Abstract[edit]

Stephanie Calderon and Michael Wold created a landscape design of the front area of the Jefferson Community Center and Charter school. The landscape included edible plants, xeriscape elements, and site specific soil assessment and solar requirement. This project was created to address food security and the access of it for low income and culturally diverse neighborhoods.

Background[edit]

The Jefferson Projectis a symbol of community revitalization through physical efforts of restoration and social action towards a safe and accessible community space. This project is created under the guidance of Heidi Benzonelli, Lonny Grafman, and Humboldt State University's Engineering 305 course (Spring 2013).

The Westside neighborhood is home to an estimated 3,800 residents with approximately 850 children. According to the Westside Community Improvement Association (WCIA), the Westside neighborhood is the most densely populated neighborhood in Eureka. The Jefferson Community Center and Charter School (JPCC), caters to the most ethnically diverse and low-income neighborhood in Eureka California.

The Westside Community Improvement Association (WCIA) formed in 2007 with intents on purchasing the vacant lot of the Jefferson School. WCIA has been awarded several planning and scoping grants from local agencies such as PG&E and the Calfresh Program.

In 2011, the WCIA was granted a California state community revitalization grant to create a park and restore the building to run as a community center and charter school. Plans for revitalization and renovation of the 70 year old school buildings began by removing black top areas and replacing them with playgrounds in order decrease urban blight and to increase open space for community interaction. This is just the beginning of the revitalization of this community space.

Project Description[edit]

LandscapeJeff.jpg

The objective of this project is to transform the landscape located at the front entrance of the Jefferson Community Center and Charter School. The landscape will be converted from traditional European style landscaping into a functional, aesthetically pleasing, edible landscape, consisting of various fruit trees, nut trees, berry bushes and herbs. The landscape will serve as safe access to organically grown foods for the greater Westside neighborhood residents and Jefferson Charter School students.

The chosen site was surveyed for sun exposure, and pH of soil. In addition, water usage of plants will be considered as a theme in the overall design. The final design of the edible landscape will incorporate the economic capacity of the organization, access to community donations, and community support through workdays.

Literature Review[edit]

This is a review of the available literature pertinent to the comprehensive edible landscape project at Jefferson Community Center and Charter School. This review includes an analysis of the Eureka, CA climate, temperature, and rainfall averages. These elements of climatic influence will assist in the selection of appropriate plants that fit the project's criteria of edible landscaping and xeriscape principles. In addition this review provides a basic introduction to xeriscape principles and the philosophy of edible landscaping.

Climate Profile of the Region[edit]

The region is often isolated in foggy, wind-sheltered canyons, river bottoms, and north-facing slopes. Redwood groves intermingle with mixed evergreen forests, oak woodlands, and chaparral. Eureka is located in zone 10 according to the USDA Plant Hardiness Zone Map [1]

The average rainfall in Eureka, CA is an estimated 39.45 inch average per year. According to these numbers, the driest month in Eureka is July inches and the wettest month is December.

The average maximum temperature in Eureka is 58.6 degrees. In comparison, the minimum temperature average is an estimated 46.7 degrees. These averages are based off of records for the year of 2012 kept by the Western Regional Climate Center.[2]

Edible Landscape Basics[edit]

Landscaping has evolved in America’s history. Initially highly productive gardens meant to fulfill the nutritional needs of rural families were landscapes main purpose.[3] However, with the advancement of agricultural science, monoculture, and rural flight to urban environments, landscaping lost the need of production and transitioned to an ornamental variety of shaped shrubbery and well manicured lawns. Edible landscaping on the other hand is an approach and practice in which unused, under utilized, and unproductive landscapes are rehabilitated and transformed.[4]The end goal of the transformation is a landscape, which produces various forms of plant species that yield multiple forms of edible foods and goods as well as meeting the need for eye pleasing aesthetics. [3][4]

There are many benefits, which an edible landscape can provide, from rare produce not obtained at your local market to the self-satisfaction of not supporting unsustainable macro monoculture. [5] Edible landscapes are an investment in ones property or neighborhood, by increasing topsoil, nutrient availability, recharging aquifers and more. [6] Edible landscapes can be a misnomer as well, for the goal can also be to attain other harvestable materials such as tea, die, fiber, or medicine. [5]

