Creating a Shed Green Roof

At our semi-detached house in Halifax, we have built a lean-to shed for our bikes and bins, to free up some space in the garage. So far, so very mundane… but – this shed has been getting lots of attention/compliments – it has a great-looking green roof! It helps to ‘slow the flow’, encourages bees and butterflies, makes us smile, and – IT WASN’T HARD TO DO!

We have previously had our house in Mytholmroyd flooded, and I am part of Slow The Flow: Calderdale’s management team. So, although our current house does not flood, we understand that it is those upstream, rather than those who flood, that need to take action.  This inspired us to include included a green roof and water butts in the shed’s design.

I wanted to note down in a blog post how we’ve done it with the hope that it will inspire others to follow suit – if lots of us do something similar, it could have a big impact on Calderdale’s surface water flooding problems!

My husband, Dan, built a bespoke structure, with a sturdy timber frame to support the additional weight of a green roof. The size of the top of the shed is about 4m x 1m.

To begin with, he lined it with traditional roofing felt – we didn’t know how long it would take us to get around to putting the green roof on. We have left that felt on as an extra layer of waterproofing.

There is a shallow fall on the roof, and it drains to a plastic gutter, which feeds two connected water butts before overflowing to the drain that already existed in the drive. Interestingly, both water butts filled straight away, in our first heavy rain event (perhaps because the planting hadn’t had time to establish yet).  In future, we will leave the tap open ahead of heavy rainfall in future, so that they can act as ‘mini leaky dams’ (i.e. the water comes in a bigger hole than it is allowed out through, thereby slowing the flow).  We have also installed a solar powered irrigation system, that uses water from the water butts (http://irrigatia.com) – a nice optional extra! (We would recommend it, but it does need some tlc – in the dry summer we’ve been having, it has struggled and clogged when the water butt has been empty).

We bought a pond liner (which was actually big enough to use folded over for extra protection, though this is probably unnecessary), laid it, and built a timber upstand, about 10cm deep, around the top of the roof to both hold it in place (with heavy duty staples) and contain the green roof layers. The pond liner laps up on three sides, and down under the timber on one side, to feed the gutter along the bottom edge. We left a drainage gap between timbers on this bottom edge, but water should also naturally seep through at the join.

As a drainage layer, we used some angular gravel (single layer) we had left over from another DIY project and then some lightweight ‘Sportag’ – again a single layer. This drainage layer is about 2-3cm in total. Shed green roofs don’t necessarily need it, if you don’t have the depth/structural strength for the extra weight you could just use soil. It just gives extra water storage capacity, and should prevent the soil getting boggy in wet weather.

The topsoil (multipurpose peat free compost) layer finishes it off – 4 125L bags plus an extra 25L (total 525L) spread thinly after the seed mix, provided a depth of about 5cm.

Again, you could use a thinner layer of soil, but this depth, with the drainage layer underneath, allows us to use the roof to grow small ‘garden’ plants in rather than just sedum – you can see in the pictures that we have used a combination of potted plants for immediate effect, and a seed mix. Plants are chosen that should cope with both dry conditions (much of the time on a green roof!) and occasional water inundation.

We used a mix of seeds – some we had lying around, including a sample of ‘Pictorial Meadows’ pastel mix, and some purpose bought – we’ll look forward to seeing what does well! A ‘Pictorial Meadows’ tip about mixing seeds with sand, was an excellent way to sow the seed. It allows a more even distribution, and an easy visual clue as to where the seed has been scattered!

