Background Information:
Halff Associates, Inc. (Halff) entered into a professional services agreement with the City of San Marcos on March 20, 2018 to perform preliminary engineering and environmental assessment services for the Blanco Riverine Flood Mitigation Project. The project is in the final stages of environmental clearance and is ready to begin final design and right-of-way acquisition. Final permits have been submitted.
This Change In Service #4 in the amount of $1,194,262.50 provides funding to complete:
• Land acquisition (appraisals, negotiation, relocation services and closings)
• Design Survey (topographic and boundary)
• Subsurface Utility Exploration and Geotechnical Services
• Preparation of final design plans and specifications for bidding
A later CIS will be required for construction phase services. A cost reasonableness analysis has been performed on this scope in accordance with HUD requirements and found to be appropriate for this $16M construction project.
The current schedule has construction starting in the fall of 2021 for completion before December 2022.
