planting/relocation of the vegetation and shall end 90 calendar days after acceptance of the vegetation work by the COUNTY. The CONTRACTOR will be responsible for obtaining, paying for and applying all irrigation water used under this bid. Freshwater (potable only) shall be provided and applied to the planting zones using either a CONTRACTOR-installed irrigation system or a non-scouring spray applicator. It should be noted that size and weight limitations of vehicles operating on the beach and dune in the Project Area will be in effect subsequent to March 1 . CONTRACTOR shall specify means of watering to ENGINEER and OWNER as a component of the Operations and Environmental Protection Plans described in Sections 8 and 13 of these Technical and Environmental Specifications. 43 . 13 Inspections and Approvals. The COUNTY will conduct performance inspections of the dune plantings following the completion of the vegetation work in each reach and at the completion of the 90-day maintenance period. At the completion of the 90-day vegetation irrigation and maintenance period, the COUNTY shall conduct final inspection and approval of the plantings. During the inspection, the COUNTY shall verify that 90 % of all plantings are in a healthy growing condition. If the plantings do not meet these criteria, the CONTRACTOR shall be required to replace unhealthy or deceased plants as identified by the COUNTY. Once the COUNTY verifies that the final inspection criteria have been met, the COUNTY will submit final written acceptance of the plantings to the CONTRACTOR. 43 . 14 Success Criteria and Reolantinn 43 . 14. 1 Planting Unit Success Criteria. The success of the planting effort will be determined by the COUNTY approximately 90 days from the end of the plant installation using two measures: reach survival rate and planting unit survival pattern . The planting effort shall be deemed a success if both of the described criteria are met at the 90 % level . 43 . 14.2 Reach Survival Rate. A minimum survival rate of 90% of all plants installed over the reach as a whole shall be achieved. Plants will be considered to be surviving if they show clearly vigorous rhizomes and white, turgid roots, even in the absence of vital above-ground growth. 43 . 14 .3 Survival Pattern. A minimum of 90 % of the planting zone width perpendicular to the shoreline shall be occupied by surviving planting units at all locations. For the typical 60-foot planting zone (92 plants per 60-foot section), a total of 87 surviving plants must be present within any 3-foot wide perpendicular transect through the planting zone. This success criterion may be waived, at the discretion of the COUNTY, in areas where plant survival has been adversely impacted by unexpected pedestrian traffic. 43 . 14.4 Replanting of Planting Units. If any of the above success criteria are not met, as determined by the COUNTY, the CONTRACTOR shall replant with viable, and within specification, planting units in all areas considered to be deficient according to TECHNICAL AND ENVIRONMENTAL SPECIFICATIONS Ree October 5 . 2007 TS-47
