Enhancement is undertaken for specified purposes such as water quality <br /> improvement, flood water retention or habitat. Activities typically consist of planting vegetation, <br /> influence hydroperiods,or some combination of these. Enhancement results in a change in some wetland <br /> functions and can lead to a decline in other wetland functions, but does not result in a gain in wetland <br /> acres. <br /> Table 37.4:Standard Wetland Compensation Ratios <br /> Category and Type Re-establishment Rehabilitation Re-establishment Re-establishment Enhancement <br /> of Wetland or Creation Only4 or Creation(R/C) or Creation(R/C) Only' <br /> Impacts and Rehabilitation and Enhancement <br /> (RH)4 (E)4 <br /> All Category IV 1.5:1 3:1 1:1 R/C and 1:1RH 1:1 R/C and 2:1 E 6:1 <br /> All Category III 2:1 4:1 1:1 R/C and 2:1 RH 1:1 R/C and 4:1 E 8:1 <br /> Category II Case-by-case 4:1 Case-by-case Case-by-case Case-by-case <br /> Estuarine Rehabilitation of <br /> an estuarine <br /> All other Category 3:1 6:1 1:1 R/C and 4:1 RH 1:1 R/C and 8:1 E 12:1 <br /> Category I 6:1 12:1 1:1 R/C and 10:1 1:1 R/C and 20:1 E 24:1 <br /> Forested RH <br /> Category I based 4:1 8:1 1:1 R/C and 6:1 RH 1:1 R/C and 12:1 E 16:1 <br /> on score for <br /> functions <br /> Category I Bog Not considered 6:1 R/C Not R/C Not Case-by-case <br /> possible6 Rehabilitation of a considered considered <br /> bog possible& possible& <br /> Category I Case-by-case 6:1 Case-by-case Case-by-case Case-by-case <br /> Estuarine Rehabilitation of <br /> an estuarine <br /> NOTE: Preservation is discussed in the following section. <br /> Creation=The manipulation of the physical, chemical, or biological characteristics present to develop a wetland on <br /> an upland or deepwater site, where a wetland did not previously exist. Activities typically involve excavation of <br /> upland soils to elevation that will produce a wetland hydroperiod, create hydric soils, and support the growth of <br /> hydrophytic plant species. Establishment results in a gain in wetland acres. <br /> Planning Commission Resolution 19-04 Page 41 <br /> Critical Areas March 19, 2019 <br />
