Alvin ISD’s board of trustees reviewed the upcoming expiration of the Shadow Creek Ranch tax increment reinvestment zone, or TIRZ, and its impact on the district at its Oct. 20 meeting.
What you need to know
The Shadow Creek Ranch TIRZ was established in 1998 as a 30-year agreement to fund infrastructure through property tax growth, according to district documents.
The TIRZ allowed private developers to invest in infrastructure, including water and sewer lines, and drainage and detention facilities, with the potential to be reimbursed through a portion of the additional property tax revenue generated as property values increased, documents show.
Remember this?
Before development began in 1997, the area that is now Shadow Creek Ranch consisted of 147 separately owned parcels while Broadway Street was a two-lane road that dead-ended near what is now Kingsley Drive.
The original developer invested more than $200 million in infrastructure and land acquisition. Since then, property values within the zone increased from $4.1 million in 1997 to $2.7 billion in 2026. During a 15-year period, housing growth in the area ranked second only to The Woodlands, documents show.
Development also helped spur projects within and outside the zone, including Silverlake Village, Pearland Town Center and medical facilities, documents show.
Breaking down the funding
Pearland manages the TIRZ fund, which collects a portion of the additional property tax revenue generated as property values increase within the zone. Each entity contributes a share of that revenue based on its participation rate.
The different rates include:
Pearland, which participates at a 100% rate and receives an administrative payment to help cover municipal services
Brazoria County, which participates at a 38% rate, which remains unchanged for the duration of the zone
Fort Bend County, which initially participated at a 100% rate, with participation decreasing to 50% through reductions at 10-year intervals
Alvin ISD, which participates at a 100% rate. Of its contribution, 75% is returned to the district to fund schools within Shadow Creek Ranch, while the remaining 25% stays in the TIRZ to cover infrastructure costs
Looking ahead
The TIRZ is scheduled to terminate at the end of 2028 when all existing projects must be completed, with final debt service payments and reimbursements due by September 2029, documents show.
After remaining projects are completed, nearly $3.4 million is projected to remain, including around:
$1.5 million for Alvin ISD
$1.2 million for Pearland
$440,000 for Brazoria County
$224,000 for Fort Bend County
The final amount could change based on the completion of the remaining projects, documents show.