Plant list:

Pots

  • Saxifraga x arendsii ‘Marto White’ (Saxifrage)
  • Saxifraga x arendsii ‘Alpino Early White’ (Saxifrage)
  • Sedum acre ‘Aurea’
  • Thymus x2 – exact species unknown, one gold variegated, one purple (Thyme)
  • Anemone blanda ‘Blue Shades’
  • Pritzelago alpina ‘Ice cube’ (Chamois cress)
  • Viola x2 – exact species unknown, one blue/purple, one pink/purple

Seeds

  • Pictorial Meadows ‘Pretty as a Picture’ pastel mix
  • Nigella damascena ‘Persian Jewels’ (love-in-a-mist)
  • Linaria maroccana ‘Fairy Bouquet’ (toadflax)
  • Scabiosa atropurpurea ‘Blue Cushion’ (scabius)
  • Mysotis sylvatica ‘indigo’ (Forget-me-not)
  • Helictotrichon sempervirens (blue oat grass)
  • Allium schoenoprasum (chives)
  • Wilko ‘mixed white flowers for wildlife’

Once the shed was built, the green roof installation took two of us a few hours’ work. The shed in total, including green roof/water butt elements cost a total of around £650 (£50 on plants/seeds) Hard to separate the roof construction from the shed as a whole – it was a big shed, and sturdy construction deliberately to support the roof.

Hebden Bridge Town Hall Rain Garden Planter Celebrations – a great party!

A huge thank you to everyone who has been involved in designing, building, funding, or coming along to the launch event for, the rain garden planters at Hebden Bridge Town Hall. It has been a fantastic team effort, and we had a great day for the launch event on Friday June 29th – with, ironically, not a drop of rain!

 

Councillor Carol Stow, the Mayor of Hebden Royd Town Council, officially ‘opened’ the planters (with her ceremonial watering can), and we thank the talented young people from Calder Valley Youth Theatre and Hebden Bridge Junior Band, for providing us with an afternoon of excellent entertainment.

 

The planters will remain in the courtyard at the Town Hall for the foreseeable future, and we will be monitoring them carefully, using our bespoke system to (hopefully) bring you some scientific findings about just how much they help to slow the flow of storm water. In a rainfall event, water from the downpipes is taken through the soil/plants, before making its way more slowly back into the drainage system.

 

In heavy rainfall/flood events, many urban SuDS interventions can help to reduce flood levels. In particular, these types of systems can help to reduce the impact of overflow from Calderdale’s combined surface & foul sewers. This reduces the risk of contaminated flood water entering our homes and rivers.

 

This project was developed and built in collaboration with a fantastic team, including the Calder Rivers TrustHebden Bridge Community AssociationGreen Future Building2B Landscape Consultancy Ltd, Calder Valley Clean UpThe Basement Project – and kindly funded by the Postcode Local Trust.

 

It now features on our shiny new ‘case studies’ page: http://slowtheflow.net/urban-suds-case-study-hebden-bridge-town-hall-courtyard-rain-garden-planters/ Do have an explore of them all, and if you have a project that you would like to share with us as a case study, please visit http://slowtheflow.net/case-study-submissions/

 

It is easy to feel complacent in this beautiful summer of hot, dry weather – but heavy rainfall now could easily result in surface water flooding, as hard, dry ground sheds water more easily to the drains.

Urban SuDS Case Study: Hebden Bridge Town Hall – Courtyard Rain Garden Planters

Calder Rivers Trust & Slow The Flow Calderdale

Rain Garden Planters

Slowing the flow of rainwater into the drainage system, thus reducing the potential for combined sewer flooding

The Town Hall Courtyard planters project is a collaborative community
venture, funded by a grant from the Postcode Local Trust.

It is part of a wider initiative to help us
all understand how urban Sustainable Drainage Systems (SuDS) can play a
part in flood alleviation.

The completed storm-water planters

Five large storm-water planters were installed in the courtyard of Hebden Bridge Town Hall in June 2018. Planters are 80cm high, 75cm deep and range from 90cm to 2.4m wide. They are made from tricoya, a sustainable and extremely durable engineered wood panel.

Ornamental and edible plants were chosen to withstand flood and drought conditions and to improve the riverside bio-diversity corridor.

adding the plants

Raised planters are good if space is tight, or ground conditions don’t allow water to soak away. They divert water from drainpipes, to slow / reduce the flow into sewers. They can be built over existing surfaces as long as there is a plan for any overfow. Excess water can continue into the existing system, as before.

