Some silt fences installed. However, they do not extend the silt fences across across the driveway entrance and much of the street frontage. Reported to the City on May 2.

This builder is now using straw wattles to protect against erosion. The City’s Watershed Protection Department won’t even provide specifications in their Environmental Criteria Manual (ECM) because they say they don’t work. Quoting the City Watershed Protection Department:
"Moving on the design criteria for specific E&S controls, the ECM contains the controls that are acceptable to meet the LDC as well as installation and design guidance. Straw wattles are not listed as acceptable controls in the ECM because they do not provide robust control of the 2-year storm as required in the ECM. Instead, the ECM provides design and installation guidance for Mulch Socks. Similar to Straw Wattles in shape and purpose, Mulch Socks are larger and more robust, able to quantitatively provide on-site control of the 2-year storm erosion when installed and maintained properly. COA does not anticipate adding criteria for Straw Wattles due to their limited effectiveness."

The silt fence has a gap in it rendering it ineffective. Sediment has escaped into the gutter and down the street.

There are no erosion controls along this part of Bluff St. The only thing that will prevent sediment from leaving the site is for it not to rain.
