and senior firefighters gather for a briefing on the latest Incident Action Plan.
The gymnasium is equipped with electrical hookups, running water and indoor office space that is needed to house an Incident Command Post.
Temporary facilities like portapotties and a medical tent are brought in to meet demands of the increased site use.
Firefighters gather for a briefing on the latest fire activity and updates to the Incident Action Plan – the large gathering area in front of the gymnasium allows for a crowd to form.
Regular site use – people arrive to use the gymnasium. 13
Existing Spaces Suitable for Incident Response
An incident command base or “fire camp” is needed to respond to large fires. The area is used for staging, logistics, and planning and requires adequate amounts of space (between 9 - 46 acres). In addition to the project site, there are other existing spaces in Redding that can be utilized for incident response. Areas over 9 acres were selected to be integrated into the local capacity strategy to serve as “spill-over”.

LA 406: Interdisciplinary Studio - Winter 2020 Project Contributers: Nirmala Navarro - LArch Ashely Fernando - Arch Ryan Huddleston - Arch Josh Brouwer - ArchE Austin Zhu - ArchE
Our project group designed an archive for Floyd Norman - the Santa Barbara native and Disney animator. The archive is designed to convey the principles and methods he applied to his art and life. In animation, the artist starts with straight grid lines, penciling in rough shapes, and smoothing out edges to create a continuous and formulated drawing. Our group replicated this process - using it to structure the building and site. The site is structured by a grid, with curvilinear lines used in the landscape and building. 17

Cal Poly Campus Rain Garden Cal Poly San Luis Obispo, CA
Student Leadership in Green Infrastructure - grant funded project - Fall 2019 - Fall 2020 Project Contributers: Jena Beck - Horticulture Michael Lozano - LArch Tobin Hook - LArch Ellen Burke - Faculty
Over the course of a year, the SLGI group worked to design, permit, fund, and build a rain garden on our university’s campus. The project tackled a runoff-prone area and turned it into a functional and beautiful garden that provides habitat for pollinator species on campus. The garden’s concept is derived from the orange orchards on our campus, with the garden taking on a similar row planting scheme. The basin form is irregular and curvilinear to contrast with the linear planting scheme. 27

To connect (per California Phase II LID Sizing Tool) the two areas, the planting was extended to provide interest in Capture volume = 125 CF front of the portable and draw (approximately 6” deep over 250 sf; total rain attention to the partially hidden garden site = 550 sf) portion.
The basin site collects water runoff from the uphill mulch area. A curb cut was proposed to facilities to collect runoff from the paved area. We extended rocks up to the curb in case facilities makes the cut in the future.
The garden is best seen from the parking area above the much. Water runs down from the mulch area and into the retention basin. Most people move by the site quickly on their way to class so the design must be legible to these viewers and crop rows are noticeable even when driving. 28

From the shade study of the site, we found that the site receives a lot of shade throughout most of the year. This helped us to pick appropriate plants for the micro-climate. Our plant list was then approved by the facilities department.
Planting Selections
Carex praegracilis ‘Chisai’
Carex flacca ‘Blue Zinger’
Carex grasses are used for the crop rows. They have low water requirements but can tolerate standing water during rain events. Two species of varying color were used to provide distinction between the rows.
After installing the carex species on site, we found that the deer on campus prefer the ‘Blue Zinger’ variety over ‘Chisai’. Unfortunately they have not been growing in at the same speed.
Calamagrostis x acutiflora ‘Karl Foerster’
Salvia leucantha ‘White Mischief’
Achillea x lewisii ‘King Edward’
Calamagrostis is a full sun grass that can get up to 5’ tall. It is used in the back corner of the site to screen the sharp triangle shape of the back of the site.
Sage is used as a pollinator species and adds some color to the garden. It is also used as our large shrub to buffer the base of the portable and act as a backdrop for the rows of carex.
The yarrow is used for a pop of color on the ground. It is dispersed throughout the planting rows. Yarrow is also a native pollinator species, attracting many insects to the site.
The plants shown here are the plants ordered and installed on site. These plants differ slightly from the original planting list as we were limited by what the nursery had in stock at the time. Despite the changes to the plant list, the overall concept is maintained and many pollinator and native species were still installed.
30
Prior to site excavation, we flagged out the retention basin shape for the mini excavator operator to follow. The basin was excavated deeper than needed, then partially refilled to amend the soil.
After basin excavation, the project team and student volunteers filled the basin with compost and rocks to ensure healthy plants and good drainage.
Plants were ordered and delivered to site ahead of installation. Before student volunteers arrived, I placed each plant to ensure they would be installed according to the site plan.
Student volunteers from the department’s planting design class helped us install the plants and drip irrigation system.
After plants were installed, the area was mulched and cleaned up. Image is taken a few weekends after plant installation. We are still waiting for the plants to fill in and mature.
During January, San Luis Obispo experienced a 25 year rainfall event. The basin was able to retain the majority of the excess storm water from the mulch area.

Internship with BCRA - Summer 2019
During my internship with BRCA I assisted with the generation of construction documentation, renderings, presentation materials, and planting designs on multiple projects. The following is a sample of the work completed over the summer. Samples are taken from the Yelm Middle School replacement project and Gamut housing development project in the Seattle area.

(above - top) dead fall logs were collected and strategically placed to prevent hikers and bikers from cutting switchbacks and further disturbing the surrounding areas. (above) a bridge was constructed through a marshy area on a new mountain bike trail to prevent the trail from rutting out during periods of rainfall.
36
(above - right) a turnpike was constructed at the edge of a swamp to prevent trail erosion and help with water runoff. First a trench is dug then filled with rocks and crushed down. Soil is placed on top to create a smooth surface for bikes. Placing rocks below the trail surface means less water will sit on the trail. The trail is crowned to help with runoff as well.

Trail Crew Member with Rocky Mountain Youth Corps - Summer 2020
Over the course of the summer, I worked with 9 others on a trail crew, building and maintaining recreation trails for hikers and bikers in the Arapaho and White River National Forests. In partnership with the Dillon Ranger District, our crew worked to build new trails and construct features such as bridges and culverts to help increase the maintenance lifespan of the trails.
