Marksheffel Road Improvements
The Marksheffel Road improvements were made on behalf of the Central Marksheffel Metropolitan District and El Paso County. Due to strong growth in the area and a lack of public funds, the Central Marksheffel Metropolitan District was established as a means to finance the much needed roadway improvements; primarily the updating of a rural two-lane roadway to a six-lane principal arterial.
Working with El Paso County and the City of Colorado Springs, Matrix Design Group developed design standards and typical sections for the roadway in-line with the intended criteria for the Marksheffel Road Corridor. Matrix personnel were responsible for the design, right-of-way surveys, and right-of-way acquisitions.
Additional improvements included the construction of two three-span bridges over the East Fork of Sand Creek and a storm drainage system sized to accommodate the future needs of the Marksheffel Corridor. These bridges now serve as major improvements for the roadway and have reduced the annual maintenance costs of the county by spanning Sand Creek and allowing for the 100-yr storm event. They also provide a grade separated crossing for the trail along Sand Creek designed to accommodate county maintenance vehicles.
Matrix also designed approximately 1.0 mi of channel improvements for Sand Creek, including a constant channel section of 120-ft, armored embankment slopes, eleven drop structures, and one checked structure. As part of the process, Matrix completed and received an Army Corps 404 permit, a FEMA CLOMR, and a floodplain permit from the Regional Floodplain Administrator.
The majority of Marksheffel’s original right-of-way was limited to sixty feet. Matrix was assigned the task of identifying all of the right-of-way needs and preparing the legal exhibits necessary for acquisition. Two major utilities, Kaneb Petroleum Pipeline and Mountain View Electric, presented challenging right-of-way and relocation issues. Matrix worked with both utility companies and El Paso County to establish designated easements in and outside of the proposed 210-ft right-of-way. Other utility coordination included Colorado Springs Utilities Gas and Electric Departments, 360 Networks, and Qwest.
