surrounding area photossiteThe CROSS \ TOWN station SWIG site is just to the west of downtown Las Cruces. Between downtown and the site is a historic neighborhood of single family homes, a small freight railyard and some industrial development. The site is bounded by Hayner Avenue on the north and Amador Road on the south. Amador is a heavily trafficked through street connecting the west side of the city, downtown and the burgeoning east side. Just to the west of the site is Valley Drive—a primary north/south street. The east side of the site is bounded by the Armijo Lateral—a large irrigation canal that serves agricultural land to the south of the city.

The immediate context of the site is primarily industrial in nature. Most land use to the north, east and south is light industrial. To the west, along Valley Drive, the land use is commercial. Immediately northwest of the site is a public park, Branigan Park.

As the nature of industry and manufacturing in the Dona Ana County area changes from agrarian and light manufacturing to government support and technology, older parts of the city that once supported these industries are being transformed. Structures originally built to house industrial operations are now being taken over by a small but enthusiastic arts community that embraces the funky character of the area. An art cooperative and an aerial dance company now occupy two buildings to the northeast of the project site.

The site has several existing structures, primarily large simple timber framed sheds clad with corrugated steel panels. The site also has a loading dock that was alongside a former rail spur, a structure containing a cotton press, a steam power plant and a water tower that was part of an on-site fire protection system. Several of the existing structures are being removed due to deterioration.

transit oriented developmentThe site is about one half mile from a new multi-modal transit center being constructed at Lohman and Alameda. Existing bus service runs along the Amador just south of the site and Valley just west of the site. An existing informal bike path runs alongside the Armijo Lateral to the east of the site. The city of Las Cruces is aggressively developing a bike path system along all of the irrigation canals that cross the city to make biking a viable alternative mode of transportation throughout the city.

A long term goal for the community and region is the development of passenger rail service between the city of Las Cruces and the city of El Paso. If this becomes a reality the site will be well situated to take advantage of that resource.

Las Cruces NM CONTEXT 01

project introductionThe development team proposes construction of a new seventy-two (72) unit mixed affordable and market rate housing community— CROSS \ TOWN station—on the SWIG property in Las Cruces, New Mexico. Its proximity to downtown, community resources and transit services make for a unique opportunity to achieve an urban, transit oriented development.

The site is approximately three quarters of a mile west of Main Street—the historic center of Las Cruces. It is separated from the downtown government and retail center by a beautiful historic residential neighborhood, a small freight railyard and some light industrial property. It is within walking distance to schools, shopping, financial services, and the new intermodal transportation hub of the City bus lines. Multi-use infill development potential allows for a blend of housing options (high density single and multifamily-market rate and affordable), along with specialty retail and dining, commercial, and light industrial manufacturing.

The project will provide efficiency, one-, two- and three bedroom apartments to support a diverse community. The wide range of unit sizes will provide flexibility and allow for individuals, couples and families. It will serve both affordable and market rate segments.

CROSS \ TOWN station will incorporate design elements and have a special set-aside of units for homeless veterans and participate in the Department of Housing and Urban Development (HUD) and Department of Veterans Affairs Supportive Housing (HUD-VASH) program. This program helps eligible homeless veterans find and retain stable independent housing by partnering HUD Section 8 vouchers with Veteran's Administration Supportive Housing case management services. Case management provides ongoing support and monitoring of VASH veterans in the community to promote and foster the veteran's growing independence, recovery, and success as they transition back to living in the community. Having a place for veterans to live in one area creates a supportive community. With the support of this program veterans will be able to have a common area to meet, and a place to hold support groups.

The design of the project will provide accessibility, mobility, and livability features for veterans with special needs as well as other residents—nearly every unit will be visitable. A space that serves as a large community living room, a separate interior space for events, an additional space dedicated for use by veteran residents and several outdoor spaces provide places for the residents to come together and community bonds to form.

master plan narrativeAs part of the design process for CROSS \ TOWN station, the design team developed a master plan for the entire twenty-six acre SWIG site. The SWIG master plan seeks to create the framework for a highly sustainable new urban neighborhood that supports the downtown area and the city as a whole. The plan integrates land use and transportation planning. It accommodates and anticipates diversity of: use, housing types, age groups, incomes and transit opportunities. It is walkable and bikeable. The plan recalls the historic neighborhood planning model exhibited in Mesilla and other local communities. The SWIG master plan seeks to revitalize the area by building a world class neighborhood.

The site for CROSS \ TOWN station was selected so that the affordable housing development has a prominent place alongside the new park. CROSS \ TOWN station is integrated into the neighborhood in a way that expresses the importance of affordable housing.

