“It’s Not Easy Being Green… But It’s The Right Thing To Do” /td>

Low Impact Development (LID) is a new term for a comprehensive, sustainable land planning and engineering design that respects nature’s processes. The goal is to maintain and enhance the predevelopment hydrologic regime of urban and developing watersheds. This design approach incorporates strategic planning with site-scale management techniques to increase environmental protection, while allowing for development or infrastructure rehabilitation. This innovative approach can be used to help meet a wide range of Wet Weather Flow (WWF) control and community development goals.

Support for “Green Infrastructure” initiatives provides a new and exciting attitude to community development, infrastructure capacity, watershed restoration and protection. An announcement and Green Infrastructure Statement of Intent can be found at http://www.nacwa.org/earthday/. How communities can use this innovative and dynamic approach is highlighted in a document titled “Rooftops to Rivers”. It can be downloaded at http://www.nrdc.org/water/pollution/rooftops/contents.asp.

Let’s face it. Planners, developers and architects recognize that there is too much “impervious cover” — meaning too many parking lots, roads and roofs. Most consist of asphalt in the cityscape, commercial and residential surfaces, making runoff a serious problem and one to be dealt with. In many regions of the country, municipalities have created stormwater management utilities that impose a fee to property owners to remove stormwater based on the amount of impervious cover. In contrast, many municipalities are also offering financial incentives to landowners and developers who opt for newer infiltration methods to manage stormwater in lieu of the retention practices of the past and present.

For example, Elmhurst College in Darien, IL was recently awarded a $116,000 grant from the DuPage County Stormwater Management division to partially fund its innovative strategies for managing and monitoring water as part of a $23 million campus redevelopment project. The residence hall and surrounding site will feature the latest Best Management Practices (BMPs) for water management, which are integral to Elmhurst College’s plans to achieve LEED™ (Leadership in Energy and Environmental Design) status on this project (See Elmhurst College news release at Permeable Pavement Systems on our Web site).

The effectiveness of the techniques employed — as well as water quality — will be monitored with the help of Elmhurst College’s science faculty and its chemistry and biology students. From a cost standpoint, the BMPs are expected to deliver significant savings over the next several decades. For example, the paver material for the parking lot is manufactured to strength unmatched by asphalt paving and will not require major maintenance work (e.g., patching, seal coating, restripping or resurfacing), which is a costly expense over a 20- to 30-year period.

According to David Smith, Technical Director at the Interlocking Concrete Pavement Institute (ICPI), “The trend is clear. Municipalities are seeking new tools to decrease the public costs of handling drainage. Many of these tools can be implemented at the site scale by the private sector. These include rooftop and rain gardens, bioswales and permeable paving. These are low-cost, small-scale technologies. But taken together across a drainage basin, their benefits reduce private costs and the burden on city stormsewer and stream systems running at maximum capacity. When looking at all sustainable drainage technologies, the biggest opportunity for making an impact lies with permeable interlocking concrete pavement. It’s a natural, sustainable replacement for runoff and pollutant producing asphalt.

Choosing permeable interlocking concrete pavements, or PICP, is a viable solution — one that promotes infiltration. As zoning laws mandate more and more permeable pavements for driveways, parking lots and lowspeed roads, we have a combined responsibility to our industry to initiate and augment using pavingstones in permeable pavements. Let’s call it our “Action Coalition”.

Recent and upcoming initiatives open new windows of opportunity for those of us who are willing to seize the moment. We urge our distributors and their contractor-customers to join us in our commitment to Low Impact Development (LID) — a commitment that gained momentum five years ago and began even earlier. Cambridge first introduced our Turfstone product in 1995, long before permeable pavements were a hot button. More recently, we showed distributors and contractors how our Cobble III pavingstones could be adapted as a permeable pavement solution.

In 2006, Cambridge began producing Aqua-Bric® Type 1, a permeable interlocking pavingstone specifically designed for rapid removal of stormwater. In addition to key ecological benefits, the Aqua-Bric® Type 1 Permeable System offers remarkable aesthetic appeal, convenient access for maintenance and outstanding economic results on a 30-year life cycle cost analysis.

It’s not easy being green… but it is the right thing to do. The first step is awareness. The next step is education. Yes, the time is upon us to step up to the plate.

As we planned for the next season, all of us anticipated what economic indicators predicted — a soft market in 2007 for the entire building materials segment. To our surprise, while other producers up and down the east coast are experiencing a minimum drop of 20% in sales, Cambridge is actually maintaining sales levels equal to our 2006 marks. We can only believe this is largely attributed to our reputation for quality and our aggressive marketing posture.

However, because of our pre-season miscalculation of inventory, we are experiencing difficulties in meeting demands for many of our popular pavingstone shapes and colors. I appreciate your understanding and loyalty as we make every attempt to increase efficiencies under our present manufacturing capabilities — YOU WILL REMEMBER, WE DID NOT RUN OUT OF PRODUCT IN 2006.

Even under these unforeseen circumstances, my commitment to you and your contractor-customers has not wavered. Regardless of economic forecasts, our pavingstone and wall unit inventories at Cambridge will exceed any previous levels. This will be accomplished prior to December 31, 2007.

