    PITKIN COUNTY ROAD MAINTENANCE AND MANGEMENT PLAN COUNTY ROADS AND RIGHT-OF-WAYS 2016 2 Public Works 76 Service Center Road Aspen, CO 81611 970-920-5390 Fax: 970-920-5374 www.pitkincounty.com PITKIN COUNTY ROAD MAINTENANCE AND MANGEMENT PLAN 2016 COUNTY COMMISIONERS: Michael Owsley Rachel Richards George Newman Patti Clapper Steve Child 3 PURPOSE STATEMENT The purpose of the Pitkin County Road Maintenance and Management Plan, hereinafter known as the RMMP, is to provide specific maintenance and management information to Pitkin County residents and to assist County Staff in prioritizing maintenance and setting expectations for County roads. The RMMP also establishes certain rules that have the force of law; violations of these rules are punishable as provided for herein and in the Colorado Revised Statutes, as they may be amended from time to time. DEFINITION OF A ROAD A Road as defined by Colorado Revised Statutes ([§42-1-102(85), C.R.S.]) "Roadway" means that portion of a highway improved, designed, or ordinarily used for vehicular travel, exclusive of the sidewalk, berm, or shoulder even though such sidewalk, berm, or shoulder is used by persons riding bicycles or other human-powered vehicles and exclusive of that portion of a highway designated for exclusive use as a bicycle path or reserved for the exclusive use of bicycles, human-powered vehicles, or pedestrians. In the event that a highway includes two or more separate roadways, "roadway" refers to any such roadway separately but not to all such roadways collectively. Pitkin County considers all appurtenances to roadways, such as parking, drainage structures, and snow storage areas to be part of the roadway.

  • All Grants Awarded Through Fiscal Year 2020 INTRODUCTION and KEY
    All Grants Awarded Through Fiscal Year 2020 INTRODUCTION AND KEY This report is a list of all grants awarded by the Colorado Historical Society’s State Historical Fund (SHF) since its inception in 1992 (state Fiscal Year 1993) through the end of Fiscal Year 2020. The amounts listed are the original award amounts. If for some reason the entire grant amount was not used (i.e. a project was terminated or was completed under budget) the full amount awarded will appear. In other instances grant awards were increased either to enable project completion or to cover the costs of easements. In these instances, the additional award amount is shown in a separate entry as an increase. In those cases where no work was accomplished and the funds were either declined by the grant recipient or were required to be returned to the SHF through rescissions, no entry will appear. For this reason, projects listed in one version of this report may not appear in later versions, and the financial information shown in this report may not be comparable to other revenue reports issued by the SHF. Grants listed in this report are identified by project ID number. The first two characters in the project ID number represent the fiscal year from which the grant was scheduled to be paid. The state is on a July 1 – June 30 fiscal year. So, for example, all grants made between July 1, 2006 and June 30, 2007 will be coded “07”. The next two characters identify the type of grant. In the case of grants that are awarded based on specific application due dates, the grant round in which the project was funded will be paired with either a letter or number.

But through innovative engineering, value pricing, public-private partnerships, and innovations in performance and manage- ment we can stop this dangerous downward spiral. The Galvin Mobility Project is a major new policy initiative that will significantly increase our urban mobility and help local officials move beyond business-as-usual transportation planning. Reason Foundation Reason Foundation’s mission is to advance a free society by developing, applying, and promoting libertarian principles, including individual liberty, free markets, and the rule of law.

  • Dallas High Five Interchange Honored As Public Works Project of the Year
    FOR IMMEDIATE RELEASE June 26, 2006 Contact: Becky Wickstrom Media Affairs Manager (202) 218-6736; 1401 K Street, NW, 11th Floor [email protected] Washington, DC 20005 Dallas High Five Interchange honored as Public Works Project of the Year Kansas City, Mo.—The Dallas High Five Interchange was recently named a Public Works Project of the Year by the American Public Works Association (APWA). The Texas Department of Transportation, managing agency, along with primary contractor Zachry Construction Corporation and primary consultant HNTB Corporation will be presented with the award during APWA’s International Public Works Congress and Exposition held in September in Kansas City, Mo. APWA Projects of the Year awards are presented annually to promote management and administration excellence of public works projects by recognizing alliances between managing agencies, contractors, consultants and their cooperative achievements. This year APWA selected 19 projects in five categories: Disaster or Emergency Construction/Repair, Environment, Historical Restoration/Preservation, Structures and Transportation. Awarded in the Transportation category, more than $100 million range, the Dallas High Five Interchange is the first five-level interchange in Dallas’ history. As tall as a 12-story building, the massive concrete structure is relieving a bottleneck that has strangled city traffic for years. The Interchange consists of just under 60 lane miles of new roadway (comparable to the width of the Dallas-Fort Worth Metroplex), stretching 3.4 miles east and west and 2.4 miles north and south (equivalent to about 100 New York City blocks). At the intersection of Interstate 635 (LBJ Freeway) and U.S. 75 (North Central Expressway), the interchange is designed to improve traffic flow, driving conditions and safety for more than 500,000 commuters each day.
