1 SUMMARY
Canal amp River Trust has produced this report to inform future investment priorities for
Hillingdon canal towpaths
The report was produced at the request of members of the Hillingdon Canals Partnership
and serves as a reference document for its work to promote and improve the boroughrsquos
waterways
It contains information for Hillingdon canal towpaths surveyed in 2013 covering
the Grand Union Canal (divided into 35 sections)
the Paddington Arm (1 section)
and Slough Arm (1 section)
For each section the general towpath condition levels of use and its function in connecting
people and places are considered
The result is a prioritised overview of borough towpaths for improvement which will support
funding applications and decisions

2 BACKGROUND
21 Better Towpaths for Everyone
Sir Brian Fender chair of London
Waterways Partnership launched
Better Towpaths for Everyone in
spring 2014
The report was endorsed by the
Mayorrsquos Cycling Commissioner
Andrew Gilligan and sets out
proposals for 3 strategic cross-
borough Quietways along the Grand
Union Canal Paddington Arm and
River Lee responding to the Mayorrsquos
Cycling Vision
Hillingdon sits across 2 of these Quietways

22 Hillingdon Waterspace Strategy
Canal amp River Trust works with key stakeholders brought together under the Hillingdon
Canals Partnership
The partnership is chaired by David Brough (of Hayes Town Partnership) and includes
representatives from Hillingdon Council Hayes Town Partnership GlaxoSmithKline Inland
Waterways Association Groundwork Thames 21 West Drayton Town Centre Action
Group and John McDonnell MP (Hayes amp Harlington)
In 2008 British Waterways produced a draft scoping report for a Hillingdon Waterspace
Strategy Good progress has been made on some initiatives identified in the Strategy and
this report will assist decisions on further work
An update of the Waterspace Strategy is planned during 201415 subject to funding

Hillingdon towpaths are diverse in character condition and levels of use They connect the
town centres of Hayes West Drayton Uxbridge and Rickmansworth as well as bordering
the major employment site at Stockley Business Park
24 Improvements so far
In addition to the Canal amp River Trustrsquos programme of maintenance and improvement
works securing partner funding has been vital to delivering better access signs and
surfacing Towpaths have been improved in recent years with funding from Hillingdon
Council and Transport for London Other sections are now in more need of improvement
Some areas that have benefitted from investment such as to the west of and including
Hillingdon Towpaths
Page 8 of 56
Hayes Town Centre are areas where we have long term aspirations for further improvement
given their strategic importance and high footfall
Hillingdon towpaths will also receive new Legible London signage during summer 2014

25 Opportunities
There are some canal locations in Hillingdon that are not well used by local residents and
visitors or have large areas of redundant space often underneath road or rail bridges
Whilst these structures can create dark and sometimes intimidating spaces these locations
also present opportunities for improvement and increase in use
Hillingdon in partnership with Canal amp River Trust has submitted a funding application to
Transport for Londonrsquos Incubator Fund This includes installing the Sharkrsquos Canoe Club
underneath the Hayes By-pass and using the area under North Hyde Gardens as a
volunteer base and community space to promote activity and use of the canal We are in
discussions with the adjacent landowner about landscaping an upper towpath and installing
a Trim Trail (outdoor fitness trail) in the area
Hayes By-Pass (Section 1) and North Hyde Gardens (Section 2)
The by-pass is a large flyover with an access ramp from the A312 to the towpath There is a
large amount of redundant space underneath the road bridge As the bridge blocks out
light the space is dark and uninviting but could be used to install a climbing wall or outdoor
gym equipment
North Hyde Gardens has a vacant space at the base of the bridge on the towpath This
space has attracted antisocial behaviour in the past and has since been secured by the
local police and the landowners Legal and General
Shackles Dock Western View and Hayes Town Centre
These locations central to the town centre have suffered from littering and street-drinking
however Thames 21 and Sharkrsquos Canoe Club are in discussions with the landowners of
Shackles Dock about accessing the site for canoeing and there is also a wild flower
landscaping scheme proposed for Hayes Town Centre

