Riparian Management Plan-All management zones to be planted following completion of all site grading and ground stabilization as prescribed inapplicable erosion control plans and documents.-Replanted stream buffers are to remain forested following restoration and will be marked with signage indicating “Riparian -Management Area: No Tree Cutting”.-All management zones will be planted with an even species composition per Tree Planting Matrix as follows:Zone A- Mix 1: 12 treesZone B- Mix 2: 60 trees-Plantings will be spaced unevenly with random species distribution on spacing averaging 20-25’ between stems.-All plantings to be guaranteed for a period of 2 years at which point any dead or dying trees are to be replaced.-Following planting, an As-Built plan will be prepared followed by annual monitoring for a period of 3 years (4 years total).

Project Phasing:All proposed construction activites in the vicinity of the Riparian Management Areasto be completed fully and stabilized prior to implementation of RiparianManagement Plan. This includes activities associated with the skiback tunnelconstruction as well as proposed Master Plan activities such as replacement of theexisting Oak Brook culvert, installation of utiity, water and sewer infrastructure, roadreconstruction, etc. An existing work road in the area of Riparian ManagementZone A, west of the Skier Bridge, will continue to be utilized during constructionactivities.

Upon completion of proposed construction activities in the vicinity, currentlyanticipated for late 2016, the work road west of the Skier Bridge will bediscontinued. Any gravel surface will be removed, finished with topsoil andstabilized with conservation seed mix and straw mulch followed by implementationof this Management Plan.
