Under Drains  - The standing Underdrain Committee meetings have resumed and the group is hoping to have this finalized by the end of the year. The proposal would include a fee of $60 per lot plus $24 for review by CSU. HBA met with the City and Utilities and is still looking for another pilot site. Contact John at HBA if you have a site that might serve as a pilot for installation of the test system. 

Draft Standardized Street Cross Sections  – NEED VOLUNTEERS TO HELP WITH COST ANALYSIS - CSU has developed a number of proposed standardized or model street cross sections. HBA is looking for members to review these and provide comments prior to the next working group meeting.VIEW CROSS SECTIONS   PLEASE PROVIDE YOUR COMMENTS TO BRUCE ZOOK AT SPRINGS UTILITIES bzook@csu.org WITH A COPY TO JOHN KISIEL AT HBA.
HBA IS ALSO LOOKING FOR OTHERS BESIDES ENGINEERS (EXCAVATORS, PROJECT MANAGERS, ASPHALT AND CONCRETE SUPPLIERS) TO REVIEW THESE DOCUMENTS AND BE PART OF A SMALL COMMITTEE OVER THE NEXT FEW MONTHS. PLEASE CONTACT JOHN AT HBA IF YOU CAN HELP OUT WITH THIS.

As part of this issue, Colorado Springs Utilities has identified as one of the major challenges they continue to struggle with is coming up with utility locations within the new street cross sections. Specifically, finding a location and design for the stormsewer in relation to the wastewater trench slope envelope. According to CSU standards, the stormsewer can not be installed within the wastewater trench slope without a variance. In reviewing the new street cross sections it is apparent that there are probably no residential streets that could be designed with stormsewer and wastewater in the same street without a variance. This will be cumbersome and time consuming for both CSU and the design engineers to handle all of these designs with variances, thus CSU has looked for a way to design stormsewer inside the wastewater trench envelope and the only alternative we could identify was to allow the use of plastic stormsewer where the stormsewer was being installed inside the wastewater trench envelope.

One key concern with this "pre-approved variance" voiced by the industry continues to be - "How much is this going to cost?" CSU is looking for someone in private industry to come up with some installed cost comparisons between RCP and plastic stormsewer. HBA is asking for a volunteer to work on compiling installed cost of a sewer system composed of RCP vs plastic pipe up to a size of 36". CSU proposes stopping at 36" because at this point it is the largest size approved by City Engineering. Alternatively you might want to go up to 48" as this may be approved in the future as more experience is gained with plastic stormsewer in this area.

PLEASE CONTACT JOHN KISIEL AT HBA IF YOU WOULD BE ABLE TO HELP WITH THIS ISSUE.

Proposed Water Modeling Process Changes - Utilities is proposing changes to the water modeling process. The proposal would place the responsibility for providing the Hydraulic Analysis Report to Utilities to assess the impacts and system demands of the proposed development on the water distribution system. This is in a preliminary draft stage and Utilities is seeking comments about the proposal. Please review the attached documents and forward comments and questions to Lisa Barbato at Utilities with copies to John at HBA.
