Lonnie and Lara, At your request and consistent with our agreed scope -of -work dated 10/17/2019, I performed a Level TI wetlan delineation arld fun t c nal_.assessnaent for parcel # 002342039 located adjacent to Old School House Road, NW 1/4 of the NW1/4, Section 34, Township 30 North, Range 02 West, Willamette Meridian, Jefferson County, Washington (Figure 1). The subject parcel is bounded on the west by Old School House Road and by Gardiner Beach Road to the north. An abandoned railroad alignment runs diagonally along the eastern property boundary. The parcel is bounded to the south by parcel 002342037. The area of parcel 002342039 is listed as 4.56 acres by the Jefferson County Assessor Office records. The parcel is generally gently sloping 0-5% to the east and is dominated by eme ent ve atian, primarily species used for historic hay production (Figure 2).� Three human -created ponded areas (e.g. ponds) connected by a ditch system exist along the. eastern parcel boundary. These ponds appear to have been created sometime between 1990 and 2005 based on aerial photograph review. I visited the site on July 7, 2019 and again on March 18, 2020, and walked the parcel boundaries and adjacent areas. I excavated shallow soil pits to 16 inches to evaluate soil color, texture, and shallow groundwater characteristics and recorded vegetation communities consistent with methodology published by the Washington Department of Ecology Washington State Wetlands Identification and Delineation Manual (Ecology, 1997) and the U.S. Army Corps of Engineers Western Valleys and Mountains Regional Supplement to the Federal Wetland Delineation Manual adopted by Jefferson County. I collected vegetation, soils, and hydrology data in four plots, two plots located within suspected wetland areas and two plots located in apparent upland areas. Plot locations are shown on Figure 14 and Plot Data Forms are included in Appendix A. Additionally, prior to visiting the site I reviewed the following information: 1. Aerial photographs from 1955,1990, 2003, 2005, 2006, 2009, 2011,2013, 2015, 2017 2. National Wetlands Inventory Mapping (NWI, USFWS 2019). 2 Crescent Environmental PLLC 3. NRCS On-line soil survey (MRCS, 2019) 4. Jefferson County Critical Areas On -Line Mapping. 5. Wetland Delineation prepared in 2005 by Loggy Soil and Wetland Consulting for the parcel adjacent to the south (002342037). 6. Wetland Determination Letter from Aquatic Environmental Services for parcel 002331035 adjacent to the west of the subject parcel. Aerial photographs (Figures 5-13) indicate the likely presence of two seasonally saturated areas dominated by emergent vegetation on the parcel and three areas of ponded water along the eastern parcel boundary. The National Wetlands Inventory Mapping (not shown) shows no wetland areas on the subject parcel. Jefferson County Critical Areas Mapping shows a wetland area occupying the central portion of the subject parcel. Jefferson County wetland mapping appears to follow ft-NRCSsail mapping polygon for the Belfast§Dkuniva than an actual wetl . Aquatic Environmental ervi s came to�the same conclusion when assessing the adjacent parcel (002331025) in 2003 (Figure 2) The NRCS On -Line Soil Survey indicates the parcel soils are mapped as Belfast silty clay loam, wet variant, a hydric soil, and Clallam gravelly sandy loam (non-hydric) (Figure 3). On -Site Observations The majority of the subject parcel vegetation is dominated by emergent plants consisting primarily of grass and alfalfa species used in the production of hay. Additional emergent wetland species such as Juncus effusus (Common rush) and Ranunculus repens (Creeping buttercup) are found in wetland areas. Both introduced non-native and native scrub species and ornamental tree species are located adjacent to the property boundaries and associated with the pond and ditch drainage system on the eastern margin of the parcel. Due to the historic management of this parcel for hay production, the vegetation community would be considered "disturbed" for the purposes of wetland delineation. The site topography is undulating, consisting of a series of subtle concave swales alternating with convex ridges. Seasonally shallow groundwater was observed within the concave swale areas and is apparent from the darker green color observed in these areas on historic aerial photography. Concave ridge areas displayed upland characteristics and are observed to have dry soil profiles and are dominated by upland vegetation communities as demonstrated by the data collected at Plot locations 1-4 (Appendix A). Crescent Environmental PLLC 3 Plot 1 (South Wetland) Plot 1 is located in the South Wetland (2.04 acres) (Figure 14). The plant community is dominated by emergent vegetation consisting of Creeping bentgrass (Agrostis stolonifera) Creeping buttercup (Ranunuculus repens) and Soft rush (Juncus effusus). Soils at Plot 1 consisted of Grayish Brown (IOYR 5/2) gravelly silt loam, with Yellow Red (5 YR 5/6) redox masses. The