The Southern Sandoval County Arroyo Flood Control Authority(SSCAFCA) Lisbon Pond Project Received the ACEC New Mexico Engineering Excellence Award.
“Vital infrastructure projects like this one bring meaningful protection to many Rio Rancho residents and help give residents peace of mind during the next storm,” SSCAFCA Executive Engineer David Gatterman said.
According to SSCAFCA, the $1.2 million project created a 42-acre-foot dam with an embankment height of 8 feet and a 9 acrefoot auxiliary pond downstream from the dam to capture portions of the watershed that bypassed Lisbon Pond.
It is located at the intersection of Inca and Afuste Roads just north of the Star Heights neighborhood.
SSCAFCA says the area is known for damaging erosion, which has caused flooding issues for residents.
They also say Lisbon Pond was built to protect neighborhoods, roads and two high-pressure gas lines that serve northern New Mexico from flooding due to rain runoff from intense storms.
Profile and embankment modifications to two roads were also made: a 30-inch storm drain that routes the outflow from Lisbon Pond and the Auxiliary Pond, and a downstream shotcrete channel connecting to the Lisbon Channel.
The project was funded by a grant from the Federal Emergency Management Agency and SSCAFCA Bond funds, according to SSCAFCA.
