Plant species that are non-native and invasive; 2. Dead or dried native plants or grasses only when they constitute an imminent fire hazard; 3. Living native or non-native vegetation, when its removal is necessary to facilitate or encourage the growth of other native species (e.g., native wet prairie plant species) consistent with adopted plans or policies; or 4. The minimum area of native vegetation removal necessary to accommodate uses approved in accordance with EC 9.4930(3)(a) through EC 9.4930(3)(h), and uses approved through an adjustment approved in accordance with EC 9.8030(21). (b) Clearing of more than 500 square feet of vegetation must comply with Erosion Prevention regulations for sensitive areas in EC 6.645. (c) Any clearing of vegetation that is not within the footprint of uses approved in accordance with EC 9.4930(3)(a) through EC 9.4930(3)(h), or uses approved through an adjustment approved under EC 9.8030(21), must be followed by replanting in accordance with the requirements of subsection (3) below.

Where existing native vegetation already serves this function to some extent, additional native plants shall be planted in order to augment native vegetation already existing. Plant species selected for all plantings shall be appropriate to the site given its topography, hydrology, soil, and existing native plant species. (b) Planting or replanting within 25 feet of a Category B, C, or D stre'am within the /WR conservation area shall include native tree or large shrub species and located so as to provide substantial shading of the channel during times of peak solar input. (c) Where non-native or damaged trees are removed within 25 feet of a Category B, C, or D stream within the /WR conservation area, they shall be replaced with native tree or large shrub species and located so as to achieve equal or greater shading of the channel during times of peak solar input as the trees removed. (d) Replanting of areas cleared of existing vegetation must be completed within 90 days following the removal or clearing, unless otherwise approved by the planning director. " Ordinance - 15