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)

5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows

1 SUMMARY
Canal amp River Trust has produced this report to inform future investment priorities for
Hillingdon canal towpaths
The report was produced at the request of members of the Hillingdon Canals Partnership
and serves as a reference document for its work to promote and improve the boroughrsquos
waterways
It contains information for Hillingdon canal towpaths surveyed in 2013 covering
the Grand Union Canal (divided into 35 sections)
the Paddington Arm (1 section)
and Slough Arm (1 section)
For each section the general towpath condition levels of use and its function in connecting
people and places are considered
The result is a prioritised overview of borough towpaths for improvement which will support
funding applications and decisions

2 BACKGROUND
21 Better Towpaths for Everyone
Sir Brian Fender chair of London
Waterways Partnership launched
Better Towpaths for Everyone in
spring 2014
The report was endorsed by the
Mayorrsquos Cycling Commissioner
Andrew Gilligan and sets out
proposals for 3 strategic cross-
borough Quietways along the Grand
Union Canal Paddington Arm and
River Lee responding to the Mayorrsquos
Cycling Vision
Hillingdon sits across 2 of these Quietways

22 Hillingdon Waterspace Strategy
Canal amp River Trust works with key stakeholders brought together under the Hillingdon
Canals Partnership
The partnership is chaired by David Brough (of Hayes Town Partnership) and includes
representatives from Hillingdon Council Hayes Town Partnership GlaxoSmithKline Inland
Waterways Association Groundwork Thames 21 West Drayton Town Centre Action
Group and John McDonnell MP (Hayes amp Harlington)
In 2008 British Waterways produced a draft scoping report for a Hillingdon Waterspace
Strategy Good progress has been made on some initiatives identified in the Strategy and
this report will assist decisions on further work
An update of the Waterspace Strategy is planned during 201415 subject to funding

Hillingdon towpaths are diverse in character condition and levels of use They connect the
town centres of Hayes West Drayton Uxbridge and Rickmansworth as well as bordering
the major employment site at Stockley Business Park
24 Improvements so far
In addition to the Canal amp River Trustrsquos programme of maintenance and improvement
works securing partner funding has been vital to delivering better access signs and
surfacing Towpaths have been improved in recent years with funding from Hillingdon
Council and Transport for London Other sections are now in more need of improvement
Some areas that have benefitted from investment such as to the west of and including
Hillingdon Towpaths
Page 8 of 56
Hayes Town Centre are areas where we have long term aspirations for further improvement
given their strategic importance and high footfall
Hillingdon towpaths will also receive new Legible London signage during summer 2014

25 Opportunities
There are some canal locations in Hillingdon that are not well used by local residents and
visitors or have large areas of redundant space often underneath road or rail bridges
Whilst these structures can create dark and sometimes intimidating spaces these locations
also present opportunities for improvement and increase in use
Hillingdon in partnership with Canal amp River Trust has submitted a funding application to
Transport for Londonrsquos Incubator Fund This includes installing the Sharkrsquos Canoe Club
underneath the Hayes By-pass and using the area under North Hyde Gardens as a
volunteer base and community space to promote activity and use of the canal We are in
discussions with the adjacent landowner about landscaping an upper towpath and installing
a Trim Trail (outdoor fitness trail) in the area
Hayes By-Pass (Section 1) and North Hyde Gardens (Section 2)
The by-pass is a large flyover with an access ramp from the A312 to the towpath There is a
large amount of redundant space underneath the road bridge As the bridge blocks out
light the space is dark and uninviting but could be used to install a climbing wall or outdoor
gym equipment
North Hyde Gardens has a vacant space at the base of the bridge on the towpath This
space has attracted antisocial behaviour in the past and has since been secured by the
local police and the landowners Legal and General
Shackles Dock Western View and Hayes Town Centre
These locations central to the town centre have suffered from littering and street-drinking
however Thames 21 and Sharkrsquos Canoe Club are in discussions with the landowners of
Shackles Dock about accessing the site for canoeing and there is also a wild flower
landscaping scheme proposed for Hayes Town Centre

