ECOLOGICAL MITIGATION AND ENHANCEMENT STRATEGY

The Ecological Mitigation and Enhancement Strategy is presented in greater detail within the Landscape and Ecological Mitigation Plan (LEMP) prepared for the Dorset Innovation Park (refer to Appendix 1).

This strategy is controlled by the Biodiversity Mitigation Plan that has been agreed with the Local Authority. It identifies the existing areas with known landscape and ecological value, based upon ecology survey work carried out. It also sets out the measures required for different parts of Dorset Innovation Park for enhancement in line with the masterplan concept as part of a holistic site-wide strategy. This includes strategies for dealing with the translocation of sensitive acid grasslands.

POTENTIAL DEVELOPMENT PLOT PHASING AND AVAILABILITY

The concept masterplan for the Dorset Innovation Park has been designed to be as flexible as possible. However, it is clear that enabling work will be necessary to ensure that each development plot is made ready in order to accommodate new development.

Such enabling work will include clearance of existing structures and the translocation of sensitive acid grassland depending on each plot.

The mitigation and enhancement strategy for this covered by the LEMP falls predominantly within the Parkland element of the LDO, outside of individual development parcels. This would be delivered by the Council as an initial ‘enabling works’ phase to remove the majority of the constraints from development plots. Given the dynamic nature

of ecological features, the LEMP also sets out a management strategy to ensure that new ecology issues do not establish in the intervening period between the enabling works and construction of individual development plots.

The phasing sequence identified here is indicative of the Council’s initial strategy, but will depend on a number of factors, including potential tenant interest in different plots as well as the optimal site-wide strategy for the translocation of acid grasses, which will be determined by the Council as part of a more detailed implementation strategy.

LIGHTING STRATEGY (FOR BATS)

As described within the LEMP and BMP (refer to Appendix 1) a baseline survey was undertaken on 14th February 2018 between 6.30pm and 12.30pm to identify and comment on the existing lighting profile across the site. The centre of the site is generally well lit with column luminaires providing illuminance to most roadways throughout the site. The majority of the southern boundary of the site, specifically Willow Road to the existing Weatherford Labs, has an illuminance of 0 lux with 4no. security lamps solely providing illuminance to buildings.

The western area of the site has low light levels, mostly < 0.5 lux, with the exception of Monterey Avenue which has an average illuminance of 20.3 lux. An unnamed road runs along the northern boundary of the site which has an average illuminance of 16.9 lux. These luminaires are, however, facing towards the centre of the site with dense foliage greatly reducing the light spill thrown backwards.

Care should be taken when lighting the northern, eastern and southern edges of the site as various species of light sensitive bats have been recorded in these areas. The light levels in these areas are very low, mostly < 0.5 lux, and any new development should seek to not increase these levels further.

Light levels will be reduced east of the pond to create a dark corridor between the pond and the stream for foraging bats.

Every effort must be made to maintain the existing dark corridor along the southern edge of the site which provides a foraging route for rare bat species. See plot specific guidance for further information.

The following design guidance should be adhered to when designing the external lighting strategy for the development:

• ILP & Bat Conservation Trust: Guidance Note 08/18 - Bats and artificial lighting in the UK Bats and the Built Environment series

• ILP Guidance Notes for the Reduction of Obtrusive Light GN01:2011;

• CIBSE Lighting Guide 6 (LG6) – Outdoor Environment;

• CIBSE SLL Code for Lighting 2012;

• BS 5489-1:2013 – Code of Practice for Design of Road Lighting;

• CEN/TR 13201-1: Road Lighting – Part 1: Selection of Lighting Classes;

• CIE – Guidelines for minimising Sky Glow;

• Bat Conservation Trust: Artificial Lighting and Wildlife Interim Guide 2014;

• Royal Commission on Environmental Pollution – Artificial Light in the Environment.

• The new ILP Guide for Bats and artificial lighting (08/18) and the Guidance Notes for the Reduction of Obtrusive Lights are the primary documents referred to by local authorities and planning departments to categorise the provision of external lighting. External lighting should be compliant to Dark Sky requirements and to Lighting Environmental Zone CIE E2.

