• One of the advantages of a digital publication: page count isn’t constrained by a printing budget or the signature because there is no printing. For readers distant from the printing process, a signature is a group of pages “printed on both sides of a single sheet of paper that once folded, trimmed, bound and cut, become a specific number of pages depending on the page size

and the size of the press sheet” (from www.designersinsights.com). No paper = no signature. The digital advantage in this issue is manifested in wider coverage of the Hardscape North America Project Awards. Expanded reporting covers the concrete paver winners and projects using a combination of hardscaping products. Previous printed magazine issues only featured concrete paver winners. The result is about twice as many pictures and text compared to those in the previous ten years’ coverage on this national contest. Congratulations goes to the winners and honorable mentions! We hope you enjoy viewing these top-notch projects. In addition to the awards, this issue features two beer breweries using permeable interlocking concrete pavement (PICP), one in North Carolina and the other in Wisconsin. In both cases, runoff reduction was required by the municipality and/or state government. The permeable pavement in

North Carolina enabled water reuse for irrigation. The site in Wisconsin prevented stormwater from overloading a combined sanitary and stormwater sewer system, thereby saving wastewater treatment costs and reducing the risk of sewer overflows. PICP use is often dictated by local stormwater reduction ordinances. However, there is a growing project portfolio by private developers who have taken advantage of cost savings from PICP’s dual role of stormwater management and pavement. ICPI recently held a webinar demonstrating how to justify PICP from an economic analysis. The key is identifying on- and off-site benefits to include in a life-cycle cost analysis (LCCA). Those lifetime costs can justify using PICP rather than conventional stormwater management practices that manage runoff from impervious pavements and roofs. The most effective economic justification for using PICP emerge from developable land made available from reduction or elimination of detention ponds. Another area where PICP yields significant economic benefits is reduction of flows (due to infiltration) to waste treatment plants that process combined sanitary and stormwater sewage. A detailed LCCA example with these aspects was presented in a recent ICPI webinar that introduces a PICP LCCA Excel tool. The tool is available upon request to ICPI members and design professionals via dsmith@icpi.org. If readers are interested in viewing the recorded webinar, it’s available for $50. ICPI voting members can access the webinar for $30, affiliate members pay $35, and informational members $40.

RAIN AND DRAINAGE MANAGEMENT Not something common to pools, permeable interlocking concrete pavement appears like the local limestone and matches the adjacent new buildings. Motivation to use a permeable design likely came from the City of Austin providing 100% pervious cover credit for the pool deck. The surface effectively allows infiltration through the pavement section while not destabilizing the soil subgrade around the pool structure.

National Brewery Relies on Permeable Pavers to Demonstrate Corporate Values

“Bigger than Beer” is a message shared in all of Sierra Nevada Brewing Company’s communications. That message highlights the company’s commitment to sustainability and environmental responsibility in all areas of its business. First starting in 1980 in Chico, California, the brewery expanded in 2014 to Mills River, North Carolina. That facility became the first production brewery in the U.S. to be certified LEED® Platinum, the highest level awarded by the most widely used

green building rating system in the world. One of many design and construction components contributing to LEED® certification

PROJECT CREDITS heat island effect. However, PICP for the parking lot and non-permeable pavers for sidewalks and patios fulfilled another design goal the owner wanted, says Glenn Walters, principal of Design Workshop in Asheville, NC. “The owner wanted the facility to be a special place that showcased the company and its commitment to environmental responsibility,” he says. “Because the parking lot serves as an entry plaza to the brewery, pavers provide the aesthetic quality that welcomes visitors to a quality, great brewery.” “The brewery sits on the French Broad River, which provides 90% of the water used at the facility. So, the use of permeable pavers for the 2.58 acres of employee and guest

parking captures and cleans the water before it returns to the river. This clearly demonstrates environmental responsibility,” says Brian Wierman, chief operating officer of Rivertop Contracting Inc., the landscape contractor for the project. Concrete pavers chosen for the project and supplied by an ICPI member were machine-placed, 3 1/8-in thick units set in a herringbone pattern. They rested on a 2-in thick bed of ASTM No. 8 stone over a 4-in thick base of ASTM No. 57 stone. The subbase reservoir comprised of 6 inches of ASTM No. 2 stone over geotextile. The water infiltrating into the permeable pavement is handled one of two ways. The pavement structure directs water

