The report's content follows the six directives outlined in Jefferson County Code 18.22.520 Periodic Monitoring. "Critical area stewardship plans (CASPs) shall be monitored and reports submitted as prescribed by the approving authorities' implementation program. Monitoring reports shall be submitted to the department of community development, and shall include the following:" 18.22.520 (1) Identification of the goals, objectives and performance standards of the CASP including the specific performance standards adopted pursuant to JCC 18.22.465; CASP Goals: The goals of this management proposal are: 1. Mitigation of the immediate impacts of erosion during the construction process through the use of erosion control technologies and construction fencing. 2. Mitigation of potential impacts on native vegetation. This will include the removal of any invasive plants and replanting with native plants to compensate for plants removed during the project and to enhance the existing wetland buffer zone. 3. Because of the incursion of the new home and septic system into the buffer, the property owners should refrain from using pesticides or plant nutrients in the buffer replanting area or within 110 feet of the wetlands on the property. Buffer areas serve a variety of functions. They are important in that they reduce the adverse impacts of adjacent land uses by stabilizing soil and preventing erosion; filter suspended solids, nutrients, and toxic substances; and moderate impacts of stormwater runoff. Mitigating adverse impacts and enhancing buffers involves action both during and after the construction process. Actions during the process can involve the use of erosion control technologies while enhancement after the construction process is best accomplished by planting native vegetation. Narrowing the size of the buffers of both wetlands will limit their capacity to filter nutrients and pollutants from the water. By improving the native vegetation in the buffer, this capacity may be incrementally enhanced. 1 As a transition zone between aquatic and wetland habitats, buffers also provide important habitat for both animal species. Buffers provide habitat for small mammals as well as many bird species. The also provide habitat for many insect species. Revegetation of the septic system site and the planting areas within the buffer (see Figure 10) will enhance habitat in an areas adjacent to the wetlands. 3.4.2 Objectives The goals of this plan will be met through the implementation of the following objectives. These objectives are intended to achieve the goals of impact mitigation and the overall enhancement of the buffer area. 3.4.4.1 Performance Standards Table 3 lists the performance standards to be used in assessing the success of the overall Management Plan. Three indicators and related attributes will be used for determining the success of the planting plan in and outside the buffer zone: • The percent cover of invasive plants removed from the three planting zones • The percent cover of the combined total of native plants remaining and re-planted in the planting zones • The observation of erosion or sediment movement in the buffer zone Specific target quantities/statuses of percent cover ("action" in JCC 18.22.465) will be used to determine when the contingency plan should be implemented. A target quantity of five percent cover or less is set for invasive plants. If invasive plant growth reaches ten percent, the Contingency Plan is to be triggered. For newly planted native plants, a target goal of at least 90 percent total area cover is targeted. In the first year following planting, ground cover of less than 90 percent will trigger the contingency plan. In the second year and subsequent years ground cover of less than 85 percent will trigger the Contingency Plan. The action levels for both invasive and native plants will be attained by the first summer following the termination of the proposed project. In addition to plant cover levels, the presence of visible rill or sheet erosion will be a third indicator. A target of zero observed erosion in the buffer zone will be sought, and any visible erosion which cannot be mitigated immediately will trigger the contingency plan. This action level will be attained during the construction process through on-Site mitigation measures and maintained following construction through the planting plan. 18.22.520 (2) A qualitative comparison of the critical area functions and values present at the time of annual monitoring with conditions existing during creation of the CASP and conditions observed during previous annual reports; A "qualitative" examination of the planting areas reveals the following. The planting plan specified nine planting areas. Planting areas C, D & E to the east of the driveway/house and F, G, H, J, A & B to the west. 2 Area A & B Planting areas A & B continue to show good survival. The original plan called for the planting of just over 100 species in these areas. The PNW natives including Oregon Grape, Ferns and others continue to grow. We continue to battle invasive species in this area - primarily Horsetail & Vine Blackberry. I may be the only person around weed whacking a forest. Area C& D Planting areas C & D were re-planted in 2023. It was being overrun with invasive species. We kept several of the Red Elderberry trees that did well. The area was scraped by a front-end loader and a thick layer of mulch was installed on the bank to prevent any erosions, which had not been a problem. Subsequently the area was re-planted with primarily PNW native plants as outlined in the plant list on page 6. These plants are doing well. Area J In 2023 we