Our Sites: Lisbon Dam

This dam is to be built between Acitate Rd. and Afuste Rd. and is extended south across Inca Rd. to Idalia Rd. The storage volume is approximately 60 AF. The outfall is a storm drain across Idalia Rd. down Arizona St. and across Tulip Rd. to the Lisbon Channel. The dam is to be set back from Idalia Rd. so the vertical alignment of Idalia Rd. and the existing gas lines are not impacted. The plan is to re-route Inca Rd. south to connect with Idalia Rd. on each side of the dam. The existing 16” waterline will be relocated following the new alignment for Inca Rd. and along the Idalia Rd. corridor at the downstream toe of the dam.

The approximate area is 15 acres.
