Hi just landed here - thanks. Lets leap straight into the drains! Looking at purchasing a plot with detailed pp. It's a garden plot, on a slope, down from the existing road. Currently the plot contains some kind of sewage treatment for the existing house up the hill. There are three chief areas of concern I need to deal with. Replacement drains system for the existing house (owned by the plot seller), drains for the new-build, and surface water drainage. Solutions for these haven't been included on the plans, but the LLFA have linked a strongly worded consultee comment to the planning consent :- Quote "I am not comfortable with this proposal but the FRA provides sufficient information for the LLFA to remove its objection, however the following should be noted: 1. The site is within the Critical Drainage Area. Land, the highway and property at a lower level than the proposed site has suffered flooding as a result of surface water runoff. The gradient of the land in the area of the site has contributed to the runoff problems suffered. 2. Due to the problems outlined the LLFA wishes to apply a stricter drainage standard than that proposed in the FRA. Currently a system designed to the 1 in 30 year standard. The LLFA requires that the proposed drainage system must be capable to contain and manage flows up to the 1 in 100 year peak rainfall event plus an allowance of 40% for the effects of climate change. Flow from this system must be restricted to no greater than 1.5 l/sec. revised calculations will be required. 3. Consideration must be given to ground stability and site investigations must be undertaken to ensure that the ground conditions are suitable for the proposed drainage system. If you are minded to grant this application please apply the following condition to the consent: Condition: No development approved by this permission shall be commenced until details of a scheme for the provision of surface water management and foul water treatment has been submitted to and approved in writing by the Local Planning Authority. The details shall include:- A description of the foul and surface water drainage systems operation Details of the final drainage schemes including calculations and layout Confirmation from South West Water Ltd that the foul network has sufficient capacity to cater for this development A Construction Environmental Management Plan A Construction Quality Control Plan A plan indicating the provisions for exceedance pathways, overland flow routes and proposed detention features A timetable of construction including a plan indicating the phasing of development including the implementation of the drainage systems Confirmation of who will maintain the drainage systems and a plan for the future maintenance and management, including responsibilities for the drainage systems and overland flow routes Thereafter, the approved scheme shall be implemented in accordance with the details and timetable so agreed and the scheme shall be managed and maintained in accordance with the approved details. Details of the maintenance schedule shall be kept up to date and be made available to the Local Planning Authority within 28 days of the receipt of a written request. Reason: To prevent the increased risk of flooding and minimise the risk of pollution of surface water by ensuring the provision of a satisfactory means of surface water control and disposal." They are not keen on the development are they? So who is the professional I should employ to deal with this challenge does 'Civil engineering groundworks and water management' cover it or is there a specific professional body that covers the skill set. Hope you can help. Dee
