Best Management Practices

Low Impact Development has been the focus of numerous conferences and seminars across the country. Universities have incorporated low- impact development into curriculum for future architects and engineers. This push for more sustainable, responsible construction practices is not going away. As the feasibility of Low- Impact Development (LID) practices is pitted against conventional construction practices, research and practice indicate that LID is not only more environmentally sound, it is more cost- effective. Consumers, both commercial and residential, are increasingly more attuned to the green movement. Industries across the board have begun stocking products with labels such as Certified Organic, Made with 51% Post Consumer Waste, Biodegradable, Made with Eco- Harvested Wood Products, Fair Trade, etc. Consumers will soon demand similar labels on their structures; i.e. LEED Certified, Green Roof, and Irrigated with Harvested Rain Water. Consider some of the information presented in the following links and turn your operation green (financially and environmentally)!
Do's & Don'ts for Construction Sites
The Notice of Intent (NOI) or construction site notice should be located next to the entrance of a construction site, preferably near the street. Written on the construction site notice is the location of the SWP3, a description of the project, and the name and contact number of the person(s) responsible for inspections on the site. DO
Proper implementation of BMPs really does make a difference! DO
This silt fence is properly installed. You can see that the fence is well secured. The posts are metal T-posts, there is a supporting wire structure, and the fence is buried. Also, this silt fence has been well maintained. The build up of silt and soil has been cleared so that the fence can continue to function properly.
These inlets are very well protected, using techniques and materials suited to the construction activities and inlet locations.
Entrances to construction sites should be lined with rip-rap free of loose soil. Once the soil covers the rip-rap this BMP no longer works properly so additional rip-rap should be added. To keep workers from entering and exiting at different locations, a fence could be placed around the perimeter of the construction site. DON'T
Concrete should never be washed out onto the ground or streets. The best alternative would be to contain the leftover concrete, let dry, and then dispose of the dried concrete at a landfill. DON'T
Building materials that are not intended to be exposed to the environment, such as this wire mesh and steel rebar, should be covered and off the ground. DON'T
If the construction site slopes toward the street, a silt fence should line the outer perimeter to keep soil off the street and workers from entering the site at any location. The soil that enters into the street needs to be placed back onto the construction site to avoid being deposited into nearby playa lakes. DON'T
Large stockpiles of dirt should have a silt fence around the entire perimeter. If the stockpile of dirt is not scheduled to be disturbed for a long time, some sort of cover (mulch, seeding, turf blankets, etc.) should be placed over it to avoid erosion by wind and rain. DON'T
Trash containers should be covered whenever possible to avoid having trash blow away with high winds. DON'T
These silt fences have not been properly maintained. The fences were put up using wooden stakes without wire backing. Additionally, the silt fences were not buried.
