2) Water Circulation and Drainage Plan, Initial Study/Negative Declaration, dated October 29, 1993 (pp.52-59), copy attached (Exhibit A-2); 3) Corps of Engineers Permit No. 17965E50B as modified dated September 22, 1993, copy attached (Exhibit A-3). 3) BCDC Permit No. 14-89 as amended dated April 15, 1994, copy attached (Exhibit A-4). TASK SUMMARY The Contractor shall perform the monitoring and reporting activities on an annual basis as detailed in attached Exhibit A-1. The tasks are generally as described below: Task 1. Vegetation Surveys Vegetation cover monitoring and data collection shall be accomplished by the Contractor along six transects in the North Marsh, five existing transects in the East Marsh, and four existing transects in the Bunker Marsh/Lower Roberts Landing Slough. The following measures of vegetation characteristics shall be made along each transect: (1) estimates of percent cover of plant species; and (2) measure of average plant heights. The Contractor shall also collect vegetation percent cover data in transitional areas such as the islands and upland areas converting to salt marsh. Task 2. Bird Surveys One day bird surveys shall be made every two months accounting for seasonality and tide level. The surveys shall be made by following existing transects, with 15 minute observations made at defined points along the transects. Task 3. Hydrology/Sedimentation The hydrologic regime shall be monitored by measuring the actual frequency, extent, and duration of tidal inundation against that predicted in the Water Circulation and Drainage Plan, dated January 25, 1991, and Amendment, dated November 22, 1992. Existing water elevation measuring staffs shall be maintained in their current locations within the main channels of the North and Bunker Marsh areas to enable accurate assessment of water depth and elevation. On an annual basis, during different tidal scenarios as necessary, observations of the hydrologic regime within the area shall be made to evaluate tidal range, percent of area inundated, and culvert and channel operation.
