You Suggested We Did

Gate in Montford Place be locked when closure of Kennington Road lifted on 24 June Gate closed and under LB Lambeth control. Gate now locked with a Universal Lock, acceptable to Emergency Services. Provision of information

  • n effectiveness of

acoustic enclosure Provided visual and audio presentation at CLG’s and Drop In Sessions. Review potential noise sources at Montford Place Logistics Base Jet Spray equipment moved and noise mitigated where

  • possible. Signage installed on worksite to remind workforce
  • f obligation to respect community close by.

Vibration from the site works causing vibration Vibration monitor installed, data shared with residents and a meeting had with resident and noise & vibration consultants. A new monitoring regime is to be put in place. Correspond with delivery drivers illegally using Montford Place as a rat run Contacted companies on behalf of the Community to request their drivers obey road rules and respect community.