soil profile at Plot 1 was saturated to the surface on March 18, 2020. All three wetland parameters (plants, soils and hydrology) are satisfied at Plot 1. Plot 2 (Upland) Plot 2 is located in the center of the parcel (Figure 14) on a convex surface. Dominant vegetation observed at Plot 2 consisted of Orchard grass (Dactylis glomerata), English plantain (Plantago lanceolata) and Spotted Cats Ear (Hypochaeris radicata). Soils at Plot 2 consisted of Brown (IOYR 4/3) to Pale Brown (IOYR 6/3) gravelly to very gravelly sandy loam. The soil profile at Plot 2 was dry to a depth of 16 inches. No saturation or water table was observed at Plot 2. Site conditions observed at Plot 2 indicate the absence of any wetland parameters. Plot 3 (North Wetland) Plot 3 is located in the North wetland area (0.46 acres). The dominant vegetation observed at Plot 3 consisted of Creeping bentgrass (Agrostris stolonifera), Creeping buttercup (Ranunculus repens) and Soft rush (Juncus effusus). Soils at Plot 3 while mapped by the NRCS as Clallam Very Gravelly Sandy loam consisted of Very Dark Greyish Brown (10YR 3/2) Palix silt loam. Surface water approximately 1" deep was observed at Plot 3 on March 18, 2020. All three wetland parameters were satisfied at Plot 3. Crescent Environmental PLLC 4 Plot 4 (Upland) Plot 4 is located on the north side of the parcel on a convex ridge. Dominant vegetation observed at Plot 4 consisted of Orchard grass (Dactylis glomerata), English Plantain (Plantago lanceolata) and Spotted Cats Ear (Hypochaeris radicata). Soils observed at Plot 4 consisted of Dark Yellowish Brown (10YR 5/6) very gravelly sandy loam to a depth of 16". No saturation or elevated water table was observed at Plot 4. Plot 4 meets the technical criteria for an upland site. Due to the agriculturally disturbed nature of the vegetation community, it is my opinion that the plant community in the wetland areas is not representative of the hydric conditions demonstrated in the observed Plot data. If site disturbance from hay production is stopped, native wetland plants are likely to re-establish within the wetland areas. Planting native wetland plant species within the mapped wetland areas will act to accelerate the natural recovery of these heavily impacted wetland sites and will help improve the functional quality of the site. Based on my on -site investigation of plants, soils and hydrology within the parcel boundaries, I delineated two wetland areas on the parcel: a 0.47-acre wetland in the northern portion of the parcel and a 2.04-acre wetland in the southern portion of the parcel. Each of these wetlands are classified as palustrine, emergent, seasonally saturated wetlands, based on the presence of hydrophytic vegetation, hydric soils, and observations of shallow surface inundation and/or saturation of the soil profile in the upper 16 inches (Figure 14). Wetland boundaries were staked and flagged in the field and locations mapped using an Arrow Gold real-time kinematic global positioning system (RTK-GPS) connected to the Washington State Reference Network (WSRN) to access real-time positioning corrections. Wetland boundaries were mapped in two-dimensional (x, y) space using U.S. Feet in the NAD83 datum using the State Plane Washington North projection with an accuracy of approximately +/- 5 cm Root Mean Square Error (RMSE). The wetland boundaries are staked approximately every 50 feet with 4-foot tall surveyor stakes and pink flagging. The associated wetland buffers are staked approximately every 50 feet with 4- foot tall 2" x 2" treated stakes with orange flagging. The upland area which includes a portion of the created pond on the east side of the parcel is 1.37 acres. (Figure 14). Crescent Environmental PLLC 5 Wetland Functional Assessment Wetlands delineated on the parcel were evaluated using the methods published by the Washington Department of Ecology (WDOE, 2015) "Washington State Wetland Rating System for Western Washington". The assessment forms are presented in Appendix B. Based on this functional assessment, the wetlands present on the parcel would be designated as Class IV wetlands based on function. Wetland Classification The seasonally inundated, palustrine, emergent wetlands identified on the parcel are typed as Class 4 wetlands by Jefferson County Code 18.22.300. The landscape classification of the wetlands on the parcel would be Class IV because they are less than 20 acres in size and do not satisfy the criteria for Class I, II, or III criteria. The protection standards for regulated wetlands designated by Jefferson County Code 18.22.330 would be 40 feet for a Class IV wetland for the purposes of single family development. The wetland boundary is marked in the field with four -foot tall wooden survey stakes with pink flagging, and the wetland buffer is marked with survey stakes and orange flagging. Plot locations are marked in the field with un-flagged surveyor stakes labelled with plot numbers. Figure 15 shows the implementation of wetland