I-45 Corridor Airport Study

  • In the early 1990’s, Luis provided pro-bono services in the Oak Cliff community’s efforts to implement a major cargo airport in the southeast corner of Dallas County.
  • The effort culminated in a City of Dallas resolution to pursue the project, with the cooperation of the Cities of Lancaster, Hutchins and Ennis, as a major Southern Dallas development. The effort did not come to fruition.

Texas Theater Signage – Historical Asbuilt

  • SGI provided pro-bono design services in the submittal of the Texas Theatre’s Signature Marquee design to the City of Dallas Landmark Commission.