To further safeguard us against uncertain market conditions in the future, Cambridge is in the process of expanding equipment lines in our plants and increasing production personnel — most importantly in management positions — here at the Cambridge Center, in order to achieve greater output levels.

I will keep you apprised of our progress in upcoming editions of News & Views. Again, thank you for your understanding.

Our functional, ever-popular 4 x 8 Holland Without Spacer Bars and Chamfered Edges from The Crusader Collection is specifically designed to provide a finished look in a host of applications. For example, ideal uses include:

• Columns (see photo), stair risers and sides of stoops, steps, and landing overlays
• Facing on landscape, planter and knee walls
• As an alternative to clay brick (no chamfer) for pedestrian pavements
• Interior floors (see photo)
• Stacking pavers as you would bricks (Note: When using Holland without Spacer Bars & Chamfered Edges in a vertical application, seven pieces are needed per face foot with a 3/8” mortar joint)
• As a detail piece between the top of a MaytRx Wall and MaytRx Cap

Holland Without Spacer Bars & Chamfered Edges also provides a great way to transition the beauty of Cambridge Pavingstones with ArmorTec and a home’s existing, traditional clay brick face. Consider coordinating a Cambridge Pavingstones patio, walkway or driveway with the home’s architecture by using the pavingstone as a contrasting keystone feature above windows or for a water table detail.

Cambridge Holland Without Spacer Bars & Chamfered Edges measures 3 7/8” x 7 13/16” and 2 3/8” thick (same as our 4 x 8 Holland) and is made with ArmorTec mix technology. Available colors are Ruby, Onyx, Ruby/Onyx, Onyx/Natural, Chestnut/Salmon, Onyx/Chestnut, Golden/Onyx, Salmon/Onyx, Sahara/Chestnut, and Chestnut/Bronze.

With the exception of Ledgestone III Kits, which were introduced last year, Cambridge Design Kits have been important and also very popular products in the Cambridge line-up since our beginning. Ledgestone III, the newest, has already reached top billing in 2007. In this edition of Cambridge Campus, I would like to reintroduce all three Cambridge Design Kits to you along with some basic installation guidelines.

Simply put, when inserting perfect circle patterns into a field, our Circle Design Kits eliminate the need to make cuts. Available from the RoundTable and The Renaissance Collections, a kit, which consists of six distinctly different numbered shapes, will make an 8’ 5” diameter circle with eight rings. The pattern can be expanded by four more rings (9–12) by adding a second kit. For rings 11 and 12 using The RoundTable Collection, one band of 4 1/2 x 6 is required. Rings in excess of twelve can be added using the appropriate number of 4 1/2 x 6. To increase the circle with a kit from The Renaissance Collection, one band of 6 x 6 Cambridge Pavingstones is required. A placement diagram and additional information is provided with each kit.

Circle Design Kits are also useful in the creation of fan patterns. Minimal cutting is required (a placement diagram and cutting templates are available). Four fans (65” wide x 37” deep) consisting of a center pavingstone and six rings can be created from each kit.

Creating European-inspired random patterns is easy with our Random Design Kits. Also available from the RoundTable and The Renaissance Collections, each kit consists of four differentsized Cambridge Pavingstones. One kit will yield 113 square feet. Because Cambridge has done all of the planning for you, Random Design Kits contain the proper ratio of shapes to complete the pattern of your choice (13% of 3 x 6, 20% of 4 1/2 x 6, 27% of 6 x 6 and 40% of 6 x 9).

Shapes are alternated to install either of two patterns — Random Placement or Random Running Bond (see diagrams). When shapes are placed with staggered joints in a Running Bond pattern, a 1:1 ratio of pieces is achieved. Random Design Kits are available in solid and blended colors. Mix and match kits in complementing colors for even more variations in your “random design”.

Circle and Random Design Kits are available from The RoundTable Collection and tumbled-distressed from The Renaissance Collection. Shapes in both kits are 2 3/8” thick.

Natural clefts as found in bluestone give Ledgestone III its unique appeal. The 3-piece kit comprises the following shapes: 13 1/4” x 8 13/16” (50 pcs.), 8 13/16” x 8 13/16” (60 pcs.) and 8 13/16” x 4 3/8” (130 pcs.). Each 2 3/8” thick shape is a modular component of the 3-piece design, along the lines of Cambridge 4-piece Random Design Kits, but in a larger scale. We intended Ledgestone III to be laid in a random pattern as well, but in keeping with typical patterns found in bluestone or limestone installations where pavers meet at 3-way intersections (see diagram).

Ledgestone III is available from The Sherwood Collection and tumbled-distressed from The Renaissance Collection in a wide selection of colors. Both collections are made with our value-added ArmorTec.

Proper Handling: Ledgestone III has no chamfers. Handle with care when removing from the cube prior to installation. As a precaution against scuffing when compacting Cambridge Ledgestone III Pavingstones from The Sherwood Collection and also any shapes from The RoundTable Collection, a compactor with a bolt-on urethane protection mat should be used. As an alternative, place a heavy-duty geotextile (filter fabric) over the pavers prior to compaction. /td>