With this being in a public space, it is ideal for promoting SuDS, particularly encouraging people to make their own interventions at home

Assembling the planters

Plants
Resilient plants have been chosen to cope with either flood or drought, and promote riverside  biodiversity – also some that the café can use in their delicious food!
Species list available here.

Monitoring
As part of wider research, the effectiveness of the planters at slowing down rainwater will be monitored by measuring the inflow and outflow of rainwater using the measuring gauges in one of the planters.

River Health
Rain gardens and other SuDS features filter the water and reduce the sediment that enters the river from runoff. By reducing peak flow into sewers they can also reduce the amount of serious pollution from Combined Sewer Overflows (CSOs), improving the quality of water in your local river.

Riverside Biodiversity Corridors
Linking landscaped spaces together along the riverside and including a variety of nectar rich species to attract insects and birds helps to create a wildlife corridor along the riverside.

Rain Garden Planter Construction
These planters are made from “extreme” Tricoya (#MTX) which has all the design flexibility of MDF, but is more durable and sustainable – perfect for external, wet and natural environments.
They were manufactured on a not-for-profit basis by local riverside social enterprise, Green Future Building and installed by volunteers.

The project has been funded by a £20,000 grant from People’s Postcode Lottery with collaborative design and implementation from the following:

Urban SuDS Case Study: Swale on Tipside by Todmorden Riverside Improvement Group (TRIG)

The Swale in 2018

What? Constructed a small swale to take surplus water away from the path and make a damp area of grass wetter and more biodiverse.

Where? Tipside Todmorden.

When? December 2016.

Design:The swale has been designed to provide a new wetland plant community in an already wet grassy area, and to provide a small storage area for surplus rainwater. The swale is a shallow hollow no deeper than a foot, with gently sloping sides which covers an area about 60 m2. Drainage is poor in this area leading to frequent flooding of the nearby path, so it is intended that surplus rainwater will fill the swale rather than flood the path. 

Following heavy rain the swale will fill with water, this will then gradually drain away or evaporate, leaving the swale empty for the next downpour. The swale has been planted with a number of different wetland species to make the area more attractive both to people and other wildlife. A range of species will give a long flowering period from early species like Marsh Marigold in April, through to late summer species like meadowsweet and purple loosestrife.

Excavating the swale

Benefits/Constraints: We have been really pleased with the establishment of the plants in the swale, though we have to keep the area well managed to keep unwanted species like Himalayan balsam, nettles, docks and bindweed at bay. We haven’t fully resolved the flooding of the footpath yet and have more work to do with additional drains but we hope once this is completed the path will be much drier and less muddy.
Further opportunities: We are looking at another wet area on another part of the site where a marshland community might be established.

Who? TRIG designed, managed and fundraised the scheme, supervised the groundworks and did the planting

Funding: Plant material – native wild flower plug plants: £413 Compost etc to supplement very poor substrate £85 Ground works to excavate swale £ 910. Funds were provided thanks to the people’s postcode lottery.

Urban SuDS Case Study: Domestic Garden, Halifax

Green roof

What? Front garden: Hedge and planting. Drive: Shed Green Roof and water butts

Where? Family home (1950’s 3 bed semi-detached house), Halifax.

When? Early 2018 (Hedge February, Green Roof April)

Design: Replaced wall and hard surface at the front with a hornbeam hedge, and planted bulbs below. Built bespoke sturdy (to support extra weight of green roof) shed, over existing tarmac. 

The layers of the green roof are (bottom to top): standard shed felting // waterproof pond liner (doubled because we had enough) // about 2-3cm depth drainage layer (angular gravel + ‘Sportag’) // about 5cm depth peat free potting compost // plants / seeds. Any water that filters out of the soil is collected in water butts, via a downpipe.

