How Do I Use the Map?

In this section:

What's on the Map?

By default, the map shows traffic speed and the location of the Environment Agency's river gauges  (and during a flood warning any Flood Alerts). 

The road colours indicate the speed of traffic on the road.

  •     Green means there are no traffic delays
  •     Orange means there's a medium amount of traffic
  •     Red means there are traffic delays. The more red, the slower the speed of traffic on the road.

The colours of the river gauge pins each have a specific meaning as shown in the map legend.

Clicking on a gauge pin will open up a window of information taken from that gauge.

Please note the river gauges do not show the risk from flash flooding, however the flood alerts (when activated) will.

The larger Alert pin when clicked shows the current flood alert warning and the colour of the river shows the alert level at the time.

Alerts are live 24/7, straight from the Environment Agency. Alerts are updated every 15 minutes to keep you informed about flood risks in your chosen area.

There are several layers on the Eye on Calderdale map that are not activated by default.

Clicking the "What's on the Map?"  button at the bottom of the map will slide open the map legend panel. 

Clicking on each option opens up a explanation of what each layer or option means and they can be activated and deactivated using the tick box beside each. 


Other "What's on the Map" Options

Selecting the Flood Risk option will show the areas that have previously been at risk of flooding from rivers,

Local Traffic Disruptions show where known roadworks are happening and the severity of the disruption (clicking on a pin will show you further details of the work being carried out),

Alternative Routes and Diversions show possible bypass routes that can be used in the event of a flood. 

(NOTE: These routes are recommended for local access only with limited through route. NOT for vehicles exceeding 3.5 tonnes. These suggested routes DO NOT necessarily bypass other potentially flooded locations in the area.),

Reported Hazards show the pins placed there by other users (See Report a Hazard).

You can return to the map at any time by using the click to close option shown at the top right on the map legend or by moving the map.


Searching for a location

Use the search option in lower left-hand corner of the map to search for a postcode, town or city within Calderdale and check for hazards within that area.

To move the map (pan), simply click and hold your mouse, then drag the map. You can also use the arrow keys on your keyboard to move the map north, south, east, and west.

Zoom in and out by using the  zoom in zoom in zoom out â€‹zoom out buttons or slider in the top left corner of the map. You can also double click to zoom in, or use your mouse scroll or trackpad to zoom in and out.


Reporting a hazard

Clicking the "Report a Hazard" button will navigate you to the Report a Hazard page where you can help us make this website as useful as possible by marking hazards on our map to warn others.

For more information on reporting a hazard, click here.


How is information gathered?

Our interactive map uses a method called ‘crowdsourcing’ to gather accurate information – and sometimes even photographs – from members of the public just like you.  Anybody with access to the internet can report on a hazard they see by marking it themself on our map, even adding photos or comments if they want to.  This helps us provide the most detailed and up-to-date information possible, as well as helping us to quickly alert the most appropriate authorities. 

The pins, comments and attached photos remain active and visible on the map for 24 hours unless removed by a site moderator before then.

What else is on the home page?

Check your Flood Risk - a link to the page is located above the map (for more details on how to use this page, see section below)

Alerts - for more details on the various alerts shown on the home page and what they mean, see below

Record Recent Flooding - located beneath the map is a link to a reporting facility to enable you to tell us about your flooding experience. This form is for the purpose of collecting data on large scale flood events to aid in conducting the statutory Section 19 Flood Investigation as per the Flood and Water Management Act. This form should not be used to report existing flooding.

Facebook and Twitter Links - shown near the bottom of the page in a blue scroll box are the various related Facebook and Twitter feeds that may be of assistance with keeping up to date on the current situation including the Calder Valley Flood Support pages, Calderdale Council and local Police pages and feeds. To see all of the messages use the mouse on the right handside of the panel to move the list.

How Do I Report a Hazard?

In this section:

Reporting a hazard

You can help us make this website as useful as possible for other users by marking hazards or problems on our map using our Report a Hazard facility (see "Crowdsourcing" above). Your pin will remain on the map for 24 hours.

