Ordinance 2859-05 - Laserfiche WebLink

This regulation applies when the restoration credits are less than the impact debits and the calculated "Acreage of Compensation"will not be less than the acreage loss; otherwise regulation 35.B.2 should be applied. The 1.25 multiplier is included in this ratio calculation to compensate for the temporal loss of wetland functions at the impact site during the time required for the functions at the compensation site to approach the"pre- impact" level of performance. 3b. How Compensation is Calculated When Regulations 35.B. 2 and 8 are Met. In cases where the performance standards established for"year 5" have been met (see 35.B.9), the acreage of compensation shall be calculated from the IVA function performance scores using the following ratio, provided that the minimum compensation requirement of regulation 35.B.2 is met: IVA score for per acre function lost X (acres lost) =Acreage of Compensation IVA score for per acre function gained This regulation is intended to provide incentive to developers for the creation of large wetland compensation banks. The 1.25 "temporal"multiplier is not included in this ratio calculation because the compensation site has demonstrated through monitoring (Regulation 35.B.8) that wetland functions are performing as proposed in the compensatory mitigation plan. 4. Compensation is Based on Limiting Function. Under Regulations 35.B. 3.a and 3b, the acreage needed for compensation shall be calculated separately for the Water Quality Improvement and Habitat groups of functions. Whichever group of functions requires the greater acreage for compensation (i.e. which is the limiting group of functionsl) shall determine the required "overall compensation acreage2" in order to ensure that the limiting function is adequately compensated for. Excess compensation acreage3 for the non-limiting function shall not be available as compensation for other wetland impacts. 5. When to Use Average Restoration Potential Per Acre. An average restoration potential per acre shall be used to establish the compensation requirements in cases where several wetland complexes are restored simultaneously(as in a compensation bank). This average is to be calculated by summing the potential increase in IVA acre-points for each group of functions and dividing by the total acreage of the site. This average shall then be used to determine the acres of compensation required according to regulations 35.B. 2 or 3. t The"limiting group of functions"shall be defined as that group of functions(e.g.Water Quality Improvement or Habitat)which exhibits the least average increase in IVA score per acre for a particular restoration site. 2"Overall Compensation Acreage"shall be defined as the required acreage of compensation calculated from regulation G.3 for the limiting group of functions(e.g.either Water Quality Improvement or Habitat). 3"Excess Compensation Acreage" is when the calculated acreage of compensation for the"non-limiting"group of functions is subtracted from the"Overall Compensation Acreage." 40
