The information that follows is an outline of some of the projects that OGI has managed in the development of tactical infrastructure. The information does not include every project.

Tactical Infrastructure: Anti-Vehicle Barrier- San Diego Sector- Jacumba Area , CA

Constructed of post and rail, this type of anti-vehicular barrier is used in environmentally sensitive areas. This type of barrier is unique and necessary in remote areas, as it denies vehicle traffic, but does not impede the natural migration patterns of wildlife.

Tactical Infrastructure Primary Barrier: San Diego Sector- Imperial Beach Area, CA

120'x 20' reinforced concrete road surface with 7' footing to the north and a 4' cut off wall to the south. Shown completed with drainage opening and primary barrier. The low water crossing structure was necessary to mitigate the supersaturation of the soil, a swamp area that previously could not be negotiated by law enforcement during rainy periods. This typifies barrier infrastructure in congested areas where metropolitan communities are adjacent to the border, and addresses the unique requirements of mobility, countermobility, and drainage.

Tactical Infrastructure: Primary Barrier, El Centro Sector- Calexico Area , CA

Tactical Infrastructure: Drainage- San Diego Sector, Chula Vista Area, CA (IBWC-4)

IBWC-4: Is a 48' wide reinforced concrete lined channel that is 200' long with one (6) 6X8 multi tube box culvert to the north with a 24' wide road surface and one on the south that is 20' wide. Shown is the northern side of the box culvert with lined channel, guard rails, secondary barrier, all weather road and lights.

Tactical Infrastructure: Drainage San Diego Sector- Chula Vista Area, CA (Box Culvert

A typical multi-tube, border-specific box culvert (shown looking North), many drainage structures have double grates, one on each side, thereby making the structure less vulnerable to breaching efforts from the South. Additionally, the grates are angled upwards, thereby preventing large amounts of waterborne trash from obstructing flow.

Tactical Infrastructure Drainage: San Diego Sector- Chula Vista Area, CA (Box Culvert)

Stewart Bridge : is a 200' x 85' reinforced concrete lined channel with a (6) 8' X 6' Multi tube box culvert with a 20' wide driving surface. This box culvert is unique, as it has electric grates, cat walk, and safety rails. Shown completed, with secondary barrier, and lights (also visible on the right is a bollard-style barrier).

Tactical Infrastructure Drainage: San Diego Sector- Imperial Beach Area, CA (Trapeziodal Drainage)

Whiskey-8: A reinforced concrete outlet and inlet structure connected by a 185' long trapezoidal ditch. A custom trash grate system was fabricated to address the volume of trash coming from Mexico . The grate is mounted on a lift system that can raise the grate to accommodate wastewater being diverted into a wastewater treatment facility.

Tactical Infrastructure Drainage: San Diego Sector- Chula Vista Area, CA (RCP)

Spring Canyon : Four 48” RCPs, with head and tail walls.

Tactical Infrastructure Drainage: San Diego Sector- Chula Vista Area, CA (RCP)

Spring Canyon : Extention of the 60” RCP, with junction box. Also shown, removal of slip-out overburdon to stabilize the existing bank.

Tactical Infrastructure Drainage: San Diego Sector- Chula Vista Area, CA (RCP)

Johnny Wolf Creek: BC-4 is (4) 72” RCP, 240' long with (2) 120' long x 16' high x 2' wide reinforced concrete retaining wall. Shown during construction with 66% of the pipe in place and the south retaining wall started.

Tactical Infrastructure Secondary Barrier: San Diego Sector- Chula Vista Area, CA (Railroad Gate)

E-1 Rail Road Gate: completed rail road crossing with electric gate, cat walk, all weather road and lights. This railroad gate is a seamless component of the secondary barrier.

Tactical Infrastructure: All Weather Road and Secondary Barrier, San Diego Sector- Chula Vista Area, CA

Shown looking west at IBWC-4 with completed primary barrier, secondary barrier, all weather road on the right side of the picture, maintenance road on the left,“V” ditch (Best Management Practices) in the middle, cameras (not visible), and lights.

Tactical Infrastructure: Best Management Practice, San Diego Sector, CA

Best Management Practices are critical erosion control measures, that prevent silt and sediment from eroding into streambeds.