Benefits/Constraints: The hedge prevents some of the rainfall ever reaching the ground, the roots soak up some of the water, and the soil absorbs and releases it slowly, instead of the wall and hard surface that would have shed water quickly straight into the drain. Similarly at the back, the green roof intercepts rainfall that would have shed straight into the gully – and we can water our other pots with the water butts. In addition, the view both of and from the house are greatly improved at front and back. We have noticed more wildlife, particularly birds, and as gardeners are glad of extra planting space.

Further Opportunities: We plan to install a permeable drive and large planting bed at the front as well.

Who? Husband and wife team! (He’s a bit of a handyman…) (and the baby cheer-led)

Funding: about £150 for the hedge, including soil. About £650 for the materials for the whole shed, including green roof and two water butts. We also added a solar powered irrigation system that uses the water butt water – about another £100.

Building / Implementation: Needed planning and materials ordering in advance.

Hedge: Required wall demolition, digging out a trench, filling with soil, planting.

Green Roof: needed the shed building first! Green roof elements needed hoisting up via ladders, securing down as appropriate, planting/seeding. Slightly careful detailing to drain to guttering. Water butts installed as instructions.

Before!

June 2018 – An update on “Slow the Flow Calderdale” Projects

Most people who live and work in the Calder Valley will now have heard of Slow The Flow Calderdale and the work we are doing to reduce the likelihood of flooding, especially if your house or business is at risk of being flooded.  Indeed, our reach and influence now permeates throughout the UK – we have connections with communities, academics and organisations involved in Natural Flood Management (NFM). 

Natural Flood Management will not prevent or reduce flooding on its own, but neither do we wish to rely solely on hard engineered schemes, which tend to push the problem downstream rather than addressing the cause.  There has to be a holistic approach to flood management using every method available from natural processes to the traditional engineered schemes we have seen throughout the UK.  NFM can be a cost effective way of reducing flood risk, and often provides additional Green Infrastructure benefits such as biodiversity, air quality, aesthetic value, and mental health. It is projects like ours which are helping to build an evidence base to demonstrate that natural methods can work effectively to reduce flood risk. 

Communities who are at risk of flooding cannot rely on central government and their agencies to tackle this ever increasing and expensive issue and as such we must all play our own small part.  Our projects demonstrate how small interventions can be adopted on a local level by householders and landowners and not just by local authorities and government agencies. 

Since 2016, Slow The Flow Calderdale has been developing various projects to contribute to the reduction of flood risk in the Calder Valley.  The lessons we are learning will benefit us all around the UK and beyond.  Here is an overview of them all. 

A Pilot Natural Flood Management Project in Hardcastle Crags, Hebden Bridge

This was our first project and came about as a result of the river surveys we conducted throughout the Calder Valley in 2016.  These surveys, using our growing number of extremely dedicated volunteers, enabled us to identify areas which could be used to slow the flow of rain water as it made its way off the hillsides into the river network. We walked miles of our rivers detailing the features of Hebden Water, Crimsworth Dean, and others from Todmorden through to Mytholmroyd.  These surveys were physically enduring at times but it gave us an intimate understanding of the river network which the agencies responsible for flood prevention had never had previously.  

The river surveys  gave us the knowledge and insight to prepare a report on the land at Hardcastle Crags owned by The National Trust who.  The report was accepted by the Environment Agency who subsequently funded the work we now carry out building NFM interventions such as leaky woody dams in Hardcastle Crags.  To date, we have built over 160 leaky woody Dams in Hardcastle Crags using our teams of dedicated volunteers and working with The National Trust as part of their forestry plan. The project also involves thinning of the woodland as part of the longer term woodland management plan.  This will encourage a stronger and healthier understorey of plants and young trees which increases the roughness and slows the flow and also reduces sediment erosion.  

