Council warned springs face severe risk; options include riprap, stacked boulders and valve work
Summary
Speakers warned the town’s principal springs could be lost if high‑volume flows carry debris into spring boxes; proposals included reinforcing banks with stacked boulders and concrete, installing or confirming shutoff valves, and isolating spring boxes if necessary.
Members of the technical team and town staff said the springs near the town are particularly vulnerable should a strong debris‑laden flood push through the S‑curve that currently channels water toward the springs. "If we get a huge push of water, I believe we'll lose all 3 of them," Hayden said, describing how a bend in the creek concentrates force on the springs.
Participants discussed options to protect springs including straightening a short reach of channel, stacking boulders and pouring concrete to hold banks, or installing shutoff valves on spring collection boxes so damaged springs could be isolated. Town staff noted that a full concrete cap likely would require hundreds of yards of material, so the favored immediate option is anchored boulders with concrete infill and targeted riprap.
