Chapter I Falfurrias HWY 281 Checkpoint – Civil Design Analysis

I-1

1.0 Site Analysis

1.1 Existing Conditions

The project site lies approximately 14 miles south of Falfurrias, Texas along the northbound side of Highway (HWY) 281. The tract encompasses approximately 26 acres of real property. The property is currently owned by the Ed Rachal Foundation and King Ranch although exact property lines have not yet been determined. The southern portion of the site, roughly 6 acres, is the current residence of the U.S. Customs and Border Protection, Falfurrias Checkpoint.

The site is triangular in shape with an estimated ±5900 linear feet of Hwy 281 frontage and a width of 348 feet. The site is bound by Texas Department of Transportation (TxDOT) right-of-way (ROW) to the west, and the easements of Tennessee Gas, high pressure gas lines, to the east.

The site, at the ROW, sits approximately 8 feet lower than the existing Hwy 281 grades with some depressions that are 15 feet lower than the highway. This will require substantial fill. We will let the site sit approximately eight feet lower than Hwy 281. This design would need, at an estimated, 90,000 cubic yds.

Other than electricity, there are no current utilities, that will be utilized for the new site. Further explanation is addressed in this document.

Phase I demolition will encompass clearing and grubbing of the undeveloped portion of the site along with the relocation of some existing light poles, from the current site. Phase II demolition will remove all existing checkpoint facilities and Phase III demolition will remove all temporary commercial ingress. We are currently working out the final details and will include on the next submittal.

1.2 New Site Layout

Because we were limited on site width, we have taken the Baker 12-Lane Site Standard Layout and adapted it to fit the new site. The adaptation will affect the Short Stay Kennel. We will not be able to provide the full yard as developed in the kennel standard. The site will be designed to construct an 8-lane checkpoint with the expandability to a full 12-Lane Checkpoint. The site will need to be designed and constructed to limit or nullify any impacts to the existing checkpoint activities.

Because we will have to work around current checkpoint activities, we will need to construct a temporary commercial ingress to the new checkpoint, until we are able to demolish the existing checkpoint and construct the new commercial ingress in its place. The temporary ingress will be constructed just south of the non-commercial ingress.

I-2

1.3 Stormwater Management (SWM)

The project will include approximately 27 acres of impervious roofs, roads, and parking that will significantly increase runoff rates and volumes. We will retain the 100yr storm event onsite however. There will be areas that will drain offsite, as shown in the plan set. These areas will follow current drainage patterns and will not increase the existing drainage quantities, of those areas. The 100 yr event was chosen to not only provide the site with fill material from their excavation, but to also mediate the effects of the increased runoff on the neighboring site. The necessary retention was calculated to be 17,755CY. We have provided 17,795 CY. The event chosen for the basin was more to provide fill for the site than it was for actual stormwater measures.

2.0 Grading

Site grading shall maintain grades between 1% and 5% to allow for adequate accessibility and drainage. Grades less than 1% are allowable for concrete gutters and pervious pavement. Minimum grade for concrete gutters, if used shall be 0.4%. Pervious pavement is encouraged for reduction of storm water runoff and shall be designed to grade at 0.25%. Grades in excess of 5% may be required based on the final elevation of the site. If grades in excess of 5% are required for efficient site design all designs shall comply with applicable ABA standards for accessible design. All grade breaks in excess of 4% shall be designed for a smooth transition and allow clearance for vehicles with low clearance.

3.0 Pavements

The pedestrian sidewalks throughout the site shall be at least 5 feet wide and 4 inches thick non-reinforced concrete. The facilities shall be constructed of heavy duty pavement consisting of (9) inches of unreinforced Portland Cement Concrete (PCC) for the commercial lanes and (7.5) inch unreinforced concrete for the non-commercial lanes.. All accel/decel lanes, within TxDOT ROW shall be placed in (11) inches of reinforced PCC to meet TxDOT requirements. The GOV parking area will be heavy duty, non-reinforced concrete. Concrete pavement sections have been developed by Geotechnical Engineers and methodologies are explained further in the Geotechnical Report.

4.0 Storm Drainage

4.1 Storm Frequency and Rainfall Intensity

I-3

The storm drainage runoff was calculated by the rational method based on a design storm frequency of 25 years for onsite areas, and a frequency of 25 years for systems that will receive offsite flows. Because of grading requirements, we will have to accommodate the runoff from Hwy 281 and provide space in the infiltration basins.

