interlockutor INDUSTRY LEADERS REFLECT ON ICPI’S 20 YEARS AND LOOK AHEAD TO THE FUTURE

Back to the Future For the past 20 years, this magazine reported on new and innovative projects constructed with all types of David R. Smith segmental concrete paving products. In addition, it reports on new ICPI resources for design professionals and contractors. The magazine doesn’t spend much time discussing ICPI itself. While we take every opportunity to note in project articles when ICPI members were involved, we avoid touting ICPI’s events and accomplishments as an organization. Along somewhat different lines, we asked some ICPI members to reflect on ICPI’s 20th anniversary this year, briefly assessing the overall trajectory and value of the organization’s research, advocacy, and technical support of the industry. Looking back, they lend insight on ICPI’s past contributions and offer a glimpse of the future. DAVID QUINN, ASLA, SALES, ANGELUS BLOCK, LOS ANGELES, CA ICPI’s most successful effort has been the technical resources it provides. ICPI’s Tech Specs [technical bulletins] and research give engineers valuable information to specify products with confidence, in particular with PICP where engineers have been slow to embrace this new technology—the research validates ICPI’s design recommendations. Another major benefit that ICPI provides is access to industry people. There’s enormous advantage in talking with other ICPI members, finding out what trends they see and what’s been successful in their markets. DAVE HEIN, P. ENG., VP AND PRINCIPAL ENGINEER, APPLIED RESEARCH ASSOCIATES, TORONTO, ON We’re seeing stormwater management and environmental awareness as major trends. Sustainability is a big topic right now in all industries, and that makes it easy to talk about all the benefits that concrete pavers offer. Cities are beginning to see the differences between using asphalt and concrete versus using permeable pavers and they’re hearing about the success other cities have had with pavers. The performance with a surface like asphalt is affected by how it’s applied,

and that can be frustrating for city engineers. Also, you can’t test concrete or asphalt before you put it on a roadway the way you can with pavers. These factors add up to more awareness and higher usage. ED FIORONI, VP OF MARKETING, PAVESTONE, DALLAS, TX ICPI has been outstanding at providing technical support and standards that we all have to follow, which puts all manufacturers on equal footing. Another major contribution has been ICPI’s strong representation with government, to make sure that laws don’t impact the industry in a negative way. Also, the Institute has come up with some strong marketing ideas that manufacturers can use, especially in getting architects, engineers and city planners to listen to us. That’s helped to get a foothold in the commercial and municipal arenas. ICPI efforts are incredibly helpful for creating awareness and providing standards that advance the industry. I think we’re on the right track, with ICPI thinking strategically. CHUCK TAYLOR, COMMERCIAL HARDSCAPE ADVISOR, OLDCASTLE, DAYTON, OH I believe that this industry offers a great opportunity to build a future, not just for yourself but also for your family. In addition to making a living, and being in a solid industry that’s on a growth track, I’d tell anyone looking to follow in my footsteps to remember this is a field that can make you proud. When I started, my mission wasn’t just finding a career, I wanted to make a difference in the world and I feel like I’ve done that. I’m still doing that. I look forward to seeing the impact of the next generation. LARRY NICOLAI, SENIOR VP OF PAVERS BY IDEAL, WESTFORD, MA We need to continue to validate the long-term performance of concrete pavers, not only to the design community, but also to the larger buyer who may be thinking about industrial applications. To get more traction, we’ll need to continue to build our membership and keep investing in the type of research that allows us to offer facts supported through studies. We’re all working toward a future where interlocking concrete pavement can be seen as a first choice for projects. With the level of effort brought by ICPI and the commitment of those in the industry, we could get to that point. I believe the next 20 years will bring us all even more success. As ICPI drives forward into the next 20 years, it will be with two hands firmly on the steering wheel. We’re not interested in patting ourselves on the back while driving—that’s just dangerous. The future is here and a challenging road is ahead.

