Once the perimeter is stabilized then the developer can clear uphill areas of the site.

Bulldozers and other heavy equipment cut and fill sloping sites to create the relatively flat areas needed to begin building roads, houses and other structures.

When this point is reached the site is said to be at Rough Grade. Many localities will require stabilization of all areas of exposed soil once rough grade is reached.

Road and parking lot beds are stabilized with four inches of stone. All other areas are stabilized with enough straw mulch that underlying soil cannot be seen. Areas that will remain idle for some time are stabilized with mulch and grass. Of the two approaches, erosion control through stabilization measures is far more effective compared to perimeter sediment trapping measures.

The rest flows offsite into a nearby waterway. Erosion control is the only measure that can keep the most polluting soil particles - clay - from flowing into nearby waterways.

So, whenever you see exposed soil on a construction site you can assume a nearby waterway will be polluted come the next major storm.

Stormwater Management Following is a description of the Best Management Practices BMPs used from the late s on to manage stormwater runoff from new development.

The earliest ponds were designed to control severe flooding by managing a storm recurring an average of once every years.

After development the volume of runoff might double or quadruple. The pond was sized to store the difference in runoff before and after development. The opening on the vertical spillway pipe riser was sized to release the stored runoff at the same rate that occurred prior to development.

The ten-year storm was added to minimize the impact of lesser flood events. Next, ponds were designed to manage the two-year storm, which was thought to be key to minimizing channel erosion. Today, many states require management of the one-year storm for channel protection.

Additionally, many states require passing the monthly storm through water quality BMPs designed to trap pollutants.

The monthly storm produces about an inch of runoff from impervious surfaces. Some states require infiltrating a lesser amount of runoff to maintain groundwater recharge at predevelopment rates. Soils are assigned to one of four Hydrologic Soil Groups HSG based on permeability and the amount of runoff generated.

Soils assigned to HSG "A" tend to be sandy and produce the least runoff.

But these BMPs can be used on even "D" soils but an underdrain is needed, which negates groundwater recharge and probably some pollutant removal.

There's a wealth of other information available at Web Soil Survey. In the early days, Dry Ponds were the most common measure. These ponds were designed to store excess runoff from the year storm then release it gradually after a major storm passed.

As the name implies, Dry Ponds had a large opening at the bottom of the spillway which allowed it to drain completely once runoff subsided. Since there was no place to store pollutants these facilities provided zero water quality protection, no groundwater recharge and probably made stream channel erosion worse.How to Get Rid of Pool Algae.

Vincent Ingram View Local Pool Companies. Where there’s water, there’s life. While this may be a rallying cry for astronomers in search of ET, it’s a far more troubling prospect for pool owners. Add in the fact that these bacteria use algae as a food source, and you have a rapidly multiplying health.

In , Bredesen published a paper that demonstrates the power of lifestyle choices for the prevention and treatment of Alzheimer's. By leveraging 36 healthy lifestyle parameters, he was able to reverse Alzheimer's in 9 out of 10 patients.

SPRINGTAIL FORAGING FOR FOOD. Springtails are small insects which thrive where there is a lot of moisture. They can be white, tan, brown and black and during the warm season may be seen in bathrooms, kitchens, basements, crawl spaces, behind walls, under siding, under mulch and just about anywhere moisture is prevalent and persistent.

Spas or hot tubs with naegleria have been found to be sources of eye infection, often confused with pink eye. Infections have most often been associated with swimming in lakes and ponds where infection is known, but few infections have been found in swimming pools.
