Area B includes species found in the vicinity of the Site. Area C is to be replanted with a grass seed mixture following construction. WW1562-EastQuilceneHMP.Tab3/081618/mas 30 Planting Area C will be a 12 foot area around the house addition, wherever construction disturbance has occurred. This area will include planting of grasses, with limited shrubs and groundcover to avoid erosion in the construction area while still providing a use area around the home. Success of the Planting Plan depends on choosing species that are suitable to the on -Site soil conditions, but that are hardy and capable of handling nutrient poor soils, shading and some salt spray. The native vegetation selected for this Mitigation and Habitat Management Plan were chosen for these reasons. Soils on the Site are mostly sandy gravelly loams which are well drained. Normal rainfall will quickly drain through these soils. Plants may require additional watering during the first year in order to meet performance criteria. A simple drip irrigation system would be the most effective method of accomplishing this. The species, size and number of plants that will be used to revegetate these areas is shown in Table 3. Plants will be placed in a semi -random fashion within the areas indicated in Figure 6. Small trees will be placed on eight -foot centers (shore pine and oceanspray) and shrubs will be planted on six-foot centers or less. Staggering of plants, rather than planting in straight rows, will create a more natural appearing configuration. Plants may be clustered by species in order to promote natural reseeding. Plants installed in the fall usually out -perform those installed in the late winter or spring. Planting projects scheduled for early October to mid-December are generally the most successful. The earlier plants go into the ground in the fall, the more time they have to recover from transplant shock, adapt to the site, and expand their roots systems before the growing season. They will require less water and grow more vigorously than if they are planted in the spring. To increase the potential for the planted species to survive, four inches of mulch should be placed around the installed plants with the mulch two inches away from the stem of the plants. WW1 562-EastQuilcene. RPT/081618/mas 31 6.0 CONCLUSIONS AND RECOMMENDATIONS 6.1 CONCLUSIONS The Property presently has an existing home, garage and existing shed/outbuildings, all within the 150 foot buffer zone. The landowner intends to add on to the existing residence with an 1,150 or 1,170 square foot addition as approved by Jefferson County located on the southeast corner of the building. The addition will be no closer to the OHWM than the home to the south of the Property. The new addition will be placed roughly 60 feet from the OWHM. Measures outlined in this Report will be enacted to mitigate construction on the Site and incrementally improve habitat and vegetation in the nearshore area. Erosion control measures will include a silt fence and other standard measures and will be used during construction to minimize sheet and rill erosion. A Planting Plan (Chapter 5.0) (See Figure 6 and Table 3) will be implemented to provide additional vegetation adjacent to the shoreline, and in the construction zone of the house. Also, any invasive, non-native plants which are present should be removed from the buffer zone. This Report and associated Habitat Management Plan meets the intent of RCW36.70A.480 ensuring "No Net Loss of Shoreline Ecological Function" due to the Mitigation proposed, and applicable Jefferson County Codes. It is also intended to comply with requirements of the Federal Emergency Management Agency (FEMA) for requirements on floodplains and the Biological Opinion of the National Marine Fisheries Service (NMFS). 6.2 RECOMMENDATIONS This Report constitutes a Mitigation and Habitat Management Plan. A Planting Plan has been included in this Report and we recommend that it be implemented on the Site upon approval by the County. Benefits deriving from this Plan will only take place if it is implemented by the Property owners and enforced by the County. The silt fence should be emplaced at the western, southern and northern borders of the home addition prior to construction and should be_left in place throughout construction. Additional erosion controE m- ateri-a Is should be kept on Site to address any erosion observed during construction. The Planting Plan outlined in this Report should be implemented. The Plan should be monitored according to the instructions outlined in this report and the Contingency Plan implemented in the event that plant survival in the revegetated areas fails below 90 percent. WIN1562-EastQuiicene. RPT/0$161$/mas 32 Property owners should refrain from the use of pesticides or additional nutrients on the Site and should introduce no contaminants within 100 feet of the OHWM. While these measures will provide mitigation for additional construction and use of the Site, the shoreline and marine critical areas may experience some continued cumulative impacts as a result of the narrow size of the buffers and limited filtering capacity of the soils in this area.
