   HBED 01 HBED 02 13.6.14 Home Based Economic Activity Home based economic activity is defined as small scale commercial activity carried out by residents of a house or persons main residence, being subordinate to the use of the house as a single dwelling unit and includes working from home. Proposals that adversely impact on existing residential amenity of the area by way of increased traffic, noise fumes, vibration, smoke, dust or odour will not generally be favourably considered. Following the outbreak of the Covid-19 virus in Ireland, the growing trend of people choosing to work from home became a necessity, either through e-working or through setting up a home-based economic activity. Applications for small-scale home-based economic activity in rural areas, where the occupants of the existing dwelling are employed at home will be considered on an individual basis. Such business would only be acceptable where this activity is very confined and further expansion proposals would be unlikely to receive favourable consideration. Home based economic activity should be sited either in converted existing farm buildings located adjacent to the main dwelling house or within the house where the use is compatible with the use of the dwelling as a home. Home based businesses, which wish to expand beyond the current location, will be required to locate in a town/village or other area suitable to the use proposed. The development of e-working and home-based business is also important as it may contribute to improving the quality of lives and help people achieve an improved work life balance. In addition, it also benefits the environment in terms of energy conservation, reduced commuting emissions, and reduced traffic congestion. Home Based Economic Activity Development Objectives It is a development objective of Cavan County Council to: That applications of this nature have regard to the following: l The use remains ancillary to the main residential use and the applicant continues to reside in the dwelling l The effects on the amenities of adjoining occupiers, particularly in relation to hours of work, noise and general disturbance. l Anticipated levels of traffic generated by the proposed development and the potential increased demand for parking l Arrangements for the storage of refuse and collection of waste l Activity which depends on visits by members of the public will be discouraged Applications may be subject to a temporary permission, in order to enable the Planning Authority to monitor the impact of the developmentDevelopment Management 459

   13.7 Development Management Standards 13.7.1 Flood Zones and Appropriate Uses The table below indicates the types of land uses that are appropriate in each of the Flood Zones identified within the Plan area, in accordance with the 2009 Flood Risk Management Guidelines for Planning Authorities and Departmental Circular PL2/2014 (or any updated/superseding legislation or policy guidance). Where developments/land uses are proposed that are considered inappropriate to the Flood Zone, then a Development Management Justification Test and site-specific Flood Risk Assessment will be required in accordance with The Planning System and Flood Risk Management Guidelines 2009 (and as updated). Note (refer to Flood Risk Management Guidelines 2009 and ‘SFRA for the Cavan County Development Plan 2022-2028’ for additional detail): l Highly Vulnerable Development - Houses, schools, hospitals, residential institutions, emergency services, essential infrastructure, etc. l Less Vulnerable Development - Economic uses (retail, leisure, warehousing, commercial, industrial, non-residential institutions, etc.), land and buildings used for agriculture or forestry, local transport infrastructure, etc. l Water Compatible Development - Docks, marinas, wharves, water-based recreation and tourism (excluding sleeping accommodation), amenity open space, sports and recreation, flood control infrastructure, etc. Flood Zones Overall probability Planning implications for land uses Highly Vulnerable Development Less Vulnerable Development Water Compatible Development Flood Zone A Highest Inappropriate – if proposed then Justification Test and detailed Flood Risk Assessment is required Inappropriate – if proposed then Justification Test and detailed Flood Risk Assessment is required Appropriate – screen for flood risk Flood zone B Moderate Inappropriate – if proposed then Justification Test and detailed Flood Risk Assessment is required Inappropriate due to climate change – if proposed then Justification Test and detailed Flood Risk Assessment is required Appropriate – screen for flood risk Flood Zone C Lowest Appropriate - detailed Flood Risk Assessment may be required Appropriate - detailed Flood Risk Assessment may be required Appropriate – screen for flood risk Guidelines for Planning Authorities November 2009 The Planning System and Flood Risk Management20Cavan County Development Plan 2022-2028 460

