ICMA's Program Excellence Award for Intergovernmental Cooperation recognizes outstanding programs developed out of cooperative actions or strategic partnerships between government organizations. In 2005, ICMA presented one of two awards in the 10,000-to-49,999 population category to the towns of Parker and Castle Rock, Colorado, and to former Parker Town Administrator Aden Hogan Jr. and Castle Rock Town Manager Mark Stevens for the Joint Sales Tax Self-Collection Program. Through a joint sales tax agreement, the two jurisdictions realized a combined net gain of $2.7 million in tax revenue the first full year of operation. Learn more about ICMA's Annual Awards program.
