April Project of the Month – Hogback Parking Lot


Wall Contractor: HTM Construction – Lakewood, Colorado

General Contractor: Kelly Trucking – Golden, Colorado

Owner: Colorado Department of Transportation – Golden, Colorado

Hogback Parking Lot located at I-70 and US 40

Our Project of the Month is the towering wall supporting the Hogback Parking Lot located at I-70 and US 40. Commonly known as “The Hogback”, it stands 40 feet tall and acts as a gateway to the mountains. Installed in 2006, the project had a number of requirements including durability, aesthetics and structural stability.

The design chosen was the Anchor™ Diamond Pro Stone Cut® 3-piece retaining wall system, designed and manufactured per the Colorado Department of Transportation (CDOT) specifications. “With our severe weather conditions, durability was a primary issue,” explained Martin Herbaugh of CDOT.

Aesthetics was also a key factor for choosing the Anchor™ Diamond Pro Stone Cut® retaining wall system. Rather than utilizing a traditional straight wall face, CDOT decided on the Stone Cut finish to simulate the rough texture of the area foothills. In addition, CDOT chose a
multiple face system, consisting of 18”, 11” and 7” wide face block. This broke up the “manufactured” look of typical single piece systems.

Size and texture of the block was not the only aesthetic concern. The area landscape is filled with a rich variety of colors and CDOT wished to utilize similar colors in a patterned array. The intent of the color variation was to compliment the colors within Dinosaur Ridge across the highway. Pavestone worked with CDOT on creating 4 custom colors comprised of multiple shades of Buff and Terra Cotta. The combined pattern and color variation broke up the sterile, commercial look and provided a visual appearance of depth and contour.

The rolling hills design was manually installed by HTM Construction Company and with their installation experience, they were able to achieve the same color variation seen within the surrounding landscape. With the combined teamwork from the design staff of CDOT, Pavestone staff and HTM Construction Company, CDOT’s architectural vision to create a retaining wall that mirrored the contours and colors of the land while not overrunning the surrounding landscapes was achieved. Overall, Martin stated Pavestone had exceeded his and CDOT’s expectations.

Pavestone’s ability to produce high quality, multi-piece retaining wall products in conjunction with the ability to create multi blended wall colors has Pavestone currently working with CDOT on another multi-face, multi-color wall at the Shaffer’s Crossing Project near Conifer.