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)

5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows
Hillingdon Towpaths

1 SUMMARY
Canal amp River Trust has produced this report to inform future investment priorities for
Hillingdon canal towpaths
The report was produced at the request of members of the Hillingdon Canals Partnership
and serves as a reference document for its work to promote and improve the boroughrsquos
waterways
It contains information for Hillingdon canal towpaths surveyed in 2013 covering
the Grand Union Canal (divided into 35 sections)
the Paddington Arm (1 section)
and Slough Arm (1 section)
For each section the general towpath condition levels of use and its function in connecting
people and places are considered
The result is a prioritised overview of borough towpaths for improvement which will support
funding applications and decisions

2 BACKGROUND
21 Better Towpaths for Everyone
Sir Brian Fender chair of London
Waterways Partnership launched
Better Towpaths for Everyone in
spring 2014
The report was endorsed by the
Mayorrsquos Cycling Commissioner
Andrew Gilligan and sets out
proposals for 3 strategic cross-
borough Quietways along the Grand
Union Canal Paddington Arm and
River Lee responding to the Mayorrsquos
Cycling Vision
Hillingdon sits across 2 of these Quietways

22 Hillingdon Waterspace Strategy
Canal amp River Trust works with key stakeholders brought together under the Hillingdon
Canals Partnership
The partnership is chaired by David Brough (of Hayes Town Partnership) and includes
representatives from Hillingdon Council Hayes Town Partnership GlaxoSmithKline Inland
Waterways Association Groundwork Thames 21 West Drayton Town Centre Action
Group and John McDonnell MP (Hayes amp Harlington)
In 2008 British Waterways produced a draft scoping report for a Hillingdon Waterspace
Strategy Good progress has been made on some initiatives identified in the Strategy and
this report will assist decisions on further work
An update of the Waterspace Strategy is planned during 201415 subject to funding

Hillingdon towpaths are diverse in character condition and levels of use They connect the
town centres of Hayes West Drayton Uxbridge and Rickmansworth as well as bordering
the major employment site at Stockley Business Park
24 Improvements so far
In addition to the Canal amp River Trustrsquos programme of maintenance and improvement
works securing partner funding has been vital to delivering better access signs and
surfacing Towpaths have been improved in recent years with funding from Hillingdon
Council and Transport for London Other sections are now in more need of improvement
Some areas that have benefitted from investment such as to the west of and including
Hillingdon Towpaths
Page 8 of 56
Hayes Town Centre are areas where we have long term aspirations for further improvement
given their strategic importance and high footfall
Hillingdon towpaths will also receive new Legible London signage during summer 2014

25 Opportunities
There are some canal locations in Hillingdon that are not well used by local residents and
visitors or have large areas of redundant space often underneath road or rail bridges
Whilst these structures can create dark and sometimes intimidating spaces these locations
also present opportunities for improvement and increase in use
Hillingdon in partnership with Canal amp River Trust has submitted a funding application to
Transport for Londonrsquos Incubator Fund This includes installing the Sharkrsquos Canoe Club
underneath the Hayes By-pass and using the area under North Hyde Gardens as a
volunteer base and community space to promote activity and use of the canal We are in
discussions with the adjacent landowner about landscaping an upper towpath and installing
a Trim Trail (outdoor fitness trail) in the area
Hayes By-Pass (Section 1) and North Hyde Gardens (Section 2)
The by-pass is a large flyover with an access ramp from the A312 to the towpath There is a
large amount of redundant space underneath the road bridge As the bridge blocks out
light the space is dark and uninviting but could be used to install a climbing wall or outdoor
gym equipment
North Hyde Gardens has a vacant space at the base of the bridge on the towpath This
space has attracted antisocial behaviour in the past and has since been secured by the
local police and the landowners Legal and General
Shackles Dock Western View and Hayes Town Centre
These locations central to the town centre have suffered from littering and street-drinking
however Thames 21 and Sharkrsquos Canoe Club are in discussions with the landowners of
Shackles Dock about accessing the site for canoeing and there is also a wild flower
landscaping scheme proposed for Hayes Town Centre

