(b) The original soil types and configuration shall be replicated.
(c) The wetland, including buffer areas, shall be replanted with native vegetation which replicates the original species, sizes and densities.
(d) The original functional values shall be restored, including water quality and wildlife habitat functions.
(e) Required replacement ratios are shown in the following table:
Wetland In-Kind (On-Site) Restoration:
Wetland Area Created : Wetland Area Lost
4 : 1
Category II or III
2 : 1
1.25 : 1
(2) A restoration plan shall be prepared and approved prior to commencement of restoration work. Such a plan shall be prepared by a qualified wetland biologist and shall describe how the proposed actions meet the minimum requirements described in subsection (1) of this section. The City Planner shall, at the applicant’s or violator’s expense, seek expert advice in determining the adequacy of the plan. Inadequate plans shall be returned to the applicant or violator for revision and resubmittal. [Ord. 3911 § 2, 2009; Code 1970 § 28.16.120.]
