Paving your Front Garden or driveway.
Planning permission
From 1 October 2008 new rules apply for householders wanting to pave over
their front gardens.
You will NOT need planning permission if a new driveway uses permeable (or porous) surfacing which allows water to drain through, such as loose gravel, permeable concrete block paving or porous asphalt, or if the rainwater is directed to a lawn or border to drain naturally.
If the surface to be covered is more than five square metres planning permission will be needed for laying traditional, impermeable driveways that do not control rainwater running off onto roads.This applies to old concrete or tarmac driveways that you are covering or replacing with new concrete, patterned imprinted concrete, tarmac top coats, stone chipping overlays etc. Be careful if you are sold a stone overlay system as this product is merely covering an existing surface and does not demonstrate sustainable drainage and may have to be removed and replaced correctly to comply with the new regulations.
This legislation has been brought in to control surface water run-off and reduce flooding. Traditionally when we lay a driveway or pave a front garden we set the 'falls' or levels to take the surface water to existing gullies or out on to the road way, this can no longer be the case and a client or contractor must control run-off in a more sustsinable manner.
We can provide a solutions package to domestic and commercial specifications to control and attenuate surface water run-off. We can supply detailed schematics if planning permission is required.We also supply the required products and schematics for domestic and trade clients to control surface water run-off naturally, fully complying with the new planning regulations without the need to specify permeable paving blocks.
Another service that we offer is to prepare driveways and gardens for sustainable drainage, allowing you to allocate the traditional work to any suitable contractor.

Paving your Front Garden
Planning permission
From 1 October 2008 new rules have applied for householders wanting to
pave over their front gardens.
You will not need planning permission if a new or replacement driveway of any size uses permeable (or porous) surfacing which allows water to drain through, such as gravel, permeable concrete block paving or porous asphalt, or if the rainwater is directed to a lawn or border to drain naturally.
If the surface to be covered is more than five square metres planning permission will be needed for laying traditional, impermeable driveways that do not provide for the water to run to a permeable area.
You will NOT need planning permission if a new driveway uses permeable (or porous) surfacing which allows water to drain through, such as loose gravel, permeable concrete block paving or porous asphalt, or if the rainwater is directed to a lawn or border to drain naturally or if you demonstrate sustainable drainage.
Simply put you have to deal with the rainwater falling on your driveway, it cannot go down the drain as you traditionally understand it and it cannot fall to the road.This applies to driveways that are being replaced also.

Introduction to Flood Risk Assessment
In accordance with Planning Policy Guidance Note 25(PPG25), local planning
authorities must ensure that flood risk is taken into account as part
of the planning process for all new developments so as to reduce the risk
of flooding and the damage it causes.
Flooding is a natural process that poses a risk to people and property,
and the experience of recent years suggests that the incidence and frequency
of flooding may be escalating.
Flood Risk Assessments are required to accompany planning proposals to identify the threat of flooding for the proposed development and the measures by which the risk can be minimised or avoided. PPG25 sets out Government policy on minimising the flood risk to property and the environment, outlining specific issues that should be addressed.
Approach to Flood Risk Assessment
Combined Harvesters are able to provide clients with appropriate
and expert advice regarding the scope and detail of works required for
a Flood Risk Assessment that is determined by the scale and location of
the development.
The key components of a Flood Risk Assessment are identifying the source
of flooding, reviewing the flood history, deriving critical water levels
and identifying any influences on river hydraulics. Projects must assess
flooding from tidal, fluvial, groundwater, and on-site drainage sources
individually and in combination. River modelling may be required where
sufficient flood risk data does not already exist.
In addition to evaluating the direct risk of flooding the Flood Risk Assessment
covers a number of other factors such as loss of floodplain storage and
surface water drainage issues.
Development often imposes new land uses on an area, which in turn can increase the surface water runoff during a storm event. Drainage calculations establish storm runoff from the site, and assess the risk of flooding should the drainage system become restricted.
Having assessed the flood risk to a site, a series of alleviation measures and engineering options such as Sustainable Urban Drainage Systems (SUDS), on-site storage and compensation storage can be evaluated by which the risk can be avoided completely or mitigated within acceptable limits to avoid flooding on-site
