Background

The Jefferson Project is an amazing example of hope. The Jefferson Community Center (JCC) used to be the Jefferson Elementary School, but it has become a safe haven for the community, young and old, in Eureka, California, thanks to the community volunteers from the Westside Community Improvement Association (WCIA).

The first goal of the project was to redevelop a small patch of land at JCC that has become over-saturated with water and swampy into a native plant garden. Since 100% of the rainwater that is collected by the community center is maintained onsite and drains to one area, the flat swampy area would need to be redesigned to allow better water drainage. To do this, we would need to first excavate a dry creek bed and fill it with gravel, which creates a path of least resistance for the water, i.e. better drainage. We would then need to build up mounds in the area around the creeks so that plants with low water needs can be further raised above the swampy water, allowing the plants to thrive.

The second goal of the project was to create educational signage for the native plants and outreach to the community, giving them a chance to be involved in the Jefferson Project. This entails painting signs on the stone wall behind the area in question with signs that highlight native plant species, giving some background on their historical/cultural uses locally. Since part of the Jefferson Project's mission is to involve the community, part of our job is reaching out to people in the community to be involved in this process, as well as the first part of the project.

The project for this Spring 2017 semester is located on 1000 B Street, and our team will be collaborating with Heidi Benzonelli-Burden, Monty Caid from Lost Foods, Bill Rodstrom and Pete Haggard of Native Plant Society, and Lonny Grafman. The team consists of Humboldt State University’s Engineering 305 Appropriate Technology students Richard Moog and Kathrine Sanguinetti, the project’s "Build and Educate Team" who will help with "Jefferson Native Park Design."

Problem statement

The objective of this project is to build, grow, and cultivate a space with native plants to reduce the use of water, manage the onsite rainwater that is available, create signage to help guide community members and visitors, and outreach to educate and unite the people in Eureka and other parts of Humboldt County. This project aims to create a space that is inviting, educational, and fun for all people who will visit the Jefferson Center and be part of something that will continue to grow for future generations.

Project Evaluation Criteria

The following Criteria will be used to assess the success of the project. These criteria were chosen with the help of Director Heidi Bennnn and the students designing the Native Landscaping Project. The scale (1-10) represents the importance of each constraint meeting the criteria where 1 is the lowest and 10 is the highest.

Native Landscaping

Native

First, it is important to define the term native and what is considered a natural range for a species to ensure there is proper understanding and selection of plants during the native landscaping. Native refers to the specific origin or region of a particular species.[1] A native species is one that occurs naturally in a specific region and is a product of natural forces without human interference and (for North American plants) has been growing in the wild before European settlement began around 300 years ago.[1] Determining the natural range is not always as straightforward as it seem; it is defined by the area that a species naturally grows in, which can be interrupted heavily by humans.[1]

Benefits and Advantages

Native landscaping and planting with natives comes with many benefits and advantages. Native plants often have a natural defense system against disease and insects in the area they grow, taking away the need for pesticides which helps to keep toxins out of waterways.[2][3] Once the plants are established, they need only minimal irrigation, keeping water usage at a low.[2] Wildlife also uses native plant communities as a natural habitat, which attracts pollinators and preserves the balance of natural ecosystems.[3]

Planting and Maintenance

Fall or winter is the prime time to plant because the soil is softer and rain is more frequent, and planting after March requires extra supplemental watering in order to establish a healthy root system.[4] [2] Adding 3-4 in. of compost to the top soil before planting is beneficial for nutrient intake. In terms of spacing, it is suggested to place trees 10-15 ft. apart, shrubs 5-10 ft. apart, and ground covers 1-3 ft. apart.[2] To maintain plants that have recently been transplanted, it is important to water them deeply and frequently for the first two summers to support healthy growth. Once established though, native plants only require watering during the driest parts of summer.[4] Plants may be moved to a different location if they do not appear to be thriving well to where they will do better. It is also important to pull weeds by hand so the weeds do not rob the native plants of any nutrients, especially in the beginning.[2]

Landscape Design

The goal of landscape design is to use natural features of the area blended with foreign elements to create a landscape that is both ecologically sustainable and aesthetically pleasing. The three main factors to consider when designing an ecologically sustainable garden are the climatic, cultural, and ecological conditions of an area. To reach sustainability, resources have to be treated not as expendable commodities, but rather as a system that should balance inputs and outputs. For design purposes, small plants should be placed where they will not be blocked out by sun and where they will not be blocked out of vision by larger shrubs. (around the edges of the garden).[5]

Mounds

To look natural and serve their drainage function, mounds (or berms) should be large enough (in surface area) and gently sloped so that they have a more natural appearance. They are particularly useful in drainage. To be effective, they must be gently sloped enough to support plants and not erode with rainfall and other natural conditions. They should not be taller than about 24 inches and should be 4-6 times as long as they are wide.[6] A diversion ditch may also be advisable, with at least a minor downward grade leading away from the site to be drained.[7]

Soil

One thing to consider when preparing a site for landscaping is soil quality. It is important to watch out for poor water drainage and compaction. Properly drained soil should be an even mix of solid material and surrounding space, which can be either water or air. An excessive water table can be problematic because it promotes anaerobic conditions. Soil quality can be diminished if topsoil is removed and not replenished.[8] Many parts of the Klamath region of California have a high density of igneous rocks, which has a high impact on ecosystem growth. Trees under these conditions are often more spread out and fail to be very productive.[9]

Dry Stream Beds

A dry stream bed is a stone-lined channel that mimics a natural stream. Small boulders and cobble are placed along the meanders as if a water force placed them there[10]. Natural stream beds will widen on the bends at erosion points.[10] Erosion is the removal of soil from the impacts of water, wind, and ice. Over time, these forces will wear away the soil.[11] One of the factors of stream erosion is the change in stream flow, causing boulders that are too large for the current to remain in the middle of the stream or along deposition points (where stream flow is slowest), while smaller ones are washed to the sides.[10] This information is key for understanding where to place boulders and cobble along the dry stream bed and how to shape it.


Regional Climate

“Geographic features such as topography, altitude, proximity to the coast, and latitude to a certain extent define a local area’s weather patterns.”[5] Eureka is known to be a very coastal environment, with very low altitude in the area we will be working. The specific site we are working in, due to the water collection and drainage system in place, resembles and mimics a riparian habitat. In general, the temperature of the region fluctuates very little from season to season and the rain season is very long and almost persists throughout the year, though it drops in the middle of summer.[12] Fog and low clouds are prevalent and so it might be unwise to use plants that have high sun needs. Based on evapotranspiration patterns, there will generally be soil moisture until July in the Humboldt coastal region. The North Coast subregion of the NW California region supports marsh, coastal scrub and fir forests.[13]

Educational Signage

Signage will be a key component of the project, so it is important to understand what makes signs effective and favorable. Signs are important to give an outdoor learning center an identity.[14] They can be simple or complex, they just need to be clear and are best when they represent the character of the community.[14] Most of the attention to signs is from first time visitors, though repeat visitors are known to reread signs when the signs have desirable information, aesthetics and location.[15] Motivators for reading signs are the signs’ location (if they are easily visible and in a natural stopping point), interest in the topic, and relevance to the area they are representing.[15] An ideal sign should have a three-dimensional image of what it is representing, a large title, should show something that cannot easily be seen (such as something underground), and should be located at a natural stopping point.[15]