Recommendations for Future External Lighting Proposals

• The use of directional, LED lamps is recommended to both save energy and ensure that light is only directed to the required areas.

• The use of timeclocks and photocells are recommended as a minimum to control the times that the external lighting is switched on. Passive Infrared Sensors (PIRs) can also be used, mainly on building perimeters, to only switch external lighting on when activated.

• To protect bat sensitive areas, the best strategy is to avoid lighting the area at all, only using artificial illuminance if deemed necessary. However, the use of cowls can be introduced in bat sensitive areas to ensure that light is not directed into areas where it is not needed. Bat sensitive areas should not be lit above 0.5 lux.

• To allow bats to cross the site to forage for food, bat corridors of 0.5 lux can be accommodated into the street lighting strategy.

• A range of lamp colour temperatures were found on site, from < 2,700 K to 4,000 K. It is recommended that any new fittings use a similar colour temperature to create continuity throughout the site. A warm white such as 3,000 K is recommended to create a warm, welcoming environment and reduce the emission of white and blue wavelengths of the light spectrum.

• The above measures are incorporated into the Design Guide for the site.

PLACEMAKING STRATEGY

In order to establish a sense of place at the Innovation Park, a series of urban design principles have been established here to ensure that each development plot and character area contributes towards an interesting environment for the Innovation Park’s inhabitants.

These placemaking principles are seen as minimum guidance for ensuring that there is sufficient variety in building forms and distinctive features in key locations, driven in large part by the Concept Masterplan Summary diagram on page 23 of this Design Guide.

The primary focus of this placemaking strategy is to ensure that the Heathland Park at the heart of the Innovation Park is reinforced with strong and engaging building frontages around its edges, which will help to strengthen the relationship between development plots and the communal spaces and facilities at the core of the Innovation Park, such as the Nucleus, the Pavilion and the Heathland Park.

DESIGN GUIDANCELANDSCAPE AND ARCHITECTURAL ELEMENTS

PART 3


39


DESIGN GUIDANCE:LANDSCAPE ELEMENTS

This Design Guide is intended to provide additional design specific guidance related to the implementation of the Local Development Order proposals for the Dorset Innovation Park.

While the existing roads and service routes will be retained where possible, they form an established rigid grid and orthogonal layout. The intention is for the landscape to weave naturally between the plots, rather than form a traditional and formal ‘Business Park’ design. The landscape character will be defined by specific features to each area and any new landscape elements will continue a natural and informal landscape character across the site.

The Concept Masterplan sets out a number of areas around the Dorset Innovation Park formed of open spaces and routes framed by buildings and building plots. This section of the Design Guide deals with matters related to the landscape setting, communal open spaces, roads, routes and boundaries while the Design Guide for buildings is dealt with in the subsequent architecture guidance section.

The details contained within this section of the Design Guide provide clear guidance on the nature and character of the different routes and spaces that make up the overall proposals for development around the Dorset Innovation Park.

The Guide will be used to inform the relationship between individual development plots and the surrounding roads, character areas and spaces to inform future detailed designs.

Therefore, the landscape character parameters identified in this section are important to ensure that the landscape and ecological assets are safeguarded for the future and that the communal spaces will deliver the Concept Masterplan intent. It will ensure that paths and roads are usable in terms of vehicle, pedestrian and cycle movement as well as the safeguarding of areas for spill out activities. Any proposed deviation from these parameters will have to be agreed with and approved by the Local Authority landscape officer when preparing formal proposals.

The following landscape and urban design principles are requirements to be taken into account in preparing detailed designs for all areas of the LDO area:

1. All work to be carried out in accordance with the Parameter Plans as set out in this Design Guide. Any deviations from the plan that may be required in order to accommodate design briefs for development plots not anticipated at the time of the creation of the Concept Masterplan shall be carried out in such a way as to maintain the integrity of the plan as a whole.

