4 The City of Aurora Stormwater Division is responsible for the cleaning and maintenance of the City s curb inlets, storm drains, detention ponds, and storm channels. Some of these activities include: removing sediment and vegetation from channels, easements, forebays, and ponds; revegetation associated with channels and ponds; maintaining fall protection devices near stormwater infrastructure; flood monitoring and management; and snow removal. The Stormwater staff exceeded their goals per the Federal Emergency Management Agency (FEMA) and the National Pollutant Discharge Elimination Standards (NPDES) requirements for sediment removal of ponds & channels. All 68 miles of earthen and 8.5 miles of concrete channels were cleaned of debris & trash, 74 ponds & 222 trouble spots were maintained monthly and after each storm event, graffiti was power washed and/or painted, 4,79 inlets were inspected and 115 inlets cleaned. Stormwater crews cleaned the Binney Water Treatment Plant s forebay, responded proactively to several storm events that impacted Aurora, completed grading and reseeding activities at Rampart Reservoir, removed sediment from Conservatory Pond, removed accumulated sediment from Piney Creek near the intersection of Arapahoe and Liverpool streets, developed and implemented a private water quality pond research program, regraded and reseeded several locations disturbed during the evaluation of the Rampart Waterline s condition, completed several small sediment removal projects, continued to focus on the removal of noxious tree species in channels, provided support for the Highline Canal Cleanup and Household Chemical Roundup, and dedicated significant efforts to the operations required to maintain the stormwater system. During 212, members of Stormwater focused considerable energy on enhancing communication and teamwork. Two consultants provided support and members of the team played an active role supporting the communication and teamwork efforts throughout the year. The Stormwater Division s commitment to excellence was verified when the level of planned maintenance exceeded the Division s maintenance goals and staff responded proactively to numerous challenges. The Division remains strong, well organized, and committed to being cooperative, responsive, and efficient when addressing the operational activities associated with stormwater management, responding to customer service inquiries and requests from the public and providing operational support for other Aurora Water divisions and other City of Aurora departments. Respectfully, Joe McCleary Superintendent of Stormwater Operations

20 It is with great honor that I bring to you the 212 Annual Report for the Wastewater Division. In 212, the division experienced another outstanding year in the amount of work accomplished. The division produced 4.6 million feet of wastewater collection lines that were cleaned, 61, feet of wastewater collection lines inspected and 963 repairs were done to the wastewater collection system. All of this work resulted in having zero sanitary sewer overflows and only two municipal sewer stoppages in 1,41 miles of wastewater collection lines. This feat is a direct reflection of the dedication and work effort of the entire Wastewater Division. I would like to express my thanks and gratitude to the entire staff of the Wastewater Division for making 212 a very successful year. Coby Shurtleff, Wastewater Superintendent
