Rawson fails to clean mud from box culvert

The Rawson construction site on Old Middleton Rd is a mess--completely unprepared for rain.  In their defence, no rain was forecast for the weekend.  But much work remains to prepare for the rain forecast for next Thursday.

There's a lot to fix before the next storm:
  1. Terraces on hillsides are all bare, with no protection.
  2. Many inlet filters are clogged.
  3. Steep slopes on the east side of the road near the creek are unstabilized.
  4. Banks of the stream, just above the box culvert, are unstabilized.
  5. The gutters are filled with soil and gravel in many places.
  6. A pile of soil next to pavement, corner of Old Middleton and Helm, is unprotected.
  7. At least two silt frences are down.
Rawson fails to clean mud from box culvert

Before an earlier storm, Rawson neglected to close the opening of the box culvert they had just laid under Old Middleton Rd.  As a result, muddy runoff from their site filled the culvert, and a thick layer of mud was deposited.  We brought this to the attention of the City, and the City asked Rawson to clean out the culvert.

But when we inspected the culvert today, we found only about the first 10 feet downstream had been cleaned (what you can easily see from outside).  The rest--the bulk of the culvert--hadn't been cleaned at all.

Cleaning the culvert is important...
In the next big storm, this mud will be washed half a mile to L. Mendota.

Rawson damages trees

One large tree had a gash in it's trunk at least two feet long.   

A second tree also had a large gash, and a third had minor root damage.