The site has an unusual shape that provides an interesting challenge for the design team. This portion of the site is also therefore slightly less valuable to the master developer. This land can be purchased for a better price—which makes sense for affordable housing—while keeping the more regular, and more valuable, parcels within the developer’s portfolio to maximize its profit potential, and promote mixed income development.

master plan conceptsA | connect to and extend the existing street gridThe project extends Sweet Street south from Hayner into the site. The first phase of development—CROSS \ TOWN station—will leave this extension as a cul-de-sac. In the future Sweet will be extended farther and connected to a new north/south through street from Amador to Hayner on the east side of the site.

B | preservation of historic structures and cultureThe project seeks to maintain a connection to the “roots” of the place. It is hoped that water tower, loading dock and press tower can be preserved. The water tower will become an icon for the neighborhood and serve to

anchor a new park or village square. The loading dock expresses the former use of the site and forms the eastern edge of the development along the Armijo Lateral. Due to its scale and length it could be used in any number of ways from truck loading for new light industry to a platform for market activities such as a farmers market or local arts and crafts market. The press tower recently lost its steam powered compress but it could provide a memory of the original buildings and contain an interpretive center about the agrarian history of Las Cruces and Doña Ana County.

C | street grid with walkable blocksThe street grid is configured to create walkable blocks similar in size to those of historic downtown Las Cruces. The through street on the east side of the site is oriented parallel to the Armijo Lateral. Cross streets are mostly perpendicular to the through street. Streets are to have a sixty foot right-of-way.

D | outdoor spacesThe project recognizes Branigan Park to the northwest of the site as a significant amenity and seeks to provide a direct connection from the center of the new neighborhood to the existing park. Similarly, the Armijo Lateral and the land alongside it are important to the identity of the neighborhood. A new park in the center of the neighborhood provides a town square and a home for the water tower. A direct connection is planned

between the new park and Branigan Park. A new linear park along the east side of the site takes advantage of the bike path along the Armijo Lateral as a place to walk, stroll and bike.

E | building massBuilding mass should form “walls” defining street edges. These walls define outdoor urban “rooms”. Buildings will be constructed alongside the street with minimal setbacks. Parking is to be on-street or behind buildings. Building height is related to width of right-of-way. Three or four stories structures are encouraged on the SWIG property. Building mass is supportive of an active street life and provides visual interest when walking down the street.

F | CROSS \ TOWN station siteThe first phase of development—CROSS \ TOWN station—should occur at the northwest corner of the SWIG site. This portion of the site was selected for the following reasons:

• good vehicular access via Sweet and Hayner• proximity to existing utilities beneath Hayner• it is close to an existing bus stop at Valley and Hadley (about four blocks to the northwest)• it is close to retail services along Valley Drive, including a grocery store at the intersection of Valley and

Hayner• alongside Branigan Park for complementary use by resident families with older children

design narrative | architectureThe buildings at CROSS \ TOWN station are created with simple, linear and repetitive forms that recall the functional architecture of the industrial built environment that surrounds the site. Nearby buildings are large in scale with shallow gable or shed roofs and often with strong blank walls clad in galvanized metal panels. At CROSS \ TOWN station the massing of the structures recalls the long unadorned sheds of the neighborhood.

Buildings at CROSS \ TOWN station are single loaded to provide ventilation and light through the units. Unit plans are comprised of simple, elemental volumes—one for living spaces and one for sleeping and bathing spaces—that are shifted and interlocked in various ways to create one-, two- and three bedroom units. Each unit has a deep alcove off the circulation system to create a “front porch”. On the street side of the buildings the shifting results in an equal and opposite deep recess. Windows are placed within these recesses to take advantage of more favorable sun shading conditions that reduce solar gain within the units.

The projecting volumes of the plan are clad in corrugated metal. Because window placement is in the sides of the projection, rather than the outward face, the blank metal clad walls of these volumes recall the appearance of the industrial context. Exterior walls at the back of the recesses are clad in stucco in rich deep colors providing a softness that contrasts with the tough outer shell of metal.

Buildings at CROSS \ TOWN station relate primarily to the orientation of the street. This creates numerous challenging solar orientations for fenestration. In response, window

placement and sunshades vary relative to their orientation creating variety in the elevations of the buildings.

The north end of building one faces the proposed park that contains the water tower. This is the heart of the new neighborhood and the street facade of the building one is given a special treatment in recognition of the civic nature of this space. This portion of the building has a continuous wall punctuated by deep punched openings. It is clad in painted metal panels to provide a crisp, elegant appearance yet still stay within the industrial aesthetic of the project.

A section of the volume of building one is removed at the ground and second levels to allow a path connecting the parks to pass through. The third floor extends across the void to create a large covered outdoor plaza that will provide a shady place for events during the hottest parts of the year. Its location at the juncture between the residential property and the public park allows it to serve both the residents and the larger neighborhood community. This covered outdoor space recalls the roofed truck loading areas at nearby buildings.

