PERMEABLE PAVEMENTS
Limiting the amount of paved surfaces and other impermeable materials around the home can substantially reduce surface runoff.
- Consider alternatives to typical slab concrete when planning or replacing a driveway or sidewalk. Pre-cast concrete lattice helps stabilize soil, makes it easier to permeate and helps to control erosion. It can be installed on a bed of sand, gravel, or shells and allows rain to soak slowly downward.
- Consider using interlocking pavers for any number of paving needs. Interlocking paving stones are made of formed, compressed, durable concrete and can also rest on a bed of sand. Advantages include strength, flexibility (enables the pavers to adjust to uneven settlement), and the elimination of runoff problems as water drains between the stones and down through the sand since no mortar or binder is used.
Paving stones have great versatility, aesthetic appeal, and a wide variety of decorative shapes, colors, and patterns for patios, walkways, pool decks, and driveways. For more information refer to "paving" in your local telephone directory.
- Other alternatives to impervious concrete include: porous asphalt, bricks, tiles, flat stones (flagstone, bluestone, and granite), crushed shells or pebbles, bark chips and untreated wooden decks.