You should also consider using our optional reporting feature to report the issue to the Council so action can be taken.

You can report most hazards to the Council by clicking next after you have selected the location and then completing the conatct details requested.  

You can choose hazards from four categories:

  • Flooding - with the option to also report to the Council to inform them of the problem.
  • Snow and Ice - this will only be shown as a hazard on the Eye on Calderdale map, there is no option to report to the Council.
  • Blocked Gullies (storm or highway drains underneath the road, pavement or walkways) - with the option to also report to the Council to inform them of the problem.
  • Other - See Below.

Selecting "Other" allows you to choose from a further 9 categories (all except Any Other Issues gives you the option to also report the issue to the Council) :

  • Damage to a bridge or wall
  • Abandoned Vehicle
  • Dangerous Building
  • Road Defect - Pot Hole
  • Road Defect - Markings damaged or worn
  • Road Defect - Other
  • Pavement Defect - Flag or Kerb trip hazard
  • Pavement Defect - Other
  • Any other Issues (Do not use this option if you want action taken for something (such as flytipping etc.) as this does not have an option to report the matter to the Council. It is intended for warning other users only.)

If your property is flooding and you need assistance, please DO NOT USE this form, phone the emergency services on 999 (or 101 if not an emergency) and/or contact the Council on 01422 288001 (or 01422 288000 out of normal business hours) instead to request assistance.

Only use the Report a Hazard form to warn others that the street has flooded.


Placing a pin in the map 

Use the map slider and mouse (or type in a postcode or address into the Location Search box) to locate the area you wish to report then click once on the map location to place your pin where the problem is. A pin will appear when you click in the comments box. If the pin is not in the right location it can be dragged until it is and it will update the report accordingly.

The name of the street or road will then appear in the Road Name box.

Certain reports will also show the Adoption Status of the street or road. 

An adopted road or street is one that is maintained at public expense, usually by the Council.

Unadopted roads and streets are privately owned and the maintenance of them is the responsibility of the owner.  This may be the residents of a road who each own the part in front of their house, or a third party, usually a landlord or developer.

While Eye on Calderdale records all reports on its map, the Council cannot accept any requests for work to be carried out on unadopted roads.

In the Comments box please give us as much information about the problem as possible however, please note that any comments you add will be publicly visible on this site. DO NOT INCLUDE any personal data or contact details about yourself at this point.

You can click on the Browse button to upload a picture of the situation being reported. Photos can be uploaded in PNG, JPG or GIF format using a single filename (i.e. has no gaps or breaks).

Clicking NEXT will place the pin of the incident on the Eye on Calderdale map. 

Where appropriate, clicking Next will then take you to a confidential reporting page to allow you the option of also sending this report to Calderdale Council. 

Please complete all parts of the form - the information provided is not stored on Eye on Calderdale and is sent directly to Customer First at Calderdale Council.

How Do I Warn my Neighbour?

Not everyone is a computer user or regularly visits websites.

You may know neighbours, friends or family that may be at risk of imminent flooding but wouldn't necessarily know. This is your opportunity to be a good neighbour and warn them.

The Warn your Neighbour page was set up to allow you to email the current flood warning alerts and warnings as well as attachments such as useful contacts list or a leaflet on what to do before, during and after a flood to someone who may be at risk.

It is always advisable to follow up any emails with a telephone call to ensure they received the warning.

There is also the ability to print off the warnings and manually post through the doors of your friends and neighbours if they live close to you.

Be a good neighbour and warn others of the risk of flooding.

How Do I Check if I'm at Risk of Flooding?

To check if you're at risk of flooding, type in your address or postcode in the check your flood risk location box and press enter. You can get a more accurate location by by zooming in on the map and manually moving the pin to the exact position of your property. 

The blue areas on the map represent the different levels of flood risk. You can change the opacity of these areas by using the slider on the "Check my Location" panel.

Please remember, this ONLY checks your risk of flooding from rivers - even if you get a "not at risk" message, your property or business may still be at risk of localised or flash flooding.