release the stormwater according to state requirements, says Walters. The design for the expansive pavement included parking space striping and crosswalk designations with colored pavers, and crews had to install pavers around landscape islands scattered throughout the area. “A lot of pre-construction planning was necessary to make sure everything was lined up properly as we laid the pavers,” says Greg Ambrose, vice president of United Hardscapes and ICPI member, the contractor who installed the pavers. “One key thing that we did was hire a surveyor to create a 25-ft by 25-ft grid over the entire site so

we could pave from point to point in the stone the next day—which and be sure that everything lined up meant re-doing the work,” he says. properly.” While the need for coordination among different crews is not The size and location of the uncommon in a large construction parking lot presented other site, it is important to address it in challenges not related to the pre-construction meetings that installation of the pavers, points address everyone’s plans for staging out Mr. Ambrose.

into the parking lot, some of the design was necessary to protect the permeable paver area, says Mr. Wierman. “The design architect’s team addressed this with wide concrete edging that kept pea gravel in walkways from entering the permeable pavers in the parking lot.” In addition to the project size and the congested worksite, rain proved to be an obstacle with 85 inches failing in the area during construction, twice the annual average. While there was rain, there was no snow to prevent work from continuing, and Mr. Ambrose notes that his installation crew worked in all four seasons. He used his Ohio-based crew for the North Carolina project because they had the needed job skills. “We mobilized five different times over the course of construction, with crews in place for four weeks and two weeks at a time, depending on the work scheduled.” Although the project size, a busy construction site, and coordinating material staging plus too much rain, the project was completed in time for the August 2014 opening celebration event. “The entire site demonstrates Sierra Nevada’s commitment to the environment,” says Mr. Wierman. “Permeable pavers played an important role in the overall program to reclaim water that also includes rooftop design, rain gardens, and collection tanks that capture water to re-use for irrigation.” l

The old saying gets confirmed again: The three most important things in real estate are location, location, and location. Success in commercial development starts there, then moves to renovating a building to create a welcoming environment that appeals to tenants’ customers. When the owners of Dead Bird Brewing, a local craft beer brewery, initially saw the site of their first brewery and taproom, they were attracted to the vintage appearance of a 130-year-old building that housed a grocery and delivery service, as well as a book bindery.

permeable pavement that could attract a number of tenants and their customers. “I have used interlocking concrete pavers for a parking lot on a previous property, so I know how they improve the appearance of a commercial property,” says Mike Grinker, president of Sid Grinker Restoration. “We wanted a cobblestone appearance for the parking lot so we used three different shapes and sizes with an accent color paver. The pattern eliminated the long, straight joints typically associated with pavers and

PROJECT CREDITS gave us a look that compliments the building.” With a craft brewery attracting younger customers, concrete pavers were the perfect material for the parking lot, says Carrie Bristoll-Groll, PE, CFM, Principal Civil Engineer/CEO of Stormwater Solutions Engineering. “Millennials are eco-sensitive and want to see more than a boring concrete lot that doesn’t support environmentally sustainable efforts,” she points out. Permeable pavers and bioswales eliminated stormwater from entering the combined sewer system. They enabled an environmentally-responsible design, but are also more attractive, she says. The 9,000-sf parking lot was paved with 3 1/8-in thick permeable interlocking concrete pavers supplied by an ICPI member. “There were different pieces in the pattern—a square, a rectangle, and a larger

rectangle—to produce the design,” says Jason Steadman, estimator with Trees on the Move, the pavement installation contractor. The pavement was laid by machine, but the color of the pavers and the design of the pavers give it a hand-laid look, he says. The jointing and bedding course stone were ASTM No. 8 aggregates over a 3-in thick base course of ASTM #57 stone. A 15-in thick subbase reservoir consisted of No. 2 stone, points out Mr. Steadman. “We did not use an impermeable membrane under the subbase so that water can infiltrate into the soil, which is 60–70% clay. We placed a geotextile on the soil to separate it from the subbase.” Although the permeable parking lot should be able to store and infiltrate most rain or snowmelt, the pavement can handle excessive amounts of water by draining it into

Although the cost of a permeable paver for a large parking lot is more than traditional concrete or asphalt, a grant from the Milwaukee Metropolitan Sewerage District helped offset some of the costs of green infrastructure installation says Mr. Grinker. The combination of the grant funds to reduce contribution to a combined sanitary and storm sewer system, and more intangible visual and safety benefits helped justify the additional expense, he adds. In addition to the parking lot, Mr. Grinker also used pavers for an adjacent property. A patio

and walkways that tie together the commercial and residential properties were constructed with permeable pavers for a variety of reasons.
