Construction phase services included shop drawing review, contractor meetings, review of payment applications and construction as-built, for the 411 Main Project.  This project consisted of the extension of San Saba Street for a half-block to provide parking, sidewalks, streetlights, landscaping and other aesthetic features as part of improvements in downtown Round Rock.  Construction phase services included the addition of a retaining wall and a sidewalk, along with a subsequent submittal to TCEQ.

Construction phase services included shop drawing review, contractor meetings, review of payment applications and construction as-built, for the widening of Gattis School Road from west of Rolling Ridge Drive to west of Via Sonoma Trail (0.5 mile).  The proposed improvements include curb removals, sidewalk relocation and re-striping to accommodate the addition of a two-way left turn lane for local access.

Construction phase services included shop drawing review, contractor meetings, review of payment applications and construction as-built for TxDOT to secure approval for a turn lane and access driveway for the Shops at 685 development. Project included ROW dedication determinations, environmental documentation, utility identification and coordination for relocation efforts, roadway design, storm sewer design, traffic control plans and completed permit request with required information. 

Construction phase services included shop drawing review, contractor meetings, review of payment applications and construction as-built for Mager Lane improvements from FM 1660 to the east City Limits of Hutto.  Project elements included right of way acquisition, utility coordination and adjustments, pavement design, storm sewer design, floodplain mapping and revisions, culvert design and channel improvements as well as normal roadway design tasks. 

Construction phase services included shop drawing review, contractor meetings, review of payment applications and construction as-built. For this shopping area along the Loop 1 (Mopac Expressway) near US 183 in Travis County created congestion issues on the northbound frontage road due to patron traffic at the center’s access points.  As a joint effort between TxDOT, the City of Austin and the developer, frontage road improvements including widening and re-striping to create acceleration and right turn only lanes for the shop’s access driveways were designed.  Tasks include geometric layouts, roadway design, drainage design and striping plans compatible with the existing frontage road and meeting all TxDOT design requirements. 

During relatively intense rain events, Oakridge Drive in the vicinity of Chisholm Trail Middle School (approximately 1000 feet west of Deep Wood Drive) experienced inundation that hindered traffic or even completely blocked the road. Additionally, storm water at times overwhelmed the culvert capacity under Creekview Drive near the Round Rock West Greenbelt (approximately 300 feet west of Deep Wood Drive) causing inundation of the road and flooding of adjacent property. The purpose of this project was to reduce the street inundation/property flooding frequency at these two locations. SLG determined the most feasible, cost effective solution for these flooding issues by analyzing and modeling the existing drainage conditions and looking at possible alternatives. Ultimately, the solution was presented to the City for concurrence and PS&E documents were developed for construction.
