Full report
Doña Ana County has moved to advance a $5.40 million wastewater collection expansion in Chaparral, approving a $364,540.94 engineering task order with Bohannan Huston for Phase 3C of the community's sewer improvements.
The task order, approved on the consent agenda, covers final design repackaging, permit coordination, bidding administration, construction administration and observation, record drawings, closeout documentation and GIS onboarding. County staff said its approval was required to secure rights-of-way and permits needed for the county's readiness-to-proceed submission to the Colonias Infrastructure Board.
The Phase 3C project will install new sewer pipeline and manholes in the Chaparral Lift Station No. 6 service area, alongside associated roadway demolition and reconstruction. The collection-system design had previously been completed, but the new assignment will update construction drawings, contract documents, cost estimates and the project schedule, then take the scheme through procurement and construction support.
The New Mexico Finance Authority approved $5,395,904 for the project in June: a $4,856,314 grant and a $539,590 loan. The loan has a 20-year term, a zero-interest rate and a 0.25% administrative fee component, producing a 0.25% net effective interest rate. The county is required to verify a $539,590 match as part of the funding conditions.
The authority required the county to submit readiness materials by October 31, including an expenditure drawdown schedule, approved plans and specifications, evidence that rights-of-way, easements and permits have been secured, and an executed fiscal-administrator agreement.
County project material identifies 382 residents as beneficiaries. It states that connecting residences to the centralized system would allow onsite septic systems to be decommissioned, reducing groundwater-contamination risk. The planned engineering construction phase has a 540-calendar-day contract period from authorization to proceed.