We have also welcomed corporate groups from the Environment Agency and Calderdale Council and others as well as our regular and growing number of volunteers who work with us twice a month.  Throughout the Summer, we will also be working with Hebden Bridge Cubs to help them with their badges as they help us build even more leaky woody dams. Additionally more corporate groups are planned throughout the year.  

If your company would like to get involved, please email secretary@slowtheflow.net with your details.

Calderdale Natural Flood Management Grant Fund

Slow The Flow along with The Source Partnership and South Pennine Facilitation Fund, Calderdale Council and The Environment Agency have recently launched the NFM Grant Fund. 

Calderdale farmers and landowners now have a new opportunity to help deliver natural flood management and contribute to flood mitigation and alleviation.  As part of the Calderdale flood action plan currently being delivered, Calderdale Council has been working with the Environment Agency and The Source Partnership with support from the Woodland Trust on this new grant scheme.  Initially £200,000 is being released by the Environment Agency and Calderdale Council to support delivery of NFM interventions. Slow The Flow was instrumental in putting this new scheme together and we continue to work on its implementation with our partners agencies. 
 
The scheme launched on Wednesday 9 May and initial applications need to be with Calderdale Council by Wednesday 20 June. Grants will pay for the cost of the measures installed and cover some of the future maintenance costs.

If you are a landowner who owns land in the Calder Valley and you think you could contribute to NFM, more information can be found here – http://eyeoncalderdale.com/nfm-grant-scheme

River level monitoring in the Calder Valley

Along the Calder Valley, there are currently only 8 river level monitoring stations from Todmorden to Sowerby Bridge.  More info here on the current monitors in Calderdale.

Along with our partners The Flood Network and The Environment Agency, we are installing more river level monitors and engaging with local residents to develop this network of river level monitors. To date we have six monitors at Hebden Water and Crimsworth Dean Beck which measure the river levels and use LoRaWan technology to relay these results back to a central hub for communities to see how our rivers respond to heavy rainfall.

These new river level monitors will serve two purposes. Firstly, they allow the public to view the river state at times of heavy rainfall and secondly they will allow Slow The Flow to measure and demonstrate the efficacy of the natural flood management interventions that are proposed and currently being implemented in the Upper Calder Valley.

More here on this.

Slow the Flow Calderdale have also been awarded a grant from the Community Foundation for Calderdale to execute a youth project focusing around our river level monitoring activities. As a pilot to the project, Slow The Flow are holding a short course on river flooding and Natural Flood Management which will also cover river level monitoring techniques which we are proposing to roll out across the Upper Calder catchment.

You Can Slow The Flow! Encouraging urban Sustainable Drainage Systems (SuDS)

Everybody living or working in the Calder Valley can make small changes to slow the flow of stormwater in their own homes, at work, school or in public places. 

Many small interventions, to slow run-off, could result in a significant amount of water being temporarily stored during storm events in our urban areas.

This will help to reduce peak flows (see the storm hydrograph above) which, together with catchment management and traditional flood defences, would contribute to reducing the scale and damaging effects of flood events.

SuDS NFM principles Section Diagram

Sustainable Drainage Systems (SuDS) mimic the natural cycle of water management, by retaining water where it lands instead of shedding it quickly to drains and watercourses, which can lead to flooding. 

Lots of useful ideas and schemes can be found here either at home, work, school or in public places. 

As a result of global warming, it is clear that our climate is changing resulting in ever changing weather patterns from floods to drought.  It is also clear that the money required to pay for hard engineered schemes will continually be stretched so it is up to us as a community to originate and develop ideas to reduce the likelihood and impact of flooding events. 

Summary

Slow The Flow Calderdale have been incredibly busy since our formation in 2016, and our workload shows no sign of abating.  In fact, we are busier now than even on the various challenges we have set ourselves. We all remain unpaid in the management of Slow The Flow and rely continuously on the very hard work and dedication of our amazing group of volunteers who range in age from 10 to over 70.

