Document SP No D-002Date:April 14, 2015 provides an understanding of the elements guiding the implementation of the Restoration Plan, some specific examples follow:

1. Natural Environment Timing Windows

All timing windows identified by permits and approvals from DFO, MNR, MVC, MOE, Ottawa and others will be respected. Many of these have been issued with respect to fisheries, flora, fauna and water takings and will have to be considered by the contractor in establishing the timing and sequencing of their construction operations over the four year construction period. It will be the responsibility of the contractor to identify all necessary timing windows and develop a construction schedule that will accommodate them. Currently known windows reflect fisheries and endangered species breeding periods and locations and are provided in the agreements with MOE, DFO and MNR as identified in D-2015-01-12 Permits and Approvals. Theses windows include:

 No vegetative clearing during turtle nesting period (typically June)  Any instream work, diversions or any operation impacting any watercourse or its tributary receiving waters in any way shall be prohibited from March 15th to June 30th.  These timing constraints apply regardless of the timing of the Contract. (page 14)

2. Erosion and Sediment Controls – Excavation Exposure

As part of erosion control, a determination has been made as to the maximum amount of excavation that can be exposed at any given time, in any given location, based on soil types, silt fencing and application of Revised Universal Soil Loss Equation (RUSLE) methods (page 15)

3. ENVIRONMENTAL PROTECTION – AQUATIC AND TERRESTRIAL - HABITAT AND SPECIES (pages 26-28) SP No D-002Date:April 14, 2015

4. GENERAL GRADING AND EARTHWORKS

All cutting and filling shall be performed in such a manner to avoid flooding or ponding of water on the site or any adjacent properties. At no time during the contract, should the volume of fill exceed the volume of cut. Surface drainage shall be provided during all stages of the work and fill materials placed as soon as possible to prevent ponding in sub-excavated areas. (page 30) SP No D-002Date:April 14, 2015

5. Environmental protection

Minimum 30 minute environmental awareness training for all personnel on site  Regular site meetings (weekly) with site personnel as a reminder of seasonal environmental concerns  Daily work area monitoring for turtles; monthly reporting  Provide Erosion and Sediment Control (ESC) Plan to MOE  Daily logbook of ESC activities  Daily surface water TSS monitoring for each active area  Monitoring reports (weekly, monthly, annual) as required by the permits/approvals provide to Contract Administrator for confirmation and submission to appropriate agencies  When necessary, obtain fish salvage/stranding (capture and release) permits, for dewatering and diversion activities  All fisheries and turtle related activities to be undertaken by qualified personnel  Follow agency prescribed protocols for all natural environment monitoring and works  No vegetative clearing during turtle nesting period (typically June)  Any instream work, diversions or any operation impacting any watercourse or its tributary receiving waters in any way shall be prohibited from March 15th to June 30th. These timing constraints apply regardless of the timing of the Contract. (page 33 SP No D-002Date:April 14, 2015

Why it is important to monitor the Carp River Restoration Project

Does it accomplish the restoration goals to:

• improve sediment transport in the channel,

• minimize erosion,

• allow for efficient flow conveyance and a natural flow regime, and

• enhance aquatic and terrestrial habitats? (WEPP Aquatic Habitat Restoration Monitoring Report – 2011 page 1)

Does it meet the conditions laid out by MOE and which is perhaps more clearly formated on the City's website?

Does it comply with the Provincial Policy Statement?

Does it comply with the KWOG 2010 Implementation Plan, Kanata West Development Area report page 25

Who's doing the post-restoration monitoring?

Wetlands are an important component of a healthy functional ecosystem and provide a variety of ecological services that benefit humans. These include:

• Improvement of water quality

• Reduction of flood damage

• Reduction of erosion

• Groundwater recharge and discharge

• Provision of habitat for fish and wildlife

• Recreation and tourism (e.g. fishing, hunting, nature enjoyment etc.)

• Sustainable wetland products (e.g. wild rice, cranberries, baitfish etc.)

• Retention of carbon to help slow the release of greenhouse gases

The Carp River Restoration Project, the City's most extensive and expensive wetland rehabilitation endeavour ever undertaken, was necessiated by the negative impact on the wetland from land development in the area. Over the past 14 years plans have been developed to improve the wetland by::

• reducing sediment transport in the river's main channel,

• minimizing erosion,

• allowing for efficient flow conveyance and a natural flow regime,

• enhancing aquatic and terrestrial habitats and

• facilitating recreational enjoyment.

Spring of 2016 will mark the first evidence of the plan's implementation and the community's interest in helping to monitor the outcomes.

The Kanata West wetland is a riparian zone linking the terrestrial areas of mainly developed land with the aquatic zone of the river. . Restoring the diversity and complexity of the riparian zone with its many ecosystem services and wildlife functions will be a challenge that will take years to determine success.

Riparian zones are connectors between aquatic and terrestrial ecosystems that contribute resources such as woody structures, nutrients and shade. One of the challenges in creating a quality river habitat in the Kanata West floodplain will be countering the many negative influences of the impervious land cover in the surrounding high density residential and commercial areas.. Measuring the water quality and fish communities will be an important source of information when assessing the effectiveness of the rehabilitatiion.

Ground cover

Suitable ground cover should provide erosion control, stormwater infiltration, provide carbon sequestration, support habitat diversity and grow in a variety of soil sun and shade and varities.

Wetland sedges are the dominant ground cover planted in the outer fringes of the riparian zone. Sedges are regarded as an appropriate plant for stabilizing the large amount of new fill brought into the wetland.

The wind-pollinated flowers of sedges are not attractive to insect pollinators. Sedges are host plants of the larvae of various butterflies, skippers, and moths. Grasshooppers, leafhoppers, aphids and various other bugs feed on sedges as well. Among vertebrate animals, the seeds of sedges are a significant source of food for various upland gamebirds, waterfowl, and granivorous songbirds (see Bird Table).

The seed mix has the potential for an aesthetically attractive and faunial

wetlands are able to assimilate some nutrients and toxic chemicals through plant uptake and the interaction of flowing water with microbial communities active in the wetland soils. These tiny organisms are able to transform and break down nutrients and some toxic chemicals.

wet ponds

• Wet meadows location map

• Type of seeds

• Specification of site preparation, materials required, method of application, and maintenance for naturalized seeding within the limits of the site. Seeding of the site is divided into 5 main classifications based on the characteristics, and functionality including:

  • Riparian;

  • Floodplain;

  • Wetland Meadow – Fringe;

  • Wetland Meadow – Transition; and,

  • Wetland Meadow – Core.

    • First Year - Observation of the growth of desired species and weed competition is essential to making maintenance decisions. When the undesirable vegetation reaches 200-300cm (80-120”) tall, mow to no less than 100cm (40”), with a mower or weed eater, to prevent weeds from going to seed. Most native plants will grow a deeper root system than top in the first year, and mowing 100cm (40”) high will not hurt them, this allows sunlight to reach desired species. DO NOT MOW WITH A LAWN MOWER Mowing too closely encourages weedy species. Second Year Mow once, close to the ground, in early spring. This allows the soil to warm more quickly and young native plants to emerge. CRRP tender specs 06 Who - Contract Administrator page 17
