Project Description

Hays County is located in Central Texas and is a fast-growing municipality with a population of more than 157,000. Hays County had accumulated a considerable amount of deferred maintenance that was difficult to fund through tax dollars. By utilizing their existing budget and 15-year financing with a combination of Qualified Conservation Bonds and Municipal Lease Purchase, Hays County addressed critical facility issues at ten buildings, including the historic County Courthouse and Government Center. 

In addition, renewable energy is part of the project. Solar photovoltaic (PV) rooftop arrays at the Government Center and Jail property is expected to provide a net savings of $2.5 million over a 20-year period. The construction phase of the project is targeted for completion by Spring 2020.
