(a) All refuse, toxic materials and any fill that limits or decreases the capacity of the conservation setback area to filter pollutants from runoff that flows across the conservation setback area shall be removed (not including stormwater collected and discharged from impervious surfaces). In their application materials, the applicant acknowledges and states that any refuse or toxic materials found during construction will be removed. All required fill material for the street construction will be kept to a minimum. A stormwater treatment facility is proposed along the eastern side of the street and is considered an area of fill within the conservation easement. As indicated in the applicant's written narrative, the stormwater treatment facility will filter various pollutants that flow across it and will enhance the setback area and is consistent with this standard. (b) Where practicable, finished grades shall encourage sheet flow of runoff across conservation setback areas to maximize filtering and infiltration of precipitation and runoff within conservation setback areas (not including stormwater collected and discharged from impervious surfaces). The applicant states and site plans show that finished grades will intentionally direct runoff from the conservation setback area as sheet flow into a swale on the northeast side of Randy Lane (See applicant's Sheet ST3.0). Also, as noted by the applicant, the conservation area sits at a higher elevation and runoff naturally flows downhill into the swale. The swale is designed to enhance pollutant filtration and promote infiltration more effectively than the current sheet flow conditions and is consistent with this standard. Staff review of the applicant's analysis finds their proposal to be consistent with this standard. (c) On sites where the slope within the conservation setback area exceeds 15 percent, measures (e.g., planting and contouring) shall be taken to slow the flow of runoff to the maximum extent practicable (not including stormwater collected and discharged from impervious surfaces). In this case, the stormwater treatment facility is designed to intercept and collect existing runoff. As designed, the gradual slopes of the stormwater treatment facility and vegetative plantings will slow the flow of the runoff, enhancing opportunities for infiltration and pollutant removal. Based on the applicant's proposal, their design is consistent with this standard. (d) Non-native plants shall be permanently removed to the maximum extent practicable and replaced with native plant species in accordance with subsection (3) below. The applicant notes that the area within the extent of the construction will be cleared of vegetation. As discussed in more detail in subsection (3) below and incorporated herein by reference, all areas impacted by this construction will be revegetated with native plant species, consistent with this standard.