PERMEABLE PAVEMENT SOFTWARE UPGRADED Permeable Design Pro, a software application for hydrologic and structural design of permeable interlocking concrete pavement, now features CAD drawing output (see example drawing). Drawings are generated by the program after calculating the subbase thickness for water storage and subgrade infiltration, as well as the required subbase thickness to support anticipated traffic. The program automatically selects the thicker of the two subbase solutions and presents the CAD drawing from a menu selection. The drawing can include an underdrain, geotextile, and an impermeable liner if no infiltration into the soil subgrade is desired. The CAD drawing also specifies the height of the underdrain outlet, if the designer indicates this in the program, as a means to detain some water for infiltration. Also, the user can modify the CAD drawing by changing the subbase thickness and the underdrain pipe diameter, as well as the presence or absence of geotextile or an impermeable liner. The CAD drawing can be saved as a .dwg file for use in project drawings or submittals. Permeable Design Pro can be downloaded from www.permeabledesignpro.com for a 30-day free trial. The purchase price is $190 per license with a discounted price of $95 for design professionals and ICPI members.

Permeable Design Pro software now features CAD output of design solutions for permeable interlocking concrete pavement.

TECH SPECS UPDATE ICPI RELEASES NEW AND UPDATED TECHNICAL BULLETINS The Interlocking Concrete Pavement Institute (ICPI) released three new Tech Specs and updated another. The Tech Spec titles and content summary are provided below. All publications can be downloaded at www.icpi.org. ICPI has published its Tech Spec series of technical bulletins since 1995. Tech Spec 16: Achieving LEED Credits with Segmental Concrete Pavement consists of a complete rewrite covering how segmental concrete paving products can support earning credits under the latest version (v4) of the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) sustainable rating system for buildings. A summary of the changes are found in the article in this issue titled, “LEED Version 4 Supports Segmental Concrete Pavements.” The 20-page document presents excerpts from the LEED BD+C Reference Guide and comments on the role segmental concrete pavements can play in support of earning credits. Tech Spec 19: Design, Construction and Maintenance of Interlocking Concrete Pavement Crosswalks provides guidance on selecting and detailing assemblies based on anticipated traffic loads. The assembly choices are based on full-scale load testing and evaluation by the University of Waterloo, Ontario, Centre for Pavement and Transportation Technology. The eight-page bulletin covers assemblies using aggregate, stabilized and concrete bases using sand and bitumen-sand setting beds for the concrete pavers. Specify interlocking concrete pavement crosswalks, bases and edge restraints with more reliable performance. Tech Spec 20: Construction of Bituminous-Sand Set Interlocking Concrete Pavement provides a well-illustrated and thorough description on how to construct this durable system for sidewalks, crosswalks,

intersections and streets. The eight-page bulletin outlines the tools, materials and steps for bitumen-set concrete pavers on a concrete base. This application is essential in high traffic, urban areas subject to buses and trucks. The text is aimed at contractors while presenting a procedure of high interest to civil engineers, landscape architects and architects. The bulletin accompanies ICPI’s guide specifications and detail drawing on bitumen-set applications. Tech Spec 21: Capping and Compressive Strength Testing Procedures for Concrete Pavers informs paver manufacturers, paver testing laboratories and specifiers on recent sweeping changes to the compressive strength testing in ASTM C140: Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units. The eight-page bulletin provides step-by-step cutting and refined capping procedures for crushing paver specimens using flow charts and photos to help testing labs produce consistent compressive strength test results. The bottom line on the changes to ASTM C140 is it now adjusts compressive strength results from concrete pavers with different thicknesses, thereby eliminating the confusion resulting from lower strengths from thicker pavers.

ST. LOUIS MAKES SUSTAINABLE STRIDES WITH DOZENS OF PERMEABLE PAVER PROJECTS

he Midwest is no stranger to the use of interlocking concrete and permeable pavement solutions for many private, commercial, municipal and educational projects. In particular, municipalities with rivers that overflow seasonally and those receiving polluted stormwater are increasingly deploying permeable interlocking concrete pavements (PICP) for their projects and enjoying the benefits.

InterlockDesign.org

Over 23,000 sf of pavers were mechanically installed for the main access road and over 3,000 sf of pavers were hand-installed for pedestrian/sidewalk areas after the roadway was completed.