buffer averaging in order to reduce the buffer width to 20 feet on the north side of the south wetland. Additional buffer area has been added to the east side of the north and south wetlands. Buffer averaging achieves a net increase of wetland buffer area of 0.08 acres. Upland Classification Areas not mapped as wetland in Figure 14 are classified as upland sites. An area approximately 1.37 acres in size in the central portion of the subject parcel is classified as Upland (Figure 14). SUMMARY Remote review of historic aerial photography and wetland reports from adjacent parcels along with on -site investigation of the subject parcel for the purposes of wetland delineation indicates there are two regulatory wetlands within the parcel boundaries. These wetlands by definition in the Jefferson County Critical Areas Code should have a 40-foot buffer designated from the edge of the wetlands. Figure 14 shows the wetland areas with associated 40-foot wetland buffers. 6 Crescent Environmental PLLC It is proposed to reduce the buffer width along the north side of southern wetland to 20 feet through buffer averaging. Additional buffer area is applied to the east sides of the northern and southern wetlands which will achieve a net increase in buffer area by 0.08 acres. On -site investigation determined that the vegetation community, soils and hydrology on the subject parcel do meet the criteria for wetland characteristics published by the Washington Department of Ecology Washington State Wetlands Identification and Delineation Manual (Ecology, 1997) and the U.S. Army Corps of Engineers, Western Valleys and Mountains Regional Supplement to the Federal Wetland Delineation Manual adopted by Jefferson County. No other wetland areas were observed on the subject parcel other than the areas identified on Figure 14.

Wetlands 18.22.290 Stewardship alternative. Article VII sets forth the prescriptive requirements for wetlands. Applicants for development permits or approvals subject to this article may elect to comply with the critical area stewardship plan (CASP) provisions set forth in Article IX of this chapter in lieu of the prescriptive requirements set forth herein. CASP may be applied within Category II, III, and IV wetlands and buffers, and within buffers in Category I. They cannot be used in Category I wetlands. [Ord. 3-08 § 1] 18.22.300 Classification/designation. (1) Classification. Wetlands shall be classified using the 2004 Washington State Department of Ecology's Wetland Rating System for Western Washington (Ecology Publication No. 04-06- 025), or as amended. Wetland rating categories shall not be determined based upon illegal modification of the land. Wetland delineations shall be determined by using the Washington State Wetlands Identification and Delineation Manual, March 1997, or as amended hereafter. (2) Designation. As determined using the 1997 Washington State Department of Ecology's Washington State Wetlands Identification and Delineation Manual (Ecology Publication No. 96- 94 or as amended), wetlands shall be designated as critical areas and regulated under this article regardless of size; provided, that Category IV wetlands less than one -tenth acre (4,356 square feet) shall be exempt from the requirements of this article when all of the following criteria are met: (a) The wetland does not provide breeding habitat for native amphibian species. Breeding habitat is indicated by adequate and stable seasonal inundation, presence of thin -stemmed emergent vegetation, and clean water; (b) The wetland does not have unique characteristics that would be difficult to replace through standard compensatory mitigation practices; (c) The wetland is not located within a fish and wildlife habitat conservation area (FWHCA) as defined in the section of this chapter dealing with FWHCAs, and is not integral to the maintenance of habitat functions of an FWHCA; (d) The wetland is not located within a floodplain; (e) The wetland is not associated with a shoreline of the state as defined by the county's shoreline master program; (f) The wetland is not part of a mosaic of wetlands and uplands, as determined using the Crescent Environmental PLLC 52 guidance provided in the wetland rating system. (3) Sources Used for Identification. The following sources should be used to identify potential wetland locations. Sources include, but are not limited to: (a) United States Department of the Interior, Fish and Wildlife Service, National Wetlands Inventory. (b) United States Department of Agriculture, Soil Conservation Service, Soil Survey of Jefferson County Areas, Washington. (c) United States Department of Agriculture, Natural Resources Conservation Service, Hydric Soils List, Jefferson County Area. (d) County critical areas mapping. The wetland maps prepared by the county have been produced for informational purposes only and are not regulatory devices forming an integral part of this article. [Ord. 3-08 § 1] 18.22.310 Regulated activities. Any land use or development