Assisting the conversion of riparian zones from deciduous to coniferous or mixed forest will improve the long-term Gsh and terrestrial habitat of these streams. While riparian corridors are currently providing needed ecological functions, most of these stands are dominated by red alder. Red alder is a relatively short-lived species and alder snags and logs decay relatively rapidly. A forest stand including conifers would have a longer -lived canopy and would provide longer -lasting woody debris to the channels. Natural regeneration of conifers within the riparian corridors is slow, and silvicultural treatments designed to encourage forest succession to conifers would eventually enhance wildlife habitat and strearn conditions. Additional coniferoua tree plantings shall be required in riparian corridors in conjunction with issuance of permits for development on sites containing these corridors when the Plamting Director determines that tha corridor can be enhanced, particularly on sites with solid stands of alder without any conifer seedlings. An enhancement plan must be reviewed and approved by the Planning Department prior to the issuance of any permits. The City encourages the voluntary enhancement of all sites. (SEPA Water, Plant and Animal, and Land and Shoreline Use Policies) 4.3.4 Mitigating impacts of Development on Wetlands The wetland mapping completed for the Subarea Plan is not sufficient for purposes of project review (since boundaries were estimated and not delineated). At the time development is proposed on a site containing wetlands, a wetland delineation and study must be completed by a biologist with expertise in wetlands in compliance with Chapter 37 of the 'Zoning Code. Wetlands can change over time and incomplete wetland assessment data is available on some wetlands. When a project is proposed on a specific site, the wetland assessment(s) for the site must be updated/completed as part of the wetland delineationtstudy, using the Wetland and Buffer Functions Semi-Quantitativo Assessment Methodology. (SEPA Land and Shoreline Use, Water, and Plant and Animal Policies) 2. Wetlands must be retained and buffers must be provided per the requirements of Chapter 37, or mitigation must occur. Where the applicant proposes alteration of the wetland or buffer, additional studies must be completed and the alterations must be approved by the Planning Director. The following wetland mitigation strategy will supersede the requirements of the Toning Codc: a. Wetlands that should be preserved and protected include: • Habitat Function (croup 1 wetlands larger than 1 acre. • Wetlands located in a riparian corridor or wildlife corridor. • Wetlands that drain into an adjacent habitat Function Group 1 wetland (such as Narbeck or Kasch Swamps) or regionally rare wetland types such as Kasch Bog. • Wetlands with unique plant or animal species present. • Wetlands located in significant groundwater recharge areas. ty Zs
