sensitive area and wildlife habitat. Viewing platforms shall be placed landward of the wetland or stream edge. f. Wildlife. Trails should be designed and constructed to encourage users to remain on the trail through the use of fencing, signage, landscaping or other appropriate means to minimize impacts to wildlife and habitat. In addition to the requirements related to wildlife corridors elsewhere in the SMC, trail location, lighting, construction decisions, and requirements for use (e.g., pet leash requirements, bicycle speed limits, etc. should be guided by recommendations from sensitive areas studies to avoid, minimize and mitigate impacts to habitat for sensitive species. In a vegetation management plan developed for City review and approval consistent with SDC 21.03.020Q., all disturbed areas shall be landscaped with appropriate native vegetation upon completion of trail construction or as soon thereafter as possible. The trail maintenance entity shall ensure that such vegetation survives through an appropriate mechanism. An integrated vegetation and pest management plan shall be developed by the applicant and approved by the department that avoids or minimizes the use of pesticides, herbicides and other hazardous substances. g. Surfacing. To promote infiltration and groundwater recharge and to minimize slope instability, trail surfaces shall be made of pervious materials. Public multi-use trails, or other trails determined by the department to require impervious surfaces, may be paved; however, pervious paving or other low-impact techniques that meet overall project goals for cost and durability are
encouraged. Boardwalks may be used for areas subject to regular inundation, and should be constructed with nonhazardous materials. Impervious materials may also be used if necessary for soil stabilization or to prevent soil erosion, or if the trail is specifically designed and intended to be accessible to physically challenged persons and is identified as such in an adopted city comprehensive plan, parks plan or trails plan.
3. Trail corridors – Maintenance of trail corridors/ improvements
