ACCON carried out comprehensive flood risk, noise
and air quality assessments for the proposed
redevelopment of land at 8-12 The Broadway,
Bedford. The proposed development is for a
Specialist Residential Care scheme. The purpose of
these assessments was to determine to what
extent the environmental issues constrain the
residential development of the site.
The flood risk assessment identified that the
development site is within Flood Zone 1 and the
Sequential Test suggests that the proposed
development is appropriate for the site. Further
investigations identified that flood risk from all
sources is low and that the site would be safe from
flooding. Additionally, the development proposals
will result in a decrease in the impermeable area of
the site and would therefore decrease storm
runoff.
A noise assessment followed the CRTN shortened
methodology to assess the road traffic to
determine to what extent noise constrains the
development of the site. The subsequent
calculated freefield noise levels placed the
development in Noise Exposure Category C during
the day and Category B at night. In order to
mitigate noise from the aircraft and road traffic it
was recommended that the window system should
have a minimum SRI of 32 dB(A). Calculations
showed that with this level of noise reduction the
internal noise levels within habitable rooms would
meet the internal noise levels recommended in BS
8233 and WHO guidelines.
The development site itself is within an Air Quality
Management Area. The detailed air quality
assessment determined the overall levels of
hydrocarbons, nitrogen dioxide (NO2) and
particulates (PM10) in the vicinity of the site.
Verified predictions indicated that within the
development site the air quality limits would not
be exceeded. The predictions also indicated that
the impact of traffic associated with the
development would be negligible.