In St. Louis, the challenges of an aging combined sewer system and new stormwater requirements mandated in 2006 by the City’s Metropolitan Sewer District (MSD) led to the implementation of PICP in alleys, parking lots, sidewalks, trailheads and many other applications. Multiple projects including a series of green alleys constructed since the MSD mandate demonstrated concrete pavers as a trusted solution for many City initiatives, as well as for private projects. While often used to reduce stormwater pollution, the successful performance and aesthetic appeal of concrete pavers in projects across the city has led to their popularity and continued use. ECO-INSTALLATION: LEWIS AND CLARK COMMUNITY COLLEGE – NATIONAL GREAT RIVERS RESEARCH AND EDUCATION CENTER At the National Great Rivers Research and Education Center at Lewis and Clark Community College in East Alton, IL, it’s all about green. Established to lead research, education and outreach related to the interconnectedness of large rivers and their communities, being “green” was nonnegotiable for the center’s construction. The first of two phases of construction began in 2008 with a field center to drive research and serve as a home base for educational programs. The project secured a total of $6.8 million in construction funding with an additional $16.3 million designated by former Illinois Governor Pat Quinn. From the project’s inception, the goal was obtaining the highest Leadership in Energy and Environmental Design (LEED) certification. LEED credit-earning components for this project include: sustainable heating and cooling systems; a detention basin for stormwater quality control; plus permeable interlocking concrete pavement, as well as other pervious pavement systems. The paver portion of the project includes a plaza, sidewalk and main access road totaling more than 25,000 sf of manually and machine-placed pavers, installed in less than one week’s time. Speed of installation was a factor in the project’s success because it quickly opened the

roadway (unlike other pavement options that require downtime while curing), thus enabling multiple construction efforts to occur simultaneously. “The facility is a showplace for green building that incorporates multiple types of green paving systems,” says Dave Godar, P.E. for Sheppard, Morgan & Schwaab, Inc. Material reuse was accomplished by using fly ash in the cast-in-place concrete and in the modified soil road base. Also, the project had to consider the historic flood levels from the nearby Mississippi river. “We didn’t want permeable pavement where the flood level is, because it could clog,” Mr. Godar says. The sidewalk portion of the project covers about 875 square yards; another 2,500 square yards makes up the roadway. The system uses 3-1/8 in. thick concrete pavers, 2 in. of bedding aggregate, 4 in. of open-graded aggregate base and 12 in. of larger aggregate subbase over filter fabric or geotextile. “There are two schools of thought about using filter fabric,” Mr. Godar says. “Some say that over time the filter fabric can become clogged and prevent the rainwater from soaking into the ground. This site had sand material as the subgrade. We opted to go with filter fabric to prevent the underlying sand material from migrating up into the voids of the subbase aggregate, which could cause settlement of the pavers.” To reduce labor costs, project design included machine installation for the interior pavers. “It was all kind of new,” Mr. Godar says of the plans created in 2009. “We hadn’t done anything like this before, although there were some examples out there.” Funding for the project included some federal highway money, which meant all approvals had to go through the Illinois Department of Transportation (IDOT). Because many of the components were not standard and were not covered by IDOT specifications, some of the materials were considered experimental. The project took most of the 2010 construction season to complete. “The idea was for this to be a showplace,” Mr. Godar says. “It is open to the public, so if we had clients

who wanted something similar, we could point them to the National Great Rivers Research and Education Center.” HEALTH APPEAL: RANKEN JORDAN PEDIATRIC BRIDGE HOSPITAL At Ranken Jordan Pediatric Bridge Hospital, about 15 miles northwest of St. Louis, permeable pavers satisfied the hospital’s stormwater requirements, providing an overall healthy feel to the campus. Coined a “bridge” hospital, the facility staff works to help children transition between hospital and home. With a history of expansion and growth, the hospital was built in 1941 as the Ranken-Jordan Home for Convalescent Crippled Children. In the 1960s, it expanded to accommodate more patients and staff, and in 2002, moved to a new 62,000 sf, 34-bed facility in Maryland Heights, MO. Several years later, the facility required more parking for patients and visitors. When the organization first looked into expanding its parking capacity in 2009, stormwater requirements came into play immediately. The facility includes bio-retention basins and rain gardens. PICP met the MSD’s stormwater reduction requirements. “At the time it was fairly cutting edge,” says Ted Spaid, co-founding principal of SWT Design, based in St. Louis, which led design for the project. “The MSD had just started enacting water quality management regulations for the region.” Rather than using underground stormwater tanks and other solutions, the design team decided on PICP to meet the requirements. The first of Mr. Spaid’s projects with PICP took place at SWT’s office as an early test run right when the pavers first became available. Having successfully worked with them, SWT decided to use them in the hospital project. The pavers were manually installed between September and October of 2009, but required some special design attention because the parking lot presented a challenge with its radial layout. The designers addressed this by taking advantage of the paver pattern. The contractor installed the entire parking lot in a herringbone pattern, which can accommodate radial layouts, and saw cut the edge pavers to fit the non-uniform shape. Another unique design element used pavers in contrasting colors to designate parking stalls rather than paint lines on the pavement. “The installation itself was a month-long process,” Mr. Spaid says. But the outcome was several-fold, for the 20,980-sf installation. First, it satisfied required municipal green elements by draining to rain gardens to help with biofiltration. And while there was additional expense due to the paving materials, the aesthetic appeal was a positive payback. “Many clients are timid about wanting to spend the extra money on permeable pavers, but then they realize it delivers more than stormwater management. If you can turn stormwater management into a positive aesthetic attribute, it’s much nicer. There are multiple layers of savings by using the pavers correctly and strategically.” For example, the parking lot design allowed for surface runoff to sheet-flow over the asphalt and infiltrate into the permeable pavers. Eventually, that water would go to a centrally located rain garden or bio-retention area, and would flow to a larger detention basin as needed to prevent down-