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)

5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows
Hillingdon Towpaths

1 SUMMARY
Canal amp River Trust has produced this report to inform future investment priorities for
Hillingdon canal towpaths
The report was produced at the request of members of the Hillingdon Canals Partnership
and serves as a reference document for its work to promote and improve the boroughrsquos
waterways
It contains information for Hillingdon canal towpaths surveyed in 2013 covering
the Grand Union Canal (divided into 35 sections)
the Paddington Arm (1 section)
and Slough Arm (1 section)
For each section the general towpath condition levels of use and its function in connecting
people and places are considered
The result is a prioritised overview of borough towpaths for improvement which will support
funding applications and decisions

2 BACKGROUND
21 Better Towpaths for Everyone
Sir Brian Fender chair of London
Waterways Partnership launched
Better Towpaths for Everyone in
spring 2014
The report was endorsed by the
Mayorrsquos Cycling Commissioner
Andrew Gilligan and sets out
proposals for 3 strategic cross-
borough Quietways along the Grand
Union Canal Paddington Arm and
River Lee responding to the Mayorrsquos
Cycling Vision
Hillingdon sits across 2 of these Quietways

22 Hillingdon Waterspace Strategy
Canal amp River Trust works with key stakeholders brought together under the Hillingdon
Canals Partnership
The partnership is chaired by David Brough (of Hayes Town Partnership) and includes
representatives from Hillingdon Council Hayes Town Partnership GlaxoSmithKline Inland
Waterways Association Groundwork Thames 21 West Drayton Town Centre Action
Group and John McDonnell MP (Hayes amp Harlington)
In 2008 British Waterways produced a draft scoping report for a Hillingdon Waterspace
Strategy Good progress has been made on some initiatives identified in the Strategy and
this report will assist decisions on further work
An update of the Waterspace Strategy is planned during 201415 subject to funding

Hillingdon towpaths are diverse in character condition and levels of use They connect the
town centres of Hayes West Drayton Uxbridge and Rickmansworth as well as bordering
the major employment site at Stockley Business Park
24 Improvements so far
In addition to the Canal amp River Trustrsquos programme of maintenance and improvement
works securing partner funding has been vital to delivering better access signs and
surfacing Towpaths have been improved in recent years with funding from Hillingdon
Council and Transport for London Other sections are now in more need of improvement
Some areas that have benefitted from investment such as to the west of and including
Hillingdon Towpaths
Page 8 of 56
Hayes Town Centre are areas where we have long term aspirations for further improvement
given their strategic importance and high footfall
Hillingdon towpaths will also receive new Legible London signage during summer 2014

25 Opportunities
There are some canal locations in Hillingdon that are not well used by local residents and
visitors or have large areas of redundant space often underneath road or rail bridges
Whilst these structures can create dark and sometimes intimidating spaces these locations
also present opportunities for improvement and increase in use
Hillingdon in partnership with Canal amp River Trust has submitted a funding application to
Transport for Londonrsquos Incubator Fund This includes installing the Sharkrsquos Canoe Club
underneath the Hayes By-pass and using the area under North Hyde Gardens as a
volunteer base and community space to promote activity and use of the canal We are in
discussions with the adjacent landowner about landscaping an upper towpath and installing
a Trim Trail (outdoor fitness trail) in the area
Hayes By-Pass (Section 1) and North Hyde Gardens (Section 2)
The by-pass is a large flyover with an access ramp from the A312 to the towpath There is a
large amount of redundant space underneath the road bridge As the bridge blocks out
light the space is dark and uninviting but could be used to install a climbing wall or outdoor
gym equipment
North Hyde Gardens has a vacant space at the base of the bridge on the towpath This
space has attracted antisocial behaviour in the past and has since been secured by the
local police and the landowners Legal and General
Shackles Dock Western View and Hayes Town Centre
These locations central to the town centre have suffered from littering and street-drinking
however Thames 21 and Sharkrsquos Canoe Club are in discussions with the landowners of
Shackles Dock about accessing the site for canoeing and there is also a wild flower
landscaping scheme proposed for Hayes Town Centre

