1 To: From: Re: TIP Notification List George J. Scheuernstuhl, Director, Transportation Planning and Operations Administrative Modifications to the Transportation Improvement Program (December 2006) Date: December 19, 2006 Based on the Policy on Transportation Improvement Program Preparation, administrative modifications are reviewed and processed by staff with notification to various committee memberships and other interested parties. The administrative modifications listed below have been made and the TIP has been revised as of the date of this memorandum. Further details of these modifications are contained in the attached tables. Six modifications are needed for the cancellation of two projects and to return the funds to the CMAQ program, to fund two projects from the waiting list and move them into the CMAQ bike/ped pool, and to revise the CMAQ reserves. TIP ID# th Ave: York Street Bike/Ped. Crossing of UPRR This project will provide an ADA compliant at-grade bicycle and pedestrian crossing of the UPRR at 47th Ave. & York St. Safety will be enhanced through curb bulbouts and improvements at the railroad crossing. A trail will be provided along N. York Lane and N. York Street in vicinity of the crossing. At least 20 bicycle parking racks will be installed at the adjacent schools, recreational centers, and commercial districts. (Select project from waiting list for the CMAQ bike/ped pool, using CMAQ funds added to the TIP after receiving initial CDOT control totals. Added funds are $564,000 federal (CMAQ) and $242,000 local.) TIP ID# Closures Hampden Avenue: Monaco Street to I-25 Sidewalk Gap Construct continuous 10-foot wide sidewalk and pedestrian ramps on north and south side of Hampden Avenue (SH-285) from Monaco Street to I-25 to better serve pedestrian accessibility to the Southmoor Station on the T-REX light rail corridor. (Select project from waiting list for the CMAQ bike/pedestrian pool using CMAQ funds added to the TIP after receiving initial CDOT control tables. Added funds are $407,000 federal (CMAQ) and $174,000 local.)

2 TIP ID# CMAQ Reserves Currently unprogrammed, unallocated CMAQ funds. (Select projects for bike/ped pool funded with reserves. Decrease reserves by $726,000 federal and $181,000 local in FY2008.) TIP ID# CMAQ B/P Pool: TIP This is the master pool for CMAQ bicycle and pedestrian projects selected in the TIP process. Projects individually depicted are , ,, , , , , , , , , , , , (Select projects from waiting list using the CMAQ reserves and funds from cancelled projects. Add $245,000 CMAQ (from cancelled projects) and $105,000 local in FY2007. Add $726,000 CMAQ (from reserves) and $311,000 local in FY2008.) TIP ID# Arapahoe County: Upgrade Sanding Spreader Control Units This project will upgrade controls on 16 sander spreader units on tandem axle snowplow trucks, using a computerized hydraulic manifold attached to ground speed sensor modulated hydraulic motors. Arapahoe County will install automatic vehicle location devices (AVL) and GPS receivers in conjunction with the upgraded sander controllers. The upgrades create a programmable, precise delivery system that tracks and records distribution of material, and the application rate can be changed from the dispatch base. This project will be done through "advanced construction" (purchase) with local funds in FY05 and federal reimbursement with FY06 funds. (Cancel project at sponsor's request. Remove project from rollover list and return $75,000 CMAQ funds to CMAQ program.) TIP ID# IMC Consolidated Service Center: Natural Gas Fueling Station This project will install a Natural Gas fueling station at the Infrastructure Maintenance Center's Consolidated Service Center at 124th and Washington.

Administrative modifications by definition cannot affect the air quality conformity finding. Any proposed modification to the TIP that could affect the air quality conformity finding is classified as a policy amendment that requires further review and possibly analysis. As such, these modifications to the Transportation Improvement Program conform with the State Implementation Plan for Air Quality. The TIP Notification List includes the members of the Denver Regional Council of Government s (DRCOG) Regional Transportation Committee and Transportation Advisory Committee, TIP project sponsors, staffs of various federal and state agencies and other interested parties. The notification via is sent when administrative modifications have been made to the TIP.
