To Planning
From: Martina Smith, Environment Section
Ref: 26/60115 St Macartans Diocesan Trust, Connabury/Onomy, Castleblayney, Co.
Monaghan
Agent: McGuigan Architects
Permission to extend existing graveyard to include access roads, plot locations, columbarium
wall, drainage & all associated works at St.Mary’s Church, Connabury/Onomy, Castleblayney,
Co.Monaghan.
The proposed extension to the existing graveyard site comprises an area of 0.9 hectares, the site
is located within the Lough Muckno Catchment area. Lough Muckno has been classified as
Moderate Status, 2019-2024 with an WFD objective of restore to Good status. The site lies within
the outer source protection area for the Inniskeen & Cavanhill PWS and is located within 400m
of the lake shore and an outdoor water sports amenity area. The site is located on an area of low
groundwater vulnerability which is underlain by a poor locally important aquifer.
It is important that adequate measures are in place for the construction and operational phase
on the development to ensure no impact on the receiving waters. The application does not
include a water protection checklist or any site investigations carried out to determine the
suitability of the land for use as a graveyard or to assess the impact of the proposed development
on receiving surface and ground waters.
The application includes some details of the proposed storm water treatment system to include
an attenuation chamber, a hydrobrake flow restrictor and a class 1 hydrocarbon interceptor for
treatment of storm waters prior to discharge to a neighbouring site however, nature-based
solutions do not appear to have been incorporated into the design.
I therefore recommend that the following information is requested from the applicant:
1. A fully completed water protection checklist.
2. A hydrogeological report carried out to assess the potential impact of the proposed
development (construction and operational phases) the on receiving surface and ground
waters. This report shall identify potential receptors and shall include a soil investigation
survey of the land to determine its suitability for use as a burial ground. The report shall
be prepared by a suitability qualified person.
3. Revised proposals for the storm water drainage system to take account of the
Department of Housing, Local Government and Heritage guidance document on Nature-
based solutions for the management of rainwater and surface water run-off in urban
areas.
