Planning Commission Meeting Minutes December 11, 2014 Page 9 of 17 McCartney clarifies about parking, number of restrooms, and public spaces. Staff says City Manager asks when doing any review, even a City facility, to use same standards for any other developer. With regard to the standards in the IDDSG (Industrial), this facility is not in compliance with them. This facility is truly an industrial use, not one in the CTC. Brauneis asks about consideration from City green building goals. Russ defers back to applicant, but there are none regarding building code. Applicant Presentation: Dmitri Tepo, Louisville Public Works, Water Resources Engineer. Patrick Rudabaugh, Dewberry Engineering. Tepo presents one slide on Power Point. • The State of Colorado controls and regulates all waste water plant discharges. Beginning August 2017, all WWTP in the South Platte River Basin need to meet tighter ammonia standards. • In 2022, there are new nitrogen and phosphorus regulations. • These improvements will address both regulatory requirements and other minor deficiencies. • Regarding the screening issue on the north border. Typically, WWTP tries to minimize landscaping because there is piping in the ground at these facilities. Tree roots can be a problem. Because of open treatment bas j foliage is another issue. Public Works can work with the drainage project. Commission Questions of Applicant: Brauneis asks about energy efficiency of facilities. Are the ilities meeting standards. Any opportunities available for more energy efficiency. Rudabaugh answers that at a WWTP, 60 -70% of the energy is used in the process itself, roughly 5 -10% in buildings for heating and cooling. Because of the nature of these buildings and because of code requirements on ventilation, even with insulation, heat is going into the air. There is some energy recapture but it is not significant. In this design, premium efficient blowers that are 10 -20% more efficient are being utilized. The control aeration system is also high end with good monitors. They should save cenergy as well. Brauneis asks about occupant comfort and air qualit' beyond code. Rudabaugh says it is considered within reason. They consider safety as well as comfort. Tepo says there have been multiple design meetings with plant operators. Brauneis asks about consideration for green building certification or goals for the workshop primarily. Tepo says the building is designed to meet 2012 codes which are reasonably energy efficient. Because of uses and ventilation requirements, there is just so much that can be done with hot air exhaust. Public Comment: None. Summary and request by Staff and Applicant: Staff recommends approval. Sean says utility needs to be updated to comply. Closed Public Hearing and discussion by Commission: Moline wants to know if the Commission wants to make a condition on landscaping on the north boundary. He is concerned about the piping considerations. Brauneis is interested in the landscaping condition and it be considered.