added a layer of mulch around Planting area J to improve its aesthetics and to help suppress invasive horsetail. The native plants are doing well in this area as it gets a good amount of sun. We also overplanted ferns in this area and combined with the ferns that re- grew following constructions, area J is doing well and has a high survival rate. Area F, G & H Areas F G & H have been a challenge as the amount of sunlight has encouraged the growth of Horsetail and Vine Blackberry. Again, we continue to weed whack this area to try our best to limit the growth of these plants. While weed whacking I know I have whacked more than a few plants we want to keep. I have tried to mark when possible as I know they are still alive. Area E Given the two sizeable Cedar trees in area Ethe smaller plants have struggled to do well here. There are several of the Elderberry's that have survived and the ferns are doing well. (3) A discussion of real-time observation describing compliance with the performance standards described in JCC 18.22.465; Performance Standards (from CASP). Table 3 lists the performance standards to be used in assessing the success of the overall Management Plan. Three indicators and related attributes will be used for determining the success of the planting plan in and outside the buffer zone: • The percent cover of invasive plants removed from the three planting zones. 3 o There are a couple sections (primarily F, G & B) that the Horsetail has been a problem. There is absolutely no way to remove the Horsetail short of using DDT. We regularly control them by weed whacking back several times during the growing season. It is our desire to give the natives as much chance to survive and over time will shade out the Horsetail plants and they will stop expanding. • The percent cover of the combined total of native plants remaining and re-planted in the planting zones. o With the addition of plants to planting areas C & D as well as the addition of more ferns planted then called for, the percent of natives surviving is at or near the total number required in the CASP (264). • The observation of erosion or sediment movement in the buffer zone. o No erosion.

(4) When analysis of monitoring results describes a deficiency in meeting the CASP's goals, adaptive management shall be employed to rectify the deficiency; TBD (5) The landowner agrees to allow approved Jefferson County staff access to property for the purposes of monitoring; TBD Based on the county's performance standards, required qualitative review and noting that we in 2022 we planted more than the required number of plants, the areas appear to be within the range of the combined survival rate of 85% as called for in the performance standards for year three and beyond. 4 As part-time residents, watering all of the areas is a challenge. We attempted to keep the areas watered as best we can to protect our investment. The new area near the house and re-planted areas C & D have a timed watering system and watering is not an issue. Areas C & D, the only areas susceptible to erosion, we added a deep layer of mulch to not only help the plants survive and block out evasive plants, but also to control any possible erosion. There is a significant drainage system built into the bank that drains water to the rain garden on the west side of the property. The combination of the two has remediated any erosion. There are invasive species that have done well in areas with natural light. We try to mitigate, but it's a challenge. The horsetail is especially pesky and based on advice from several professionals it is impossible to eradicate without mature plants to block the sun. The best we can do is weed whack and give the natives the chance to block out the horsetail. Given that the only "predator" for the Horsetail is (according to our plant expert) the Brontosaurus, we will be battling this plant for several years. My guess it may never be 100% gone, but one can hope. Some of the plants first appeared on the property next door many years ago. Invasive plants also arrived via the soil we purchased and had delivered from Shold in 2022 to bolster and support the plants we planted in areas C, D & E. In addition to the total number of plants required by the CASP, the number actually planted was closer to 275-280 as we transplanted an additional 7-10 ferns from other parts of the property. If a site visit is required, please coordinate with the owners.

When we re-planted, we kept the Elderberry trees that were thriving and added an additional 31 plants, primarily PNW Natives. We did not re-plant the ferns as the landscape professional we hired said that at this time with the amount of sun creating such a 'hot' spot on the bank, ferns will not do well. We will add some back as the Elderberry trees create more shade, but for now we are holding off planting any ferns. The total for Areas C & D now stands at approximately 35 plants. The diversity of the plants does not fall in-line 100% with the CASP, but we feel it more than follows the spirit of the CASP and is far more interesting to the eye of the homeowner than what was originally envisioned. With the addition of the planting areas adjacent to C & D that are not part of the CASP, we have now planted 539 plants, with approximately 80% of that total being PNW native plants. 7 n-cs .tS A PUHltNG DCCt.:ftiCN1 Ol'itr m roe GY§l'li'tCP fl'I'!? a::n:c eva,; § ¥f'l!l0fP BY Pfl: HF.Al Ct OffARiW!'i! ----===--c'L..- ...... ;;;,...,.., t,: •~:ii.,.~•,:·"' .~~A•o. • (,It!.~~- ,t t ', •• ~ ·\ -- r-,-: ~ .. ~ ______ , ... -- ~ - __ J\ ·-:·- - -D ~=:) ·, \ , a; I "~ v· 0 - =.E~~ - '"'\: ~ --~ l >- .... ,A...._ ....
