Land Use and Zoning Scotland 4 Minutes Read · published February 11, 2026 Flag of Scotland

Glasgow, Scotland faces varied flood risks and the city requires developers and landowners to address flood risk and drainage when proposing new development. This article summarises the council expectations for Flood Risk Assessments (FRAs), who enforces the rules, what mitigation measures are typically required, and the practical steps to apply, appeal or report non-compliance within Glasgow City Council’s planning framework.

Check site-specific flood maps early to avoid unnecessary design revisions.

Overview

Local planning decisions in Glasgow take account of flood risk, the Scottish Environment Protection Agency (SEPA) guidance, and Glasgow City Council planning policies. Applicants are expected to demonstrate that a development will be safe for its lifetime and will not increase flood risk elsewhere. For official guidance and local advice, consult Glasgow City Council and SEPA guidance directly via the council flood information and SEPA flood-risk pages Glasgow City Council - Flooding and flood risk[1] and SEPA - Flood risk management[2].

Requirements for Planning Applications

When a proposal is in a known flood-risk area or involves significant surface water or drainage changes, the council requires a Flood Risk Assessment (FRA) or drainage strategy submitted with the planning application. The FRA should assess risk, propose mitigation (flood resilient design, finished floor levels, sustainable drainage systems), and show maintenance arrangements.

  • Applicants: provide an FRA where a site is in or near flood risk zones.
  • Design: include Sustainable Drainage Systems (SuDS) and site-appropriate mitigation measures.
  • Evidence: include modelling, levels, and maintenance plans for drainage features.

Penalties & Enforcement

Enforcement of flood-related requirements falls to Glasgow City Council planning enforcement and building standards where breaches affect safety or contravene planning permissions. The council may require remedial work, issue enforcement notices or pursue prosecution for non-compliance.

  • Monetary penalties: not specified on the cited page; see the council enforcement contact for details and processes.
  • Escalation: first or continuing offences and any daily fines or increased penalties are not specified on the cited page.
  • Non-monetary sanctions: enforcement notices, stop notices, requirements to reinstate land, and court action are used; specific sanctions and thresholds are not specified on the cited page.
  • Enforcer and complaints: Glasgow City Council Planning Enforcement handles reports and inspections; use the council enforcement contact page to report suspected breaches Glasgow City Council - Planning Enforcement[3].
  • Appeals/review: routes of appeal and statutory time limits for challenge are not specified on the cited pages and applicants should follow the council guidance when notified of enforcement action.
If you receive an enforcement notice, act quickly as specified time limits may apply.

Applications & Forms

The FRA itself is normally submitted as part of the planning application package. The council publishes planning application forms, guidance notes and validation checklists; specific form names, fees and deadlines are set on the planning application pages and in fee schedules. Fee amounts and exact form numbers are not specified on the flood guidance page cited above.

  • Planning application: submit FRA and drainage details with the planning application as required by the validation checklist.
  • Fees: planning application fees apply; check the council planning fees page for current charges.

Practical Action Steps

  • Step 1: Check SEPA flood maps and the council’s flood pages early to determine if an FRA is required.
  • Step 2: Commission a qualified flood consultant to prepare an FRA and drainage strategy.
  • Step 3: Submit the FRA with your planning application and include maintenance plans for SuDS features.
  • Step 4: If you are contacted about enforcement, respond promptly and seek pre-application or planning enforcement advice.
