Members visited the site on 11 February 2020.
Michael Brown (objector), John) Dudding (applicant’s agent), Councillor Frank Morris (Cottenham Parish Council) and Councillor Neigh Gough (local Member speaking on behalf of himself and Councillor Eileen Wilson, the other local Member) addressed the meeting.
The case officer updated the Committee. Late representations had already been addressed in the report. The Local Highways Authority had now changed its recommendation to approval. Ecology and Urban Design Officers were supportive of the application.
In response to Members’ concern about ongoing management and maintenance of the drainage system, the Delivery Manager (Strategic Sites) said that these matters were not in the gift of the Local Highways Authority.
that this application was premature. The proposal was seconded and, following a short debate, the motion
was put to a vote on the basis of the application being against the
Village Design Statement, permeability with the adjacent site,
layout and the likelihood of the estate roads not being adopted.
The vote was five in favour of deferral (Councillors Heylings,
Milnes, Rippeth, Roberts and Heather Williams) and five against
(Councillors John Batchelor, Bradnam, Cahn, Fane and Wright). The
Chairman exercised his casting vote against deferral so the motion was lost.
By seven votes to three, the Planning Committee resolved to approve the application subject to the Conditions and informatives contained in the report from the Joint Director of Planning and Economic Development and, by five votes to one with three abstentions, to the addition of the following Condition:
“No development shall begin until a surface water drainage scheme for the site, based on sustainable drainage principles, has been submitted to and approved in writing by the Local Planning Authority. The scheme shall subsequently be implemented in accordance with the approved details before the relevant part of the
scheme (including all strategic elements which will benefit all dwellings) and that part which is particular to an individual dwelling shall subsequently be implemented in accordance with the approved details before an application is made for a final certificate for building regulation purposes and no dwellings shall be occupied unless the relevant part of the said scheme has been implemented to the reasonable satisfaction of the Local Planning Authority. The scheme shall be based upon the principles within the agreed Flood Risk Assessment (FRA) prepared by Enzygo (ref: SHF.1132.024.HY.R.001.G dated August 2016 and shall also include: -
i) Full calculations detailing the existing surface water runoff rates for the QBAR, 3.3 % Annual Exceedance Probability (AEP) (1 in 30) and 1% AEP (1 in 100) storm events.
ii) Full results of the proposed drainage system modelling in the above-referenced storm events (as well as 1% AEP plus climate change) , inclusive of all collection, conveyance, storage, flow control and disposal elements and including an allowance for urban creep, together with an assessment of system performance.
iii) Detailed drawings of the entire proposed surface water drainage system, including
levels, gradients, dimensions and pipe reference numbers.
iv) Full details of the proposed attenuation and flow control measures.
v) Site Investigation and test results to confirm infiltration rates.
vi) Details of overland flood flow routes in the event of system exceedance, with demonstration that such flows can be appropriately managed on site without increasing flood risk to occupants.
vii) Full details of the maintenance/adoption of the surface water drainage system.
viii) Measures taken to prevent pollution of the receiving groundwater and/or surface water.
The drainage scheme must adhere to the hierarchy of drainage options as outlined in the NPPF PPG.
(Reason - To ensure a satisfactory method of surface water drainage and to prevent the increased risk of flooding in accordance with Policy CC/8 of the adopted Local Plan 2018.)”
