Summary

Director Lucas Raley presented population projections showing an addition of about 80,000 people in the city’s full planning area over 10 years and 74,000 in the reduced water service area; he noted state law changes that could reduce future build‑out and said the city has already added 36,000 of the projected 80,000.

Lucas Raley, Director of Planning, told the MCDC board the city’s population as of Jan. 1 was about 237,000 and that models project roughly 80,000 additional residents in the full planning area over the next 10 years. He explained the department also modeled a reduced water service area scenario (driven by recent state law changes affecting extraterritorial jurisdiction) that would add about 74,000 people in 10 years and yield a reduced‑area total near 307,000.

"Existing population as of January 1 was 237,000. The projection for the full planning area for that 10 year period is, approximately 80,000," Raley said. He described the methodology (a combination of projection models and a 10‑year rolling average of 6,000–8,000 new residents) and noted the city added 13,000 last year; of the projected 80,000 the city already has 36,000 in completed or in‑development units.

Raley discussed implications for impact fees and infrastructure planning, noted uncertainty about future state law changes, and said build‑out tapering could occur earlier for a reduced service area (as soon as 2032) versus the full planning area (potentially 2044). Board members asked clarifying questions about charts and whether bars represented population or units; Raley confirmed the charts represented population and explained the conversion from units using typical persons‑per‑unit assumptions.