   13.7.2 Structural and Non-Structural Risk Management Measures in Flood Vulnerable Zones Applications for development in flood vulnerable zones shall provide details of structural and non-structural risk management measures to include, but not be limited to specifications of the following: 13.7.2.1 Floor Levels In areas of limited flood depth, the specification of the threshold and floor levels of new structures shall be raised above expected flood levels to reduce the risk of flood losses to a building, by raising floor heights within the building structure using a suspended floor arrangement or raised internal concrete platforms. When designing an extension or modification to an existing building, an appropriate flood risk reduction measure shall be specified to ensure the threshold levels into the building are above the design flood level. However, care must also be taken to ensure access for all is provided in compliance with Part M of the Building Regulations. Where threshold levels cannot be raised to the street for streetscape, conservation or other reasons, the design shall specify a mixing of uses vertically in buildings - with less vulnerable uses located at ground floor level, along with other measures for dealing with residual flood risk. 13.7.2.2 Internal Layout Internal layout of internal space shall be designed and specified to reduce the impact of flooding [for example, living accommodation, essential services, storage space for provisions and equipment shall be designed to be located above the predicted flood level]. In addition, designs and specifications shall ensure that, wherever reasonably practicable, the siting of living accommodation (particularly sleeping areas) shall be above flood level. With the exception of single storey extensions to existing properties, new single storey accommodation shall not be deemed appropriate where predicted flood levels are above design floor levels. In all cases, specifications for safe access, refuge and evacuation shall be incorporated into the design of the development. 13.7.2.3 Flood-Resistant Construction Developments in flood vulnerable zones shall specify the use of flood-resistant construction aimed at preventing water from entering buildings - to mitigate the damage floodwater caused to buildings. Developments shall specify the use of flood resistant construction prepared using specialist technical input to the design and specification of the external building envelope – with measures to resist hydrostatic pressure (commonly referred to as “tanking”) specified for the outside of the building fabric. The design of the flood resistant construction shall specify the need to protect the main entry points for floodwater into buildings - including doors and windows (including gaps in sealant around frames), vents, air-bricks and gaps around conduits or pipes passing through external building fabric. The design of the flood resistant construction shall also specify the need to protect against flood water entry through sanitary appliances as a result of backflow through the drainage system. 13.7.2.4 Flood-Resilient Construction Developments in flood vulnerable zones that are at risk of occasional inundation shall incorporate design and specification for flood resilient construction which accepts that floodwater will enter buildings and provides for this in the design and specification of internal building services and finishes. These measures limit damage caused by floodwater and allow relatively quick recovery. This can be achieved by specifying wall and floor materials such as ceramic tiling that can be cleaned and dried relatively easily, provided that the substrate materials (e.g. blockwork) are also resilient. Electrics, appliances and kitchen fittings shall also be specified to be raised above floor level, and one-way valves shall be incorporated into drainage pipes. 13.7.2.5 Emergency Response Planning In addition to considering physical design issues for developments in flood vulnerable zones, the developer shall specify that the planning of new development also takes account of the need for effective emergency response planning for flood events in areas of new developments.Development Management 461

   Applications for developments in flood vulnerable zones shall provide details that the following measures will be put in place and maintained: l Provision of flood warnings, evacuation plans and ensuring public awareness of flood risks to people where they live and work; l Coordination of responses and discussion with relevant emergency services i.e. Local Authorities, Fire and Rescue, Civil Defence and An Garda Siochána through the SFRA; and l Awareness of risks and evacuation procedures and the need for family flood plans. 13.7.2.6 Access and Egress During Flood Events Applications for developments in flood vulnerable zones shall include details of arrangements for access and egress during flood events. Such details shall specify that flood escape routes have been kept to publicly accessible land. Such routes will have signage and other flood awareness measures in place, to inform local communities what to do in case of flooding; and this information will be provided in a welcome pack to new occupants. 13.7.2.7 Further Information Further and more detailed guidance and advice can be found at http://www.flooding.ie and in the Building Regulations.Cavan County Development Plan 2022-2028 462
