Plant Material 1. All plant material must be in accordance with BCNLA/BCSLA Standards. 2. The contractor shall report any discrepancies regarding the use or availability of specified species to the Landscape Architect prior to purchase and installation. 3. Ensure good soil to root contact. 4. Stock planted during the fall (Sept – Oct) and spring (Mar – April) has the best chance of surviving. Should planting occur in the spring, maintain a snow or silt fence between the plants and the water until high water has come and receded (usually June), by at least 12” in depth. 5. Protect all planted vegetation from animal browse (i.e. beavers, voles) and other damage with appropriate wire fencing and / or mouse guards while becoming established. Any material damaged or destroyed by animals is the responsibility of the Contractor and must be replanted. 6. The site must be kept free of noxious weeds in accordance with the BC Weed Control Act (RSBC, 1996). 7. Replacement Trees - It is the responsibility of the owner to irrigate and maintain the replacement trees such that an 90% success rate is achieved for three years, for a minimum of 3 full growing seasons following installation, where a growing season is considered no later than July 1st and ends no earlier than October 15th in accordance with the Tree and Shrub Replacement Criteria for Fisheries and Oceans Canada (Salmon Arm Sub-district, 1996). 8. Enhancement Plant Material - It is the responsibility of the owner to irrigate and maintain enhancement plant material such that an 90% success rate is achieved for one year, for a minimum of 1 full growing season following installation, where a growing season is considered no later than July 1st and ends no earlier than October 15th in accordance with the Planting Criteria and Recommended Native Tree and Shrub Species for Restoration and Enhancement of Fish and Wildlife Habitat (MELP, 1998). 9. Local plant sources are preferred, to ensure the plant stock is acclimated to the area. 10. Water plants by hand or with a temporary watering system that achieves full RMA coverage as required in order to achieve successful plant establishment. 11. Within 30 m of the pond, only organic landscaping treatments are permitted. Synthetic pesticides, herbicides and fertilizers are not permitted.

Earthworks, Fine Grading and Topsoil Placement 1. Establish a wide swale, as shown on drawings, to allow percolation of overland water flow to ground. 2. Ensure that material such as rock, riprap, or other materials placed on the banks or within the active channel or floodplain of the watercourse is inert and free of silt, overburden, debris, or other substances deleterious to aquatic life. 3. Ensure planting areas have weed-free topsoil from a source approved by the Landscape Architect. Shrub beds should have a minimum of 400 mm of topsoil, and trees should have a minimum of 400 mm around the root ball. Meadow areas should have a minimum of 150 mm of topsoil to encourage deep roots and facilitate drought resistance, and assist in rainwater retention on the property. Roll topsoil gently prior to seeding. 4. Do not place bark mulch or equivalent within 15 metres of the High Water Mark. However, woody material from the site can be chipped and enhance the soil within the RMA. 5. Protect soils for 1.8 m upslope of high water mark with geotextile, secured with rocks and stakes, to ensure that soils do not erode while plants become established. This type of erosion protection should occur on slopes steeper than 2.5H:1V.

Environmental Monitoring 1. All work within the Streamside Protection and Enhancement Area (SPEA) shall be monitored by a Qualified Environmental Professional (QEP), as defined by Riparian Areas Regulation (2004). The environmental monitor (EM) should have written authority to halt works until such problems are rectified. 2. Restoration activities in the dry should be monitored at minimum, weekly by the EM. In-stream works require daily monitoring, at a minimum. More or less intensive monitoring visits will be decided by the EM. The environmental monitor must be an appropriately qualified environmental professional (QEP) and should be provided with authority to modify or halt any construction activity if it is deemed necessary to do so for the protection of the environment. A sign listing the monitor’s company name and phone number should be posted at the job site. 3. A copy of the section of this document listing mitigation measures and all appropriate plans, drawings, and documents should be forwarded to the contractor or crew supervisor, and this information will be readily available at the site while during these works. 4. A pre-construction meeting should be held between the environmental monitor and the contractor undertaking the work on the site to ensure a common understanding of the best management practices for this project. 5. Monitoring reports should be issued after each site visit, as well as annual monitoring reports, and a Substantial Completion report issued at the end of the installation of plants and an appropriate watering system. 6. The Total Performance report should be issued at the end of the project only when the QEP determines that an 90% survival of the replacement trees are successful after three years. The remainder of the plan material must have a survival rate of 80% over the first year following establishment, ending September 15th after at least one full growing season.

