The final report in the flooding which took place in the City on 13th August 2018 has been published.
More than 40mm of rain fell on large areas of the City in just over 15 minutes on the 13th August 2018, the intense nature of the storm led to significant areas of the cities road network being impacted by standing water and drainage systems were unable to cope.
Several properties were internally flooded and outbuildings and gardens of a greater number of properties were similarly affected.
Surface water flooding occurs when rainfall exceeds the capacity of open or piped systems or cannot soak into the ground. It typically occurs because of high intensity rainfall and can be aggravated by pipe or ditch blockage.

The York Council report is well written and makes several suggestions for improvements It refers to ongoing problems in Haxby but more generally highlights the gully reconstruction and cleaning programme that has been taking place over recent months.
The August event, when 120mm/hr of rainfall were recorded, is exceptional. Any event like this will cause some surface water accumulation but the City is now better prepared to deal with heavy rainfall in future.
One of the recommendations in the report is that network of digital rain meters is installed across the city.
We understand that the Foxwood Residents Association have formally objected to the Councils plans to “replace” the children’s all-weather games area on Kingsway. The objection stems from the Councils proposal to build “fitness equipment” on Chesneys Field during the summer. The Association points out that no consultation has taken place over this proposal which could intensify the use of what is Public Open Space. When a similar idea was mooted 2 years ago, the preferred site for a fitness track was judged to be the Thanet Road Sports Area. The Association have suggested that the Council seek a partnership with the Acorn Rugby Club which could see a new 3G games area provided. Sport England have also objected to the Council’s plans
- The Yorspace proposals for the Lowfields site have been criticised by the local Drainage Board. They are asking for further details of how surface water runoff will be handled. They point out the fact that – for the whole site – water run off is likely to be more severe than occurs from the existing greenfield use. There are already some problems with flooding in the gardens of some properties in the Green Lane and Tudor Road area.
- Separately the Lowfields Residents Group has objected to plans which would see the number of off street parking spaces reduced near 108 Tudor Road. They are also concerned about the traffic implications of building a new access road onto the Lowfields site
NB. The contract for “enabling works” at Lowfields was awarded to NMCN. It is valued at £260,000. The end date for the contract is 19th April 2019.
Another update on the work being undertaken to prevent flooding in the York area is being considered on 3rd December.
The report has been produced by the Environment Agency.
Details are also provided on the alleviation plans for the Clementhorpe part of the City.
Regular updates have been provided since the flooding in late December 2015 which followed an intense period of rainfall across November and December due to the impacts of Storms Desmond and Eva.
Record river levels were observed in many river catchments across the north of England. More than 4000 homes and 2000 businesses flooded across Yorkshire with 453 properties and 174 businesses flooded in York.
Funding has been allocated to the Environment Agency (EA) following the floods to renew existing and provide new flood defences across the city, £17m has been allocated to the Foss Barrier improvements and £45m to the wider flood defences across the city
The recent surface water flooding which we saw a few weeks ago is being addressed by the Council. In a report to be considered next week, they say that their Flood Risk Management Team is currently investigating the consequences of the 13th August 2018 storm which affected the city. More than 40mm of rain fell on the city in just over 15 minutes, Rainfall rates more than 120mm/hour were recorded.
The problems seemed to be exacerbated by blocked gullies. This was a problem on some roads where footpath gullies were obstructed.
A policy adopted by the then Labour controlled Council 5 years ago meant that gullies were cleaned only upon report. Due to this reactive cleanse policy in recent years, approximately 53% of drains have been found to be blocked upon attendance.
The Council says the revised gulley cleansing policy aims to proactively cleanse all gullies on the gritting network annually and all other assets are reactively cleansed following reports of issues. “There are more than 43,000 gullies in the CYC area and approximately half of these are on the gritting network”.
The Council has allocated funding, in the period up to 2020, which will allow the whole network to be surveyed, the development of an improved asset register and an effective proactive cleanse of each asset to be carried out. Over the whole programme, which started in 2015, the added investment will have ensured that in the region of 23,000 gullies were left in a free running state that were previously not draining effectively.
Additional gullies cleansed, and data recorded
|2018/19||2,468 (to date)|
However, more than 900 ‘non-runner’ assets have been identified where the gulley cleansing process could not ensure free drainage and significant engineering works (digging out) are required to improve them. None of the current defects were found to be in a location where property flooding could occur as a direct consequence of severe rainfall.
Separately the meeting will consider an update report from the Environment Agency on tacking river flooding issues across the City. The Agency is doing well in keeping residents briefed on the work that they are doing. They have now started a web site which builds on their communications plan tick here This complements the information “hub” that they established on Wellington Row.
Generally, the update says that work to improve flood defences is proceeding in line with the agreed timetable
The deluge that engulfed the City yesterday evening produced surface water flooding problems in many areas.
The Council says it is working hard to remedy problems. It asks residents to report issues to FRM@york.gov.uk or call the customer centre on 01904 551550.
These are couple that we reported yesterday.
The heavy rain in the City has subsided today but several rivers are still showing increasing levels. We recommend that residents check the river gauges regularly and in particular those located upstream of the City. There is still a lot of water to flow through.

Drivers faced another hazard yesterday as a large pothole developed on the A59 road works on the south bound side of Skip Bridge. The carriageway is single file, over the bridge, there at the moment. Some delays may be expected,.
Several Councillors including – Andrew Waller – toured their wards yesterday to identify areas where gullies might be blocked. Some surface water flooding was identified by Andrew in Osprey Close (run off from agricultural land), Westfield Place, Cornlands Road, St Stephens Rd., St Stephens Square and Gale Lane, Any blocked gullies have been reported for attention.
UPDATED – Flood warning no longer in place 1100hrs 18th Jan 2018
Anyone for a shower?
There are still too many blocked drainage gullies in parts of York. This mornings rain demonstrated the scale of the problem with flooding at the bottom of Hamilton Drive East a particular hazard. There were similar if less spectacular problems on Nigel Grove and Foxwood Lane. All have been reported for attention