4.2 Drainage Patterns

4.2.1 Existing Drainage Patterns

Existing runoff currently drains from west, center of Hwy 281, to the east, King Ranch. With a major portion of the existing residing on site in a low point of the property.

4.2.2 Proposed Drainage Patterns

The intent of the proposed drainage system is to maintain generally the patterns, through storm drains or as sheet flow to infiltration basins. These basin areas will infiltrate all storm waters.

Roof runoff from the buildings will be conveyed by underground roof drain systems that will direct flow towards the infiltration areas. Overflow from the basin areas will follow same drainage pattern to King Ranch.

The area around each building will be graded to direct drainage away from the buildings towards the infiltration basin areas, swales or storm drain system.

Swale and surface inlets that only receive onsite flows were designed for the 25-year storm event; facilities that receive flow from offsite were designed for the 25-year storm event.

4.3 Storm Drainage Structures

Manholes and surface inlets will be constructed of reinforced concrete or pre-cast concrete. Structures in pavement will be designed to handle H-20 loading.

Structures in turfed areas will be constructed for lighter weight loading. The construction contractors will have the option of using concrete pipe, corrugated steel pipe, corrugated aluminum alloy pipe, PVC or corrugated PE pipe for the underground storm drain culverts. The infiltration areas will be planted with native species of turf. The site storm drainage calculations were performed using Storm Cad. In addition to inlets being sized to accommodate either 25-year storm events, drainage ditches computations were calculated for capacity and shear stress in order to select the proper erosion control blanket.

4.4 Stormwater Rationale

I-4

Basin volume provided was calculated using a Modified Rational Method with IDF values obtained from the Texas Department of Transportation. To aid in our calculation we have given a conservative estimate of outflow of 0.30 CFS/ac.

This would allow a conservative outflow estimate that would provide for a basin large enough to provide much needed fill for the checkpoint site.

Infiltration basins were designed using an estimated 1 inches of infiltration per hour. With that, we estimate that it would take approximately four days for the basin to drain. This may be an extended period, but, with the size of the basin, it would have the capacity to handle sizeable back to back events, if they should ever occur.

The storm drain system was developed using Stormcad with the results of the HEC 22 Headloss Details and Combined Pipe/Node Reports provided in the appendix.

Outfall Rip Rap was designed using the provided USGS Tables to assure we have provided the minimum required rip rap necessary. However, we have exceeded what was required of USGS.

5.0 Utilities

5.1 Water Supply and Distribution

5.1.1 Existing Water Supply

The existing facility is currently served by a water well. This water well is approximately 3000 linear feet away from the new facilities. This well will be abandoned and a new well or two will be drilled for this site. This will be accomplished through a performance specification in the contract.

5.1.2 Existing Water Distribution System and Demolition Requirements

This water well will be abandoned in Phase II of the demolition process.

5.1.3 New Water Distribution System and Service Lines

This project will require the addition of one or two wells. The exact location cannot be determined, at this time. This will not be known until construction, but we will provide the contractor with areas that the wells can be drilled. These wells will need to accommodate both fire and potable water. We do not know what the quality of the water will be, so, water may need to be treated or potable water

I-5 delivered, to facility.

5.1.4 New Fire Sprinkler Distribution System and Service Lines

Fire flow calculations have not been addressed, for this submittal. We will provide a 30,000 gallon fire water tank and pumps to accommodate fire flows. This tank will be filled with the installation of the water wells.

5.2 Existing Sanitary Sewer System

There is an existing septic system, because of its proximity to the new facilities, will not be adequate for use. It will be demolished and removed in Phase II Demolition. The demolition will need to meet all Texas Commission on Environmental Quality (TCEQ) requirements for abandonment.

5.2.1 New Sanitary Sewer System and Connections Points

The new sanitary sewer system will be either an aerobic septic system to handle all administration and dog kennel facilities. It will be designed to meet all Texas Commission on Environmental Quality (TCEQ) Requirements. A small packaged lift station may be needed to accommodate the kennel. This will lift the refuse, to meet a typical depth of flow, to the new septic system. This system will be added to the immediate south of the administration building with surface application in the bioretention area, south of the primary commercial lanes.

Calculations have been provided in the civil appendix

5.3 Landscaping Irrigation

Permanent landscape irrigation shall not be installed for this project. Temporary irrigation may be installed by the contractor to ensure vegetation is established.

5.4 Gas Supply and Distribution System

There is no natural gas for this facility

6.0 Fencing

There is existing hog-wire, t-post, fencing along the entire east side of the property. This fence will need to be removed by Phase I and Phase II Demolition and new fence constructed.

