City Council Meeting Minutes November 18, 2014 Page 4 of 16 He noted there has been a lot of public communication about the delay of replacing the bridge. He acknowledged the process has been slow and has frustrated residents. The City staff is working closely with the Federal Highway Authority (FHWA), the Colorado Department of Transportation (CDOT), the State of Colorado, and Community Development Block Grant Funding (CDBG) to ensure a 100% reimbursement along with a streamlined process to construct the bridge in a timely manner. He noted as federal dollars are being requested the approval process for the design goes from the city to the state and to the federal government levels. Public Works Director Kowar explained the presentation represents a 30% completion of the design. There are four design concepts for the 95th Street Bridge replacement, which can be achieved with the City's budgetary resources. Staff will confer with CDOT to determine what they will fund. He introduced the design team: Michael Baker, David Nemovitz, who have prepared the technical design and made the environmental and hydraulic analysis, and Patricia Meier of PKM, who developed the project aesthetic concepts. David Nemovitz thanked Council for the opportunity to present the plan options for the bridge. The presentation will share the background for the decisions and present two decision points for the City Council. Those two decisions are the bridge and the shoulder widths. He explained the cost of the project is reimbursable through the following partnerships: FHWA (80 %) State (10 %) CDBG (10 %) City (0 %) Total $2,923,682 $ 365,460 $ 365,460 $ 0 $3,654,602 Project Schedule: • November 2014 • December 2014 • January 2015 — • August 2015 — • March 2016 - — Present to City Council (30% completion of concept design) — Present to CDOT /FHWA Conclude Preliminary Design /Update Council Advertise for Construction Complete construction, re -open roadway Mr. Nemovitz recognized two items: 1) Understanding the hydraulics of the bridge before and after the flood; 2) elaborate on the hydraulic analysis to examine the design concepts and alternatives to develop the bridge and to determine the preferred option. He referred to a slide, which illustrated the 100 -year flood plain. He noted the flood plain expands when it nears County Road and the channel banks are not tall enough to contain all the water where the ground is very flat. He noted the proposed project will provide an improved hydraulic solution at the bridge, but will not fix all the overtopping of the road with the 100 -year water elevation (Bella Vista, County Road, 95th Street or Community Park). The flooding would still occur, but the bridge would remain safe.