Appropriate plant selection is based on climate and the zones mapped out on the garden site. The number of plants selected should also be taken into consideration. Gain a perspective on the potential mature size of the plants to determine the space needed to reach its maximum size. [7] Once an initial list of plants has been created. Look into the competitive and may complimentary characteristics of plants that may share a space. Consider the addition of plants that attract pollinators.[7]

Xeriscaping Basics[edit]

Xeriscape gardening is designing a garden that uses minimal amounts of water to maintain the landscape, while complimenting the surrounding environment. Xeriscaping is derived from the Greek word xeros, meaning dry. [8]

The initial step towards understanding the water conservation capabilities on the identified site is to zone areas of water usage. Water usage zones are as follows: high (regular watering), moderate (occasional watering), and low (rainfall is enough). The following step is mapping out zones in relation to sun exposure.[7] If an area is zoned as ‘high’ usage, a number of methods can be applied to the soil to help water retention. Adding organic matter such as compost or leaf litter may increase the plant available water for plants. In comparison, soils that are dry can be tilled to create better aeration.[9]

Water plants early morning or early evening as sun is setting. This will reduce the amount of water that evaporates due to heat and overall it is a practice. Additionally, consider the rate of saturation of the soil (1 inch of watering equals 6 inches of wet soil depth). [10] Mulching serves a variety of needs in regards to soil and weeds. Mulching will keep the soil protected from evaporation and maintain a level of moisture. Mulching also assists in the control of erosion and fighting back weed.[9]

Seven Principles of Xeriscape Gardening[edit]

The concept of xeriscape gardening is comprised of seven water saving principles: planning a design, soil analysis, appropriate plant selection, turf planning, efficient irrigation, mulching, and maintenance.[7]

  • Principle One: Planning and Design
  • Principle Two: Soil Analysis
  • Principle Three: Appropriate Plant Selection
  • Principle Four: Turf Planning
  • Principle Five: Efficient Irrigation
  • Principle Six: Mulching
  • Principle Seven: Maintenance Plan

Create a maintenance strategy that addresses the following elements[edit]

  • Consider the reduction of fertilizer application. When applied, fertilizers assist plants in growth. More growth equals more water needs.[7]:
  • Once plants have been put into their appropriate zones, wait a month of two and watch which plants flourish or establish steady growth. Remove plants that are growing poorly. This will save water and time invested into maintenance.[7]:
  • Avoid pruning.[7]:
  • Control weeds that occur at the base of the plant or in any competitive situation. Weeds also require water and thus will take the water from the intended plants.[7]:

Design and Implementation[edit]

Planning and Design Your Edible Landscape[edit]

There are a number of steps to consider before approaching the design board. You want to gather information about the exposure to element, nutrient, and water holding capacity of your site. Below is the step by step process we followed when implementing our plan.

Solar-pathfinder.jpg
Step 1- Solar Pathfinder

When considering a potential site for edible landscaping the elements will play a large role in designing a successful garden. Use a solar pathfinder to collect points that have the best sun exposure. This will directly assist in choosing which plants are appropriate for your project as some require partial shade and other full sunlight. Below in the ‘Some Extra Tips” section there is a video that will explains how to use a solar pathfinder along with the synthesized results of the JCC site.

Step 2- pH Test

Test the pH of your site. The pH of the soil determines a number of characteristics such as water holding capacity and nutrient availability for your plants. The pH is also important to plants who like acidic soils such as blueberries. Moisten the test area and allow a few minutes for the water to percolate. Make sure not to overwater as you do not want muddled soil. You can then proceed to test the soil with your pH kit.

Soil-test.jpg
Step 3- Soil Testing

Naturally, soil plays a major role in choosing a site as it will determine the nutrient capacity and water holding capacity. We tested our soil with a pH kit as well as an at home clay content test. Collect a soil sample large enough to fit in half of a quart mason jar. Remove all organic matter such as rocks and roots. Fill the other half of the jar with water. Allow the soil to soak up the water and then give it a good shake. Allow the soil and water to sit for about 2 minutes. Hold up a flashlight to see what has settled at the bottom. The particles settled after two minutes are sand. Allow the jar to continue to sit for another two hours. When the two hours are up, shine your flash light into the jar once more. The bottom settled particles are sand, the middle is silt, and the top is clay. This will give you a rough estimate the type of dominant soil structure on your site.