activity shall be subject to the provisions of this Article VII, including, but not limited to, the following activities that are directly undertaken or originate in a regulated wetland or its buffer, unless exempted under JCC 18.22.070: (1) The removal, excavation, grading, or dredging of material of any kind, including the construction of ponds and trails; (2) The dumping or discharging of any material, or placement of any fill; (3) The draining, flooding, or disturbing of the wetland water level or water table; (4) The driving of pilings; (5) The placing of obstructions; (6) The construction, reconstruction, demolition, or expansion of any structure; (7) The destruction or alteration of wetland vegetation through clearing, harvesting, shading, intentional burning, application of herbicides or pesticides, or planting of vegetation that would alter the character of a regulated wetland; provided, that these activities are not part of a forest practice governed under Chapter 76.09 RCW (Forest Practices Act) and its rules; (8) Activities that result in: (a) A significant change of water temperature; Crescent Environmental PLLC 53 (b) A significant change of physical or chemical characteristics of wetlands water sources, including quantity; or (c) The introduction of pollutants; or (9) Wetland Buffers. In addition to those activities allowed in regulated wetlands in this article, the following activities are allowed within wetland buffers without having to meet the protection standards or requirements for wetland studies or mitigation, set forth in this article; provided, that impacts to buffers are minimized and that disturbed areas are immediately restored except as specifically allowed in JCC 18.22.070. (a) Activities having minimal adverse impacts on buffers and no adverse impacts on regulated wetlands. These include low intensity, passive recreational activities, such as pervious trails, nonpermanent wildlife watching blinds, scientific or educational activities, and sports fishing or hunting. Trails within buffers shall be designed to minimize impacts to the wetland, and shall not include any impervious surfaces. (b) Within the buffers of Category III and IV wetlands only, vegetation -lined swales designed for storm water management or conveyance when topographic restraints determine there are no other upland alternative locations. Swales used for detention purposes may only be placed in the outer 25 percent of the buffer. Conveyance swales may be placed through the buffer, if necessary. [Ord. 3-08 § 1] 18.22.330 Protection standards. (1) General. Application for a project on a parcel of real property containing a designated wetland or its buffer shall adhere to the requirements set forth below. (2) Delineation. An applicant submitting a project application shall also submit, and have approved, a wetland delineation report as specified in JCC 18.22.450. Additionally, the following provisions shall apply: (a) The location of the wetland and its boundary shall be determined through the performance of a field investigation utilizing the methodology contained in the Washington State Wetlands Identification and Delineation Manual, March 1997, or as amended hereafter. (b) If the wetland is located off of the property involved in the project application and is inaccessible, the best available information shall be used to determine the wetland boundary and category. (c) The wetland boundary shall be staked or flagged in the field. (d) This requirement may be waived under the following circumstances: (i) Single -Family Residences. The requirement for a wetland delineation and special report may be waived by the administrator for construction of a single-family residence on an existing lot of Crescent Environmental PLLC 54 record if DCD staff or a qualified wetland evaluator determines that: (A) Sufficient information exists for staff to estimate the boundaries of a wetland without a delineation; and (B) The single-family residence and all accessory structures and uses are not proposed to be located within the distances identified in Table 18.22.330(1) from the estimated wetland boundary. "Qualified wetland evaluator" means an individual recognized and acceptable to the administrator in using the most current edition of the Department of Ecology's Washington State Wetland Rating System for Western Washington (2004), Ecology Publication No. 04-06-025, or as amended, in categorizing and rating wetlands. (ii) Subdivisions and Short Subdivisions. The requirement for a wetland delineation and special report will be waived for subdivisions and short subdivisions of an existing lot of record if a site assessment made by a qualified wetland evaluator indicates the following: (A) Sufficient information exists to estimate the boundaries of a wetland without a delineation; and (B) Building envelopes or building setback lines are not proposed to be located within the distances identified in Tables 18.22.330(1), (2) and (3) from the estimated