6.1 New Fencing

Hog wire fencing shall be installed around the eastern side, of the site.

I-6 standards.

7.0 Turfing and Landscaping.

Site, where required will be planted with native grasses. Because of the nature of the operation, no trees will be incorporated, into the design.

Chapter III Falfurrias HWY 281 Checkpoint – Architectural Design Analysis

III - 1

1.0 General Description. The United States (U.S.) Customs and Border Protection (CBP) was created within DHS as the single agency responsible for securing the Nation’s borders. CBP, with the primary mission of homeland security, is responsible for securing and controlling the Nation’s borders to prevent terrorists and their weapons from entering the U.S. The Border Patrol (BP) is an office within CBP.

The U.S. Border Patrol (USBP) utilizes a number of different facilities to provide support for enforcement activities, including: BP Sector Headquarters (HQ);

Border Patrol Stations (BPS); Checkpoints and Forward Operating Bases. A BP facility may be a stand-alone facility or co-located with other CBP/DHS facilities.

The primary design element of a BP Checkpoint BPS is the Checkpoint building.

This building contains the administration, alien detention and staff support areas that together support the Checkpoint’s operations; and the secondary Storage Building. The exterior spaces at a Checkpoint include space for primary and secondary vehicle inspection lanes, exterior support areas such as tool and traffic control storage, a Non-Intrusive Inspection (NII) area, and Government Owned Vehicle (GOV) parking. The view from the Checkpoint building to the primary inspection areas must be unobstructed.

Checkpoint design must incorporate effective security measures that ensure safety for both the staff and surrounding neighbors and protect sensitive information and pilferable property and vehicles. The Checkpoint design should not arouse feelings of insecurity within the neighboring community through exposed use of severe barriers and other protective measures commonly found in correctional institutions. The design must use tasteful architecture and screening elements to reduce the negative visual impact of security measures and BP operations, while also communicating the fact that the facility is a law enforcement facility, that trespassing is not permitted, and that official business is welcome.

1.1 The design for this facility includes two fully enclosed structures, the primary Checkpoint Building with Sally Port and the secondary Storage Building; plus a number of open structures which include the Short Stay Kennel, Commercial Vehicle Inspection Canopy, Non-Commercial Vehicle Inspection Canopy, Mobile Non-Intrusive Inspection (NII) Vehicle Canopy, Secondary Inspection Commercial Canopy, Secondary Inspection Non-Commercial Canopy, Vehicle Lift Area Canopy, Fuel Island Canopy and two Bus Shelter type structures.

2.0 Criteria References. All design and construction work are required to comply with, at a minimum, all applicable building codes, standards, zoning codes and ordinances adopted by Government and local jurisdiction in effect at the date of contract issuance. Unless a specific document version or date is indicated, criteria shall be taken from the most current references as of the date of issue of

3.2.2 Primary Inspection Canopies:

Each canopy shall extend a minimum of 100’ from the front face of the inspection booth into the traffic approach lanes. Inspection booths are placed on the driver’s side of the vehicle and towards the rear of the canopy to allow the canines and their handlers’ shaded access to the vehicles in queue. Inspection booths are placed in a staggered fashion so as to allow for visibility of all booths from the Checkpoint Building. The non-commercial inspection lanes are 15 feet’ wide and have a 5 feet wide curb-less median between them. All commercial lanes except the over-sized load lane are 17 feet and have a 5 feet wide curb-less median between them. The over-sized load lane is 25 feet wide. The median spaces allow for placement of inspection booths, license plate readers, cameras and other equipment to provide agents better views of the commercial vehicles. The medians between lanes are protected by bollards and painted demarcation lines.

Passive vehicle crash barriers are placed at the front of the medians to protect agents and the canopy structure from vehicle impacts. Crash barriers are designed based on State DOT standards and design speed limit. A K4 rated crash barrier is located in the median in front of the checkpoint building, to protect the front of the building from runaway vehicles. Commercial Inspection canopy size is approximately16,050 square feet for Phase-1, and 22,870 square feet at full build-out. Non-commercial Inspection canopy size is approximately13,630 square feet for Phase-1, and 19,800 square feet at full build-out. Minimum clear height under the canopies is 18-feet.

