Client: Discovery Green Conservancy
Location: Houston, Texas, U.S.A.
- Site Development
The pre-development condition of the current location of Discovery Green Park, a high profile, 10+ block land mass, presented multiple challenges. Work was financed from multiple sources, completed under a compressed schedule, and executed with restricted access. Environmental concerns were related to historic use/impact within an Urban Core setting and included multiple Areas of Concern (AOCs) within the Pathway of Construction (POC), including numerous “ghost” storage tanks and large areas of impacted media. TGE was responsible for all environmental aspects including the removal of thousands of tons of soil impacted above regulatory limits. Likewise, during ongoing construction, the site required permitted dewatering and regulated management of tens of millions of gallons of discharge. The combined property also required full Texas Risk Reduction Program (TRRP) case closure under Texas Commission of Environmental Quality (TCEQ) purview.
Downtown Houston Park Redevelopment
Due to project size and scope, initial “buy in” of all parties was critical. TGE was selected following a rigorous pre-qualification process due to our extensive history in successfully executing similar urban care projects. TGE prepared a project plan that integrated multiple service lines, leveraged vendor relationships, drew upon pre-construction regulatory agency concurrence experience, and relied upon a solutions-based process in conveying information to the board and construction prime. All historical use “artifacts” (tanks, abandoned sumps, below-grade equipment, etc.) were located ahead of construction and documented, affected areas were delineated and plan requirements met. Once construction commenced, TGE installed compliance well points and began extended groundwater monitoring. While local soil removal was required and in situ remediation performed for the site, the location of the subgrade, multi-level garage proved of benefit in expediting case closure due to extensive dewatering of the area to reach closure objectives.
TGE remediated and “clean-closed” the urban park on time and under budget; the park now enjoys unrestricted “residential use” requirements.
