If the structure of the specimen iscompromised due to repetitive improper cutting techniques, the specimens will be flush cutand managed as a stump sprout.MAINTENANCE (3 SEASONS MIN.):·Monitor restoration area and perform maintenance cut and wipe treatments, selective foliarapplications, or hand weed invasive, non-native, and aggressive species that havegerminated from existing seed bank, or re-sprouted from roots after removal.·Mow/cut seeded areas in early spring and/or in June to help establish warm season grasses,if necessary.·Site will be monitored and maintained throughout the year for both cool season and warmseason invasive, non-native, and aggressive species.RESTORATION PLANTING:·Plantings to be installed after invasive vegetation has achieved a minimum of approximately80% eradication.·Plantings to be installed in the spring or fall unless supplemental irrigation is installedimmediately after planting.APPLICATOR & OVERSIGHT REQUIREMENTS:·Herbicide application will only be completed by Massachusetts state-licensed and insuredpesticide applicators knowledgeable with invasive, non-native, and native plantidentification, both in-leaf and bare-twig.·All restoration work will be overseen by a Certified Ecological Restoration Practitioner (CERP).PLAN NOTES:CONSTRUCTION & MAINTENANCE:·Primary access for construction and nourishment/ maintenanceactivities will be from the existing driveway on the property, over thelawn area.·Nourishment over fiber rolls will require approx. 21 cubic yards at initialimplementation.·Patio sub base to be reinforced to address slumping on southeasternside.·Existing walkway to association dock to be maintained.ANNUAL NOURISHMENT:·Nourish the installation with compatible sediment as necessary tomaintain design profiles as shown on the plan. Nourishment needs mayvary from year to year for volume and frequency.·Nourishment is to be placed in the spring each year as necessary tomaintain the beach elevation.ONGOING MAINTENANCE:·Monitor project area and perform assessments after a significantweather event to determine how the installation is performing and ifany changes or additions to the installation are necessary.·Any areas of the installation or components that are damaged,degraded, or exposed will either be repaired/replaced or the exposedportions will be removed.SUPPLEMENTAL IRRIGATION:·Install a temporary, above-ground irrigation system to providesupplemental water to woody plantings for 2-3 growing seasons or untilplants are fully established.MATERIAL INFORMATION·All lumber for stair construction will be non-CCA (Chromated copperarsenate) treated.
