  • Represented Colorado municipal and water providers in USDA Forest Service proceedings which proposed the imposition of “bypass flow” or other conditions that would have affected the reliability or yield of existing water supplies during the renewal of Federal Land Policy and Management Act authorizations for associated water supply facilities. Clients’ facilities were reauthorized without such conditions and reauthorization decisions were upheld on appeal.
  • Assisted clients in obtaining various local government approvals for large pipeline projects crossing multiple jurisdictional boundaries.