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)

5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows
Hillingdon Towpaths

2 BACKGROUND
21 Better Towpaths for Everyone
Sir Brian Fender chair of London
Waterways Partnership launched
Better Towpaths for Everyone in
spring 2014
The report was endorsed by the
Mayorrsquos Cycling Commissioner
Andrew Gilligan and sets out
proposals for 3 strategic cross-
borough Quietways along the Grand
Union Canal Paddington Arm and
River Lee responding to the Mayorrsquos
Cycling Vision
Hillingdon sits across 2 of these Quietways

22 Hillingdon Waterspace Strategy
Canal amp River Trust works with key stakeholders brought together under the Hillingdon
Canals Partnership
The partnership is chaired by David Brough (of Hayes Town Partnership) and includes
representatives from Hillingdon Council Hayes Town Partnership GlaxoSmithKline Inland
Waterways Association Groundwork Thames 21 West Drayton Town Centre Action
Group and John McDonnell MP (Hayes amp Harlington)
In 2008 British Waterways produced a draft scoping report for a Hillingdon Waterspace
Strategy Good progress has been made on some initiatives identified in the Strategy and
this report will assist decisions on further work
An update of the Waterspace Strategy is planned during 201415 subject to funding

Hillingdon towpaths are diverse in character condition and levels of use They connect the
town centres of Hayes West Drayton Uxbridge and Rickmansworth as well as bordering
the major employment site at Stockley Business Park
24 Improvements so far
In addition to the Canal amp River Trustrsquos programme of maintenance and improvement
works securing partner funding has been vital to delivering better access signs and
surfacing Towpaths have been improved in recent years with funding from Hillingdon
Council and Transport for London Other sections are now in more need of improvement
Some areas that have benefitted from investment such as to the west of and including
Hillingdon Towpaths
Page 8 of 56
Hayes Town Centre are areas where we have long term aspirations for further improvement
given their strategic importance and high footfall
Hillingdon towpaths will also receive new Legible London signage during summer 2014

25 Opportunities
There are some canal locations in Hillingdon that are not well used by local residents and
visitors or have large areas of redundant space often underneath road or rail bridges
Whilst these structures can create dark and sometimes intimidating spaces these locations
also present opportunities for improvement and increase in use
Hillingdon in partnership with Canal amp River Trust has submitted a funding application to
Transport for Londonrsquos Incubator Fund This includes installing the Sharkrsquos Canoe Club
underneath the Hayes By-pass and using the area under North Hyde Gardens as a
volunteer base and community space to promote activity and use of the canal We are in
discussions with the adjacent landowner about landscaping an upper towpath and installing
a Trim Trail (outdoor fitness trail) in the area
Hayes By-Pass (Section 1) and North Hyde Gardens (Section 2)
The by-pass is a large flyover with an access ramp from the A312 to the towpath There is a
large amount of redundant space underneath the road bridge As the bridge blocks out
light the space is dark and uninviting but could be used to install a climbing wall or outdoor
gym equipment
North Hyde Gardens has a vacant space at the base of the bridge on the towpath This
space has attracted antisocial behaviour in the past and has since been secured by the
local police and the landowners Legal and General
Shackles Dock Western View and Hayes Town Centre
These locations central to the town centre have suffered from littering and street-drinking
however Thames 21 and Sharkrsquos Canoe Club are in discussions with the landowners of
Shackles Dock about accessing the site for canoeing and there is also a wild flower
landscaping scheme proposed for Hayes Town Centre

