Site Environmental Management Plan (SEMP)
What is a Site Environmental Management Plan (SEMP)?
What is a Site Environmental Management Plan (SEMP)?
The City of Westminster may include the requirement for a Site Environmental Management Plan (SEMP) within a conditional planning consent. The City of Westminster Code of Construction Practice (CoCP, February 2022) details the requirement for the preparation of a Site Environmental Management Plan (SEMP) for Level 1 and Level 2 sites.
The City of Westminster CoCP definition of Level 1 and Level 2 projects is as follows:
Level 1 projects: Large/strategic proposals that involve the creation of 100 or more new or additional residential units or the creation/ change of use of 10,000 sqm or more floorspace. These are projects that will have impacts on the direct neighbourhood and on the wider community. Level 2 projects may be ‘upgraded’ to Level 1 projects due to the sensitivity of the local environment, which can include proximity of noise sensitive receptors or cumulative impacts.
Level 2 projects: Developments involving the creation of 10 or more new build residential units, or buildings where the new build floorspace to be created is 1000 sqm or more, or any basement developments. Level 3 projects may be ‘upgraded’ to Level 2 projects due to the sensitivity of the local environment, which can include proximity of noise sensitive receptors or cumulative impacts.
The specific requirements of the Site Environmental Management Plan (SEMP) include the following:
Part A: General Site Information, to include information including programme of works, demolition and construction methodology, and liaison with the local neighbourhood
Part B: Traffic, Transport and Highways Management Plan, to include information including construction traffic arrangements, measures to ensure cycle safety, and the use of highway (for skips, scaffolding, gantries, pitlanes, etc.)
Part C: Environmental Management Plan, to include information including noise and vibration management plan, noise site risk assessment (LANAF methodology), noise, vibration, dust and air pollution mitigation measures, and dust risk assessment
Application for Section 61 consent, to include all relevant information as required by the application form including noise predictions
If the preparation of site and project specific construction noise and dust assessments are required to support the SEMP we are also able to produce these documents, more information can be found here,
