Our Services

A broad overview of potential concepts to aid in the land purchase.

An assessment of potential flood risks from all sources, in compliance with NPPF standards. The FRA would assess flood risks to the site from on and off-site receptors, along with suggested mitigation of additional surface water flows produced through the development of the site, to ensure that off-site flood risk is not increased.
A plan providing information on flood safety and details of emergency planning for sites located in Flood Zones 2 and 3 (also known as a Flood Management Plan).
An investigation in relation to new flood issues associated with existing drainage networks. Where necessary, an engineered flood mitigation solution can be provided.
Details on how to manage the additional surface water created by the development proposals on-site, in order to mitigate against the potential risk of on or off-site flooding.
An investigation in accordance with BRE 365 into the porosity of the ground to enable the appropriate selection of SuDS techniques, according to the drainage hierarchy.
A plan setting out the maintenance regime, responsible bodies and asset register for drainage solutions, with the use of SuDS to deliver the four core objectives (water quantity, water quality, amenity and biodiversity).
A construction phase surface water management plan, including the required maintenance regime and procedures.
A review of the site for appropriate access requirements that are compliant to local and national standards.
A Transport Assessment can be tailored to suit the level of development to include junction modelling, accident data review, growth projection and recommended mitigation as necessary.
Sets out the planned targets and incentives to deliver a sustainable development. A post-planning coordination role can also be provided.
Provision of the necessary technical information and professional support to discharge planning conditions in relation to flood risk, drainage, transportation and highway designs.
