COMMENTS FROM THE PUBLIC AND AGENCIES: The Community Development Department received comments from the following parties prior to the hearing: Sydney Hanson, Transportation Archaeologist, Washington Department of Archaeology and Historic Preservation – October 27, 2020 Ms. Hanson revised an earlier recommendation from the Washington Department of Archaeology and Historic Preservation (DAHP) submitted during the County’s SEPA review. DAHP now recommends an inadvertent discovery plan. DAHP recommends that the inadvertent discover plan is kept onsite throughout construction, and that construction crews are prepared for the possibility of encountering archaeological resources during construction. DAHP also recommends continued consultation with the concerned Tribes' cultural committees and staff regarding cultural resource issues. Staff recommends that DAHP’s recommendation be included as a condition of approval. STAFF ANALYSIS: COMPREHENSIVE PLAN - The subject property is located within the Swift Subarea and designation Mountain Recreational. The purpose of this land use designation is to provide areas of recreational uses at very low density to preserve the primitive recreational character of the area. Mountain Recreational areas accommodate demands for very low-density recreational cabins in a remote recreational area. The proposal is for a five-lot residential subdivision using density transfer. Single-family dwellings are allowable in this designation. Policy LU.1.1 encourages clustering development to increase green space and habitat. Skamania County Community Development Department SUB-20-01 (Muddy River Subdivision) Staff Report Page 3 ZONING - CHAPTER 21.68.060 – MOUNTAIN RECREATIONAL 5 ZONE CLASSIFICATION (MR-5) B. Allowable uses. Single-family dwellings; . G. Minimum Development Standards. 1. Lot Size. The standard minimum lot size, dimensions, and proportions shall be as follows (unless the local health authority requires a greater lot size): a. Minimum lot size shall be five acres. Finding: The subject property is located within the Mountain Recreational (MR-5) zone which allows for single-family residential development and requires a minimum lot size of five acres. The applicant qualifies for smaller individual lot sizes under the density transfer for residential land divisions provisions in SCC 19.01.080(D)(7). Based on the overall parcel size of 26.66 acres, this subdivision qualifies for five lots. Four of the proposed lots are proposed to be 2-acres to 2.79 acres in size. The remaining parcel would 17.16 acres, which would include a conservation easement. CRITICAL AREAS - CHAPTER 19.01 – GENERAL CRITICAL AREA PROVISIONS 19.01.080 General critical area regulations. 7. Density Transfer for Residential Land Divisions. The county shall allow transfer of density for residential uses from lands containing critical areas, as defined by this title. In order to accommodate the density transfer, the county may allow reductions in setbacks and lot dimensions and sizes. a. The basis for the density transfer will be calculated for the entire property as if it did not have the critical area, subject to the provisions of the underlying zoning designation. Finding: The subject property includes several critical areas, including fish and wildlife habitat conservation areas, critical aquifer recharge areas, floodplains, and geologic hazard areas. In order to protect the most sensitive of these areas and allow for development on the remainder of the property, the applicant has proposed to use density transfer. The total parcel size is 26.66 acres, qualifying the subdivision for five lots under the conventional minimum lot size of 5 acres in the Mountain Recreational 5 zone. The County will allow reduced lot sizes in order to accommodate the density transfer and protect critical areas. Four of the proposed lots are proposed to be 2-acres to 2.79 acres in size. The remaining parcel would 17.16 acres, which would include a conservation easement. b. Residential density may be transferred only from a critical area to an area on the same site that is not a critical area. Skamania County Community Development Department SUB-20-01 (Muddy River Subdivision) Staff Report Page 4 Finding: The property includes several critical areas, so it is not possible to restrict development on all sites that include critical areas. Instead, the density transfer will be based upon only those areas that are riparian habitat areas associated with the Lewis River and the Muddy River. A Critical Areas Report provided by the applicant establishes a 250 ft. buffer along the Lewis River and a 150 ft. buffer along the Muddy River. These buffers cover a significant portion of the southern portion of the subject property, including most of peninsula that is separated from the main portion of the property by the Muddy River. These riparian buffers are indicated by red shading in Figure 1 below. Figure 1. Riparian Areas. The applicant has proposed to establish an undeveloped conservation area lying east of the west ordinary high-water mark of the Muddy River. This proposal excludes the riparian buffers of the Muddy and Lewis Rivers which lie west of the ordinary high-water mark. Staff recommends that the conservation area be extended to include all riparian buffers and the small area on the peninsula that lies outside these buffers. This area consists of approximately 15.38 acres. Transferring the density from this area to those areas of the property outside riparian areas would allow for five lots to be developed on the remaining 11.28 acres. c. The critical area shall be permanently protected as undeveloped land by an easement or other similar restriction acceptable to the county. Finding: The applicant has proposed to establish an undeveloped conservation area lying east of the west ordinary high-water mark of the Muddy River. In order to comply with the density transfer provisions, staff recommends a condition of approval that the undevelopable conservation area be extended to include riparian areas located west of the west ordinary high-water mark of the Muddy River. This area shall be clearly Skamania County Community Development Department SUB-20-01 (Muddy River Subdivision) Staff Report Page 5 delineated on the plat map with the following note: This plat utilizes density transfer for residential land divisions under the Skamania County Critical Areas Ordinance. This area is permanently protected as undeveloped land and shall not be further divided.

