Drainage and SUDsSuDS are a natural approach to managing drainage in and around properties and other developments. Sustainable drainage measures are ones which avoid adding to flood risks both at a development site and elsewhere in the catchment by replicating natural drainage processes. SuDS work by slowing and holding back the water that runs off from a site, alleviating flooding and allowing natural processes to break down pollutants.
Landscape and Nature
Industrial and Commercial Sheds
Introduction
The landscape-led approach advocated in this Code applies equally to the development of commercial and industrial buildings. This is particularly important for large scale commercial sheds. Their size, form, parking, servicing and lighting requirements make them difficult to assimilate into any environment.
LNIP 1
Commercial and industrial site layouts
Applicants must demonstrate that all developments for commercial and industrial buildings adopt a landscape-led approach in accordance with best practice set out within this chapter.
Landscape helps to break up and relieve the mass of dense industrial form found in areas such as Trafford Park as well as adding colour and improving biodiversity. In areas such as New Carrington, some new sheds will sit in open landscape, be visible from much greater distances, and often sit close to residential properties and new areas of open space. Consequently, developments in these areas will require more landscape to help assimilate the buildings into their setting.
Generally, the larger the building, the greater the site area that will be required to create an appropriate landscape setting. Landscape will help create a sense of placeA sense of place is the unique collection of qualities and characteristics that makes one town or development different to another. It lends meaning or attachment to a development or place, transforming it into a home, a neighbourhood, or a community. A sense of place is also what makes our physical surroundings worth caring about., screen or soften the form and appearance of large buildings, help with light spill from floodlighting, and provide a more pleasant environment for employees, visitors and passers-by. An inadequate landscape setting all too often results in large scale buildings dominating their sites, resulting in an unwelcoming and hostile environment. In all cases it is critical that landscape is an integral part of any development scheme. It must not be seen as an afterthought to green up the edges of a site.
Within commercial and industrial car parks, trees and hedges must be included as part of the Site Wide Landscape Strategy to break up large expanses of hard surfaced vehicle parking areas. No more than ten spaces should be provided in a row without being broken up by landscape.
As illustrated in the ‘Planting within large car park’ scenario below, no more than ten spaces should be provided in a double row without being broken up by landscape.
Applicants should demonstrate in their submission how this element of the Code has been complied with.

Best Practice guidance for commercial and industrial landscape
As part of the landscape-led approach to the Design Code it is considered important to deliver well-designed and robust landscape in association with industrial and commercial units.
The drawings below illustrate best practice in relation to landscaping provision for industrial and commercial sheds. The drawings illustrate a number of different scenarios and the relationship to adjacent land uses to provide, dependent on context:
- Effective screening or filtering of the built formForm is the three-dimensional shape and modelling of buildings and the spaces they define. Buildings and spaces can take many forms, depending upon their: size and shape in plan; height; bulk – their volume; massing – how bulk is shaped into a form; building lines – the alignment of building frontages along a street; and relationship to the plot boundary – and whether they share party walls or not. In the case of spaces, their form is influenced by the buildings around them.
- StreetscapeStreetscape is a term used to describe the natural and built fabric of the street, and defined as the design quality of the street and its visual effect, particularly how the paved area is laid out and treated. It includes buildings, the street surface, and also the fixtures and fittings that facilitate its use – from bus shelters and signage to planting schemes. planting to elevate the characterCharacter includes all of the elements that go to make a place, how it looks and feels, its geography and landscape, its noises and smells, activity, people and businesses. This character should be understood as a starting point for all development. Character can be understood at three levels; the area type in which the site sits, its surroundings and the features of the site. of a place
- Safeguarding of amenityThe desirable or useful features of a building or place which support its ongoing use and enjoyment by building occupants, residents, visitors, workers etc. It is usually understood to mean visual and aural amenity. Factors relevant to amenity include the general characteristics of the locality (including the presence of any feature of historic, architectural, cultural or similar interest), daylight, sunlight, outlook, privacy, air quality, effects of wind, odour, noise and vibration. Amenity should be preserved, so potential impacts need to be assessed and managed.
- Biodiversity enhancement through the provision and linkage of green and blue networks
- Sustainable DrainageSuDS are a natural approach to managing drainage in and around properties and other developments. Sustainable drainage measures are ones which avoid adding to flood risks both at a development site and elsewhere in the catchment by replicating natural drainage processes. SuDS work by slowing and holding back the water that runs off from a site, alleviating flooding and allowing natural processes to break down pollutants. solutions within each site.
Each site will have differing requirements, but all will be required to provide the necessary planting solutions to achieve the stated goal to suit the contextThe context includes the immediate surroundings of the site, the neighbourhood in which it sits and the wider setting. The context may include the physical surroundings of topography, movement patterns and infrastructure, built form and uses. An understanding of the context, history and character of an area must influence the siting and design of new development. and specific situation of each site.
The best practice illustrated in the plans, sections and tables below cover five different landscape scenarios. Trafford Design Code Landscape and Nature
scenario 1
Urban / built up - building elevation to highway (small to medium unit elevation
All developments in an urban or built-up area must be set back sufficiently from a highway / public facing boundary to allow sufficient space for planting beds and mature tree canopy spreads to be accommodated, and their associated management and maintenance. Hedgerows will be expected along the boundary. Planted swales as part of a SuDsSuDS are a natural approach to managing drainage in and around properties and other developments.

**If the planting bed is on a slope of steeper than 1:2, a section of the planting bed along with any retaining walls will need to be submitted to ensure that planting canbe successfully achieved.
*** Only required on the highway side, if management cannot be undertaken from the highway side of the boundary – may need to be larger if machinery is needed for maintenance.
Scenario 1 planting considerations
Hedges
Hedgerow planting will be required along boundaries between the unit and the highway.
All hedges will be expected to be maintained at an ultimate height of 1.8m-2m.
All hedge stock must be planted at 75% of the ultimate height. i.e. for a hedge with an ultimate height of 2m, the hedge plants should be planted at 1.5m tall.
Tree Species Considerations
- Deciduous or Evergreen
- Dense Crown to Trees
- Positive Species for Ecology
- Appropriate eventual Crown Spread/Form for the space available.
- Larger Species will be sought. Larger ultimate tree = Larger spacingbetween trees and to building will be required
scenario 2
Urban / rural - meaningful buffer planting to more sensitive land uses (all sizes)
All developments in an urban or rural setting where a meaningful planted screen is required between the building/site and a more sensitive land use, will be expected to demonstrate that sufficient space has been provided to allow for dense tree belt/copse planting beds, and their associated management and maintenance.

Applies to | Any elevation requiring screening from more sensitive land use or views |
Design goal | Effective screening |
Minimum solution | Woodland belt / large copse planting with or without earth bunding/building excavation to reduce visual impact |
Location of trees by species / type | All larger species trees should be planted within the central third of the planting bed, with woodland edge species towards the outer edges of the planting bed. This is to form a robust and effective layered buffer. |
Special considerations | In rural or more open areas, enhanced height or depth of screening, might be required to ensure screening from identified key viewpoints (which may be from elevated ground or long-distance views). In all areas, achieving relative height of screening can include a combination of tree planting and earth bunding/retaining walls/ground excavation to lower a building. Bunding maximum gradient is 1:2. |

scenario 3
Frontage / car parking between building and boundary (all sizes)
Where a principal frontage or car parking area faces a highway, sufficient space for planting beds and eventual tree canopy spreads need to be accommodated. The essential role of the planting is to create a setting for the building and to soften the effect of a bland/hard car park or frontage area. Hedgerows will be expected along the boundary. Trees should also form part of a planting scheme within the parking area itself.
