Introduction<\/h2>\n\n\n\n<p><span data-contrast=\"auto\">Highway drainage assets are considered an integral component to operating a safe and well-maintained carriageway which is why they are included as part of the carriageway lifecycle plan.&nbsp; Highway drainage systems are installed to capture surface water run-off to alleviate flooding and protect the fabric of the road.&nbsp; Getting water off the carriageway quickly is important in that it not only makes the road surface safer for drivers but also helps reduce deterioration of the road.&nbsp; Water egress and ingress into the road surface, the pumping action of tyres and freezing thawing damages and weakens the road surface leading to the development of potholes and the need for routine maintenance of the surface course.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">Other objectives include preventing the formation of ice on the highway, elimination and preventing safety defects occurring on the carriageways, footways and cycleways, and preventing the ponding and flooding to buildings and commercial properties. The main responsibility is to ensure that the highway is available and safe to all users<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">This document should be read in conjunction with the current Devon Local <\/span><a href=\"https:\/\/www.devon.gov.uk\/floodriskmanagement\/\"><span data-contrast=\"none\">Flood Risk Management Strategy<\/span><\/a><span data-contrast=\"auto\">&nbsp; (FRMS). As a requirement of the Flood and Water Management Act 2010, there is a duty for Devon as the lead Local Flood Authority to develop, maintain, supply and monitor a strategy for local flood risk management. The FRMS identifies the role of various Risk Management Authorities in managing the risk of flooding from different sources. The highway authority has a responsibility for managing the risk of flooding from surface water <\/span><b><span data-contrast=\"auto\">originating on the highway. <\/span><\/b><span data-contrast=\"auto\">A table outlining roles and responsibilities of Risk Management authorities and others such as landowners is available in the FRMS.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The impact of climate change will mean that winters may become warmer and wetter, summers hotter and dryer, there may be more frequent and intense extreme weather events. The effects of flooding, storms and extreme heat will affect our highway infrastructure including drainage assets.&nbsp;&nbsp; Our historical drainage systems may not cope very well resulting in potential flooding on highways and properties adjacent to the highway. The Council need to invest in drainage assets to reduce the impact of potential flooding. Regular inspections and maintenance and cleaning of our drainage assets is vital.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">Due to global warming, heavy precipitation events are expected to increase in frequency and intensity under climate change. This will result in more extreme weather events such as flooding. This will cause damages to private &amp; commercial properties, highway asset infrastructures and potential risks to lives, livestock and pollution of rivers and other water courses. There are moral and financial reasons why we should be investing more in our drainage assets.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The impact of climate change is one of the many challenges facing communities across Devon.

This provides assurance that these assets are inspected and in good working order. Cleaning or cleansing activities are usually all that is required but if further defects exist these can be captured as part of the cyclic operation. Highway users can view the following website to discover when a gully was last cleansed and the maintenance frequency for the next cleanse <\/span><a href=\"https:\/\/www.devon.gov.uk\/roads-and-transport\/maintaining-roads\/managing-the-network\/flooding-and-drainage\/report-standing-water-flooding-or-blocked-drains\/\"><span data-contrast=\"none\">here<\/span><\/a><span data-contrast=\"auto\">.<\/span><span data-contrast=\"auto\">&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">However, a proactive cleansing regime can only go so far and with budget pressures the frequency of cleansing is a challenge to maintain. Drainage assets operate in a dynamic environment and individual assets can suddenly be overwhelmed by weather events. A reactive approach is also needed to ensure flooded roads and surface water issues are managed appropriately.

the drainage assets.&nbsp; Each year there is a planned cyclic approach to inspect and cleanse road gullies, and other drainage features. This is funded through the revenue budget. Provision is also made to address defects identified with drainage assets by ensuring drainage jetters and minor works gangs are available throughout the year. Regrettably the funding available is insufficient to address all defects, such as road ploughing, blocked drains, broken and stuck gully covers, so such repairs are prioritised on a local basis.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"none\">Demands for drainage improvement works such as renewal of drains or improved drainage systems are funded from the capital programme. Repairs of this nature are largely integrated with road surface and footway needs and the overall investment is determined by the level of funding available and the overall quantity and condition of roads in each local area.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"6-programme-development\">6.
