Officer report

Main planning issues

The assessment considered the design, conservation area, neighbours, parking, biodiversity, wildlife, garden space and protected trees.

“Wildlife considerations 7.5.1 Section 40 of the Natural Environment and Rural Communities Act 2006 requires Local Planning Authorities to have regard to the purpose of conserving biodiversity. This is further emphasised by regulation 3(4) of the Habitat Regulations 1994 which state that Councils must have regard to the strict protection for certain species required by the EC Habitats Directive.”

“The Local Planning Authority is not aware of any records of bats (or other protected species) within the immediate area that would necessitate further surveying work being undertaken. Amenity 7.6.1 Policy CP12 of the Core Strategy states that development should take into account the need for adequate levels and disposition of amenity and garden space.”

Officer report

Who spoke

A parish councillor spoke against the application, raising concerns about crossovers, parking, the boundary, windows and the street scene.

Committee discussion

Members questioned the crossover arrangements and noted that the conservation officer had no objection to the proposal.

“In response to the comment made by the speaker about the status of the original crossover, a Committee Member commented that the Highways Authority had raised the dropped kerb and therefore it had potentially been included in the plans in error. The Planning Officer clarified that the acceptability of the scheme was not dependent on the removal or closing up of the dropped kerb.”

“It was noted that the Conservation Officer had no objection to the proposal.”