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)
Hillingdon Towpaths

5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows
Hillingdon Towpaths

22 Hillingdon Waterspace Strategy
Canal amp River Trust works with key stakeholders brought together under the Hillingdon
Canals Partnership
The partnership is chaired by David Brough (of Hayes Town Partnership) and includes
representatives from Hillingdon Council Hayes Town Partnership GlaxoSmithKline Inland
Waterways Association Groundwork Thames 21 West Drayton Town Centre Action
Group and John McDonnell MP (Hayes amp Harlington)
In 2008 British Waterways produced a draft scoping report for a Hillingdon Waterspace
Strategy Good progress has been made on some initiatives identified in the Strategy and
this report will assist decisions on further work
An update of the Waterspace Strategy is planned during 201415 subject to funding

the major employment site at Stockley Business Park
24 Improvements so far
In addition to the Canal amp River Trustrsquos programme of maintenance and improvement
works securing partner funding has been vital to delivering better access signs and
surfacing Towpaths have been improved in recent years with funding from Hillingdon
Council and Transport for London Other sections are now in more need of improvement
Some areas that have benefitted from investment such as to the west of and including
Hillingdon Towpaths
Page 8 of 56
Hayes Town Centre are areas where we have long term aspirations for further improvement
given their strategic importance and high footfall
Hillingdon towpaths will also receive new Legible London signage during summer 2014

25 Opportunities
There are some canal locations in Hillingdon that are not well used by local residents and
visitors or have large areas of redundant space often underneath road or rail bridges
Whilst these structures can create dark and sometimes intimidating spaces these locations
also present opportunities for improvement and increase in use
Hillingdon in partnership with Canal amp River Trust has submitted a funding application to
Transport for Londonrsquos Incubator Fund This includes installing the Sharkrsquos Canoe Club
underneath the Hayes By-pass and using the area under North Hyde Gardens as a
volunteer base and community space to promote activity and use of the canal We are in
discussions with the adjacent landowner about landscaping an upper towpath and installing
a Trim Trail (outdoor fitness trail) in the area
Hayes By-Pass (Section 1) and North Hyde Gardens (Section 2)
The by-pass is a large flyover with an access ramp from the A312 to the towpath There is a
large amount of redundant space underneath the road bridge As the bridge blocks out
light the space is dark and uninviting but could be used to install a climbing wall or outdoor
gym equipment
North Hyde Gardens has a vacant space at the base of the bridge on the towpath This
space has attracted antisocial behaviour in the past and has since been secured by the
local police and the landowners Legal and General
Shackles Dock Western View and Hayes Town Centre
These locations central to the town centre have suffered from littering and street-drinking
however Thames 21 and Sharkrsquos Canoe Club are in discussions with the landowners of
Shackles Dock about accessing the site for canoeing and there is also a wild flower
landscaping scheme proposed for Hayes Town Centre

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)
Hillingdon Towpaths
Page 12 of 56
5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows
Hillingdon Towpaths

the major employment site at Stockley Business Park
24 Improvements so far
In addition to the Canal amp River Trustrsquos programme of maintenance and improvement
works securing partner funding has been vital to delivering better access signs and
surfacing Towpaths have been improved in recent years with funding from Hillingdon
Council and Transport for London Other sections are now in more need of improvement
Some areas that have benefitted from investment such as to the west of and including
Hillingdon Towpaths
Page 8 of 56
Hayes Town Centre are areas where we have long term aspirations for further improvement
given their strategic importance and high footfall
Hillingdon towpaths will also receive new Legible London signage during summer 2014

