Hi Folks,
Good news! our full planning application has been approved for demolition and re-build!
Now the celebrations are over, I am struggling with one of the planning conditions as follows:
"Condition. The access shall be constructed with adequate drainage measures to prevent surface water runoff onto the adjacent public highways, in accordance with a scheme submitted to and approved in writing by the Local Planning Authority.
Reason. To prevent surface water discharging to the highway."
The problem is that the plot is at a higher elevation than the highway and the existing access (tarmac over concrete) has a steep gradient towards the highway.
Our plans have stated that we will reduce this gradient but it will still slope down towards the road.
To compound the issue, another condition states that "a metalled surface must be applied for 5m back from the highway".
There is a steep banked grass verge each side of the entrance so no real possibility of a soakaway near the bottom of the slope. Presumably I am not allowed to connect to the rainwater drain on the edge of the highway?
I have attached a photo of the existing entrance.
My questions are:
1) Is this a pre-commencement condition that must be discharged before work starts on site?
2) How can I solve the issue of drainage at the bottom of the slope when there is nowhere to discharge water to?
3) Can a permeable surface be classed as a metalled surface?
4) Is a permeable surface on the slope likely to satisfy the surface drainage requirement?
Many thanks for any advice!
