If bare root plants are used, they must be planted during the late winter/early spring dormancy period. **Minimum quantities to be planted. Planting Notes (per CWS Design & Construction Standards R&O 19-5, amended by R&O 19-22, December 2019 Appendix A Planting Requirements): 1) Container stock shall be installed only from February 1 through May 1 and October 1 through November 15. Bare root stock shall be installed only from December 15 through April 15. Plantings outside these times may require additional measures to ensure survival which shall be specified on the plans. 2) All non-native invasive vegetation shall be removed from planting areas prior to installing native enhancement plantings. Invasive species control shall be consistent with Clean Water Services' June 2019 Integrated Pest Management(IPM)Plan. 3) Appropriate plant selection, along with adequate site preparation and maintenance, reduces the need for irrigation. However, unless site hydrology is currently adequate, a District/City approved irrigation system or equivalent (i.e., polymer, plus watering) shall be used during the two-year plant establishment period. Watering shall be at a minimum rate of at least one inch I( Bonita Villa Apartments-Tigard August 2021 Vegetated Corridor Enhancement Planting Specifications Page 1 per week from June 15 through October 15.Other irrigation techniques,such as deep watering, may be allowed with prior approval by District staff. 4) Trees, shrubs, and groundcovers planted shall be mulched at a minimum of three inches in depth and 18 inches in diameter,to retain moisture and discourage weed growth around newly installed plant material.Appropriate mulches are made from composted bark or leaves that have not been chemically treated. 5) Tree and shrub plantings shall be tagged. 6) Depending on site conditions, appropriate measure shall be taken to limit wildlife-related plant damage(see 1PM Plan). Maintenance Plan 1) Clean Water Services requires a two-year maintenance period for vegetated corridor enhancement.The enhanced vegetated corridor is to be inspected annually and a minimum of three times during the growing season and one prior to the onset of the growing season over the two-year monitoring period. 2) Plant Survival: Clean Water Services' success criterion for vegetated corridor enhancement is 80%survival of tree and shrub plantings during the two years following planting. If any mortality is noted on the site,the factor likely to have caused mortality of the plantings is to be determined and corrected if possible. If survival falls below 80%at any time during the two-year maintenance period, the plantings shall be replaced and other corrective measures,such as mulching or irrigation, may need to be implemented. If replanting is necessary,the maintenance period will be extended for two years from the date of replanting. 3) Invasive species control is to be conducted as needed based on the site inspections. Invasive species include Himalayan blackberry(Rubus armeniacus), reed canarygrass(Phalaris arundinacea), teasel (Dipsacus fullonum),Canada and bull thistle (Cirsium arvense and C. vulgare), Scotch broom (Cytisus scoparius), purple loosestrife (Lythrum salicaria),Japanese knotweed (Polygonium cuspidatum), morning glory(Convolvulus species),giant hogweed (Heracleum mantegazzianum), English ivy (Hedera helix), nightshade(Solanum species), and clematis (Clematis ligusticifolia and C. vitalba).
