Why it was refused

  1. There are insufficient details to satisfy the condition as follows: o No details have been provided regarding design exceedance routes o Calculations should utilise a CV value of 1, a climate change value of 45% and the latest FEH data. o All infiltration features should have a half drain time of less than 24 hours. o Details relating to water quality have not been provided. o Evidence of communication with the water authority with regards to foul water discharge. o Management and Maintenance plan for the foul pumping station is required.
  2. The proposed retaining wall prohibits some of the swept path tracking shown. This issue needs to be addressed.
  3. There are insufficient details to satisfy the condition as follows: o Further justification regarding the assessment of the former sand pit and historical ground workings, including the evidence relied upon in reaching the conclusion that these features do not present a potential contamination concern. o In addition, Section 7.1 of the report summarises the site history as excavation activities occurring circa 1963-1974. However, earlier sections of the report and the supporting map records identify sand pit from significantly earlier periods. I thereby hereby REFUSE your application.

From the council's decision notice.
