Ordinance Exhibit D <br />DOWNTOWN RIVERFRONT <br />LAND USE COMPONENTS <br />CA 19-1, RA 19-1, Z 19-5, WG 19-3, ST 19-3, and SDR 19-2 April 19, 2019 <br />collected and discharged from impervious surfaces). Where existing <br />native vegetation already serves this function to some extent, additional <br />native plants shall be planted in order to augment native vegetation <br />already existing. Plant species selected for all plantings shall be <br />appropriate to the site given its topography, hydrology, soil, and <br />existing native plant species. <br />Bank Enhancement Area <br />Phase One of the riparian area enhancement work scheduled for the Summer of 2019 includes a <br />regrading of the riverbank along approximately 500 linear feet of the Willamette River between the <br />existing electrical tower and the future extension of 5th Avenue. This regraded bank will be <br />temporarily secured with basalt rip -rap and seeding for overwintering prior to the 2020 construction <br />season. This initial phase of work is permitted under the Phase One Standards Review application <br />(SDR 19-001). <br />Construction and replanting work in this area for Phase Two will include removal of the temporary rip <br />rap, installation of a fabric encapsulation stabilization (burrito) system followed by extensive <br />replanting with native tree, shrub, and forb species. See sheets WR104.1 and WR104.2 (Exhibit 13.3: <br />Standards Review Plan Set) for planting information and details. This planting scheme will be the final <br />condition for this area which represents a significant improvement in bank conditions for this area <br />from a steep rip -rap condition, to a gentler fully planted condition. These improvements will assure a <br />higher diversity of plants, greater distances for storm water filtration and infiltration prior to entering <br />the river, and potentially better habitat for birds, insects, and ideally fish. <br />Bridge Access Path Area <br />All work in this area will be completed in Phase Two under this approval. Grading in this area will <br />facilitate the construction of a new path and create new planting opportunities all around the path. All <br />stormwater runoff from the path will be treated per applicable City Code prior to entering the river, <br />and all new plantings will be species from the Goal 5 Native plant list. These new plantings will be <br />irrigated and maintained in the future as a developed park amenity maintaining the safety of the path <br />and views to the river. Again, the proposed condition will be a significant improvement over the <br />existing steep bank and non-native and invasive species vegetation in this location. <br />Therefore, this standard is met. <br />(b) Planting or replanting within 25 feet of a Category B, C, or D stream <br />within the /WR conservation area shall include native tree or large <br />shrub species and located so as to provide substantial shading of the <br />channel during times of peak solar input. <br />(c) Where non-native or damaged trees are removed within 25 feet of a <br />Category B, C, or D stream within the /WR conservation area, they shall <br />be replaced with native tree or large shrub species and located so as to <br />achieve equal or greater shading of the channel during times of peak <br />solar input as the trees removed. <br />The Willamette River is a category 'A' stream, therefore these standards are not applicable. <br />(d) Replanting of areas cleared of existing vegetation must be completed <br />within 90 days following the removal or clearing, unless otherwise <br />approved by the planning director. <br />City of Eugene FINAL SUBMITTAL 89 <br />