25 Opportunities
There are some canal locations in Hillingdon that are not well used by local residents and
visitors or have large areas of redundant space often underneath road or rail bridges
Whilst these structures can create dark and sometimes intimidating spaces these locations
also present opportunities for improvement and increase in use
Hillingdon in partnership with Canal amp River Trust has submitted a funding application to
Transport for Londonrsquos Incubator Fund This includes installing the Sharkrsquos Canoe Club
underneath the Hayes By-pass and using the area under North Hyde Gardens as a
volunteer base and community space to promote activity and use of the canal We are in
discussions with the adjacent landowner about landscaping an upper towpath and installing
a Trim Trail (outdoor fitness trail) in the area
Hayes By-Pass (Section 1) and North Hyde Gardens (Section 2)
The by-pass is a large flyover with an access ramp from the A312 to the towpath There is a
large amount of redundant space underneath the road bridge As the bridge blocks out
light the space is dark and uninviting but could be used to install a climbing wall or outdoor
gym equipment
North Hyde Gardens has a vacant space at the base of the bridge on the towpath This
space has attracted antisocial behaviour in the past and has since been secured by the
local police and the landowners Legal and General
Shackles Dock Western View and Hayes Town Centre
These locations central to the town centre have suffered from littering and street-drinking
however Thames 21 and Sharkrsquos Canoe Club are in discussions with the landowners of
Shackles Dock about accessing the site for canoeing and there is also a wild flower
landscaping scheme proposed for Hayes Town Centre

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)

5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows

25 Opportunities
There are some canal locations in Hillingdon that are not well used by local residents and
visitors or have large areas of redundant space often underneath road or rail bridges
Whilst these structures can create dark and sometimes intimidating spaces these locations
also present opportunities for improvement and increase in use
Hillingdon in partnership with Canal amp River Trust has submitted a funding application to
Transport for Londonrsquos Incubator Fund This includes installing the Sharkrsquos Canoe Club
underneath the Hayes By-pass and using the area under North Hyde Gardens as a
volunteer base and community space to promote activity and use of the canal We are in
discussions with the adjacent landowner about landscaping an upper towpath and installing
a Trim Trail (outdoor fitness trail) in the area
Hayes By-Pass (Section 1) and North Hyde Gardens (Section 2)
The by-pass is a large flyover with an access ramp from the A312 to the towpath There is a
large amount of redundant space underneath the road bridge As the bridge blocks out
light the space is dark and uninviting but could be used to install a climbing wall or outdoor
gym equipment
North Hyde Gardens has a vacant space at the base of the bridge on the towpath This
space has attracted antisocial behaviour in the past and has since been secured by the
local police and the landowners Legal and General
Shackles Dock Western View and Hayes Town Centre
These locations central to the town centre have suffered from littering and street-drinking
however Thames 21 and Sharkrsquos Canoe Club are in discussions with the landowners of
Shackles Dock about accessing the site for canoeing and there is also a wild flower
landscaping scheme proposed for Hayes Town Centre

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)

5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows

25 Opportunities
There are some canal locations in Hillingdon that are not well used by local residents and
visitors or have large areas of redundant space often underneath road or rail bridges
Whilst these structures can create dark and sometimes intimidating spaces these locations
also present opportunities for improvement and increase in use
Hillingdon in partnership with Canal amp River Trust has submitted a funding application to
Transport for Londonrsquos Incubator Fund This includes installing the Sharkrsquos Canoe Club
underneath the Hayes By-pass and using the area under North Hyde Gardens as a
volunteer base and community space to promote activity and use of the canal We are in
discussions with the adjacent landowner about landscaping an upper towpath and installing
a Trim Trail (outdoor fitness trail) in the area
Hayes By-Pass (Section 1) and North Hyde Gardens (Section 2)
The by-pass is a large flyover with an access ramp from the A312 to the towpath There is a
large amount of redundant space underneath the road bridge As the bridge blocks out
light the space is dark and uninviting but could be used to install a climbing wall or outdoor
gym equipment
North Hyde Gardens has a vacant space at the base of the bridge on the towpath This
space has attracted antisocial behaviour in the past and has since been secured by the
local police and the landowners Legal and General
Shackles Dock Western View and Hayes Town Centre
These locations central to the town centre have suffered from littering and street-drinking
however Thames 21 and Sharkrsquos Canoe Club are in discussions with the landowners of
Shackles Dock about accessing the site for canoeing and there is also a wild flower
landscaping scheme proposed for Hayes Town Centre

