H a V ADDENDUM Requirement: In 2008 the original buffer for the wetland was established for a single family home. The amount of development in 2008 qualified as a moderate impact land use requiring a 60 foot buffer. The proposed addition of a meadery (honey wine) Cottage Industry Conditional Discretionary use to the two parcels with a new septic system requires as review of the wetland area and reclassification of the wetland. The reasons for the review and re-classification of the wetland are that the wetland study is outdated and a new wetland classification was adopted on January 1, 2014. Although the meadery is considered a commercial venture and closely aligned with the high impact land use it is considered as moderate impact land use.' ' Email for Donna Frostholm, Assistant Planner, Jefferson County Department of Community Development, January25, 2016, 9:41 AM. Reeter 999008303 LSWC Page 3 Page 14 Pre-ExistinE The wetland study on the parcel 99908303 was completed on July 20, Inventories: 2007 and submitted by Mr. Mrs. Reeter to the Jefferson County Department of Community County on September 24, 2008. This wetland report is outdated mainly due to changes in Jefferson County Code (JCC) 18.22.330 (1) (2) (3) wetland buffer requirements and Washington State Department of Ecology updated wetland rating system in 2014 and effective on January 1, 2015. The USFWS Wetland Inventory (WTI) identifies the fresh water pond as a Palustrine unconsolidated Bottom Permanently Flooded Excavated (PUBHx) wetland although the water level in the pond is variable depending on the yearly precipitation. The WTI did not identify the emergent wetland abutting the north side of the pond. The wetland is not listed as a state natural heritage wetland or a state wetland of high conservation value. The pond was nearly dry in 2007 when it was first delineate. The water level is very dependent on the amount of min fall from the small basin the wetland is in. For example in August 2007 the pond was nearly dry and at the end of 2014 the pond had little water in it and could have been dry until late October 2015 because of the drought. By the end of January 2016 the pond was nearly full. WETLAND Wetland Boundary Field review of the wetland on December 31, 2015 indicated that there Delineations: was no noticeable change in size or configuration of the wetland since 2008 but them has been a change in vegetation. Wetland In 207 the emergent wetland abutting the north side of the pond was Criteria: vegetation consisting mainly of introduced and native herbaceous plants. The emergent portion of the wetland abutting the north side of the pond is being invaded by Rosa nutkana. Rosa nutkana has nearly completely invaded the west arm of the emergent portion of the wetland and slightly narrowed the east am and the larger area of the emergent area. Also, the bank of the pond now supports a cover dominantly of Rosa makana rather than herbaceous. The area of emergent wetland area on the southwest end of the pond still has it dominant herbaceous plant cover. The areas being invaded by Rosa makana are identified in the original delineation drawing in Appendix 1. The soils for the wetland ranges from very dark gray sandy loam to gray fine sandy loam in the upper 16 inches to brownish gray to dark brown fine sands from 16 inches to at least 37 inches. Common prominent mottles are in the soils starting at 7 inches to a depth of 29 inches. The Reeter 999008303 LSWC Page 4 Page 15 soils below 16 inches are depleted. The soils best meets the hydric soil field indicator Al 1 (Depleted Below Dark Surface)? The wetland is a depressions] wetland as defined by the HGM classification of the Western Washington Rating System. Water in the wetland comes from precipitation as well surface and subsurface flow from a small drainage basin (Figure 3 in the rating system, Appendix 11). The wedand has no defined stream outlet and is considered to be within an enclosed basin. Wetland Rating_ The wetland was re -rand using the updated 2014 Washington Wetland Rating System'. The classification rating sheets and accompanying figures can be reviewed in Appendix 11. Table 1 below provides compiled summary of wetland rating data.

Reeler 999008303 LSWC Page 5 �6 Buffers The wetland requires a 110 feet wide buffer based Jefferson County Code JCC Table 18.22.330 (2). The buffer width of 110 feet is shown in the original wetland delineation drawing in Appendix A. Only those wetland stations required to establish the new buffer boundary width were established on the east end of the pond. The east end of the pond was used since it is the closest area of the wetland to the new proposed primary and reserved septic fields for the proposed meadery production bam. There was no need to establish the wetland boundary stations on the west side as all the new buffer width extends onto other private property. Besides stations on the east end of the pond wetland boundary stations were established on the southwest end of the wetland to help project the new buffer onto aerial photos were dense stands of Rosa nutkana prevented establishment on the ground. The marked on ground buffer boundaries and the projected boundaries are shown in Exhibit 11 on Page 7. The entire new proposed cottage industry site is well beyond the 110 foot Category III Wetland buffer CONCLUSIONS The re-classification of the wetland under the wetland rating system resulted in the wetland still being a Category IR Wetland. The habitat in the rating system rated moderate impact land use requiring a 110 foot buffer as prescribed in JCC Table 18.22.330(2). The primary 110 foot buffer was established on site to meet requirements under JCC 18.22.330 (3) (c) (ii) and (iii) and (6) (i) and (ii).

HGM Classification of Wetlands in Western Washington For questions 1-7, the criteria described must apply to the entire unit being rated. If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question E. 1. Are the water levels in the entire unit usually controlled by tides except during Floods? / NO - go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low Flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use Che forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is Oat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. ANO - go to 3 YES - The wetland class is Flats Ifyour wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire Wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac [8 ha) in size; _At least 30% of the open water area is deeper than 6.6 it [2 m). ;'NO - go to 4 YES -The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire Wetland unit meet all of the following criteria? The wetland is on a slope (slope can be verygroduol), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, =The water leaves the wetland without being impounded. AND - go to 5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually e3 it diameter and less than 1 it deep). S. Does the entire Wetland unit meet all of the following criteria? _The unit is in a valley, or stream channel, where it gets inundated by overbank Flooding from that stream or river, _The overbank flooding occurs at least once every 2 years.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, ifpresent, is higher than the interior of the wetland. NO -go to 7 ./YES -The wetland class is Depressional Is the entire wetland unit located in a very Flat area with no obvious depression and no riverbank Flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine Floodplain, or a small stream within a Depressional wetland has a zone of Flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use thistableonly if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.
