<br />I t...UUJ <br /> <br />. <br /> <br />Port of Houston Authority <br />Wetland Mitigation Plan <br /> <br />e Port of Houston Authority N.1520(Revised) <br />Galveston Bay, along the Bayport~hip Channel, <br />City of Pasadena, Harris County, Texas. <br />Attachment 1, Sheet D ofJLf:(Revised May 2003) <br /> <br />MONITORING <br /> <br />The PHA will conduct Wetland Monitoring to document wetland success. Wetland performance <br />monitoring will be conducted in two phases: <br />Phase I, which is considered a post-planting growth phase, will be initiated after construction <br />and planting are complete, and will continue for three (3) years. Phase I activities will include <br />monitoring and maintenance. Wetland performance standards will be met before Phase I is <br />concluded; <br /> <br />Phase II, a performance maintenance period, begins after the conclusion of Phase I. Phase II <br />will continue for two (2) years to assure performance standards achieved during Phase I are <br />maintained. <br /> <br />. <br /> <br />During both Phase I and II, monitoring will be conducted using both qualitative and quantitative <br />field methods. The methods employed during a particular monitoring event will be dependent <br />upon the specific objective for that Phase or monitoring event. Qualitative monitoring will <br />involve visual inspections, ground-level photographs, and professional judgment of the field <br />biologists. Quantitative surveys may include aerial photography to document growth trends and <br />surveys of vegetation survival and growth. Quantitative monitoring will be used to document <br />progress toward performance standards. <br /> <br />Monitoring Schedule and Requirements <br /> <br />Phase I Monitoring <br /> <br />Marsh creation will begin within a year of the date if initial construction at Bayport. Phase I <br />Monitoring of the wetland creation project will be initiated after planting of marsh vegetation is <br />complete and construction has been approved by the USACE. The completion of planting shall <br />serve as time zero for monitoring, reporting, and time related Success Criteria (i.e., the initiation <br />of Phase II). The objective of Phase I monitoring will be to document vegetation survival and <br />growth trends in the constructed wetland. During Phase I, PHA will monitor marsh development <br />at least twice during the first growing season, and semi-annually until performance standards <br /> <br />. <br /> <br />Benchmark Ecological Services, Inc. <br /> <br />May 2003 <br />