Step 4- Choosing Appropriate Plants

Once you have determined how much sun your site receives and the type of soil you are working with, you can begin to look at a list of plants that are potentially suitable for your site. It is helpful so start with a list of criteria to help you on your research. For example, we determined that we want plants that are low maintenance, hardy, and native. It is also helpful to look up the USDA Plant Hardiness Zone Map for your area.

Step 5 – Pollinators

Consider some pollinators! Your landscape will burst in bounty if you make sure there is plenty of nectar for birds, bees, butterflies, and flies. Consider marigolds as they are lovely and useful as they keep the pests away.

Step 6- Community effort makes any dream come true.

With the help of WCIA, Target volunteers, and Westside community members, we were able to have a successful work day to put in the edible plants, amend the soil, and put in pollinator flowers.

Maintenance[edit]

Some Extra Tips[edit]

Solar-Pathfinder-Analysis.jpg

Using a solar pathfinder is easy and generates great results to help you design your edible landscape. Below is a quick video showing how to set up a pathfinder and collect data. Mike generated a map from the data collected to provide the WCIA with a reference of the sun exposure the front of the building receives for future landscaping.

Lessons Learned[edit]

When working with a non profit there is a level of flexibility that needs to be incorporated into your design. As we set a number for our budget, we quickly realized the project footprint was large and it would take quite a bit of funding for it for it to become a reality. We determined that community donations would be the best avenue to secure a number of plants and materials that were needed.

We received welcoming reactions from local business owners as they handed over a number of plants to our project. However, donors were willing to give us plants of their choosing. So we ended up with a number of plants that fit our criteria but with a few that did not. Working with a non profit community action provides an opportunity for diverse effort input. We want to express gratitude to the donating businesses and Westside residents for their hard work, input, and enthusiasm. We hope that you enjoy the fruits of your labor (literally).

Update October 2013[edit]

Adding beds to the edible landscape
Edible landscape with apple tree
Constructing garden beds
Various berries and artichokes

Upon visiting the site it was evident that the Jefferson Community center has maintained the garden, as well as added numerous new beds and plants. In addition to the initial gardens, 13 new beds have been added, consisting of herbs, kale, arrugala, asian greens, garlic, winter potatoes, onions, leeks, chives, spring lettuce, broccoli, brussel sprouts, strawberries, and various peas. After interviewing the head of the community center, Heidi Benzonelli, we learned that the California Conservation Corps, the Boys and Girls Club, and numerous community volunteers have utilized the edible landscape. The Boys and Girls club in particular, engaged in an intensive eight week summer camp where they built beds, planted new species, and harvested ripe plants. She also stated that the most successful and productive crops have been the blueberries, huckleberries, strawberries, and artichokes. Some of the plants, such as rhubarb, were not as successful and have since been relocated. In the future Heidi plans to add several more beds to the edible landscape with an even greater variety of plant species. Overall, Heidi considers the garden a huge success and a fantastic ongoing educational project for the community center.



Update October 2016[edit]

New stairs and planters for more edible foliage

The Jefferson Community Center is a revolutionary community center that utilizes up-to-date sustainable technology with a unique community model that not only provides for the community around West Eureka, California, but also strengthens the community around them. As of fall 2016, the Jefferson Community Center is expanding to greater heights that will positively contribute to community around them and also others that may move into the community. In addressing issues around the community, the edible food park that Jefferson community is planning to build is a promising solution to those to who are hungry and are not able to afford a meal. This hundred percent, local, native, medicinal, edible, organic, garden will be provided for the community by the community.

Since 2013, the center has grown tremendously! Back in 2013 the organic garden beds were barely getting started, and today they are producing fruits such as strawberries, raspberries and vegetables such as squash and peas. What is truly impressive is the impact the garden has on the community and its members. According to Director, Heidi Benzonelli, the Jefferson Community Center garden provides over a hundred meals to after-school programs. Early Head Start, Head Start, and Seeds are a few examples of the community organizations that are dependent of garden. In interviewing her, she stated that they are preparing to do more for the community in the next couple of years. After interviewing Heidi, the center itself has been preparing for newer additions to the center. With help of Humboldt State University, the Jefferson Center will soon have a new computer lab that will be accessible to the public that are not able to use the computer. Asking Heidi about the community and security of the community center, she stated that the only part in which the community is able to get better if we give them the opportunity to do better, in doing so, Heidi is looking forward for the future remodeling of the Jefferson center that will lead to betterment of not only West Eureka but Eureka as a whole.