stream flooding. “This design replaced the need for typical drainage structures and piping system that you would find throughout a parking lot,” Mr. Spaid says. “Based on a cost-benefit analysis, a traditional stormwater infrastructure design was comparable to the cost of the permeable paving system. Furthermore, the permeable pavers provided the required stormwater management to decrease the flow of runoff and help control sediment.” The pavers and rain garden also decreased the size of the necessary detention basin and preserved land for future expansion. The project is maintained with annual vacuuming and regular cleaning. MSD requires an annual inspection report that includes dates of inspections and cleaning methodology. Additionally, the report must confirm that all stormwater structures are functioning and that watersheds have not been disrupted by pavement clogging or erosion. The report must demonstrate that all best management practices (BMPs) and landscapes are functioning as designed. In a care setting, particularly one focused on children, the sub-story is aligning construction materials with quality and

health, Mr. Spaid says. “It’s a healthy living story,” he says. “Here we are at a pediatric care facility and we want to show quality care for children. Through stormwater management and rain gardens, there’s a story to be told about water quality and creating an environment not only contributing to a healthy planet, but to human well-being and aesthetics.” TRAILHEAD SERIES: GREAT RIVERS GREENWAYS Concrete pavers may be “green,” but they’re not often found in the woods. The Great Rivers Greenway (GRG) District is an exception. The network spans more than 100 miles of trails and greenways among 1,400 acres through St. Louis City, St. Louis County and St. Charles County that support hiking, biking, walking and other outdoor activities. Established in 2000, the GRG initiative set out to improve health, reduce pollution and stabilize communities, among its many goals. That’s where PICP comes in. In 2006, the organization extended one of its trails, which involved installing two new trailheads. Given the stormwater restrictions then recently passed by the MSD, the Great Rivers Greenway project managers and designers crafted a proposal for PICP as the surface for the new sites. A handful of other trailheads and parking areas built in the following years also realized the benefits from PICP. “We considered leaving it asphalt,” recalls Carey Bundy, project manager for GRG. “It would be cheaper on the front end,” she says, “but PICP would count toward water quality credits.

The South County Riverfront Access and Trail features extensive use of a variety of pavers including approximately 15,000 sf of weathered ashlar-pattern pavers and nearly 14,000 sf of permeable interlocking concrete pavement in the parking lot shown here.

We went with pavers mainly because if something did go wrong later, they are much easier to get into and work on.” Because it spans the city and two counties, funding for GRG projects comes from various sources, including tax dollars and federal grants. GRG resources are used to build and improve the trail network and then projects are turned over to the municipalities for maintenance. Working with pavers required a lot of testing, partnerships on design elements and determining performance requirements that would satisfy the mission of the trails. The installations were not easy. “The most challenging part is the location and site accessibility,” says Scott Rozier, president of St. Louis-based Rosch Company. “The trails go through the middle of the woods, or across old abandoned tracks, and it’s very challenging logistically to get the subbase installed and place everything where it needs to be.” In spite of the challenges, GRG found that the PICP systems with additional green elements such as plantable walls and reclaimed water systems have performed well. So well in fact, more projects are in the design and planning stages as a result. “Initially, people said they wanted to go with the traditional route and didn’t want to try this new but different material,” Ms. Bundy says. “But it’s on the ground now in a lot of places. Getting a pilot installed so people can see what it is, that is very helpful.” 

