Scheme Background
Porth is noted as an area of high surface water and ordinary watercourse flood risk based on Natural Resources Wales’s (NRW) Flood Risk Assessment Wales (FRAW) maps. The community of Porth is also identified as the 33rd most at risk community for ordinary watercourse and surface water flooding in Wales according to the Communities at Risk Register (CaRR) 2024 which was developed by NRW to provide an objective means of identifying risk and prioritising flood risk management activities at a Wales-wide, community level.
The consequences of being a high-risk flood area have been particularly evident over the past 5 years, with Storm Dennis in 2020 and Storm Bert in 2024 leading to widespread internal flooding across the community.
Proposed Scheme Objectives
- Reduce risk to life by reducing the number of people exposed to risk of flooding of significant depth and velocity.
- Reduce community disruption by reducing the amount of residential and commercial property exposed to flood risk.
- Result in no detriment to downstream receiving River/Watercourse
- Improve community resilience to flood events and climate change, promoting sustainability and wellbeing.
- Deliver a preferred option that works with natural processes and promotes green infrastructure.
- Enhance local biodiversity and support the resilience of ecosystem services.
- Improve the resilience of flood risk assets against climate change - Promoting accessibility and low maintenance requirements.
- Reduce the impact of climate change – mitigating the extent of the projects carbon footprint.
- Improve community wellbeing through the enhancement of local amenity.
Proposed Scheme Description
The Council proposes to carry out land drainage improvement works on an unnamed ordinary watercourse that originates at Turberville Road and conveys to its outfall within the River Rhondda.
The location of these works will take place in Turberville Road, Packers Road, and Aber-Rhondda Road in Porth.
The works are intended to upgrade the culvert barrel across the downstream network to ensure the capacity of the system is appropriately sized to accommodate the Q100 (1 in 100 year) + 30% climate change event. To facilitate this enhancement, the proposed works will also include a section of below ground storage to reduce the extent of downstream upgrades required where the ordinary watercourse access is restricted by terrace properties and garage/extension build overs. These improvement works also form part of council’s Flood Action Plan, which has been designed to actively manage the risk of surface water and ordinary watercourse flooding to properties within RCT.
Environmental Impact Assessment (Land Drainage Improvement Works) Regulations 1999 Notice
The Council does not intend to prepare an environmental statement in respect of the proposed improvement works. With reference to Schedule 2 of the Environmental Impact Assessment (Land Drainage Improvement Works) Regulations 1999, the reasons for not intending to prepare an environment statement are that, considering the characteristics of the improvement works, the environmental sensitivity of geographical areas likely to be affected by the improvement works and the type and characteristics of the potential impact on the environment of the improvement works, it is considered that the proposed works will not have a significant effect on the environment. A notice for these works was served on the 04th April 2025. View the Environmental Impact Assessment (Land Drainage Improvement Works) Regulations 1999 Notice
