West Corridor UpdateMay 10, 2007

Since March Meeting

RTD received a request in early April from the jurisdictions to postpone five VE items until the May board meeting.

•Federal Bridge

•Ped Bridges & Bike Path through the Park

•Single Track to Jeffco

•Changes to Drainage Plan

•Sheridan Station/Bridge

In Addition

•Auraria has request additional review time for the Auraria station changes

•Denver has requested RTD look at moving the Decatur station – as part of a Transit Oriented Development (TOD) opportunity.

Federal Blvd. Bridge

Action: Further analysis with the CM/GC determined the barrel vault structure type is not feasible in this location. This is no longer a VE item.

Current proposed structure type will be precast concrete box girder.

Status: Need concurrence from CDOT and Denver on new design, CDOT on increased cost of bridge replacement.

Ped Bridges and Bike Path in Parks

Original VE proposal was to eliminate the three pedestrian bridges through the park section in Denver. Also proposed to change the bike path material from concrete to asphalt.

Action:

Park Pedestrian bridges won’t be eliminated and bike paths won’t be changed.

RTD to cover $1 M of ped bridges

Park Mitigation Funds to cover $1 M of ped bridges

Park Mitigation Funds to cover delta of $.5M for bike path

Status – These VE proposals with stated changes are going to the RTD board on May 15

Single Track from DFC to Jeffco

Single Track is an RTD operational issue, not a service level issue for Jeffco

RTD was planning 15 minute frequencies with double track, no change with single track

Ridership forecasts don’t warrant a change in headways until after ???

Headways of 10 minutes could be attainable with additional passing track east of Colfax– estimated cost $3 million (2006$)

5 minute headways require double track, and additional bore under I-70 (estimated in Year ????) RTD will ensure that CDOT not preclude second bore if and when I-70 is rebuilt at this location.

Original plan was to bring all drainage improvements in the corridor to the 100 year eventIssue: RTD cannot afford this in all locations and has proposed alternatives

VE proposal to consider changes to design criteria

– Will adhere to local jurisdiction and UDFCD design standards as a minimum

– Maintain track and station operational effectiveness

– Not impact adjacent property or public safety

–Meet the requirements of the 100 year FEMA flood plan

Changes to Drainage Plan

Drainage Plan

Status:•Met with stakeholders on March 27

•Met with Denver and UDFCD on April 10 and May 8th to focus on resolution

•Continue to work with affected parties to discuss specific concerns

•Meetings continue to focus on individual area drainage issues

The original plan was to raise Sheridan Blvd and place light rail under the road, with the station directly below Sheridan Blvd.

Challenge: The VE proposal is to leave Sheridan at its current location and build light rail on a bridge over the top of Sheridan, with the station on the west approach to Sheridan Blvd.

VE proposal has been modified to increase clearance over Sheridan to allow future CDOT roadway improvements. VE savings reduced from $10.5 M to $7.7 M.

Sheridan Station

$7.7 M funding shortfall for Sheridan$3.5 M from Park Mitigation Funds possible$4.2 M gap

Possibilities for Funding the Gap1.Money could be recouped from sale of the

property necessary to build Sheridan over2.Additional cost savings are being discussed

on bridge traffic control and construction methodology

Requires further discussion with stakeholders (Denver, CDOT) and the RTD Board

Sheridan Station

StatusMet with CDOT, Denver and Lakewood on April 30 to discuss Sheridan alternatives and funding options. Follow up meeting on May 14.

Sheridan Station

Auraria StationRTD, Denver and AHEC need further discussion on station location vis-à-vis overall Campus Master Plan

DecaturRTD and Denver are discussing relocating the station as part of a TOD opportunity. Discussions ongoing on cost implications. Possible private funding opportunity.

Auraria and Decatur

Value Engineering Status

The RTD Board will take action on 37 VE items on May 15. RTD will continue to work with the stakeholders on these remaining items. These items will go to the RTD board at the June 19 meeting.

•Single Track to Jeffco

•Changes to Drainage Plan
