Why it was refused

The proposed development fails to demonstrate that it would provide safe and suitable access for all users and that it would not result in an unacceptable impact on highway safety or the operation of the adjacent car park, contrary to Policy SADM40 of the Site Allocations and Development Management Policies (2016), Policy CS25 of the Core Strategy (2013), and the National Planning Policy Framework. Insufficient information has been submitted to allow for a proper assessment of the potential impacts on parking provision and highways safety.
Insufficient information has been submitted regarding drainage arrangements, water treatment, and mitigation measures to address potential surface water runoff from the car wash associated water use. In the absence of this information, the applicant has failed to demonstrate that the proposed development would not increase flood risk to the surrounding area that already subject to drainage problems, and is therefore contrary to the NPPF, Policy CS16 of the Core Strategy 2013, and Policies SADM13 and SADM14 of the Site Allocations and Development Management Policies Plan 2016.

From the council's decision notice.