EARLY ADOPTERS

Taking cues from the successes of projects in cities like Chicago, St. Louis has installed several green alley projects since 2007 utilizing permeable pavers and interlocking concrete pavement. In 2009, the City of St. Louis commissioned a Pilot Green Alley project using donated materials and labor. Three alleys were installed that year with pervious concrete, porous asphalt and PICP. The performance of the city-owned alleys is being evaluated over time. All of these are built over open-graded aggregate reservoirs allowing stormwater to drain through the system per the City’s specifications. Green alleys are not unique to St. Louis, but the city’s history and layout with centuries-old alleyways and roads lends to more paver installations in the future, says John Grimm, of the Metropolitan Sewer District. “There are some suburbs that have alley arrangements, but they are not as prevalent,” he says. “It’s mainly particular to the city.”

DESCRIPTION: The client’s main goal for this project was to pay homage to the 146-acre forested land by incorporating “natural” (stone) products. The project’s objectives: create pleasant walkways (some had to be ADA compliant); increase parking space; and improve drainage. The natural stone retaining walls and paver driveway sweep drainage from the hillside by directing water away from the two upper buildings. Cutting through and down two hillsides increased parking stalls from 4 to 15 using 2,000 sf of concrete with natural stone parking stripes. Dry- and wetlaid walkways of approximately 3,500 sf were installed and multiple retaining walls were built or restored.

kitchen with seating inside and outside the pool. The project also includes a 20-ft double waterfall, three built-in bistro tables, a 20-ft high boulder wall system featuring perennial garden plants and floating boulders built into the pool. Trenching was so extensive under and around the hardscape areas that 1,500 cubic yards of soil had to be removed and replaced with compacted clean stone so there was no threat of future settlement.

concrete pavers, clay pavers and a rotting cedar tie wall. The plan included a water/fire feature flowing into the pool, a grill/bar island, stone fireplace and a fire boulder. Planters were cut into the walls to create character and soften the hardscape, and a flowing inlay design connected the patio nook area to the pool deck. A sealer was used to differentiate colors for the inlay. LED uplights highlight the walls and fire features.

PERMEABLE PARADISE  LOCATION: Grand Island, NE  SIZE: 4,300 SF  INSTALLER: Grindstone Hardscapes  PRODUCTS: Belgard  DESIGNER: Grindstone Team

DESCRIPTION The goal of this new driveway, patio and front entrance project was to create a maintenance-free system with extreme curb appeal. The entire project is permeable

and heated to melt snow. The paver field was laid at a 45-degree angle to the house, a solution to the challenge of the road not being square to any entrance on the driveway or walk. Snow and sleet drain through the joints upon touching the heated paver surface. The heat tapes were fastened to wire mesh on top of the rock base to hold it in place, and then the bedding layer was screeded over it.

visual experience. The contractor designed one-of-a-kind patios, walls and planting areas utilizing concrete paver circle kits. Among many challenges was how to continue the arc of the varying circles’ sizes through the connecting pathways. To accomplish this, the contractor installed only curvilinear courses of pavers that appear to run off the pathways and rejoin later. In total, 14 paver circle kits were used and approximately 3,600 sf of pavement.

within the overall project and include a partially covered outdoor kitchen/bar, large dining area, covered pavilion and fireplace patio, in-ground swimming pool with accompanying pool deck and a raised gas fire pit patio bordered by a curved seat wall. Large pavers were chosen to fit the grand scale and style of the project, but also create a smooth surface along the pool deck.

