This 1.5 mile segment of Evans Road is an existing two-lane asphalt road that has partial flooding and inadequate roadway conditions with insufficient capacity to serve current traffic volumes.
The County CIP project scope for the Evans Road segment improvements is divided into two separate phases.
- Phase I - Replacement of an existing flood hazard/low water crossing located approximately in the middle of the project segment with a 350 LF five-lane, pre-stressed concrete I-beam bridge crossing that provides unflooded access. The relocation of water and sewer mains to accommodate construction of the new bridge crossing.
- Phase II - Reconstruction and expansion of the roadway from two-lane to four-lane with a center turn lane to meet current standards of the major thoroughfare plan classification. The roadway expansion also required widening portions of the existing ROW that necessitated acquisition of certain property.
Both phases of the CIP project are located within environmentally sensitive areas—including the Edwards Aquifer Recharge Zone, protected species habitat areas, and potential historical/cultural interest areas.
CDS Muery provided civil engineering and surveying services for both phases of the CIP reconstruction project, and construction administration services for Phase I. Other CDS Muery services included:
- ROW acquisitions coordination
- Contracting and management of subconsultant specialty design services
- Government regulatory permitting
- Design modifications to existing flow-way section and drainage structures within FEMA floodplain
- Traffic control planning coordination
- Existing underground and overhead utility coordination and relocations
- Planning/design for multi-phase construction sequencing
The specific services provided by CDS Muery for both phases included:
- Control and topographic surveys
- Parcel/ownership deed research
- ROW acquisition base maps/plats
- Tree survey and inventory plans
- Roadway/pavement/drainage design
- Structural bridge design

- Storm water hydrologic/hydraulic modeling and analysis
- Water quality BMP design
- ADA accessibility design
- Construction document plans and specifications
- Design phase construction cost estimating
- WPAP and SWPPP permit plans
- USACE NWP 14 and FEMA CLOMR application submittals
Required reviews and approvals for Phase I were obtained from Bexar County, COSA, SAWS, ACOE, FEMA, THC, TCEQ, TDLR, and CPS/AT&T/TWC.
