• Water Utilities (337)
• Utilities In Lieu of Cities
• Collection of Utilities (9)
Growth In Montgomery County
Growth In Fort Bend County

Drafting of Projections
• Identify Cities & Utilities– Cities > 500 pop– Utilities > 280 acre‐feet
• County Projections– TxSDC half or full migration
• Project Cities & Utilities– Estimate utility pop– Based on county growth
Regional Review of Projections
• Regional Review & Revision Requests– Increases required offsets – Over 400 regional revision requests– Over 90% of revision requests partially or wholly adopted
• Other Agency Stakeholder– Texas Parks & Wildlife Division– Texas Commission on Environmental Quality– Texas Dept. of Agriculture
Review of Projections: Region C
• Over 280 municipal entities in region
• Area Stakeholders
• Analyzed build‐out limits
• Redistributed growth
Development of Projections: Region H
• Coordination with Regional Groundwater Update Project
• Projections on 1 square mile grid
• Evaluation of the ability to develop areas
• Overall projections similar to TWDB Draft.