2. The Council exercising its development management function, will provide guidance and direction and detailed design guidance and will scrutinise and sign off all subsequent stages of project design development, which will comply with guidance contained within this Design Guide.

3. The Design Guide shall be read and interpreted as a whole and then in terms of specific plot/ area guidance.

4. The landscape design of planting and surfaces are to form part of an integrated plan for the entire LDO area. Paving materials are to be hardwearing and durable as set out in this Design Guide.

5. Careful consideration is to be given to the procurement and placing of public art as part of the public space design.

The landscape character for the Park is what defines the site as a whole. Given the number of landscape and ecological assets that exist, the character will reflect the local natural landscape, incorporating the acid grassland areas, existing native trees and tree groups and will pick up the Dorset Heathland features.

CHARACTER AREA:THE GATEWAY

• As the entrance to the Dorset Innovation Park, the Gateway Area will introduce the landscape character of the site and will set the scene by forming part of the receptor sites for the translocation of on site acid grassland (as identified on the LEMP Ecological Mitigation and Enhancement Strategy plan). The acid grassland areas to be retained or translocated will take precedent over other landscape character types, such as Dorset Heathland, which will be focused around the gatehouse entrance feature area and for on-plot planting schemes.

• There will be a new gatehouse building to define the entrance of the Park, with reconfigured parking and an integrated bus stop area to provide public transport links with the wider area. There is an opportunity to include workplace bikes and an electric car pool at the entrance to the Park to encourage the use of sustainable transport modes within and around the site.

• The Park will remain a secure site with controlled access and egress via the gatehouse and operator. The existing secure boundary fence will be retained and refurbished where necessary. New areas of fence required are to include a minimum 1.8m high weldmesh fence - refer to the Land Use Areas and Secure Boundary diagram for further details.

KEY CHARACTERISTICS AND FEATURES

• The shared footpath and cycleway will be retained and enhanced along the southern boundary with an uplift to the planting to bring it into character. This will include native structure planting to the boundary fence line to obscure the boundary fencing and to screen views from the adjacent public footpath that runs along the southern edge.

• The existing footpath along the southern edge of Monterey Avenue is to be removed and replaced with translocated acid grassland.

• Existing trees and vegetation are to be assessed for suitability with non-native trees and ornamental shrubs to be removed.

• An attractive entrance feature to incorporate the Dorset Innovation Park logo/signage could be included as part of the landscape in a creative and unique way. This could be formed of natural rocks or timber stacks with plant species to reference the surrounding Heathland landscape character and to introduce the new identity and branding for the Dorset Innovation Park.

• Existing sculptures are to be retained as part of the site wide artwork strategy and their locations may be changed as part of this.

• The existing low importance grassland along Monterey Avenue will form part of the site wide translocation strategy for acid grassland as outlined in the LEMP. This can be implemented from hay collected from on-site grassland communities.

• Proposed native structure planting along southern boundary line to create a visual screen from adjacent footpath to include: hawthorn, blackthorn, elder, hazel, field maple and guelder rose. Refer to schedule on page 51.

• For all the character areas only true native cultivars should be used as part of new planting proposals.

• Existing non-native trees and shrubs and poor quality specimens are to be removed - refer to Tree survey by Soundwood Tree Consultancy for species details.

• There are some existing formal raised shrub beds at the river culvert that could be retained and replanted with Dorset Heathland character area planting as described for the Gate House area above.

• Materials: footpath and cycleway - self-binding buff gravel 10mm to dust. Cycle and pedestrian path separated from road edge along southern boundary (existing route) minimum of 2.4m wide. New weldmesh fence 1.8m high to LDO boundary.

• Road - Resurfaced tarmac with existing kerb stones to be replaced where required. Road to form part of Main Spine Circulation Route. Refer to page 52.

• The majority of grassland will be close mown to promote rare acid grassland species but a strip alongside existing trees and scrub will be left unmown to provide habitat for reptiles.

CHARACTER AREA:PARKLAND

• The landscape for the central parkland area will be a simple treatment of native trees and acid grassland, incorporating many of the existing trees and tree groups, with thinning and removal of non-native or undesireable species as part of the site wide management strategy. This area will provide receptor sites as part of the translocated grassland strategy set out in the LEMP document and summarised on page 31 of this document.

