Informatives
Drainage Informatives:
1. Flood resilience should be duly considered in the design of the new building/s or
renovation. Guidance may be found in BRE Digest 532 Parts 1 and 2, 2012 and BRE
Good Building Guide 84.
2. Developments should have floor levels set higher than the recorded flood level or a minimum of 300mm above proposed ground level.
3.Surface Water Discharge From Brownfield Site:
There should be no increase in surface water discharge from the site to existing sewers / watercourses. On site surface water attenuation will therefore be required if drained areas to existing sewers / watercourses are to be increased.
A 30% net reduction to existing peak discharge (up to a 1/100 yr storm + 40% CC) will be required if the site is being re-developed. A full justification will be required where the development cannot achieve the 30% betterment on the existing run-off rate.
4. On Site Surface Water Management:
The site is required to accommodate rainfall volumes up to 1 in 100 year return period (plus climate change) whilst ensuring no flooding to buildings or adjacent land.
The applicant will need to provide details and calculations including any below ground storage, overflow paths (flood routes), surface detention and infiltration areas etc. to demonstrate how the 100 year + 40% CC rainfall volumes will be controlled and accommodated.
Where cellular storage is proposed and is within areas where it may be susceptible to damage by excavation by other utility contractors, warning signage should be provided to inform of its presence. Cellular storage and infiltration systems should not be positioned within highway.
Guidance on flood pathways can be found in BS EN 752.
5. Whereby a private maintenance arrangement is proposed and the development is
unlikely to remain under single ownership or within a single curtilage over its lifetime a condition will require a satisfactory legal agreement to be drawn up to provide for
inspection and maintenance of the proposed surface water drainage scheme. This legal agreement is required BEFORE the first occupation of any dwelling or building on the site. Over the lifetime of the development an agreement must include the following:
a) A detailed operational maintenance plan;
b) Physical access arrangements for maintenance, and establishment of legal
rights of access in perpetuity, prior to the commencement of any phase of the
development;
c) A financial revenue plan clearly setting out how funding for maintenance is to
be raised over the lifetime of the development;
d) A whole life cost analysis for capital maintenance over the lifetime of the
development. Any values should be based on the current HM Treasury Present
Value (PV) Discount Rate. Assumptions about the expected useful life of
materials should be included in any such analysis; and
e) Details of financial surety to ensure long-term maintenance and capital
maintenance costs of apparatus. It is for the developer to demonstrate that a
suitable financial underwriting arrangement is in place.
Positive and Proactive Statement
Whilst the applicant did not enter into any pre application discussions with the Local Planning Authority, the proposals were in accordance with the principles of the National Planning Policy Framework and did not require any alterations or modification.
