Grade and drainage review hold points

Seeding can finish the appearance of a surface while leaving an unresolved grade or drainage question underneath it. A hold point gives the project a defined moment to review that question before the next operation obscures the evidence or creates more reinstatement work. This Calgary Project Workbook helps an owner organize observations and obtain the relevant decision. It does not design a drainage solution, certify grades or authorize altering a swale, neighbouring boundary or stormwater connection.

Collect the applicable grade information

Ask the builder or responsible project representative for the documents that govern the landscape interface. Record titles, revisions and the area they address. Identify whether the ground being released is the same condition those documents describe. A plan in a folder is useful only when the team knows how it relates to the current work.

Calgary's City of Calgary — lot grading and positive drainage guidance explains positive lot drainage and the roles involved in grade confirmation. Consult the current municipal information and obtain appropriate professional help for work beyond the team's competence. Do not treat a planting contractor's site attendance as a substitute for the required grade review or certification.

Record water observations without declaring a cause

Mark ponding, visible flow routes, sediment deposits and changes near paths or downspouts. Record when the observation was made and the weather context. A low-looking patch on a dry day and water remaining after a particular event are different observations. Photograph from safe positions and identify the view on the site sketch.

Separate “water observed beside the path” from “the path caused the problem.” The second statement needs investigation. Include relevant construction or maintenance changes as context, labelled as unconfirmed where necessary. Do not test drainage by deliberately directing water toward a neighbour or an uncertain outlet. The review should begin with available evidence and an appropriate site assessment.

Define what the hold prevents

Name the affected operation and polygon. A hold might prevent final preparation over an unresolved interface while allowing unrelated work elsewhere. Make the boundary clear enough that the arriving crew can respect it. Avoid a general “drainage issue noted” entry that leaves everyone to decide whether application can proceed.

A hold does not itself prescribe remediation. If an assessment calls for changed grades, drainage works or another technical solution, define and authorize that work through the appropriate process. Update the planting scope afterwards rather than treating the change as incidental surface smoothing.

Protect drainage features during coordination

The City of Calgary — stormwater bylaws and drainage guidance page provides current municipal drainage and stormwater references. Use those resources when the work interfaces with swales, downspouts or storm infrastructure. Confirm the applicable requirements with the responsible authority or professional. An owner’s preference for a flatter lawn does not settle the acceptability of changing a drainage route.

Mark features that must remain identifiable and explain them to the people moving soil or setting boundaries. If a stockpile or access route obscures a feature, record the condition and obtain the needed review. Keep erosion and sediment concerns in the project’s relevant plan rather than assuming permanent vegetation will address every issue immediately after application.

Work through a side-yard hold

Suppose a narrow side yard has a proposed planting strip beside a new path. After rain, the owner observes water remaining at one location. The worksheet records the position, time, photographs and recent path work. It does not conclude that more soil or a drain is the correct repair. The responsible reviewer compares the condition with the applicable grade information and determines what further assessment is needed.

The planting team can understand exactly which strip is held and what decision is awaited. If the review changes the boundary or preparation scope, issue a revised drawing and quantity record. If work elsewhere proceeds, retain separate release histories. The example illustrates a controlled decision, not a drainage design or a criterion for how long water may remain.

If different people review the same concern, ask them to identify the exact information and area their decision addresses. A soil-preparation opinion may not answer a drainage-design question. Retain those distinctions in the record instead of presenting several comments as one combined approval. This helps the planting team understand the remaining limit of its release.

Close the hold with evidence and limits

Record who released the area, the information relied on, the date and any conditions. Preserve the original concern beside the decision so a later reviewer can understand the history. A verbal “looks fine” without scope or authority is difficult to interpret if the condition recurs.

At handover, explain features the owner must preserve and any unresolved observations requiring follow-up. Keep the record connected to later changes. Continue with photo evidence, work sequencing and the acceptance walkthrough.