• The areas around the central plots will provide a balance between retaining the existing or translocated acid grassland, which can be managed and mown regularly to be a part of the amenity space, and forming new habitats of the Dorset Heathland for the areas within the Nucleus and Pavillion plots themselves.

• The existing pond area is to be extended and enhanced by removing some trees and by regrading the banks in select areas to include native marginal planting. This area would


be enhanced for wildlife and managed to encourage the marginal vegetation to develop (i.e. not publicly accessible to all banks).

• All routes are to be pedestrian priority within the Parkland area. This includes footpaths, cycleways and mown grass paths that create routes through the site for pedestrians and cyclists. This is intended to be the preferred route for pedestrians and cyclists to move around the site. Separating pedestrians and cyclists from the vehicular routes acts as a safety measure and improves the pedestrian and cycle experience.

• The landscape includes a circular route for recreational use, which can also form the basis of a trim trail for more sportive and active use. Some outdoor gym features and activities can be incorporated along this route.

• Strategically placed seating and picnic benches will be included in this area as destinations for lunchtime and breaks.

• Bird boxes will be installed on suitable trees to provide nesting opportunities for the many birds which are resident within the site.

• Planting: Refer to the LEMP grassland translocation strategy (P31) Dorset Heathland planting mix for on-plot areas (page 47) and marginal planting around pond (page 48).

• Existing grassland areas of low ecological interest to be replaced with translocated grasslands of High or Moderate Interest as shown on phasing plan (page 32 & 33) and further described within the LEMP.

• Pond area to be extended and redesigned to include habitat creation to banks with managed access, designed seating and viewing areas. Existing trees are to be thinned out and non-natives to be removed in select locations.

• Materials: Shared footpaths and cycle routes are to be a minimum of 2.4m wide self-binding gravel with timber edges, a buff coloured resin bound gravel or a buff coloured base and binder course (such as NatraTex Cotswold or similar) surface where they cross roads.

• Furniture: timber benches, picnic tables, litter bins and bollards included at road crossings. Design to be appropriate to rural setting.

• Memorial trees: there are some existing memorial trees around the pond area - these are to be identified and protected/ retaiend as part fo the site proposals.

CHARACTER AREA:SOUTHERN EDGE

• This area is identified as a receptor site for some acid grassland to be translocated from several proposed development plots, as indicated on the LEMP’s Ecological Mitigation and Enhancement Strategy Plan and summarised on page 31 of this document.

• Any existing buffer planting to the site boundary is to be retained and gaps to be infilled with native species to provide some visual screening of the boundary fence to the adjacent footpath and views of the site from this and the Dorset AONB. Any sections of new fence are to be 3m high to tie in with the adjacent existing fencing and to reflect the LEMP impact avoidance strategy on the adjacent sensitive sites to the south.


• This location requires a sensitive lighting design where the presence of light-intolerant bats has been recorded to the south. This is defined further in the lighting strategy on p34.

• There are some valuable grasses already in this area and a specific management regime of regular cutting of road verges and no pesticide spraying will need to be adhered to in order to maintain the important grassland community.

• Groups or clumps or lines of large stature native trees are to be included to boundary locations.

• Agricultural reference to the farmland mosaic character area with the use of in-situ poured concrete paths and defined boundaries of native hedgerows.

• Bat boxes will be installed on suitable trees to provide roosting opportunities for bats which forage along the wooded edges of the site.

BUILDING FORM

Each building should make a positive response to its setting including public spaces and adjacent buildings. Every new building will become part of the context for later work and should not impose constraints on later designers’ ability to comply with this design guide. The following requirements are fundamental:

Enclosure: A primary goal is the creation of a coherent set of connected spaces. Each building contributes to this sense of enclosure – main facades must be on the plot boundary at back of pavement clearly defining an attractive transition between public and private space.