LEED v4 Review NEW VERSION MAINTAINS CONTINUED SUPPORT FOR SEGMENTAL CONCRETE PAVEMENTS

Released in November 2013, LEED v4 continues support of segmental concrete paving products to earn credits toward certification as a sustainable project. There are, however, some significant changes under familiar credit categories. The table below lists credit categories and credits that can be supported by using segmental concrete paving products. Detailed information can be found in ICPI Tech Spec 16: Achieving LEED Credits with Segmental Concrete Pavement available at www.icpi.org. LEED v4 POTENTIAL POINTS FROM SEGMENTAL CONCRETE PAVEMENTS:

CREDIT CATEGORY: SUSTAINABLE SITES Credit: Open Space This credit recognizes designs that use open space to encourage interaction with the environment and other people, as well as passive recreation and physical activities. Segmental concrete pavements can be utilized in the design of such spaces. Credit: Rainwater Management Gone are separate points earned for stormwater management quality and quantity. Pollution and volume reduction are now combined into one credit. Credits are earned based on management of the 95th or 98th percentile rain event, or by matching pre-development conditions. Management means on-site detention and/or infiltration, which virtually requires the use of permeable pavements such as permeable interlocking concrete pavements (PICP). Credit: Urban Heat Island Requirements continue for roof surfaces having minimum solar reflectance indices (SRI). The minimums have been increased from 29 to 39 and a three-year (aged) minimum of 32 for low-sloped roofs. For non-roof surfaces, minimum requirements for reflectance have changed from an SRI method to a solar reflectance (SR) measurement method based on using a different ASTM test method than that for SRI. SR measures outbound (reflected) radiation divided by inbound radiation, both measured at four specific wavelengths. The initial SR required is 0.33 with a three-year aged minimum of 0.28. This means that SR (as well as SRI) requirements benefit the use of lighter paver colors. Concrete grid pavements continue receiving points so this benefit essentially remains unchanged. The grids need to be at least 50 percent “unbound,” meaning turf grass or light-colored aggregates.

Credit: Water Efficiency Capturing and reusing runoff for irrigation with PICP or other means no longer earns points. LEED v4 makes this condition a project prerequisite to qualify for participation in their program. If the project has no landscaping, then this requirement is not applied. CREDIT CATEGORY: MATERIALS AND RESOURCES (MR) The MR structure has a four-pronged approach: life-cycle assessment; toxic chemical avoidance; building reuse; and waste management. This credit category is restructured to address a more holistic, life-cycle view of creation, use and disposal of construction materials, rather than just recognizing recycling as in previous LEED versions. Here are the credits relevant to the concrete paver industry: Credit: Building Product Disclosure and Optimization— Environmental Product Declarations (EPDs) This new credit requires EPDs to be supplied on at least 20 different products in a project and to be cradle-to-gate impact assessments for various pollutants, including carbon emissions and energy use. EPDs can be paver-industry averages typically reported by an association or product-specific EPD reported by a paving product manufacturer. Credit: Building Product Disclosure and Optimization— Sourcing of Raw Materials Multiple criteria from LEED 2009 credits have been combined into this credit. Some old criteria are folded into other MR credits, such as Building Life-Cycle Impact Reduction and Building Product Disclosure and Optimization—Environmental Product Declarations. Here are the options under this credit heading:

 MR Credit Resource Reuse: Materials reused on-site are no longer required to be repurposed.

 MR Credit Recycled Content: The requirements for recycled content have not changed; however, this criterion is now combined with other criteria in a single option.

 MR Credit Regional Materials: The

500-mile (800 km) radius requirement was decreased to 100 miles (160 km). The definition of regional has been expanded to include the distribution and purchase location, and now includes all points of manufacture.

Credit: Building Product Disclosure and Optimization– Material Ingredients This is a new credit with three options for earning points:

 Material ingredient reporting: Paver manufacturer reporting of ingredients, reporting via health product declaration or cradle-tocradle certification.

 Material ingredient optimization: Manufacturers undergo a “green screen” assessment, a more rigorous cradle-to-gate certification, or certify that products have no substances of “very high concern” according to the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) program published by the European Union.

 Product manufacturer supply chain optimization: Supply chain providers to a concrete paver manufacturer meet certain criteria for environmental, health and safety protection. Credit: Construction and Demolition Waste Management This has changed from LEED 2009. Reuse of segmental concrete paving products can be part of a demolition/ reuse plan if the paving products are reused or recycled. This is achieved through either 50 or 75 percent diversion of project waste from a landfill. A third option sets a limit on the pounds (2.5) of waste generated per sf of building floor area.

LEED v4 continues credits and points issuance for innovation in projects and credits for participation of a LEED AP in a project who specializes in particular credit areas. In addition, credits can be earned for “regional priorities.” For example, if groundwater aquifer recharge is a regional priority, then points could be earned by using PICP. 
