boyle local area plan 2012 - 2018 - Roscommon County Council

PART II: DEVELOPMENT STRATEGY 2012-2018 & BEYOND Chapter 3: Infrastructure & Services
Roscommon County Council will take cognisance of
the OPW’s Flooding Report and any future reports in
relation to flood risk for the Boyle area and remaining
County. Developments granted permission in areas
close to flood plains will contain measures to ensure
that the risks of flooding are minimised or eliminated.
3.4.2 Flood Risk & Protection Strategy
The Flood Risk & Protection Strategy aims to;
• Avoid development in areas at risk of flooding by
not permitting development in flood risk areas,
particularly floodplains, unless it is fully justified
that there are wider sustainability grounds for
appropriate development and unless the flood risk
can be managed to an acceptable level without
increasing flood risk elsewhere and where
possible, reducing flood risk overall;
• Adopt a sequential approach to flood risk
management based on avoidance, reduction and
then mitigation of flood risk as the overall
framework for assessing the location of new
development in the development planning
process; and
• Incorporate flood risk assessment into the process
of making decisions on planning applications and
planning appeals.
Policies for Flood Risk & Protection
Policy 15
Implement ‘The Planning System and Flood Risk
Management Guidelines for Planning Authorities’
2009 (DEHLG & OPW), and any future reports in
relation to flood risk for Boyle or County
Roscommon.
Objectives for Flood Risk & Protection
Objective 25
Require all significant development impacting on
flood risk areas to provide a Flood Impact
Assessment, to identify potential loss of floodplain
storage and how it would be offset in order to
minimise impact on the river flood regime.
Objective 26
Ensure all large scale developments provide
‘Sustainable Urban Drainage Systems (SUDS) as part
of their development proposals.
Objective 27
Within the Boyle LAP area, RCC shall;
• avoid inappropriate development in areas at risk
of flooding; and
• avoid new developments increasing flood risk to
buildings, including that which may arise from
surface run-off.
3.5 WASTEWATER SERVICES
3.5.1 Existing Context
In addition to drinking water treatment and
distribution, Local Authorities are also responsible for
waste-water collection/disposal and storm-water
management, including collection and disposal. The
drainage system whether separate or combined
collects foul sewerage, industrial effluent and
rainwater, all of which must be discharged or treated
whilst minimising flood risk or environmental
impacts. The development and expansion of the
County’s wastewater and surface water drainage
system is essential to the future sustainable
development of the County and to the improvement of
water quality within and adjoining Roscommon.
The Boyle wastewater network was extended under
the Mocmoyne Serviced Land Initiative during 2008
to service lands in the Mocmoyne area on the western
end of Boyle town. (See Maps 4a & 4b) The Boyle
Waste Water Treatment Plant (WWTP) is designed to
achieve an effluent of BOD5 = 25 mg/l, suspended
solids = 35 mg/l and phosphorous = 2mg/l. However,
the treated effluent is currently meeting the required
parameters, as set out in the April 2010 discharge
licence of BOD5 = 15mg/l, suspended solids = 25mg/l
and phosphorous = 2mg/1. The plant is designed to
provide Secondary treatment with phosphate removal,
sludge thickening and dewatering for a population
equivalent (PE) of 6,000. It is located approximately
1km northeast of Boyle town. The primary discharge
from the area is located approximately 23 meters east
of the treatment plant and discharges to the River
Boyle, a tributary of the River Shannon. There are no
secondary discharges from the area. The plant can be
increased to an ultimate design population equivalent
of approximately 9,000 within the current site.
Therefore, it is considered that the wastewater
treatment and disposal network has sufficient capacity
for the LAP period.
In 2001, upgrade works to the collection system and
wastewater plant were completed. The upgrade
included the following.
‣ Some previously unserviced areas were
provided with new foul sewers. Some of the
existing foul sewers have been revamped.
‣ The treatment plant has been upgraded to
include screening and grit removal, stormwater