  • Lewis River ~ Including Clear, Quartz, Siouxon, Pine, Rush, Smith Creeks & the Muddy River
    Photo by Susan Saul Wild and Scenic Rivers Support Local Communities The legendary volcanoes in southwestern Washington and the spectacular rivers that originate on their slopes are valuable to the health, economy, and cultural identity of local communities. Rivers like the Green, Cispus, and Lewis provide drinking water to thousands of local residents, world-class recreation, and a high quality of life for local residents. Designating the rivers and key tributaries in Volcano Country under the Wild and Scenic Rivers Act will increase long- term potential for recreation and tourism in the area, ensure cool clean water for fish and people, and protect these natural treasures for future generations. Just a few of the benefits of Wild and Scenic designation include: RECREATION, TOURISM, AND THE ECONOMY: According to the Outdoor Industry Association, outdoor recreation brings in more than $11.7 billion annually to our state, supports an estimated 115,000 jobs, and generates $650 million in annual sales tax revenue. Travel and tourism provide nearly 8000 jobs – or 14 percent of jobs across all economic sectors – in Lewis, Cowlitz, and Skamania counties. In addition to putting a river “on the map” for visitors and outdoor enthusiasts, a Wild and Scenic River designation can lead to access improvements and foster growth in river-based outdoor recreation and tourism. For example, a recent study of the Wild and Scenic section of the Rogue River found that commercial rafting, fishing, and other recreation contributed $30 million a year to the State of Oregon’s economy. The White Salmon and the Klickitat River are two positive examples of Wild and Scenic Rivers in Washington that benefit local recreation economies.

  • Forest Development Following Mudflow Deposition, Mount St. Helens, Washington
    437 Forest development following mudflow deposition, Mount St. Helens, Washington Marc H. Weber, Keith S. Hadley, Peter M. Frenzen, and Jerry F. Franklin Abstract: Volcanic mudflows are locally important disturbance agents in the Pacific Northwest rarely studied within the context of forest succession. We describe 18 years (1981–1999) of forest development on the Muddy River mud- flow deposit following the 1980 eruption of Mount St. Helens using permanent plot data collected along two transects traversing the Cedar Flats river terrace. We analyze changing forest structure over the study period and compare results with mudflow deposition using correlation and pairwise comparisons, as well as ordination (detrended correspondence analysis) and cluster analysis. Our results show a statistically significant relationship between mudflow deposition and forest change. Following mudflow deposition, the site consisted of patches of high tree mortality caused by deep mudflow deposits in abandoned river channels as well as patches of accelerated regeneration of surviving understory trees in areas of more shallow mudflow deposition and partial overstory mortality. Mudflow deposition at the site initiated multiple stages of stand development with (1) early-colonizing red alder (Alnus rubra Bong.) dominating deep deposition sites with fewer surviving trees, (2) gap recruitment and establishment by western hemlock (Tsuga heterophylla (Raf.) Sarg.) and Douglas- fir (Pseudotsuga menziesii (Mirb.) Franco) on intermediate to deep deposition sites with more postburial surviving trees, and (3) late-seral conditions and accelerated succession on shallow burial sites, where tree mortality was low. The initia- tion of differing succession trajectories, as well as variability in the extent and timing of tree mortality following mudflow deposition, demonstrates a dynamic response to disturbance in relation to small-scale gradients of mudflow deposition.

    1. Project Title Muddy River Tributary near Hoo Hoo Bridge 2. Project Manager Adam Haspiel Mt. St. Helens National Volcanic Monument 42218 NE Yale Bridge Road Amboy, WA 98604 360-449-7833 360-449-7801 (fax) [email protected] 3. Identification of problem or opportunity to be addressed Problem: The Muddy River and some tributaries were highly impacted by the volcanic eruption and subsequent lahar events of the 1980 eruption of Mt. St. Helens. Impacts include loss of mature riparian vegetation, high mobile sediment loads, loss of functional large woody material, channel instability, and increased summer water temperatures. Restoring or enhancing side channels and tributaries is critical to ensure success of reintroduced salmon and steelhead in the Muddy River Watershed. This habitat is essential for species listed under the Endangered Species Act (ESA) that use this watershed within the Lewis River Basin, including Lower Columbia River coho and Chinook salmon, steelhead trout, and bull trout. These species have endured many effects that threaten their survival in the watershed. Effects in addition to the Mount St. Helens eruption and associated lahar event include sediment inputs, shade reduction, large wood removal and passage barriers from past land management activities such as logging, roads, and development of hydro- resources, which until recently has blocked all access into the upper watershed for anadromous species since the 1930’s. To ensure reintroduction efforts of salmon and steelhead into the upper basin are successful the Forest Service has worked with PacifiCorp on a variety of projects including acclimation ponds for juvenile spring Chinook salmon, road decommissioning, replacement of migration blocking culverts with bridges, and various streambank and instream fish habitat restoration projects.
