| 2003 ASLA Annual
Meeting & EXPO
October 30 - November 3, 2003 New Orleans, Louisiana EXHIBITOR MINI-SHOPS **NEW** Friday, October 31 See How the Garsy Garden Systems Work One of the most common design challenges is to achieve height—and therefore impact—with young plants instantly. GARSY® Garden Systems has engineered a new and patented planter concept for “instant landscaping “ in this third dimension. Suitable for hedging (topiary look), seedlings (colour), foliage, herbs, ground covers, and climbers, this durable and galvanized system is solving problems for landscape architects, designers, urban planners, property developers, and municipalities. The GARSY® planters require no excavation, are easily transportable (even when fully planted) and maintenance-friendly, offer optimum plant growing conditions, and are ideal for roof-top gardens, shopping malls, streetscapes, commercial landscaping, and upscale residential applications. GARSY® products are currently being used in 19 countries worldwide, including the USA and Japan. For more information, please contact www.garsy.com or visit Booth #1434. Surface Drainage This session will cover why surface drainage is important; the various options for surface drainage; and the critical factors to consider in product selection and project design. The technical emphasis will primarily be on loadings and hydraulics, both critical to the overall design and lifetime of the site. Selecting the correct load rating helps to prevent product and unsightly pavement failures. There are numerous standards for loadings and this session will explain some of the differences between current standards and the key factors to consider when selecting a load requirement. Hydraulics determines the right size and quantity of product to fulfill the drainage requirement. Correct calculation prevents excessive product usage or flooding due to insufficient drainage. The session will cover factors affecting hydraulics and the options for how hydraulic performance is currently calculated. For more information, please contact www.acousa.com or visit Booth #426. Biobarrier: The Ultimate Root Control System The Biobarrier® Root Control System is a unique method of preventing tree roots from disrupting hardscapes. Placed vertically in a trench between a tree and the areas that you wish to protect, Biobarrier works invisibly to redirect tree roots. A 15-year success record permits the company to confidently guarantee Biobarrier for a minimum of 15 years. The delivery system for Biobarrier is Typar®, a standard AASHTO polypropylene, geotextile, drainage fabric. Typar is permeable so water, air, and nutrients can easily pass through without disrupting soil hydrology or causing drainage problems. Permanently attached to the geotextile fabric are polyethylene nodules impregnated with trifluralin, a pre-emergence herbicide with a proven 45-year history. The Biobarrier nodules containing trifluralin are engineered to slowly release the herbicide, creating a narrow vapor zone. It is this zone that causes roots entering it to swell, preventing cell division and further elongation in that direction. New roots outside the zone are unaffected and continue to grow normally. Trifluralin is not systemic so there is no harm to the tree. Biobarrier is easy to cut and install, even around irregular objects and contoured areas, and surface grade level positioning insures it will not be a tripping hazard. Biobarrier is manufactured in Old Hickory, Tennessee, by BBA Materials Technology Group. For more information, visit Booth #404. Introduction to Glass Fiber-Optic Lighting Technology: Benefits
and Uses for Exteriors and Landscape Design Sandra Liotus Lighting Design, LLC (SLLD) is a unique, custom, turnkey lighting design firm. All lighting systems are custom designed and built specifically for each project. Glass fiber-optic lighting technology will be introduced and demonstrated. Three basic engineered components make up a glass fiber-optic lighting system: a remotely positioned submersible 150-watt metal halide light source; a glass fiber-optic harness which is comprised of a multitude of tails, which allow heat, electricity, and UV-free illumination to travel through highly flexible tubing; and custom designed miniature output fittings, all made from solid metals to suit the specific environment and fitted with ground glass lenses. SLLD will demonstrate how all lensed fittings can be focused from a very tight spot of light to a full wash of light and will explain how the systems have been successfully used for landscape environments, gardens, monuments, and building facades. For more information, please contact s.liotus@worldnet.att.net or visit Booth #1547. Building Spray Parks Make parks fun again! Kids have always taken to backyard sprinklers, neighborhood fire hydrants, and city fountains to cool off. Kids love water. The trick is how to let them play with water safely. The answer for many communities across North America is spray parks. Featuring bright colors, themed fabrications, and crazy geometric shapes, spray parks turn flat concrete slabs into three-dimensional water worlds. Nothing brings smiles to a park like an exciting world of shapes and showers. Spray parks (also known as splashpads) are fun and exciting new alternatives to community recreation areas, day cares, schools, aquatic facilities, or resorts. The purpose of the session is to inform landscape architects, municipal officials, developers, planners, and other community members of the benefits of developing spray parks. The session will cover a wide range of important issues including: benefits of spray parks; site considerations; realistic budgets; supplier selection; and construction practices. For more information, please contact www.waterplay.com or visit Booth #1642. “Or Equal, Or Else” The Landscape Architect’s