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there
18 metres
surfaced width
Vegetation hedges
managed not to
encroach
Tarmac with edging boards
and tar spry and chip finish

Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)

5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows

3 TOWPATH SPECIFICATION
The photograph below shows a typical towpath in the borough which has been recently
improved It shows the preferred towpath specification and was taken in July 2013 on the
Grand Union Canal Paddington Arm
We aim to achieve these minimum specifications
18m wide surfaced path tarmac with tar spray and chip finish with timber edging
boards
Verges maintained either side of the path with a minimum of 600mm on the
waterside and 500mm at the back where possible
Vegetation managed not to encroach and limit space for sharing the towpath but
still providing a habitat for nature and space for moored boats
The surface finish gives an audible crunch which lets others know yoursquore there

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)
Hillingdon Towpaths
Page 12 of 56
5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows
Hillingdon Towpaths

4 COST ASSUMPTIONS
The Trust uses its Towpath Estimator Tool to generate costs (see Appendix 1)
Estimated construction costs in this report are based on the Trustrsquos national term
contract rates for the 201314 financial year and are subject to inflationary uplift
Costs exclude design contingency and other project related costs such as legal or
land
The individual surveyed section reports (see Appendix 3) also include estimates for
additional measures to enhance the canal such as improvements to access points
bridges or signage
The total cost for towpath and additional improvements is estimated at just under
pound5million with pound13million in the high priority category (see Section 7 for complete
breakdown)
Hillingdon Towpaths
Page 12 of 56
5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows
Hillingdon Towpaths

5 METHOD
The boroughrsquos canal towpaths were considered as 37 discrete sections
The 35 sections of the Grand Union Canal have been surveyed and presented in
order from the Bulls Bridge canal junction (between Southall and Hayes) as far as
Rickmansworth divided where bridges cross the towpath or at locks
The Paddington Arm was not surveyed in detail for this report It has had recent
enhancement works however a small section of towpath requires resurfacing This
has been earmarked for improvement as part of the Southall Gasworks
Development
The Slough Arm is subject to wider discussions with other local authorities and is
considered high priority

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows
Hillingdon Towpaths

6 ASSESSMENT CRITERIA
61 Design Guidance amp Standards
Towpaths are multi-functional spaces shared by
everyone whether for boating angling walking or
cycling They provide an attractive traffic-free
experience particularly appealing to enjoyment of
leisure time and can attract new and novice cyclists
The Trust has its own Towpath Design Guide which
sets out the approach needed for waterways
Following national consultation on sharing Towpaths
in early 2014 the Trust will publish a new Towpath
Policy setting out its expectations and approach to
managing and improving towpaths for shared use
Elsewhere new London Cycling Design Standards
(LCDS) were released for consultation in June 2014
The LCDS includes a Cycling Level of Service (CLoS)
which enables assessment of the suitability of a route
for cycling The design standards provide guidance to
ensure cycle routes are delivered to the following
good design outcomes
1 Safe
2 Direct
3 Comfortable
4 Coherent
5 Attractive
6 Adaptable
The LCDS refers to shared space although mainly
between motorised vehicles cyclists and pedestrians
The design standards do not adequately analyse the
needs of pedestrians and cyclists in off-highway
environments such as parks and canal towpaths
Similarly the National Cycle Network - Guidance and
Practical Details document produced by Sustrans
doesnrsquot fully consider constraints limitations and
character of towpaths The minimum width of 2m is
not always achievable for example under bridges
However 18m is often sufficient width for towpaths in
areas with medium to low flows
