Jerry Guss Page 2 January 9, 1997 2) Install silt fence around the entire perimeter of the site. This fence needs to be inspected and approved in the field by the City's Engineering Inspector prior to November 8, 1996 A silt fence has been installed along the westerly property line. This item will also be considered satisfied for the southerly and easterly property lines because these fences are made of sheet metal panels that water does not pass through. Along the northerly property line, the entrance gate precludes the use of silt fence at the property line. However, the greatest amount of runoff from the site is coming from under the entrance gate. Therefore, you must install, prior to the next forecast rain, or January 17, 1997, whichever is earlier, erosion control measures, such as a straw bale dike or silt fence, along the bottom of the stockpile. These measures must filter all of the water leaving the site under the entrance gate. 3) From the topographic survey map you submitted on October 18, 1996, it is apparent that the ditch and reinforced concrete pipe culverts along the northerly side of Eden Road do not drain properly. Clean and regrade the ditch to provide positive drainage of the ditch from the westerly gate across Eden Road to the existing catchbasin at the westerly end of the road. Also, reset the two culverts that you installed to provide positive drainage of the ditch and culverts. The City Survey Crew has confirmed that the 2 culverts have been lowered and the ditch cleaned and regraded to provide better flow. However, the westerly culvert was set with a reverse slope of about 1 %. While your. comment that the pipe was laid in this way to protect the Bay from pollutants is appreciated, the standing water in the ditch is unacceptable. Please reset the westerly culvert at a slope to drain the ditch prior to January 24, 1997. 4) Upon completion of the above listed items, submit a new topographic survey map of the site and of Eden Road which shows the completed condition of each item. Upon receipt of the new map, Ciry staff will verify that each item has been satisfied and will release all but S2,500.00 of the balance of the deposit required in Item 1). The S2,300.00 retention will be held cis a warranty deposit to ensure continued compliance with the provisions of this letter and the Conditional Use Permit 93-14. As mentioned above, we will agree to reduce the initial deposit to $2,500. Likewise, we will reduce the retention amount to $2,000 to hold as a warranty deposit upon completion of the work. In addition to the above items, you agreed with Ken Vogeney to do the following work before the next forecast rains, or January 17, 1997, whichever is earlier: 1) Excavate and remove mud from Eden Road from in front of your gate to the gate into the City's Water Pollution Control Plant. Backfill 1-1/2 inch to 2 inch drain rock and compact to create a firm driving surface and to reduce the erosion occurring on the road.
