[CONTINUED PROJECT TITLE]: that which presently exists. North County Facilities The North County exempt facilities include concrete channels, earthen road-side ditches, earthen channels, basins within developments, grassy swales, and facilities that are part of the Santa Maria Valley drainage network which include retention and recharge basins. General maintenance includes periodic silt management and the control of weeds. Over the past several years the District has been utilizing mowing for weed and fire control rather than the use of herbicides, although herbicides are still used, but in much lower amounts. The most common weeds that are controlled are Russian thistle, cat ear, wild radish, cape ivy, rape seed weed, myoporum, oleander, fennel, tree tobacco, and mustard. Non-native grasses are also mowed for fire control purposes. Occasionally, the District will remove cattail or bulrush seedlings if they begin to colonize wetted areas near the outlet of a basin. Also, occasional mulefat or coyote bush seedlings are sprayed. The District will conduct herbicide application in the facilities listed below beginning May 1st, and desilting and mowing of non-native vegetation beginning June 1st of the year following that Annual Plan’s approval. Santa Maria/Guadalupe Area: Ditches: 1. Blosser Ditch: This is an asphalt or concrete ditch from Fessler Road downstream to Blosser Basin, a distance of approximately 1.5 miles. The earthen portion of this channel begins downstream of the basin and continues downstream to the Santa Maria River where it enters a flap gate through the Santa Maria River Levee. Between Alvin Road and Donavan Road (a distance of approximately 2,600 feet) the channel is asphalt and sediment tends to settle out requiring desilting. Additionally, weep holes in the concrete lined section and cracks in both the concrete lined and asphalt sections are spot sprayed with herbicide on an annual basis so the cracks don’t get larger from the weeds growing in them and the weep holes remain functional. Desilting is done on a biannual basis and will not be done this year. Potential Area of impact is less than 100 square feet from spot spraying. Refer to Page 4 for the location of this facility. 2. Bradley Ditch: This ditch is approximately 3.5 miles long and is approximately 75% concrete and 25% earthen.

Additionally, on a biannual basis, seedlings are sprayed in the concrete V-ditch to keep the ditch from deteriorating. Potential Area of Impact from mowing is .17 acres and less than 50 square feet for spot spraying seedlings in the V-ditch. Refer to Page 7 for the location of this facility. 4. Crescent Avenue Ditch: This is a concrete V-ditch with earthern sides. It is approximately .75 miles long. On a biannual basis a Kubota is used to desilt portions of the V-ditch.
