1.0 INTRODUCTION Golder Associates Ltd. (Golder) was retained by Mr. John Vinje (the Proponent) to complete an Impact Assessment (IA) for the addition of pilings to anchor a private dock at a property on Marble Point. In addition, Golder was asked to submit a Land Tenure application and Water Act notification (BC FrontCounter), a Navigation Protection Act application (Transport Canada), and a development permit for upgraded docks (Columbia Shuswap Regional District) on behalf of the Proponent. The existing dock is not licensed and according to the Ministry of Forests, Lands and Natural Resource Operations (MFLNRO), letters are being sent out to property owners with unlicensed docks to get the docks licensed1. Improvements made to the dock will trigger a requirement for approval from the province for tenure. The size of the current dock and walkway is greater than 24 m2, so Specific Permission will need to be granted (MFLNRO 2011).

The site (Block B, District lot 6052, KDYD Plan 9TU1509) is located approximately 6.2 km southeast of the Cinnemousun Narrows, on the Salmon arm of Shuswap Lake (Figure 1). The north end of Marble Point is developed with residential properties, while the south end is a wilderness campground, one of 23 sites that make up the Shuswap Lake Marine Provincial Park. The lake forms part of the Shuswap Watershed, which connects to the Fraser River and ultimately to the Pacific Ocean through the Thompson River. A big return of sockeye salmon is expected in the fall of 2014, and biologists are predicting between 7.2 and 72 million salmon to return to the Fraser River watershed (CTV 2014). Given those numbers, salmon are likely to spawn in sub-par habitat this year.

The scope of this IA includes an inventory of the biophysical resources of the site and an assessment of the environmental effects of the existing docks and proposed changes to the docks on these resources. Additionally, a recommended dock layout and mitigation plan to reduce any adverse environmental effects has been prepared.

2.0 SITE ASSESSMENT Golder (Jason Marzinzik, B.Sc., R.P.Bio.) conducted a site reconnaissance on June 20th 2014 to document the existing environmental conditions of the site. A follow-up visit was conducted on July 3, 2014 by Darryl Arsenault, M.Sc., R.P.Bio.

The following is a description of the existing site characteristics.

Shoreline erosion is evident along the 17 m length of the property. In 2012, Golder recommended shielding the bank using riprap, coconut mat and shrub plantings. The shoreline does not appear to have eroded further to that time but still lacks shoreline vegetation and woody debris. Shoreline erosion protection measures and enhancement recommendations are not included in this report.

The rip rap that is currently present has a horizontal slope of 3.7 m and a vertical slope of 2 m, a slope ratio of approximately 2:1.

The substrate below the high water mark (HWM) is predominately angular cobble with a small amount of boulder and gravel, while the substrate above the HWM is predominately fines and gravel. The forest floor above the HWM is rich in loamy topsoil, which supports plants such as Douglas maple, Nootka rose, red-osier dogwood, water birch, paper birch, Sitka alder, western red cedar, and interior Douglas fir. The shoreline type, below the natural boundary, does not support foreshore2 vegetation due to the erosive wave action.

The existing dock system (photos 1 to 4) does not comply with Best Management Practices (BMP) (Columbia Shuswap Regional District 2012, Ministry of Agriculture 2013, Ministry of Environment 2006) because dock 2 is too wide and, given its size, is placed above water that is too shallow (Figure 2). In addition, the dock has a covered gazebo, a structure that does not meet BMPs (Ministry of Agriculture 2013). Dock component details and dimensions include a:

Cantilevered walkway made from aluminum with Thru Flow™ decking: 11 m long x 1 m wide;

Dock segment 1 made with steel pontoon floats and wood decking: 12.3 m long x 2.6 m wide; and,

Dock Segment 2 made with steel pontoon floats and wood decking: 8.6 m long x 8.65 m wide.

The existing cantilevered deck (photos 5 to 6) appears to have been built suspended over Crown land. Its dimensions and position are below.

The deck is made from aluminum with Thru Flow™ decking: 7.8 m long x 4.5 m wide; and,

The deck was 2.09 m from underside to water, 2.78 m from underside to substrate (water level was 348.41 m above sea level on June 20 20143). This means that the deck and cantilevered walkway were located at 350.5 m above sea level.

3.0 EFFECTS ASSESSMENT AND MITIGATION The docks appear to be anchored in position by concrete anchors and ropes and moved with corresponding water levels. They are close to shore and the nearshore end was grounded during each site visit. The grounding would tend to impact fish habitat by scouring the substrate and by shading potential periphyton4 production. The grounding may also alter longshore sediment transport and water flow along the shoreline. Boat activity close to shore can introduce pollutants from the motor and bilge water into shallow water where it is less likely to get diluted, and propellers can cause damage to the lakebed by churning up sediment in shallow water.

Several modifications need to be made to the existing docks to meet BC government standards, prior to adding pilings and anchoring in a more permanent position.

4 Periphyton is algae that grows in waterbodies on substrate such as rocks or logs.



The dock segments were placed in water that was <1.5 m deep at low water. Guidelines state that floating docks can only be anchored in water that is deeper than 1.5 m at all times (Ministry of Environment 2006). Small fry typically swim in shallow water along the shoreline, and the shade created by a wide dock has potential to attract predators and impact populations. In addition, boats that are moored in shallow water can cause damage to fish habitat due to propeller scour.

Both docks should be moved further from shore so that dock segment 1 (2.6 m wide) is floating at least 1.5 m deep, and dock segment 2 (8.65 m wide) is floating at least 6 m deep (Figure 3 and Appendix A, Sheet 03). Pilings can be placed to anchor the docks once they are at the appropriate depth. These changes would result in compliance with not only the private moorage standards but the commercial standards as well for the large dock segment. The cantilevered walkway (1m wide) should be extended appropriately and supported by piles at an elevation that keeps it above high water at all times (at least 350 m above sea level).

Dock segment 2 currently has a covered gazebo with a waterslide and solar panel on the roof of the gazebo. According to the Ministry of Agriculture (2013) and MFLNRO (2013a), docks are not supposed to support any structures). According to best management practices, the gazebo should be dismantled and removed; however, the structure would not be expected to have a negative effect on the environment if it is placed over deep water.

The cantilevered walkway meets the criteria for appropriate width at only 1 m wide. In addition, it is comprised of small gauge materials (aluminum frame) and the Thru Flow™ decking allows some light penetration. The walkway should be supported by small diameter piles and extended out and adding a ramp down to the relocated docks. The conceptual layout is provided on Figure 3 and the cross section is illustrated in Appendix A.

The impact of the cantilevered deck is likely minimal because the light-weight aluminum frame and Thru Flow decking allows light to go through to the foreshore and the shoreline beneath the deck is too high in elevation to be fish spawning habitat (i.e., substrate exposed to air during sockeye and lake trout spawning period). In addition, the erosional nature of the foreshore is such that vegetation does not grow below high water and any shading from the deck would not shade vegetation.

Moving the docks into deeper water, extending the walkway and supporting with pilings, and adding a ramp down to the floating docks is not expected to have negative effects on water quality or sedimentation (erosive shoreline area). Making the suggested improvements is expected to reduce the negative impacts of the existing structures. Public access will not change.

Golder recommends that the timing of pile placement should follow best management practices. As the shoreline segment has been rated as Low by the Foreshore Inventory Mapping and Aquatic Habitat Index, with no spawning potential for sockeye salmon or lake trout, there should be a work timing window from July 22 to April1.

REPORT - Columbia-Shuswap Regional District · The site (Block B, District lot 6052, KDYD Plan 9TU1509) is located approximately 6.2 km southeast of the Cinnemousun Narrows, on the