We are very lucky to have the significant support of our partner agencies and thank them for the help and assistance they provide to the people of the Calder Valley in reducing flood risk.  Much of this work by them often goes unrewarded at times but if we continue to work together, we can all make a difference and reduce the likelihood of flooding throughout the UK.

If you can help in any of the schemes above, please do get in touch with us.

If you live in other parts of the UK and think that your community can benefit from NFM, then our website www.slowtheflow.net is a good place to start to develop your own schemes.

A short course for young people on local natural flood management – Week commencing 18th June

Volunteering in Hardcastle Cargs

18th May 2018

A SHORT COURSE FOR YOUNG PEOPLE ON LOCAL NATURAL FLOOD MANAGEMENT – Week commencing 18th June

Slow the Flow Calderdale have been awarded a grant from the Community Foundation for Calderdale to execute a youth project focusing around our river level monitoring activities. As a pilot to the project, Slow The Flow are holding a short course on river flooding and Natural Flood Management which will also cover river level monitoring techniques which we are proposing to roll out across the Upper Calder catchment.

The course is suitable for 15 to 19 year olds, those who are either currently studying or interested in studying Geography, Geology/Earth science, Environmental Science or Civil Engineering at degree level and for anyone else who is interested in this ever increasingly popular area of Natural Flood Management.

The short course will take place over three days starting on Monday 18 June. It will include some classroom work, a field trip along Colden Water followed by practical experience building leaky woody dams in Hardcastle Crags. A shorter briefing of the subject material may be arranged for Saturday 23 June for those unable to attend during the week.

The purpose of the field trip is to determine the best locations to install river level monitors and the students will be actively engaged in this process. Once the monitors are installed around the catchment, these will join those already available for viewing by the general public in real time over the internet, available here

There is a technical flavour to the proposed roll-out of the course with the opportunity to build river monitors use Raspberry Pi computers and “LoRaWAN” to transfer the data using the “Internet of Things”. This is intended to broaden the appeal of associated learning opportunities to those looking to study Electronics/Electrical Engineering, the Internet of Things or IT and how these subjects fit around the natural environment.

These river level monitors will serve two purposes. Firstly, they allow the public to view the river state at times of heavy rainfall and secondly they will allow Slow The Flow to measure and demonstrate the efficacy of the natural flood management interventions that are proposed and currently being implemented in the Upper Calder Valley.

Emma Woods-Bolger Assistant Director of the Community Foundation for Calderdale said:

“Big Lottery Fund and Department of Culture, Media & Sport are each investing £20 million seed funding over four years to create the #iwill fund. Locally the Community Foundation for Calderdale, are acting as match funders and are awarding grants on behalf of the #iwill fund.

The #iwill campaign aims to increase participation in youth social action by 50% by 2020. This includes activities such as campaigning, fundraising and volunteering, all of which create a double-benefit – to communities and young people themselves.

Stuart Bradshaw from Slow The Flow Calderdale said:

“Here is an opportunity for young people to learn more about causes of devastating floods and how to build resilience into their communities. We are really excited to be able to facilitate this course for young people in the Calder Valley and to see the next generation of scientists & engineers develop their skills in Natural Flood Management”

Cllr Barry Collins, Calderdale Council’s Cabinet Member for Regeneration and Economic Development, said:

“This is a great opportunity for young people to learn about this fast-growing area of flood risk management and the amazing work that Slow the Flow is doing in the Calder Valley.

The Calderdale Flood Action Plan recognises the many benefits of using natural flood management alongside other methods such as engineered flood defences and we are excited to see Slow the Flow pioneering the use of data to develop NFM knowledge and improve understanding of its impacts.”

If you are a student studying for A Levels or have a general interest in the Environment or design and technology or you work with students who are studying these subjects and would like to get involved, please email secretary@slowtheflow.net to reserve your place.

Places are completely free thanks to the grant from the Community Foundation for Calderdale but spaces are limited so applications will be received on a first come, first served basis.