Sediment Control and Protection of Aquatic Habitat 1. All works should be completed in accordance with the Land Development Guidelines for the Protection of Aquatic Habitat (Chilibeck et al., 1993). This includes establishing and maintaining a properly installed silt fence, and using appropriate sediment control measures to avoid sediment migration into water. 2. Prevent the release of silt, sediment, sediment-laden water, raw concrete, concrete leachate, hydrocarbons, or any other deleterious substances into any ditch, watercourse, ravine, or storm sewer system. 3. Construction areas should be visibly delineated with flagging to exclude equipment from the RMA on Wilson Creek. Fences may be necessary to keep equipment well back of tree roots and branches. 4. Any soil stockpiles should be located a minimum of 20 m from the HWM of Wilson Creek. Stockpiles should be stabilized with a temporary covering such as well-anchored plastic sheeting, with silt fencing installed around the base to reduce mobilization of sediment. 5. The work area should be isolated from Wilson Creek with silt fence and other sediment control measures as necessary to prevent the migration of sediment into the creek. 6. If soil is to be exposed for long periods of time, it should be stabilized with measures such as reseeding, mulch or erosion control mats. 7. Ensure machinery is operated from the bank of the stream and not in the stream channel to minimize impacts. 8. Put sediment control measures into place before starting any works that may result in sediment mobilization. 9. Construct any ditches, water bars, or water diversions within the work area so they do not directly discharge sediment-laden surface flows into the stream. Divert such flows to a vegetated area or constructed detention pond where flows can slowly infiltrate. 10. Remove excavated material and debris from the site or place it in a stable area at least 20 m above the high-water mark or active floodplain of the stream, as far as possible from the channel. 11. Use mitigating measures to protect excavated material from being eroded and reintroduced into the watercourse. Such measures include, but are not limited to, covering the material with erosion blankets or seeding and planting it with native vegetation. 12. When material is moved offsite, dispose of it in a manner that prevents its entry into any watercourse, floodplain, ravine, or storm sewer system. 13. If off-site fill is brought to the subject property for levelling or construction purposes, it should be of sufficient quality to meet applicable guidelines for Commercial Land Use outlined in the BC Contaminated Sites Regulation of the Environmental Management Act. 14. Ensure equipment and machinery are in good operating condition (power washed), free of leaks, excess oil, and grease. No equipment refuelling or servicing should be undertaken within 30m of any watercourse or surface water drainage. 15. Refuelling and maintenance should occur in one area that is located away (ideally the northeast corner of the subject property) from Wilson Creek. EBA recommends that a spill management plan be developed by the selected contractor prior to starting construction. Keep a spill containment kit readily accessible onsite in the event of a release of a deleterious substance to the environment. Train onsite staff in its use. Immediately report any spill of a substance that is toxic, polluting, or deleterious to aquatic life of reportable quantities to the Provincial Emergency Program 24-hour phone line at 1-800-663-3456 (i.e. greater than 100L of gasoline). 16. Do not use treated wood products in any construction below the high-water mark of the stream channel, to prevent the release of preservatives that are toxic to fish.

PLANTING NOTES General 1. These drawings should be read and interpreted with all drawing sheets and with the report: Environmental Assessment, Hiawatha Properties, Lakeshore Road, Kelowna British Columbia (Issued for Use). 2. The Environmental Monitor should flag out No-Disturb areas prior to construction. The extent of vegetation clearing within the RMA should be restricted to those areas required to construct the back channels only. 3. Prior to mobilization, the Qualified Environmental Professional (QEP) should assess the area for raptors nests (active or inactive) and active nests of all other birds, in order to avoid a contravention of Section 34 of the Wildlife Act. Should an active nest be present, this area should be protected from construction activities until the young have fledged. 4. If trees are suspected of being hazardous, then also have them assessed by a qualified Wildlife Danger Tree Assessor, to determine the presence and nature of the hazard. 5. In-stream work should only occur within the suggested Fisheries Work Window (August 15 to March 1). 6. Fish and wildlife salvage permits must be obtained for salvage where work must occur in isolated areas within the stream prior to work. Only qualified persons may conduct the fish and wildlife salvage.
