ECM of Urban Land - Gravel Access Path
Gravel Access Path:
Gravel or rock driveways in construction sites can minimize tracking of soil or sediment into the streets by vehicles and equipment. In addition, compaction of soil on the rest of the construction areas is reduced by limiting vehicle movement to the gravel or rock driveway. Temporary rock areas should be underlayed with appropriate geotextiles. This limits the incorporation of rock into existing soil, which will support future plantings.

Soil Facts
Soil compaction results when soil particles and aggregates are compressed together. This compression reduces the empty spaces or pores of the soil. This increases the bulk density of the soil. Compaction reduces soil aeration, water infiltration, drainage, and ability of roots to penetrate into the soil.
Unless gravel roads are in place and vehicle traffic is minimized, it is highly probable that vehicles will track soil into streets. The impact of soil tracked into paved roads can be significant since any rainfall runoff will carry this soil or sediment directly into the storm drainage system. If the soil has been tracked onto the pavement, the goal should be to minimize its movement into drainage ways. A practical and cost effective way to do this is to sweep or scrape soil on the paved road daily before it is moved by rainfall runoff.