Active ground floor uses: Ground floors should be designed to allow for a variety of active uses to evolve as the area matures and to maximise the opportunity to provide vibrant and visually attractive ground level frontages to all public spaces and circulation routes. Shared spaces within buildings where people gather should generally be located at ground level, facing principal public spaces.

Robust fabric: All buildings should have generous column spacing and floor-to-floor heights to maximise adaptability. Structural frames should be designed for long life and extendibility.

Shallow plan (where appropriate to the proposed use of the building): To maximise daylight and reduce reliance on artificial lighting and ventilation all workstations and office desks should be within 7.5 metres of windows on the building perimeter or facing a well-lit atrium (unless appropriately designed skylights are installed).

Hierarchy of Circulation: Main building entrances should be located to relate coherently to the public spaces and circulation routes defined in the master plan, while delivery entrances, plant rooms and service intakes should face away from the principal public spaces and pedestrian circulation routes. Where this is not possible for specific operational reasons, delivery entrances, plant rooms and service intakes must be appropriately screened or treated to ensure they address and respond to the surrounding character areas.

Sustainable design: All new development across the Dorset Innovation Park are expected to adopt high performing sustainable design principles. The use of renewable energy is encouraged where appropriate to reduce the environmental impact of new developments, responding to both the construction of the development and the proposed uses within. Additional information on this can be found in the Energy Statement submitted as part of the LDO.

ARCHITECTURAL CHARACTER

The masterplan team has identified the following characteristics for the Dorset Innovation Park:

1. Contemporary metal and composite rainscreen cladding with clean, modern detailing.

2. Areas of large glazing to provide transparency to encourage flow between buildings and landscaping and visual connection for public engagement.

3. Innovative lighting internally and externally.

Composition. Large, unarticulated masses are discouraged to better blend into the wider landscape. Each building elevation should be conceived as single harmonious composition that responds to the internal organisation of the building, the public space that it fronts and the form and character of neighbouring buildings. The pattern of windows and other elements, the proportions of openings and the relationship of details to the whole are vital elements of the design. Entrances should be proportioned to relate to the overall design of façade and public space.

Materials. One of the defining characteristics should be the limited palette materials that suggest high-tech science parks, including rainscreen cladding and other high quality materials where their colour, texture and weathering characteristics are similar to well-tried materials. The use of reclaimed materials is encouraged.

Architectural Detail. The design of architectural detail is an important element of the overall composition - it should be functional (not least in helping to protect finishes from the weather), promote legibility, reflect hierarchy and contribute to expression of scale and proportion. The primary frontage should be the focus of architectural display with secondary buildings given a simpler treatment.

Signage and Lighting. Lettering on buildings can make a significant contribution to local character and should be designed to suit the proportions of the building. It should not clutter the façade or destroy or obscure architectural detailing. The following types of signage are preferred: painted lettering on the building surface, relief lettering, planted or incised lettering and etched or painted windows. Lighting should be unobtrusive and in line with the overarching lighting strategy for the Innovation Park. Wherever possible street lighting should be attached to buildings rather than on independent lighting columns.

Roofscape. The treatment of roofscape generally is important given the sensitivity of the Area of Outstanding Natural Beauty to the south. Roof loads are lower than floor loads, which allows lighter structures to be used on the topmost floor where unlimited top light is available. Pitched roofs offer the potential for interesting spaces and optimum siting for PV panels (whether installed at the outset or retro-fitted). Rooftop plant can be bulky and intrusive: wherever possible it should be accommodated at basement level or enclosed in building elements that are integrated into the overall architectural composition.

This section of the Design Guide relates to the design of buildings and landscape within each development plot. The vision of the Dorset Innovation Park is of a ‘robust, progressive architecture’ with modern and elegant buildings that integrate with the surrounding landscaping.

Building Form

The form of the building should be innovative suggesting progression.

Glazing and Lighting

A balance of human-scale fenestration and large areas of curtain walling to indicate public/private spaces, bring in natural light and frame views and activities. Principal entrances and inviting areas should have increased transparency.

Integrated lighting design to carry through internally and externally in various scales.