The building volume at the ground floor on the south side of the plaza contains community spaces. It is pulled back slightly and rotated away from the street by a few degrees to face into the center of the new neighborhood park. An event space with large expanses of glass provides views onto the plaza and into the park and will be available for residents of CROSS \ TOWN station and the surrounding neighborhood.

site and building elevation strategyThe site is practically flat sloping gently from east to west, dropping 2’ over a distance of 500’.

All ground floor units have been raised 2’ above the adjacent outer perimeter sidewalks; roughly 2’-6” above streets, driveways and parking lots. As a result residents will feel less intruded upon by passing traffic. Grade at exterior of the building is set at EL 100’, placing ground floor elevation for all units at EL 102’.

All units’ entry doors face into the courtyard, whose perimeter walkways’ elevation is set at EL 102’. The project’s roof line slopes into the courtyard, enabling the harvesting of rainfall which will be collected into a turfed retention pond at the south end of the space with a low point of EL 100’-6”.

space planningThe individual units at CROSS \ TOWN station are designed around a high-ceilinged, open, airy central space containing living, dining and kitchen functions. The kitchen is located in the center of the space with an area for dining on the circulation side of the unit and the living/family space on the opposite. This unique arrangement makes the kitchen—often truly the “heart” of the home—the center of activity in the unit. It allows individuals working in the kitchen to be a part of activities taking place in the living area. It also allows for better light and cross-ventilation through the unit. Kitchens are often located on one end of the unit, making it difficult to get a large window on the end wall for light and airflow. By shifting the kitchen to the center, both end walls of the units are free to have large openings.

Kitchens at CROSS \ TOWN station have a linear organization that eliminates corner cabinets that are difficult to use. The island countertop is wide enough to provide space to tuck stools beneath. Residents who want to use this as their dining surface do not need a dining table and can use the dining space for a desk or home office, or a second seating area.

The entry door of every unit opens from an alcove off of the exterior egress balconies. This small space provides a transitional semi-private zone between the shared circulation zone and the private interior of the unit. The space allows each resident to have their own “front porch” that can accommodate a potted plant or chair. The space in front of the unit encourages residents to sit, interact with and get to know their neighbors. This provides security for the property and builds the bonds of community.

Air Sealing Installation Methods: Before drywall:

1. Seal bottom plate of exterior walls with caulk or gasket; seal inside edge with caulk after walls are up.

2. Seal band joist with caulk, spray foam or gasketing between top plate and band joist and between band joist and subfloor.

3. For bathtubs on outside walls, insulate the exterior wall and air seal behind tub with sheet goods or plastic before tub is installed. After the drain is installed seal the tub drain penetration with sheet goods and caulk or spray foam. Note that the use of paper-faced backerboard that meets ASTM mold resistant standards is acceptable for exposed walls and behind fiberglass surrounds. It is not acceptable for use behind tile.

4. For dropped ceilings or soffits, duct and flue chases and open partition walls, use sheet goods and sealant to stop air leakage from attic into soffit and then insulate. Alternatively install framing and drywall for the soffits after installing the taped ceiling drywall.

5. Caulk the backsides of window flanges to the sheathing during installation.6. Seal between door thresholds and subflooring with caulk.7. Seal window and door exterior rough openings with backer rod and caulk, or use non-expanding

latex-based spray foams that will not pinch jambs or void window warranties.8. Seal all electrical wire, plumbing and HVAC penetrations between any conditioned and

unconditioned spaces with caulk or spray foam.9. Seal wiring and knockouts in electrical boxes with caulk. Also seal outdoor mounted boxes to

the exterior sheathing.

During drywall:1. Seal drywall to top and bottom plates using gaskets, adhesive or caulk.


After drywall:1. Seal electrical switch, outlet and circuit breaker boxes to drywall with caulk or foam.2. Seal light fixture boxes, medicine cabinets and bath and kitchen ventilation fans to drywall with

caulk or foam.3. Seal all duct boots to floor or drywall with caulk, foam or mastic.4. Seal any plumbing or electrical wire penetration through drywall with caulk or foam.5. Seal around the metal flue of combustion equipment using a UL-approved metal collar and high-

temperature fire-rated caulk.6. Use only UL-approved airtight, IC-rated recessed light fixtures (that meet ASTM E283

requirements); seal between fixture and drywall with caulk.

Air Seal Exterior1. Repair any damaged pieces of sheathing.2. Seal all exterior penetrations, such as porch light fixtures, phone, security, cable and electrical

service holes with caulk or spray foam.3. If not using air barrier, seal all sheathing systems with manufacturer’s approved tape or caulk.

Appropriate air sealing shall be performed to ensure that each unit’s air infiltration upon completion is less than 2.0 ACH50, as determined by the final air infiltration test performed as part of the final HERS inspection.