Responsibility in the Selection of "or equal" Products This session will focus on the landscape architect’s responsibility and liability for the selection of product materials throughout the bidding and construction process. Today’s fast-paced construction market is constantly introducing new and different products and methods. Many awarded contactors have alternate products that they submit (or do not submit) for "or equal" approval. The primary reasons for selecting "or equal" products are cost, availability, and familiarity. Often there are many equal quality products available in the marketplace that represent an acceptable substitution for the specified product. However, there is a trend developing in the landscape industry whereby lower cost products, which are not of equal quality or performance, are being submitted as equal or simply substituted for the specified product without approval. This session will address the landscape architect’s continued role in product selection and the associated responsibility and liability. Also discussed are the appropriate remedies available should a contractor "illegally" substitute products. For more information, please contact Bob.Anderson@permaloc.com or visit Booth #1011. Tree Stakes and Mistakes The nursery methods practiced for the production of container grown trees are not that of the natural environment. Understanding the differences between natural tree development and containerized tree development will eliminate the confusion on how to support or how not to support the newly transplanted container grown tree. The inability of the container grown tree to remain in the upright position on its own (once the nursery stake is removed) is an unnatural characteristic caused by the effects of an unnatural environment brought about through the methods used in the art of container growing. This underdeveloped tree should not be considered as a sign of unhealthiness and with the proper method of support will begin the inherent natural process of developing the trunk strength necessary to stand-alone. Wonder Tree Tie, Inc. will explain to you that it is not the root system that plays the major role in trunk strength development; it is the natural movement of the primary stem that strengthens the bond with the primary root that allows the tree to stand alone.

It purifies the air, absorbs the rain, and sends it into the ground to recharge the vital underground water supply. It prevents erosion of the precious soil. But most turfgrass uses between 1,000,000 to 1,500,000 gallons of water per acre per year. With water shortages occurring around the world, the need to save water in the landscape is essential. This session will explore the use of new varieties of environmentally friendly turf-type buffalograss to reduce the water requirement for turf areas without sacrificing turf quality. The use of turf-type buffalograss can save 750,000 to over 1,000,000 gallons of water per year for every acre of turf converted to buffalograss. Buffalograss requires less mowing, preventing pollutants emitted by lawn mowers from entering the air. Buffalograss is a native plant to much of the world and has survived centuries on its own, without pesticides. Find out how to convert current turf areas by planting plugs without removing the old grass. Information will be provided on where to acquire the newest varieties in sod form. See why “buffalograss is not just a prairie grass anymore.” For more information, visit Booth #1217. Make Specifications Work For You!!

Designing water features that provoke excitement in people requires an understanding of art and function and a regard for form, scale, color, texture, acoustics, and environmental enhancement. A rubber liner’s ability to conform to its substrate in a variety of temperatures and terrain is essential to a water feature’s longevity and performance. While wrinkles in rubber liners do not affect the liner’s longevity, they often negatively impact aesthetics and function. Durability is a fundamental requirement of rubber liners used to waterproof water features. Firestone PondGard rubber liners are backed with Firestone’s 20-year warranty. Concrete and polyurethane foam are used with stone to create the structure of a watercourse. Concrete and foam are typically applied between two rocks, to set each rock in the water feature, and to direct the water’s flow. A rubber liner is compatible with either concrete or polyurethane foam. Landscape architects use a variety of aquatic plants and fish to naturalize
the water feature and its surrounding environment. Specify rubber liners
like Firestone’s PondGard that are an environmentally safe formulation
to ensure the protection of fish and plants. For more information, visit
