 Environmental Assessment - Fanta Fe, NM

Tierra conducted cultural resource studies and developed an Environmental Assessment for the City of Santa Fe and the Santa Fe National Forest for vegetation treatments in a 2,100 acre portion of the Pecos Wilderness located within the City's watershed. Due to years of fire suppression, fuel loading in the forests surrounding Santa Fe has greatly increased, and the aftermath of wildfire on the watershed now poses the threat of clogging the City's municipal reservoir with ash and silt, threatening the water supply of the City. The Environmental Assessment and associated resource studies that Tierra developed will assist the City and the Forest in reducing the risk of wildfire and the threat of subsequent damage to the City's water supply.
