    Alan G. Hill Biography

    Alan has been practicing law in Colorado since 1981, with a focus on water matters since 1986. Mr. Hill has obtained positive results for his clients, including municipalities and special districts as well as agricultural users and developers.

    Mr. Hill’s practice emphasizes water rights litigation, development and protection, including acquisition and sale of water rights. His extensive experience has included obtaining water court decrees in Colorado’s special water courts for appropriative rights of substitution and exchange and approval of plans for augmentation, direct flow and storage rights, substitute water supply plans, and tributary and nontributary groundwater rights.

He has substantial experience in the water courts of Colorado, including numerous trials, and appeals to the Colorado Supreme Court.

    He has obtained water court decrees for municipalities (including the City of Louisville), special districts (including Perry Park Water and Sanitation District, Park Center Water District, Four Mile Fire Protection District, and Cherokee Metropolitan District) and private entities (including Classic Homes, Flying Horse, Rainbow Falls Mountain Trout, Lazy Bull Ranch, Boulder Mountain Lodge, and Case International). Additional services have been provided on an ongoing basis in monitoring and filing appropriate objections to competing water rights claims in various water courts.

    Mr. Hill has negotiated agreements for the multi-million dollar purchase and sale of water rights, for water service and for joint use of water. He has researched and provided title opinions for complex water rights transactions involving water rights, including the sale of water rights, and water rights being used as collateral. These opinions were relied upon by banks, municipalities, special districts, and individuals.

    Acting as general counsel for special districts, Mr. Hill’s services include inclusion and exclusion of lands, negotiation and preparation of intergovernmental agreements, negotiation and preparation of various agreements for the purchase of property, and agreements relating to the special district’s service obligations. He has also represented the special districts in civil litigation.
