Trash Consolidation and Tire Recycling

Large amounts of trash are carried from the Los Laureles Canyon into natural habitats during rain storms every year when the water flow mobilizes loose trash. Trash booms or other capture devices are created to prevent plastic waste from reaching natural habitat, where removal becomes more problematic and costly. The WC staff is developing strategies to consolidate and remove trash as it enters the Tijuana River Valley through the use of new and existing mechanisms. In addition, the WC staff is also promoting commercial tire recycling in the San Diego- Tijuana region, although it is uncertain at this time who will create the facility for recycling. In working closely with both the County of San Diego and the California Integrated Waste Management Board, the WC staff  is exploring a range of possibilities in creating the recycling facility including following up on progress already made by an entrepreneur who conducted preliminary investigations on the viability of establishing a movable recycling plant that could be used on both sides of the border. While progress has been made, the largest challenge in establishing the recycling  plant lies in its financial viability. The first step to the success of this project is monetary aid to further research and implementation.

Tire Reutilization Designs

A large number of waste tires make up a significant percentage of the trash flow from Tijuana to the United States. To reduce the number of waste tires, reusing the tires in various civil engineering projects reduce the number of tires washing down the canyon. In addition, reusing the tires in projects such as building retaining walls will also contribute to erosion control. Local workshops will be created and facilitated by the WC staff in order to train local residents, community leaders and organizations, and employees of the City of Tijuana to reuse tires in sustainable ways. These workshops will include hand-on-training for specific projects, such as building retaining walls, as well as educational information on the various ways to use waste tires. This project will partner with Mexico’s municipal, state, and federal government agencies, including local organizations that specialize in tire re-utilization activities. With this project, the WC Staff will expand this technology and knowledge of tire reuse to other regions of Tijuana.

Preventing Sediment from Entering the Reserve

Erosion control methods will reduce the amount of soil runoff but will not completely eliminate erosion. As a final step before the sediment flow reaches the Reserve, sediment basins are installed to capture the soil. Regional landowning agencies on both sides of the border need to install and maintain sediment basins to minimize the sediment flow into the protected areas. Efforts will focus on planning for the installation of a series of sediment basins in key locations throughout the lower watershed, including: Smuggler’s Gulch, Yogurt Canyon, and other various locations in the City of Tijuana. These sediment loads flowing from the canyons of  Tijuana will be captured in the basins and will be effectively managed by the WC staff and regional agencies. The hurdles of this program lie in its funding and lack of agency coordination and planning for the sediment basin installations.

Secure Conservation Easements in Urban Canyons in Mexico

Pollutants carried by storm water from the canyon into the Reserve pose a threat to the protected area’s natural and native habitat. To prevent invasive species and damaging pollutants from coming into the Reserve, a buffer must be created between the two regions to limit the environmental consequences. A vegetative buffer would be created near the border in order to filter storm water and sediment before it crosses into the United States. The buffer would be built in the open spaces of Los Sauces, Los Laureles, and Matadero Canyons because of their ideal location between the countries. The City of Tijuana has never designated areas as buffers before, which makes this project a model for future conservation needs. The open space to be designated for vegetative buffers are not land acquisitions, and thus are owned by various owners both private and public. As a result, the owners of the property will continue to have responsibility of their individual properties and also collaborate with the WC Staff with long term care and maintenance of the buffers. By creating a vegetative buffer, it will reduce the environmental impact of pollution to the reserve and increase conservation.

Erosion Control in Los Laureles Canyon

One of the main concerns in the Los Laureles Canyon and the reserve is the erosion in the canyon flowing to lower elevations, in which the reserve is located. This erosion and sediment build up will harm the growth of native species in the area and is a loss of precious rich soil which could be used in the canyon for agriculture. Primary solutions are implemented to prevent erosion at the start including the use of pervious pavers and the re-vegetation of hill sides. Pervious pavers are permeable concrete blocks that distribute rain water evenly on soil and channel remaining runoff water into storm drains to prevent soil runoff. [Read more…]

Border Field State Park Day Use Area Construction

Most of you have been to Monument Mesa, seen the condition of the “park” and wondered why the park manager still has a job. It’s a desolate, dry, brown field with picnic tables and barbeques that are beat to a pulp. Some of you may recall State Parks’ 2006 attempt to spritz the place up by adding a group picnic area with enormous concrete shelters that provided a new nickname: “Stonehenge.”

Fortunately, they cracked during construction and were torn down. Very few of you vaguely remember decades ago when there were new picnic tables and lush green turf. Families enjoyed spending the day up there with the spectacular 270 degree view. Well, as the old song goes, happy days are “near” again! By late July 2010, we will start renovation of the Monument Mesa Day Use Area. It should be done a few months later, in fall 2010.

The project includes:

  • An unstonehenge-like group picnic area, covered with a similar shade sails system that we use at the Tijuana Estuary Visitor Center. The group facility will hold 2 groups of 30 people.
  • A turf area and native plant gardens.
  • Eight additional picnic sites.
  • Upgraded educational panels that better explain the estuary and cultural significance of the site.

We think this will attract more people to Border Field State Park, resulting in more people falling in love with the estuary and more advocates for its protection and further restoration. Unfortunately, until we can find $4 million to raise the entrance road, even this renovated Monument Mesa will not be accessible to the pubic by vehicle for part of the year due to flooding. (This season’s closure was especially long because of a major leak in Mexico). Now, if only we could just get 4 people to donate a million bucks, we’d be golden.

Community Cleanup Event at Border Field State Park

2014TRAM

Who:  Surfrider Foundation – San Diego County Chapter, the Tijuana River National Estuarine Research Reserve, and YOU!! All ages are welcome. Volunteers under 18 yrs of age must have a signed waiver by parent or guardian. Volunteers under the age of 16 must be accompanied by a parent or guardian.

When: Saturday, February 20, 2016 from 8:00 am-12 noon.

Where: Goat Canyon in Border Field State Park. 1500 Monument Road, San Diego, CA 92154

Why: Help us clean up one of the most environmentally degraded areas in San Diego County! Goat Canyon is a wash that lies directly north of the US/MX border. Trash, sediment and waste tires routinely travel across the border and into this wash with every rain event. Every scrap of trash and discarded tire we remove from this area equals that much less waste that enters the estuary, beaches and ocean.

What to wear/bring? Volunteers must work in long pants and boots or sturdy, closed-toe shoes. We also recommend bringing sunscreen, sunglasses, and hats. Work gloves, tools, water and a light snack will be provided.

Event to be followed by a complimentary volunteer appreciation lunch, location TBD.

Pre-registration is required. Click here to sign up today!

 # Please note that the date and location of this event are subject to weather considerations and may be changed if a rain event occurs or is predicted within 72 hours of the event time.