3.2.3 Secondary Inspection Canopies:

Per the USBP Facility Design Standard all secondary inspection lanes shall be 14’ wide and have a 6’ wide curb-less median between them. However, the USBP Facility Design Standard Room Data Sheets shows the commercial inspection lanes as 15 feet wide, with 6 feet wide median, and the bus lanes at

f. Roof drainage shall be accomplished with interior drains tied to downspouts located at the columns.

6.0 Deviations. Deviations from the Checkpoint Baseline Design Requirements must be approved by the U.S. Border Patrol Facility Design Standardization Committee.

The following deviations from the Checkpoint Baseline Design Requirements have been approved:

a. Revise the locations of the following spaces in the Checkpoint Building – mechanical and electrical rooms, janitor’s closet, staff female and male toilets.

b. Revise the layout of the staff female and male toilets to provide more fixtures

(2 each urinals and water closets, 3 lavatories) in the male toilet. Reduce size of female toilet and janitor’s closet. The staff female and male toilets are not in compliance with ABA criteria, however the building is technically in compliance with ABA criteria, since a unisex toilet in public waiting area (Document Inspection Waiting) is ABA compliant. Staff or visitors needing ABA toilet facilities will have to use the unisex toilet in public waiting area.

c. Add an interior window to Interview Room 450 38

d. Reduce the size of the Evidence Processing Room at the Storage Building.

e. Use space gained from Item-3 above to add an ABA restroom in the Storage

2.0 General Structural Background

The Falfurrias Border Patrol Station site is located at Texas Highway 281 approximately 14 miles south of Falfurrias city. This is a region with relatively

IV-2

high wind load design requirements because of the proximity to the Gulf Coast and likelihood to experience hurricanes. The International Building Code (IBC) 2012 Basic Wind Speed (3-second gust) design value for this area is 135 mph.

However, the site is in an area of low seismicity. Since we have only preliminary soil report, we are assuming a seismic site class definition of “D” for the soil.

Using Site Class D for this location as defined in the IBC, along with the mapped probabilistic ground motion values for the 0.2 second period, (Ss) = 0.084 and for the 1.0 second period, (S1) = 0.020, then structures for this facility will be classified as Seismic Design Category “A”. A table of preliminary structural design values is listed below.

The preliminary geotechnical report indicates the need for controlled fill to elevate the site to the required elevation. Also, it recommends using a stiffened slab-on-grade (rib-mat) for the station building, storage, and kennel building at this facility. All canopies columns will be supported on spread foundations and their floors will have regular paving that will be shown on the civil drawings. In order to mitigate the effects of the expansive soil and reduce the PVR, the preliminary geotechnical report recommends removing several feet of the expansive soils and building up the site to the required elevation with properly compacted select-fill.

Special inspections of fabrications and on-site construction will be conducted in accordance with the requirements specified in the 2012 International Building Code (IBC).

3.0 Description of Structural System

Administration Checkpoint Building The design team has carefully considered the structural systems for the new Border Patrol Station in Falfurrias, Texas. The structure for the administration building will be one story high. Since final soil report is not available at the present time and we understand the building will be constructed over large amount of fill, we anticipate the foundation of this building to be either rip-mat (a stiffened grid type beam and slab-on-grade) supported on well controlled compacted fill or concrete drilled piers with one way elevated structural slab. For building framing, large portion of the building at the middle (detention corridor) requires clearstory with high ceiling. Therefore a moment gabled frames in the north south direction spaced at approximately 30 feet have been selected. There will be beams spanning between the ridges and the eaves of the frames with purlins supported by these beams to support steel roof deck and roofing. A drop ceiling will be over the offices and full clear story over the detention corridor. The walls will insulated concrete panels. The lateral loading will be resisted by the gabled frames in the north south direction and with the concrete east west direction. There will be no load bearing or structural supports inside the building.

Canopies

IV-3

There are four main canopies, primary inspection commercial canopy, primary inspection non-commercial canopy, secondary inspection commercial canopy, and secondary inspection non-commercial canopy. All canopies will have pre-engineered steel framing for the roof and supported by either spread footings or drilled concrete piers. The floor for all canopies will be regular paving that will be shown on the civil drawings.

Short Stay Kennel Building The Kennel will be framed with load bearing masonry walls with steel roof framing. The building will be supported on rip-mat foundation (a stiffened grid type beam and slab-on-grade).

Secondary Building The storage building will be framed with pre-engineered steel framing and will be supported by rip-mat (a stiffened grid type beam and slab-on-grade). The building will have loading dock at its west side with dock levelers.

Communications Tower The communication tower will be pre-engineered structure and will be supported by concrete mat foundation.
