The RVCA and our member municipalities encourage pre-consultation in advance of submitting a formal Planning Act application. At a pre-consultation meeting, the applicant, the approval authority and the review agencies will discuss the proposal and the reports that may be necessary to support the application. The pre-consultation process assists the applicant in preparing a proposal that will meet the policies and submission requirements of the municipality, the RVCA and other agencies, potentially saving time and money.
The applications reviewed by the RVCA include:
- plans of subdivision and condominium
- severances
- minor variances
- comprehensive zoning by-laws and zoning by-law amendments
- official plans and official plan amendments
- site plans
- lifting of reserves
The RVCA also participates on technical advisory committees that oversee the preparation of broader planning studies such as community design plans, master servicing studies, environmental management plans and environmental assessments. We also review applications and provide advice on applications that are submitted under the Aggregate Resources Act.

Stillwater Creek Slope Stabilization Project
RVCA was contracted by the City of Ottawa to design and implement remediation of an eroded bank of Stillwater Creek adjacent to Nautica Private and Carling Avenue and into the Ottawa River. Erosion of the slope is being caused by fluctuating flow and velocity in the creek and this project will help prevent potential slope failure.

| East Bank Erosion | East Bank Erosion |
The headwaters of Stillwater Creek begin in the National Capital Commission’s Stoney Swamp. Stoney Swamp is almost 2000 hectares in size, and is a mix of woodland, wetland and regenerating fields. From Stoney Swamp, Stillwater Creek runs through a heavily channelized and impacted area adjacent to Robertson Road. The creek turns into its natural morphology downstream of Robertson Road until the Highway 417 crossing. It then becomes channelized again, as it runs through Wesley Clover Park on Corkstown Road. The creek flows through another large wetland before Moodie Drive crossing, and from there runs parallel between Highway 417 and Corkstown Road until it turns north flowing through residential neighborhoods before emptying into the Ottawa River between the Nepean Sailing Club and Andrew Haydon Park.
The first phase to be completed is on the west bank of the creek in the treed area. The highlighted blue area is the East bank portion of the work to be completed as the second phase.

Further erosion of the bank of Stillwater Creek at Nautica Private could be detrimental to the properties on Nautica Private and to the safety of the residents.
Rock Toe Berm Construction
RVCA looked into multiple alternatives for the slope stabilization of the banks of Stillwater Creek. RVCA decided on the construction of a rock toe berm to stabilize the east bank of the creek. Once the design was complete, RVCA had it checked by a third-party local geotechnical engineering firm.
The rock toe berm has been designed to make a “key” at the base of the slope to be filled with large “rock protection” sized stones. The slope will then be backfilled at a 1.5:1 (h:v) slope and the large stones will extend above the creeks assumed 100-year flood elevation. The work is expected to protect the properties on Nautica Private from further property damage due to erosion.
Timing
The project took place from approximately December 2, 2019 – February 28, 2020.

Watershed Conditions Statement: Forecasted Precipitation to Increase Water Levels Across Rideau Valley Watershed
(WCS – R08/2024)
August 08, 2024 – The Rideau Valley Conservation Authority is issuing a WATER SAFETY message for the entire Rideau Valley Watershed.A low-pressure system associated with remnants of Tropical Storm Debby is expected to produce heavy rainfall throughout the region. Local estimates of 50 to 100 mm of rainfall are possible beginning Thursday evening and continuing into Friday. Despite above normal precipitation over the last month, stream flows have generally stabilized at normal seasonal levels.
Although riverine flooding is not anticipated at this time, all water levels and flows across the Rideau Valley Watershed are expected to increase. Depending on the location and rainfall intensity, localized flooding in low-lying areas, including ditches and stormwater features, may be possible. Flows on the Rideau River are not expected to increase significantly.
It is advised that residents adjacent to smaller tributaries and streams take precautionary measures to protect their property, including:
- Ensuring sump pumps are clear, in good working condition and have a backwater valve
- Ensuring easy access to a portable backup generator and pump
- Ensuring downspouts are clear and the outlet is at least 3 metres from the dwelling
- Securing items that might float away as flows increase
Until the water levels and flows recede, the RVCA advises the public to exercise extreme caution around ALL WATERBODIES and remind children about the dangers of playing near open water.
This watershed conditions statement is in effect until Friday, August 16, 2024 at 5 PM or until an update has been issued.

RVCA Watershed Conditions Statements:
- Water Safety – High flows, unstable banks, melting ice or other factors that could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc. Flooding is not expected.
- Flood Outlook – Early notice of the potential for flooding based on weather forecasts, calling for heavy rain, snow melt, high winds or other conditions that could lead to high runoff, cause ice jams and/or lakeshore flooding or erosion.
- Flood Watch – Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individuals in flood prone areas should prepare.
- Flood Warning – Flooding is imminent or already occurring in specific watercourses or municipalities.
Our low water index has four stages:The RVCA issues water conditions statements to inform residents, municipalities and other stakeholders of changing water levels across the watershed.
A green gauge means conditions are normal. No low flow or drought conditions exist.
This category reflects concern.
80% to 60% of long-term average precipitation for 540 day and/or 90 day precipitation totals and/or 7-day average streamflows less than the 5 year return period low flow.
This category suggests a potentially serious problem is pending.
60% to 40% of long-term average precipitation for 540, 90 and/or 30 day precipitation totals and/or 7-day average streamflows less than the 10 year return period low flow.
This category indicates a failure of the water supply to meet demand.
Less than 40% of long-term average precipitation for 540, 90 and/or 30 day precipitation totals and/or 7-day average streamflows less than the 10 year return period low flow.
