WET-4 to be converted to biofiltration pond. Natural Material Trail (mulch or decomposed granite) with Educational Signage in Buffer Area - Provides community opportunity to experience and be educated on wetland functions Remainder of Buffer area will be kept in natural state and protected from regular mowing by restrictive covenant. Water Quality · Water Quality Controls will consist of Biofiltration Ponds and Rain Gardens or other approved permanent BMPS's Residential Lots adjacent to wetlands and wetland buffers will drain towards buffer to maintain drainage area to wetlands and allow wetlands to provide natural water quality pre-treatment to runoff. Culvert Crossings · Culvert Crossings will consist of multi-barrel, low head culverts to maintain more natural dispersed flow patterns. This will provide lower exit velocities and reduce potential for scour. Plantings Restoration Plantings A: · Riparian Recovery Seed Mix of herbaceous riparian plants native to the Black Land Prairie. Restoration Area A will be limited to the non-impacted CEF footprints and Biofiltration ponds within Area 1 Ex. Bushy Bluestem and 33 other species of native forbs and grasses. Restoration Plantings B: · Riparian Recovery Seed Mix of herbaceous riparian plants native to the Black Land Prairie and selective trees approved by the City of Austin. Restoration Area B will be planted/broadcasted between the space between the CEF and Pond Footprints and the inner edges of the Nature Trail in Area 1 and within the entirety of Area 4A. Where there is no trail present around the CEF (as in Area 1A), the 50-ft CEF buffer will be used. Tree species considered for planting include but are not limited to Bald Cyprus, Black Willow, Bur Oak, and Pecan. To ensure a diverse structure, different classes of trees will be planted and seeds broadcasted when possible. Restoration Plantings C: · Upland Wildflower Seed Mix. Restoration Area C exists between the Nature Trail (or 50-ft CEF buffer) and the remaining extent of the Enhancement Areas. 36 species of native forbs and grasses. Ideal for pollinators i.e. native bees, Butterflies etc. · · · · · · · · I I I N O S V D B U S T O L L L A M S A , E N A L D R A W O H CASE # C8J-2019-0143 SHEET OF 5 5 M P 5 0 : 1 2 : 2 0 2 0 2 / 8 / 9 : d e t t l o P L A Q W : t - - u o y a L g w d .
