AI-ASSISTED
This control plan was generated against Built AI's environmental controls knowledge base, the pre-commencement ecological survey, and the local-authority planning conditions. Each control is mapped to a specific receptor at this location. A pollution incident, ecological breach or noise exceedance triggers immediate work stop and ecologist notification.

Sensitive receptors at this location
The site is calibrated to the receptors and statutory obligations particular to this location. The control plan below is engineered to manage them, not a generic environmental schedule:
- River Marsh watercourse — 12m from worksite · SSSI buffer zone · water vole and otter populations recorded · trout fishery downstream.
- Schedule 1 breeding birds — barn owls and kingfishers recorded within 200m · vegetation clearance restricted to Sept–Feb only.
- Residential receptors — nearest properties at 80m · noise monitoring required · BS 5228 working hours mandatory.
- Listed bridge furniture — original cast-iron parapets adjacent to worksite · Grade II listed by association · physical protection required.
- Public footpath FP-23 — popular walking route · diversion required throughout works · disability access maintained.
- Archaeological potential — county archaeologist requires watching brief on excavation deeper than 1m.

Stop-work triggers
The following events trigger an immediate stop on works pending review. Each is non-negotiable: turbidity or sheen visible on River Marsh · pollution incident of any volume · noise exceedance >65 dB(A) at boundary monitor · sighting of water vole within exclusion zone · accidental clearance during breeding bird window · archaeological discovery during excavation. Each event triggers the corresponding statutory notification (Environment Agency, ecologist, county archaeologist) within their notification windows.
