The City completed is erosion-control and tree-protection fencing this week. Erosion-control fencing, also known as silt fencing, keeps loose dirt from being scoured off the site during rainfall and flushed into the creek at the bottom the ravine. It is a common environmental protection measure. The fencing fabric is usually made out of a black plastic fabric, shown in the photo to the right.
In addition to the erosion-control fencing, the City's contractor also installed tree protection fencing, shown in the next photo. This fencing keeps construction equipment and personnel out of the root zone of trees to ensure the construction has minimal impacts to those trees.
You'll notice in the next photo, below, that they also installed some crushed stone to fill a small ditch. This stone will allow construction equipment into and out of the site, while still allowing rainwater to percolate through the ditch.
The City also did a small amount of vegetation removal as well, piling some old brush root balls on the site. Now there will be inspections by the Montgomery County Department of Permitting Services. Once the County department gives its thumbs up next week, construction will start in earnest.