wetland boundary. (3) Wetland Buffer Requirements. Wetland buffer widths shall be prescribed and established based upon the category of the wetland, the wetland rating scores and the impact level of the proposed land use. The resulting buffers are shown in Tables 18.22.330(1), (2), and (3) (for low, moderate and high impact land uses). (a) The category and rating scores of a wetland shall be determined by a qualified wetland evaluator who must be recognized and acceptable to the administrator and use the most current edition of the Department of Ecology's "Wetlands in Washington State Volume 2: Guidance for Protecting and Managing Wetlands" (DOE Publication No. 05-06-0008) in categorizing and rating wetlands. (b) There are three land use impact level types. Each type is presented with the table containing the buffer widths that would be prescribed for its associated wetland category. (c) Proposals for development will have three options for deciding what their buffer distance will be. A buffer distance is the closest distance the proposed development can be to the wetland boundary. (i) The stewardship plan option, as detailed in Article IX of this chapter. (ii) The Professionally Delineated Boundary Option. A prescriptive buffer distance based on an actual delineation of the wetland boundary as determined by a qualified wetland evaluator (cost Crescent Environmental PLLC 55 is the responsibility of proponent). This buffer distance will be measured outward from the delineated wetland boundary. Refer to the column in the tables with the word "delineation" in the heading. (iii) The Apparent Boundary Option. A prescriptive buffer distance based on the apparent location of the wetland boundary as proposed by the county's wetland specialist. In these cases the buffer will be the total distance calculated using the buffer distance as shown in the "delineation" column of the tables plus an additional 20 to 50 feet, depending upon wetland category (shown in the "nondelineation" column of the table). This calculated buffer distance will be measured outward from the apparent wetland boundary. (4) Drainage and Erosion Control. An applicant submitting a project application shall also submit, and have approved, a drainage and erosion control plan as specified in this chapter. The plan shall discuss, evaluate and recommend methods to minimize sedimentation of designated wetlands during and after construction. (5) Buffer Marking. Upon approval of the delineation report, the location of the outer extent of the wetland buffer shall be marked in the field as follows: (a) A permanent physical indicator along the upland boundary of the wetland buffer area shall be installed and permanently maintained. (b) During construction activities, buffer perimeters shall be marked with temporary signs at an interval of one per parcel or every 100 feet, whichever is less. Signs shall remain in place prior to and during approved construction activities. The signs shall contain the following statement: "Wetland & Buffer — Do Not Remove or Alter Existing Native Vegetation." (c) In the case of short plat, long plat, binding site plan, and site plan approvals under this code, the applicant shall include on the face of any such instrument the boundary of the wetland and its buffer. (d) The applicant may also choose to dedicate the buffer through a conservation easement or deed restriction that shall be recorded with the Jefferson County auditor. Such easements or restrictions shall, however, use the forms approved by the prosecuting attorney. (6) Buffers — Standard Requirements. (a) The administrator shall have the authority to require buffers from the boundaries of all wetlands as established by this article, and in accordance with the following criteria. (i) Wetland buffer widths shall be measured along a horizontal line perpendicular to the wetland boundary as marked in the field during delineation if required, or based upon site investigation, aerial photographs, or LiDAR images. (ii) Functionally isolated buffer areas are those areas separated from a wetland that do not protect the wetland from adverse impacts. Buffers need not include areas that are functionally isolated Crescent Environmental PLLC 56 and physically disconnected from the wetland by a substantial developed surface such as a dike, building, parking lot, or road. In determining whether or not a buffer area is functionally isolated, the administrator shall take into consideration whether or not the isolated buffer area is used by wildlife to gain access to the wetland. In instances where substantial wildlife use is documented, the area shall be retained as buffer despite being otherwise isolated or disconnected from the wetland. (iii) When a buffer is on a slope steeper than 40 percent, and/or lacks adequately dense and diverse vegetation, the administrator may deny a proposal for buffer reduction or buffer averaging. (b) The prescribed buffer widths shall be established on the basis of the following factors: (i) The wetland's value and sensitivity to disturbance, based on its category (I, II, III, IV) as determined by the total score on the rating form for the wetland rating system; (ii) The expected level of impact of the proposed adjacent land use, as determined from Tables 18.22.330(1), (2), and (3). The administrator may determine, on the basis of detailed information from the applicant about the site conditions, scope, and intensity of the proposed development, that the proposed land use will have a lesser level of impact on the wetland than indicated by similar land uses on the list.

