Ordinance 2213-97 - Laserfiche WebLink

• Improve the habitat within the lower section of Merrill and Ring Creek by the addition of woody debris to the channel to create large pools and by importing scarce spawning gravels to this reach. In addition, evaluate anadromous fish access and improve, if appropriate. • Provide mitigation credit for the purchase and long term protection of headwater areas that would otherwise be developed. If the headwaters continue to be protected, Glenwood Creek is likely to maintain its trout population. • Implement KCM's recommendations for habitat improvement for Pigeon Creek#2 within Howarth Park. These recommendations call for stream restoration, including creating a more sinuous channel and more pool habitat within the park as well as bank revegetation in specific locations. These improvements, along with initial stocking of salmonids and improvement of access, could create a small salmonid fishery in this stream. (SEPA Plant and Animal and Land and Shoreline Use Policies) 4.3.4 Mitigating Impacts of Development on Wetlands 1. 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 delineation/study, using the Wetland and Buffer Functions Semi-Quantitative 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 Zoning Code: a. Wetlands that should be preserved and protected include: • Habitat Function Group 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. If fill/alteration of these wetlands is proposed, the mitigation sequencing preference order found in Section 37.110 of the Zoning Code shall be followed. Avoiding impacts is preferred, especially in areas where habitats are rare, sensitive, or critical for key species of wildlife and where wetlands perform functions that are needed or limited in a drainage basin. Avoidance is perhaps most important in bogs and in forested wetlands. Surfacewater storage is a function that is limited in the southern half of the SW Everett Subarea.
