Amarillo City Council members will have a full agenda Tuesday, but the biggest decisions center on long-term infrastructure projects worth tens of millions of dollars.

The council is scheduled to consider nearly $22.3 million in engineering agreements for future wastewater treatment plant expansions, along with more than $7.3 million in Federal Aviation Administration grants for improvements at Rick Husband Amarillo International Airport.

Before the public meeting begins, council members will meet in executive session at 1 p.m. to consult with attorneys regarding pending landfill fire claims. Open session starts at 3 p.m.

Among the largest items on the consent agenda are two engineering agreements with Kimley-Horn & Associates for Phase 2 planning of the Hollywood Road II and River Road II wastewater treatment facilities. The projects, totaling more than $22 million, will fund pre-design work, conceptual planning and cost modeling as the city prepares for future wastewater system expansion.

Airport improvements also account for a significant share of Tuesday's agenda. Council members are expected to consider accepting more than $7.3 million in FAA grants to update the airport's layout plan, modernize its baggage handling system and design a new Aircraft Rescue and Firefighting simulator. The city would provide the required 5% local match using airport revenues.

Several other purchases are also slated for approval, including a three-year, $584,464 contract with Samsara Inc. for a new GPS system covering 959 city fleet vehicles. The system will replace the city's existing tracking platform and allow departments to monitor vehicle location, speed and idle time to improve fleet management.

The council will also consider an $80,000 contract with Habitat for Humanity to build a new home at 1110 N. Monroe St. using HOME Investment Partnership and Community Housing Development Organization funds. Other proposed purchases include nearly $115,000 for replacement automated external defibrillators, about $50,000 for new wildland firefighter protective equipment and a $99,900 aquatic market viability study to help evaluate future recreational water facilities.

Outside the consent agenda, several public hearings are expected to draw attention.

One proposal would rezone property near Triangle Drive and Lakeside Drive to allow a specific use permit for an asphalt or concrete batching plant.

Council members will also consider adopting the city's 2026-27 Annual Action Plan for Community Development Block Grant and HOME Investment Partnership funding, as well as a resolution establishing the Rock Ridge Public Improvement District.

Another item would make the City of Amarillo the authorized agent for regulating on-site sewage facilities within city limits. While septic systems have long been regulated through Randall and Potter counties in partnership with the city, approval of the ordinance would transfer that authority directly to Amarillo.

The meeting will also include discussion of proposed updates to the city's boards and commissions appointment process, possible changes to the city's organizational structure, a recap of the Red, White, and Boom celebration, and a fiscal year 2026-27 budget update.

The meeting begins with a proclamation recognizing Wonderland Park's 75th anniversary and a recognition honoring the city's Water and Sewer Team before council members move into the day's business.
