CMI Homebuilder's Inc. Wetlantl Delinealion and actual sightings, while indirect observations include tracks, scat, nests, song, or other indicative signs. The kinds and locations of the habitat with greatest use by each species will be noted, as will any breeding or nesting activities. 9.3 Hydrology, Water Quality, and Site Stability During each monitoring event, an assessment will be made of the water regime within the wetland and buffer areas to ensure that proper hydrological conditions exist. General observations will be made of the extent and depth of soil saturation or inundation. Water quality will be assessed qualitatively, unless it is evident there is a serious probiem. In such an event, water quality samples will be taken and analyzed in a laboratory for suspected parameters. Qualitative assessments of water quality inciude: • oil sheen or other surface films, • abnormal color of water or odor, • stressed or dead vegetation or aquatic fauna, • turbidity. Observations will be made on the stabiiity of siopes in the mitigation areas. Any erosion or slumping of the slopes will be recorded and corrective measures wiil be taken. 10.0 SUCCESS CRITERIA FOR PLANT ESTABLISHMENT Success of plant establishment within the mitigation area will be evaluated on the basis of both percent survival and percent cover ot desirable species. For woody planted species, success will be based on at least an 80% survival rate of all planted trees and shrubs, or at least 60°/o cover of equivalent recolonized native species, by the end of the five-year monitoring period. For emergent plantings, success will be based on at least 60% cover by the end of the five-year monitoring period. Success for seeded areas wili be based on 90°/o cover after the first growing season and 100% wver after the second growing season. Reseeding wili occur as necessary to meet this coverage standard. In addition, single patches of bare ground larger than 50 sf will also be reseeded, after reason(s) for failure has been determined. Exotic and invasive plant species will be maintained at levels below 20% total cover. Undesirable species may include ScoYs broom, Himalayan and evergreen blackberry, reed canaygrass, purple loosestrife, hedge bindweed, Japanese knotweed, and creeping nightshade. Removal of these species will occur immediately following the monitoring event in H-hich they surpass the above maximum cnverage. Removal will occur by hand whenever possible. 11.0 MAINTENANCE (M) AND CONTINGENCY (C) Maintenance will be performed twice per year to address any conditions that could jeopardize the success o� the mitigation area. Established performance standards for the project will be compared to the monitoring results to judge the success of the mitigation pruject. If there is a significant p�oblem with achieving the performance standards, the bondholder shall work with the City to develop a contingency plan. Contingency plans can include, but are not limited to: addiiional plant installation, erosion controi, modifications to hydrology, and plant substitutions of type, size, quantity, and location. Contingency will include many of the items listed below and wouid be implemented if these performance standards are not met. Maintenance and remedial action on the site will be implemented immediately upon completion of the monitoring event (unless otherwise specifically indicated below). 20 May 2003 Talasaea Consultants, LLC 364C-MilRpt4(ZOMay03).doc page9
