The working group debated which technical items should remain in the bylaw and which should be deferred to the regulations. Members reached consensus on a two‑part approach: keep fundamental requirements (for example, the volumetric minimum) in the bylaw but place prescriptive design criteria, submission details and inspection timing in the regulations.

Key procedural/design items discussed:
- Plot plans and test pits: the group agreed test pits and their locations should appear on the plot plan submitted with applications. The location and required soil information (for example, water table level) will be specified in the regulations where they can be updated without retabulating the bylaw.
- Designer qualifications: the working draft will require engineering designs ‘‘as required’’ (that is, professional‑engineer (PE)‑stamped designs for projects above thresholds defined in the regulations). The plot plan itself may be prepared by a registered land surveyor, but the stormwater design and as‑built drawings will be prepared and certified by an appropriate professional (PE) for projects that trigger design-level review.
- As‑built drawings: the bylaw text will require as‑built drawings to accompany a certified plot plan and to demonstrate that stormwater systems were constructed in accordance with approved plans. The as‑built submission will be stamped by the responsible design professional where required.
- Inspections: the group adjusted language to change some proposed “shall” inspection language to “may” in the bylaw and move inspection staging specifics into regulations. This creates regulatory flexibility to require inspections at certain construction stages without changing bylaw text.
- Small projects and flexibility: members sought to preserve a path for less‑onerous review of small projects; the regulations will lay out objective thresholds (area triggers, units) identifying when a PE design is required.

Why it matters: the design and documentation rules determine who must hire engineers, what must be shown on plans, and when the town will inspect work — all of which affect project cost and permitting timelines. By moving prescriptive content to regulations the town preserves the bylaw’s policy floor while giving staff the ability to adapt technical submission requirements.

Ending: Staff will draft regulation language that specifies test pit protocols, plot‑plan content, when a PE is required, and inspection staging. The working group will review the proposed regulation text at a subsequent meeting.
