USING THE LATEST SOFTWARE AND MODELLING TECHNIQUES TO MAXIMISE DEVELOPMENT POTENTIAL.

In Wales, FCA are required for development sites located within Flood Zones B & C on the Welsh Government Development Advice Map. Betts Hydro prepare site specific FCA in accordance with Technical Advice Note 15 (TAN15) and in full consultation with the relevant statutory bodies.

We have provided FCA for Residential, Commercial, Retail, Leisure, Infrastructure and Industrial developments; with sites ranging from straightforward to highly complex, we also have the expertise to carry out hydraulic flood modelling which is often requested by Natural Resources Wales (NRW) or used to maximise the development potential of sites.

Based on our clients specific requirements we tailor our service provision to suit the scale and complexity of their brief to ensure we provide best value.

Hydrodynamic modelling can provide clarification as to the extent of floodplain and flood risk to an existing or proposed development, by providing a greater degree of accuracy than existing Environment Agency Maps due to more detailed levels information. Betts Hydro are experienced in producing 1D hydrodynamic models of watercourses and identifying the extents of floodplains.

We use a range of different specialist software packages to achieve this including HEC-RAS and Microdrainage; these models enable us to predict a range of statistics including; flood depths, velocities, inundation rates and flood hazard ratings. This can allow our clients to maximise the development potential of sites whilst safeguarding existing and proposed development from flood risk.

Based on our clients specific requirements we tailor our service provision

Betts Hydro can provide overtopping or breach analysis of defences, including coastal, to provide hazard mapping which is often required by the EA/NRW to investigate the potential flood risk posed by breaches of natural and man-made flood defences.

Based on our clients specific requirements we tailor our service provision to suit the scale and complexity of their brief to ensure we provide best value.

As a property developer making a significant investment in land, you want reassurance the site is risk free. You don’t want repercussions further down the line which result in unforeseen costs and worst still, being told the land is unsuitable for development.

We eliminate risk for you, ensuring you have peace of mind with your investment. We have a multi-disciplined team working for you, each with developer back grounds, meaning we appreciate not only the technical and engineering constraints and risks, but also the commercial and legal implications.

Our technical expertise and business acumen enable us to deliver strategic, technical and engineering solutions geared towards bringing commercial benefit to you. These unique qualities provide you with the reassurance you need, when arriving at your decision.

Technical Due Diligence services available to you include:

• Master planning
• Feasibility and conceptual design
• Statutory authority negotiations
• Cost/value engineering
• Planning application technical support
• Initial site validation
• Phase 1 desk study
• Fully comprehensive technical report and drawings

To get peace of mind with your land opportunity, contact a member of our team by emailing admin@betts-associates.co.uk or calling 01244 288 178.

Betts Hydro provides pre-planning advice on flood risk and drainage matters to establish and deal with constraints as efficiently as possible. This can be key in influencing the proposed planning layout and in turn can affect land value. We provide robust drainage strategies to Local Planning Authorities to enable the most sustainable foul and surface water drainage solutions to be achieved. By considering flood risk and drainage at an early stage we can provide a considerable cost benefit to our clients.

Betts Hydro team of Infrastructure Engineers are experienced in foul water, surface water and highway drainage design to both a private and adoptable standard. We can provide basic preliminary drainage layout ‘concept’ plans through to complete detailed drainage solutions; including calculations, detailed design drawings and packages for Building Control review or submission for adoption (S104, S106 and S185).

We use Microdrainage for our detailed drainage designs and this is widely recognised in the UK as the industry standard. All of our designs are prepared using the latest AutoCAD or Civils 3D software.

We prepare drainage designs for sewer requisitions and adoption procedures, and offer an independent technical review service to audit drainage designs prepared by others. We liaise with Water companies, Natural Resources Wales, the Environment Agency, Canals and Rivers Trust, Internal Drainage Boards, Local Planning Authorities and Lead Local Flood Authorities.

We undertake Land Drainage Consent and discharge consent applications with the relevant authorities; prepare Environmental Permit applications; design adoptable standard foul and surface water pumping stations; specify septic tanks and package treatment plants; undertake surface water Soakaway designs; foul water drainage fields; surface water Outfall headwall and culvert design; specify flow control devices and oil interceptors.

Betts Hydro can help you satisfy the requirements for the Code for Sustainable Homes and obtain credits where appropriate for both; SUR1: Management of surface water run-off and SUR2: Flood risk.

We can also undertake Surface water Run-off and Storm water storage calculations to help establish drainage design criteria.

BREEAM addresses wide-ranging environmental and sustainability issues and enables developers, designers and building managers to demonstrate the environmental credentials of their buildings to clients, planners and other initial parties.

Betts Hydro can help you satisfy the requirements for POL3: Surface Water Run-Off (BREEAM 2014), to enable planning requirements and/or sustainability standards to be achieved.

Betts Hydro undertake Soakaway Testing in accordance with the BRE365 to allow accurate assessment of the likely effectiveness of infiltration drainage solutions such as Soakaways or Infiltration Basins. The testing is undertaken in accordance with the requirements of the Local Authorities and Water Companies; detailed design of infiltration drainage solutions is a service we also provide.
