Resolution 6712 - Laserfiche WebLink

between these water bodies and the lake will be maintained, and the degraded buffer will be restored (Exhibit 7). Public Works has noted that the condition of the corrugated metal pipe at the south end of the property should be evaluated to ensure it will have adequate life span and not be a near term maintenance expense for purchasers of homes in the development. See recommended condition no. 9. 7. All developments shall mitigate impacts to water quality using best available science. Compliance with City stormwater regulations consistent with the state stormwater regulations shall be required. Water quality monitoring during construction and operation may be required by the Planning and Community Development Director or Hearing Examiner on a project by project basis based upon specific characteristics of the proposal. Staff Comment: Final stormwater design will need to comply with the City's adopted stormwater manual. See recommended condition No. 11. 17. Where buffers are restored or enhanced, plantings shall generally be spaced and composed to mimic native buffer communities. However, plantings shall also be designed to take into account impacts to views and scenic vistas. Measures to protect views and scenic vistas may include, but are not limited to: grouping large trees in clusters; selecting species that grow to heights that allow views without requiring maintenance pruning; clustering evergreens. 18. When public access is incorporated into buffers, buffer plantings shall be preserved and/or restored to the extent practicable. However improvements such as, paved trails, non-motorized public access bridge structures, overlooks, limited grassy recreational areas, and limited areas of hardened surfaces for direct access to the water may be permitted. 19.All plantings within environmentally sensitive areas and their required buffers shall be native species or native-hybrids. The City shall encourage developers to use native species for all landscaping within 100 feet of the shoreline, except for areas permitted for grass in conjunction with public access, recreational developments, or dike maintenance. 21. Buffers shall be maintained to eliminate non-native species when practicable. Assurance devices shall be required for restored and enhanced buffers. Staff Comment: A soft trail is proposed to be located within portions of the restored wetland and stream buffers. The site is severely disturbed, there is minimal buffer vegetation to be preserved. The applicant proposes restoration of the buffer as shown in Exhibit 7. 26. Stormwater facilities are prohibited in Category 1 stream and wetland buffers. In lower rated wetlands and streams, stormwater management facilities are permitted only within the outer twenty-five percent (25%) of the buffer, provided that: i. The buffer area has been previously substantially and legally altered and is degraded as defined by PDI 01-005. ii. Native vegetation and soils at the site should be protected and low impact development techniques should be used to promote infiltration of stormwater at the 6
