Fences and interlock in Riverside South
Korvex builds fences, interlock, decks and backyards in Riverside South. The City’s design plan organizes the community around the Mosquito Creek valley, a set of stormwater ponds and a green corridor along the top of the river slope. Most lots are recent and graded to send runoff into that system, so a new fence, deck or patio has to keep the lot’s grading working.
Riverside South was mostly farmland until its first homes went up in 1996, and it is still building out between the Rideau River and Bowesville Road. About 19,800 people lived here in 2021, and O-Train Line 2 reached Limebank Road in January 2025.
What we plan around in Riverside South
The ground, the lots and the local rules
Each point links to the public source it was checked against. At the site visit we check how it applies to your lot.
- Recent lots and grading plans
Owners are expected to keep the grades set by the original grading plan, and swales and catch basins stay open. Newer homes are more likely to have that plan on record with the City.
What it changesdrainage & grading, interlock, backyard renovations
- Mosquito Creek valleylands
The creek valley is the centre of the community’s open space system. Yards next to it keep fill and runoff out of the valley slope.
What it changesretaining walls, drainage & grading
- Marine clay soils
The community plan calls for tree planting standards suited to marine clay soils. Clay under a new yard holds water, so base depth and compaction are planned for it.
What it changesinterlock, fences, decks, exterior waterproofing
- Rideau River slope
A green corridor follows the top of the Rideau River slope. Lots near it keep structures and grading changes back from the edge.
What it changesfences, retaining walls, backyard renovations
The first full backyard on a newer home
Fence, patio, deck and beds in one plan
Korvex Construction builds complete backyards for Riverside South homes: the fence, an interlock patio or a deck, low walls, garden beds and drainage, all fitted to the lot grading the house came with. The site visit and the estimate cost nothing, the written scope and price follow, and the way to start is a call, text or WhatsApp message to 613-880-7679.
Riverside South is still filling in, and its community association expects about 24,920 residents by 2034. Many yards here are first-owner yards: sod over the builder’s grade, a downspout or two, and a fence still to come. If you have the grading plan or any builder paperwork that mentions grading, bring it to the site visit, since the new work is set to those grades.
Some lots have a catch basin in the backyard. The City explains that it removes excess water for your lot and the lots that border it, and asks owners never to cover or block it, or pour anything into it, since it leads to a nearby waterway. A patio or deck is laid out so the grate stays open and reachable.
Building the yard in stages
The order that keeps finished work from being dug up
Some owners fence first, for children or a dog, and add the patio and deck later. That works when the full layout is drawn at the start, so each stage lands where the next one expects it. The order we follow:
- Demolition: builder’s leftovers, sod or old surfaces come out down to workable ground.
- Base and grading: the ground is shaped to fall away from the house, matching the grading plan.
- Drainage: French drains or clear-stone strips go in while the ground is open.
- Construction: fence, patio, walkway, steps, walls and deck on the prepared ground.
- Finishing: beds, borders, gravel and clean-up.
Honey Gables and the river side
Older lots and regulated land near the Rideau
Riverside South also takes in Honey Gables, three streets on the west side of River Road first built around 1950. Yards there are older than anything around them, with mature trees and earlier fences, sheds and patios to take out before new work.
Toward the Rideau River and along Mosquito Creek, the Rideau Valley Conservation Authority regulates flood plains, valley slopes and every watercourse in its watershed, whatever its upstream drainage area. Grading, fill and structures there can need its permit, and we check the regulated areas for your lot before planning the work.

We just moved into a new build. What do you need to plan the backyard?
The address, a few photos of the yard and any grading plan or builder paperwork you have. At the free site visit we check the grading, the downspouts and any catch basin, then the written scope and price follow. The fence, patio and deck are set to the grades the lot was built with.
There is a catch basin in our backyard. Can a patio go over it?
No. City of Ottawa guidance says a backyard catch basin must never be covered or blocked, since it drains your lot and the ones beside it. The patio is shaped around the grate and sloped toward it where the grading plan sends water that way.
Can the backyard be split into stages?
Often, yes. We plan the full layout first and do the grading and drainage early, so the fence, patio and deck go onto prepared ground in later stages and nothing finished has to be dug up again.
Do you work in Riverside South?
Yes. Korvex Construction builds fences, interlock, decks and backyards across Riverside South, on established streets and newer phases between the Rideau River and Bowesville Road. Most lots here follow a recent grading plan, and we set patio height and slope to keep it working. Request a free estimate or call 613-880-7679.
Will a new patio affect our lot grading?
It can, so the patio is built to fit the plan. City of Ottawa rules expect owners to keep the grades from the original grading plan and never cover swales or catch basins. We check what applies to your property and set patio height and slope to match.
How high can our new backyard fence be?
Generally up to 2.13 m in side and rear yards, under the City of Ottawa fence by-law. Gates may go 30 cm higher, and corner lots have lower limits near the intersection. We check what applies to your property before we build.
Are your estimates free?
Yes. Korvex Construction gives free estimates on site across Ottawa and the surrounding areas. Send the request form, or call, text or WhatsApp 613-880-7679, and we book a time to look at the property. The scope and the price follow in writing after the visit.
What should I send with my request?
A few photos of the area, close up and from a few steps back, where the property is, and a sentence on what you want done. That is enough for Korvex to set up the site visit. Measurements, material choices and budget can wait for the visit.
Can the final price go over the estimate?
Ontario’s consumer rules for home renovations set a limit. When a contractor gives an estimate, the final price cannot be more than 10% over it unless you agree to new work or a new price. The rule covers every home renovation contract in Ontario.
