Blanco Road: Hildebrand to Jackson Keller

This project is the design of 2.5 miles of Blanco Road from Hildebrand to Jackson Keller. The existing roadway consisted of four lanes (two in each direction) with associated curbs, sidewalks, and limited insufficient drainage and traffic signals. The roadway was designed include four lanes with right and left turn lanes at major intersections, upgraded curbs, sidewalks, retaining walls, storm drainage system and upgraded traffic signals. A Tree Inventory and Protection Details, SW3P, Sequence of Work, and Traffic Control Plan were part of this project.

Our engineers were responsible for developing, designing and cost estimating the storm sewer system. The storm drainage system included three separate storm sewers ranging in size from 24 to 60-inches and single box culvert systems ranging from 4 feet x 3 feet to 6 feet x 5 feet. The storm drainage systems outfalled to the Olmos Creek and an existing three barrel 8.5 feet x 8 feet MBC. As part of the design our engineers demonstrated that there would be no adverse downstream impacts to the existing conditions. The design was coordinated with existing utilities to eliminate conflicts. Design included factors such as existing land use (commercial and residential) and project conditions, utilities, construction impacts, construction costs, and ROW acquisition.
