New & Noteworthy: Land Development

Dust and erosion control

The Specialty Products Division of United States Gypsum Company says that its Dustrol Dust Control controls wind erosion, minimizes dust, and stabilizes soil using just one product. The gypsum plaster and liquid hydration inhibitor system is mixed with water and wood fiber mulch or cellulose, along with No-Go hydration inhibitor. It forms a cementious binder that produces a crust-like barrier. Dustrol can be mixed and applied using a conventional Hydroseeder machine. It requires only normal surface preparation and can be used with a variety of mulches. According to the company, the product also provides nutrient benefits to soil (calcium and sulfur).

Stormwater system design

For design engineers or architects focusing on commercial and retail site development, Advanced Drainage Systems, Inc., created a tool to assist in developing complete stormwater drainage systems. The interactive CD-ROM uses a dynamic rendering to show where various drainage products, including pipe, fittings, chambers, structures, geosynthetics, and water quality units, can be used. Also included are detailed product descriptions, installation details, and insertable CADBlocks of all the company’s products for direct use in all design platforms. The design tool further includes technical reports, product notes, calculation tools, and other support literature.

Site design software updated

Carlson Software’s Carlson Civil 2007 is the next generation of the product line formerly called SurvCADD. The new release includes more than 50 new commands and 150 improved commands across the program spectrum comprised of survey, site and road design, hydrology, and GIS. Carlson Civil 2007 works with AutoCAD 2007 and previous releases. New features include dynamic road networks with integrated intersection and cul-de-sac design, dynamic storm sewer networks with DTM-based automatic drainage areas, mass haul analysis to report optimized earthwork movement by distance ranges, automatic point label overlap avoidance, deed reader to extract line/curve data from deed text, and coordinate file history. The new Point Clouds module registers, views, decimates, and filters laser scan data, and generates models as well as layerized linework and points.

Constructed wetland design manual

The just-released design manual, Small-Scale Constructed Wetland Treatment Systems: Feasibility, Design Criteria, and O&M Requirements, by Scott Wallace, P.E., senior vice president of North American Wetland Engineering, LLC, presents criteria for the feasibility, design, operation, and maintenance of small-scale wetland systems for decentralized wastewater management. Data from 1,640 small-scale treatment wetlands was used to develop sizing criteria for the two most common types of small-scale treatment wetlands—free water surface wetlands and vegetated submerged bed wetlands. The manual also includes confidence intervals for design criteria, allowing designers to assign a factor of safety to a given wetland design; basic information on wastewater generation; the feasibility of wetland technology; and internal treatment processes in constructed wetlands, as well as important design issues such as hydraulic considerations, cold-climate performance, operations and maintenance, vegetation establishment, and construction costs.

Smaller ditch lining system

Penda Corporation’s SmartDitch line now includes a 12-inch trapezoidal design, which is a direct extension of its 30-inch liner. SmartDitch liners are constructed from high-density polyethylene, which, according to the company, resists punctures and withstands extreme heat and cold. A modification to the 12-inch product incorporates a serpentine design that runs along the bottom of the channel lining system to minimize standing water. The 12-inch liner is designed to be flexible to accommodate meandering channels and sharp turns; it is able to bend 90 degrees along the edge of a 10-foot radius. An improved anchoring system attaches perpendicular to the side walls of the liner, and sections are fastened together with screws. The liners are available in black, green, brown, and tan and can be placed above ground or in an existing unlined or concrete-lined ditch.

Environmentally safe soil stabilizer

Midwest Industrial Supply received two patents for its technologies in the development of compounds and their use to produce a new category of soil stabilization and dust control products. Historically, the company said, attempts have been made to use white oils and isoalkanes as dust suppressants. These efforts proved unsuccessful because of the relatively high cost and short-term effectiveness for dust control and soil stabilization. Midwest Industrial Supply discovered a way to maximize the effectiveness of synthetic isoalkanes as a dust control and soil stabilization agent by formulating with select organic binders. These formulations are used to manufacture the new category called "synthetic organic dust control" for soil stabilization and dust control products. Midwest makes this technology available under the registered trademarks EnviroKleen, EK35, Diamond Dr., and Arena Rx, all of which it says are environmentally safe.