All applications for Type 1 noncompensatory enhancement projects shall be accompanied by an enhancement plan prepared in accordance with subsections (1)(a) and (1)(b) of this section, which demonstrates that the proposed activities will result in an increase in wetland functions and values. (a) The enhancement plan must be submitted for review, and approved by the administrator. (b) The enhancement plan must either be prepared by a qualified wetlands consultant or accepted in writing by the U.S. Fish and Wildlife Service, the Washington Department of Fish and Wildlife, or the Washington Department of Ecology. (2) Type 2 Noncompensatory Enhancement. Type 2 noncompensatory enhancement projects involve wetland alterations that do not include the filling, draining, or excavating of a regulated wetland. Such projects might involve the removal of nonnative plant species or the planting of native plant species. All applications for Type 2 noncompensatory enhancement projects shall be accompanied by an enhancement plan prepared in accordance with subsections (2)(a) through (2)(c) of this section, which demonstrates that the proposed activities will result in an increase in wetland functions and values. (a) The enhancement plan shall be submitted for review, and approved, by the administrator. (b) The enhancement plan must include a detailed description of the activity including the following information: (i) The goal of the enhancement project; (ii) What plants, if any, will be removed or planted; (iii) How the activity will be conducted, including the type(s) of tools or machinery to be used; and (iv) The qualifications of the individual who will be conducting the enhancement activity. (c) The enhancement plan must either be prepared by a qualified wetlands consultant or accepted in writing by the U.S. Fish and Wildlife Service, the Washington Department of Fish and Wildlife, or the Washington Department of Ecology. [Ord. 3-08 § 1] 18.22.350 Mitigation. The overall goal of mitigation shall be no net loss of wetland function, value, and acreage. (1) Mitigation Sequence. Mitigation includes avoiding, minimizing, or compensating for adverse impacts to regulated wetlands or their buffers. When a proposed use or development activity poses potentially significant adverse impacts to a regulated wetland or its buffer, the preferred sequence of mitigation as defined below shall be followed unless the applicant demonstrates that ']O Crescent Environmental PLLC an overriding public benefit would warrant an exception to this preferred sequence. (a) Avoiding the impact altogether by not taking a certain action or parts of actions on that portion of the site which contains the regulated wetland or its buffer; (b) Minimizing impacts by limiting the degree or magnitude of the action and its implementation; (c) Rectifying the impact by repairing, rehabilitating, or restoring the affected environment; (d) Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action; or (e) Compensating for the impact by replacing, enhancing, or providing substitute resources or environments. (2) Compensatory Mitigation — General Requirements. As a condition of any permit or other approval allowing alteration which results in the loss or degradation of regulated wetlands, or as an enforcement action pursuant to Chapter 18.50 JCC, compensatory mitigation shall be required to offset impacts resulting from the actions of the applicant or any code violator. (a) Except persons exempt under this article, any person who alters or proposes to alter regulated wetlands shall restore or create areas of wetland equivalent to or larger than those altered in order to compensate for wetland losses. The following table specifies the ratios that apply to creation or restoration that is in -kind, on -site, and is accomplished prior to or concurrently with alteration: Table 18.22.350 Required Replacement Ratios for Compensatory Wetland Mitigation Category Re- Rehabilitation Re- Re- Enhancement and Type establishment Onlyl establishment establishment Onlyl of or Creation or Creation or Creation Wetland (R/C) and (R/C) and Impacts Rehabilitation Enhancement (RH)1 (E)l All 1.5:1 : l 1:1 R/C and 1:1 1:1 R/C and 6:1 Category RH 2:1 E IV All 2:1 4:1 1:1 R/C and 2:1 1:1 R/C and 8:1 Category RH 4:1 E III ']1 Crescent Environmental PLLC Table 18.22.350 Required Replacement Ratios for Compensatory Wetland Mitieation