Wetland Tracker Form Attached Text (Submitted in response to the April 2, 2007 RWQCB Conditional Water Quality Certification for the Fairfield Corporate Commons Project, Fairfield, Solano County, Corps File No. 29156N and 28457N) Box 30. Performance Standards in relation to the Fairfield Corporate Commons Project, Wetland Restoration. Taken from the Wetland Mitigation and Monitoring Plan Fairfield Corporate Commons Project Fairfield, Solano County (Mosaic Associates, et al. Sept. 2006)

Performance Standard Performance Standard Assessment

Remedial Actions

The eastern and western wetland basin floors and the two expansion areas of wetland w12 shall exhibit total vegetative cover by native and non-native wetland indicator species of at least 75%, comprised of at least 50% native wetland indicator species, by the end of the five-year monitoring period.

Vegetative cover and species shall be monitored using the point intercept method, and reported annually for five years following construction.

If the performance standard is not met, the USACE and RWQCB shall be consulted. Remedial measures might include additional seeding and extended monitoring.

The total area of wetland habitat created and restored shall be not less than 2.18 acres by the end of the five-year monitoring period.

During the late spring/early summer of the fifth year of monitoring, a formal wetland delineation shall be performed and submitted to the USACE for verification.

If the total area of wetland does not meet the performance standard, the USACE and RWQCB shall be consulted regarding appropriate remedial actions. Remedial actions might include additional seeding of wetland species, altering the flash board elevation, or grading to enhance wetland hydrology, among others.

Performance Standard Performance Standard Assessment

Remedial Actions

The wetland mitigation basins and the wetland w12 expansion areas shall exhibit saturated conditions within 12” of the soil surface for at least 5% of the growing season, or 12.5-13.5 consecutive days beginning February 1.

Six piezometers, as well as staff plates and data-loggers shall be installed and monitored monthly between December and May. The water levels shall be recorded and summarized in each annual report.

If hydrologic conditions are not observed during the first winter season, the flashboard shall be adjusted to raise water levels in the basin. If, at the end of the five-year monitoring period, the basin has failed to exhibit saturated conditions and hydrophytic vegetation has not become established, remedial measures shall be developed in consultation with the agencies. Remedial measures might include modifications to the outfall structure, grading to direct additional runoff into the basin, or creation of additional wetlands at another location.

A total area of not less than 0.07 acre of riparian vegetation shall become established on the earthen berm separating the eastern and western wetland basins.

During the late spring/early summer of the fifth year of monitoring, a formal wetland delineation shall be performed and submitted to the USACE for verification.

If the total area of wetland does not meet the performance standard, the USACE and RWQCB shall be consulted regarding appropriate remedial actions. Remedial actions might include additional seeding of wetland species, or grading to enhance wetland hydrology, among others.

Planted shrubs and vines on the earthen berm between east and west basins shall achieve a minimum average growth of two inches per year.

The height of all planted shrubs and vine lengths shall be measured annually and summarized in each annual report.

Adjustments in irrigation frequency and quantity may be made during the first three years. If, at the end of the five-year monitoring period, plant growth has not demonstrated a trend toward successful establishment, remedial measures shall be developed in consultation with the agencies.

Performance Standard Performance Standard Assessment

Remedial Actions

Riparian vegetation on the earthen berm, including planted and seeded species, shall be 75% cover by Year 3 and thereafter.

Vegetative cover shall be monitored and reported annually for five years following construction

Additional planting may be warranted if the cover standard is not met. Adjustments in irrigation frequency and quantity may be made during the first 3 years to help ensure that plants become established. If the success standard is not met at the end of the monitoring period, the USACE and RWQCB shall be consulted regarding appropriate remedial actions. Remedial actions might include making replanting and prolonged monitoring.

75% of the riparian plantings on the earthen berms shall exhibit vigor ratings of 1 or 2.

Plant vigor shall be monitored and reported annually for five years following construction

If plantings are not showing signs of meeting this success standard, adjustments in irrigation rates may be made during the first 3 years to improve plant growth established. Species substitutions may be warranted if poor vigor is common in 1 or more species. If the success standard is not met at the end of the monitoring period, the USACE and RWQCB shall be consulted regarding appropriate remedial actions. Remedial actions might include making replanting and prolonged monitoring.
