Services — Creek Restoration, Erosion Audits and Stormwater Mapping

Service one

Deliverable: restoration plan
Field days: four to eight
Output: drawings and build order

Creek Restoration Plans

A creek restoration plan begins with a reach boundary that everyone agrees on. We mark the upstream and downstream limits, photograph every crossing and record the bed material at fixed intervals, then draw the channel as it is before proposing anything. That first drawing is often the most useful page in the document, because it ends the argument about what the creek looked like before the last storm.

The plan then sets the target condition. For an urban reach this usually means a wider low flow channel, a graded bank at a stable angle and a shaded buffer that can survive a mown lawn next door. For a rural reach the target is often a fenced buffer and a set of riffles that hold gravel through high water. We describe both conditions in the same measured terms so a crew can compare the cost of each option.

The build order is the part clients read first. It breaks the work into phases that can each be funded and finished in one season, with a note on what happens if phase two waits a year. A plan that cannot be paused is a plan that cannot be approved, so we always leave the channel in a stable state at the end of every phase.

Service two

Deliverable: ranked failure list
Field days: two to three
Output: audit sheets and map

Erosion Audit Walks

An erosion audit is done on foot, slowly, with two people who do not talk over each other. One walks the top of the bank and the other walks the toe, and both fill the same sheet so a disagreement about a slumping face is caught in the field rather than in the office. We record the height of the undercut, the exposed root depth, the toe position and the distance to the nearest fixed asset such as a trail, a fence post or a road shoulder.

The walk produces a ranked list rather than a single score. A long shallow scour that threatens nothing sits lower than a short vertical face under a driveway culvert, even if the scour moves more soil. Ranking by consequence keeps the repair budget honest, and it gives a council a defensible answer when a resident asks why one bank was fixed before another.

Each failure on the list carries a photograph taken from the same station and angle as the previous audit, so the next visit can be compared without guesswork. We also note the likely cause where it can be seen, because a repair that ignores the outfall above it will fail again within two seasons.

Service three

Deliverable: stormwater network map
Field days: three to five
Output: outlet register

Stormwater Mapping Sessions

A mapping session traces every pipe, ditch and swale that delivers water to the reach under study. We start at the creek and work uphill, opening each outfall to record its size, its material and the condition of the headwall. Where an outlet is buried or hidden, we use a simple dye trace in dry weather to confirm which pipe feeds it, and we record the result with a short note and a photograph.

The map is drawn in a shared workspace during the session, with the client team in the room, so the knowledge is not carried away in one persons notebook. Every outlet is labelled with its owner, which is often the single most useful field on the whole map. Ownership decides who pays for a repair and who is allowed to change a pipe, and that question stalls more restoration programs than any technical problem.

The session ends with a register that lists each outlet, its catchment, its condition and the recommended action. The register is written to be handed to a drainage engineer without rewriting, and the map is exported in an open format so it can be printed for a site trailer or loaded on a tablet in the field.

Service four

Deliverable: planting scheme
Field days: one to two
Output: species list and spacing plan

Riparian Planting Schemes

A riparian planting scheme settles the strip of ground between the top of the bank and the land use behind it. We measure the strip, note the sun angle and the soil moisture, and choose a species mix that will strike without irrigation. In most Niagara creeks that means a willow and red osier base with sedge and rush at the wet edge, plus a few larger stock trees for shade where the channel is wide.

Spacing is set by maintenance, not by appearance. A scheme that a single steward can weed and water in the first two summers is more likely to survive than a dense grid that needs a crew every week. We therefore write the scheme in bands, with a clear note on which bands can be left to natural regeneration once the willows have rooted.

The scheme also names the maintenance windows and the level of browsing protection each band needs. Deer pressure on a new willow cutting can undo an entire season, so the plan says plainly where guards are required and where a simple brush pile will do. A planting list without a maintenance note is only a wish list, and we do not issue wish lists.

Service five

Deliverable: flow record
Field days: five to seven
Output: gauge chart and notes

Flow Monitoring Weeks

A flow monitoring week installs a staff gauge and a small pressure sensor at each fixed station and reads them twice a day. We choose stations at a stable section with a clean straight run, so a single reading can be converted into a discharge figure with a simple rating curve. The curve is built from a handful of manual measurements taken during the week, and every measurement is kept so the curve can be checked later.

The week is timed to catch a storm if possible, but it is not wasted if the weather stays dry. A dry week establishes the base flow and shows how quickly the creek falls after a small rain, which is exactly the information a stormwater model needs. We deliver a chart of stage against time, a short table of peak readings and a plain note explaining what the pattern means for the reach.

Where a client already owns sensors, we can adopt them into the same record and check their calibration against our manual readings. Adopting existing gear is often cheaper than a fresh install, and it respects the work a volunteer group may have done for years before the program had a budget.

Service six

Deliverable: grant application draft
Field days: none
Output: scope, cost table and evidence pack

Grant Application Drafts

The grant application draft assembles the work of the previous five services into a document a review panel can follow without a site visit. It opens with the reach and the problem, states the proposed works in measured terms and ties each cost line to a drawing or a field note. Reviewers remember a proposal that can point to its own evidence, and that habit of cross referencing is what we build into every draft.

We write the draft in plain language and keep the technical detail in an appendix. A council member should be able to read the first two pages and understand what will change on the ground, while an engineer should be able to open the appendix and check the numbers. The same document serves both readers because the structure carries them to different depths.

The draft also includes a monitoring commitment the town can actually keep. A promise to sample daily for five years is not credible for a volunteer group, and a panel knows it. We propose a schedule matched to the resources we have seen, then note what extra funding would buy. A realistic commitment is stronger than an ambitious one nobody can deliver.

How a program moves through the camp

Every engagement follows the same four stages, whether it covers a single reach or a whole subwatershed. The stages are short by design, because a survey that drags on loses the trust of the people who live along the bank.

Walk and record

We walk the reach with the client, record the conditions and agree the boundary before any plan is written.

Draft and check

A working draft goes back to the client within two weeks, and we check it against the field sheets line by line.

Build the evidence

Maps, flow charts and planting notes are assembled into one file that supports the funding case.

Hand over

Files are delivered in open formats with a short guide, so the client owns the work and can carry it forward alone.

Bring us a reach and a deadline

Tell us which stretch of creek is causing trouble, who owns the banks and when a funder needs an answer. We will reply with a one page scope and a fee range, usually within two working days.