Category Re- Rehabilitation Re- Re- Enhancement and Type establishment Onlyl establishment establishment Onlyl of or Creation or Creation or Creation Wetland (R/C) and (R/C) and Impacts Rehabilitation Enhancement (RH)1 (E)l Category II Case -by -case 4:1 Case -by -case Case -by -case Case -by -case Estuarine Rehabilitation of an estuarine wetland Category II 2:1 4:1 1:1 R/C and 2:1 Not considered Not considered Interdunal RH an option2 an option2 Compensation Compensation Compensation has to be has to be has interdunal interdunal to be interdunal wetland wetland wetland All Other 3:1 6:1 1:1 R/C and 4:1 1:1 R/C and 12:1 Category 11 RH 8:1 E Category I 6:1 12:1 1:1 R/C and 1:1 R/C and 24:1 Forested 10:1 RH 2O:1 E Category 1 4:1 8:1 1:1 R/C and 6:1 1:1 R/C and 16:1 Based on RH 12:1 E Score for Functions Category I Not considered 6:1 R/C not R/C not Case -by -case Natural possible3 considered considered Heritage Rehabilitation of possible3 possible3 Site a Natural Heritage site Category I Not considered 6:1 R/C not R/C not Case -by -case Coastal possible3 considered considered Lagoon Rehabilitation of possible3 possible3 a coastal lagoon Category I Not considered 6:1 R/C not R/C not Case -by -case Bog possible3 considered considered Rehabilitation of possible3 possible3 a bog %2 Crescent Environmental PLLC Table 18.22.350 Required Replacement Ratios for Compensatory Wetland Mitigation Category Re- Rehabilitation Re- Re- Enhancement and Type establishment Onlyl establishment establishment Onlyl of or Creation or Creation or Creation Wetland (R/C) and (R/C) and Impacts Rehabilitation Enhancement (RH)1 (E)l Category I Case -by -case 6:1 Case -by -case Case -by -case Case -by -case Estuarine Rehabilitation of an estuarine wetland 1 These ratios are based on the assumption that the rehabilitation or enhancement actions implemented represent the average degree of improvement possible for the site. Proposals to implement more effective rehabilitation or enhancement actions may result in a lower ratio, while less effective actions may result in higher ratio. The distinction between rehabilitation and enhancement is not clear-cut. Instead, rehabilitation and enhancement actions span a continuum. Proposals that fall within the gray area between rehabilitation and enhancement will result in a ratio that lies between the ratios for rehabilitation and the ratios for enhancement. 2 Due to the dynamic nature of interdunal systems, enhancement is not considered an ecologically appropriate action. 3 Natural heritage sites, coastal lagoons, and bogs are considered irreplaceable wetlands because they perform some functions that cannot be replaced through compensatory mitigation. Impacts to such wetlands would therefore result in a net loss of some functions no matter what kind of compensation is proposed. (b) Compensation must be completed prior to wetland destruction, where possible. (c) Compensatory mitigation must follow an approved compensatory mitigation plan pursuant to this article, with the replacement ratios as specified above. (d) Compensatory mitigation must be conducted on property that will be protected and managed to avoid further development or degradation. The applicant or code violator must provide for long-term preservation of the compensation area. (e) The applicant shall demonstrate sufficient scientific expertise, supervisory capability, and financial resources, including bonding, to carry out the project. The applicant must demonstrate the capability for monitoring the site and making corrections if the project fails to meet projected goals. Crescent Environmental PLLC 73 (f) Compensatory mitigation must monitor the impact and take appropriate corrective measures. (3) Compensatory Mitigation — Type, Location, and Timing. (a) Priority will be given to in -kind, on -site compensation if feasible and if the wetland to be lost has a moderate to high functional value. (b) When the wetland to be impacted is of a limited functional value and is degraded, compensation may be of the wetland community type most likely to succeed with the highest functional value possible. (c) Out -of -kind compensation may be allowed when out -of -kind replacement will best meet identified goals (for example, replacement of historically diminished wetland types). Where out - of -kind replacement is accepted, greater acreage replacement ratios may be required to compensate for lost functional values. (d) Off -site compensation can be allowed only if: (i) On -site compensation is not feasible due to hydrology, soils, waves, or other factors; (ii) On -site compensation is not practical due to probable adverse impacts from surrounding land uses; (iii) Potential functional values at the site of the proposed restoration are significantly greater than the lost wetland functional values; or (iv) Off -site compensation will be conducted in accordance with subsection (4) of this section (Cooperative Compensation Projects). (e) Except in the case of cooperative compensation projects, off -site compensation must occur within the same watershed where the wetland loss occurs; provided, that Category IV wetlands may be replaced outside of the watershed if there is no reasonable technical alternative. The stormwater storage function provided by Category fV wetlands must be provided for within the design of the development project. (f) Except in the case of cooperative compensation projects, in selecting compensation sites applicants must pursue locations in the following order of preference: (i) Filled, drained, or cleared sites which were formerly wetlands and where appropriate hydrology exists; and (ii) Upland sites, adjacent to wetlands, if the upland is significantly disturbed and does not contain a mature forested or shrub community of native species, and where the appropriate natural hydrology exists. (g) Construction of compensation projects must be timed to reduce impacts to existing wildlife Crescent Environmental PLLC 74 and flora. Construction must be timed to assure that grading and soil movement occurs during the dry season. Planting of vegetation must be specifically timed to the needs of the target species. (h) A mitigation plan shall include a monitoring plan. The duration, frequency and methods of monitoring depend on a project's goals, objectives, and performance standards. In general, monitoring is required for at least five years. If a scrub -shrub or forested vegetative community is proposed, monitoring may be required for 10 years or more. Monitoring may be extended if interim performance standards are not met. (4) Cooperative Compensation Projects. The county may encourage, facilitate, and approve cooperative projects where one or more applicants, or an organization with demonstrated capability, may undertake a compensation project if it is demonstrated that: (a) Creation of one or several larger wetlands may be preferable to many small wetlands; (b) The group demonstrates the organizational and fiscal capability to act cooperatively; (c) The group demonstrates that long-term management of the compensation area can and will be provided; and (d) There is a clear potential for success of the proposed compensation at the identified compensation site. Conducting compensation as part of a cooperative process does not reduce or eliminate the required replacement ratios outlined in this article. [Ord. 3-08 § 1] Article VIII. Special Reports 18.22.360 General requirements. (1) The administrator may require a special report or reports when critical areas are impacted. (2) Special reports for critical areas shall include a scale map of the development proposal site and a written report. (3) The special report shall identify and characterize any critical area as a part of the larger development proposal site, assess impacts of the development proposal on any critical area on or adjacent to the development proposal site, and assess the impacts of any alteration proposed for a critical area. (4) The special report shall propose adequate protection mechanisms that may include mitigation, maintenance and monitoring plans, and performance surety. (5) Special reports shall include documentation certifying the qualifications of the preparer. [Ord. 3-08 § 1] Crescent Environmental PLLC 75 18.22.370 Waivers. The administrator may waive the requirement for a special report when an applicant demonstrates all of the following: (1) The proposal involved will not affect the critical area in a manner contrary to the goals, purposes and objectives of this code. (2) The minimum protection standards required by this chapter are satisfied. [Ord. 3-08 § 1] 18.22.380 Retaining consultants. Jefferson County may retain consultants to assist in the review of special reports outside the range of staff expertise. The applicant shall pay for the costs of retaining said consultants. [Ord. 3-08 § 1] 18.22.390 Acceptance of special reports. (1) The administrator shall verify the accuracy and sufficiency of all special reports within 42 calendar days of their submission. (2) If the administrator finds that a special report does not accurately reflect site conditions, or does not incorporate appropriate protections mechanisms, the administrator shall cite evidence (e.g., soil samples, well log data, etc.) that demonstrates where the special report is insufficient or in error. The applicant may then either revise the special report and submit another special report, or appeal the administrative determination pursuant to this code. [Ord. 3-08 § I] 18.22.450 Wetland delineation report. (1) General. This report shall be required when a proposed development encroaches upon a designated wetland or its buffer, and shall be used to identify the boundaries and classification of the designated wetland. (2) Qualifications of the Preparer. Wetland delineation reports shall be prepared by a biologist with wetlands expertise, a professional wetland scientist certified by the Society of Wetland Scientists. (3) Information Requirements.
