Active frontage

Making frontages ‘active’ adds interest, life and vitality to the public realm. This can mean:

frequent doors and windows

few blank walls; articulation of facades, with projections such as bays and porches incorporated, providing a welcoming feel, and on occasion, lively internal uses visible from the outside, or spilling onto the street.

Active Ground Floor Use

Active ground floor uses are generally considered uses that attract pedestrian activity and provide direct access to the general public, for example shops, restaurants, cafes, bars, travel agencies, banks are active uses. Residential uses and offices would not normally be considered as active uses for ground floors (but could contribute to the active frontage by having a front door to a residential or office use on upper floors).

Active Travel

Active Travel refers to modes of travel that involve a level of physical activity. The term is often used interchangeably with walking and cycling, or “walking and wheeling”, but active travel can also include trips made by wheelchair, mobility scooters, adapted cycles, e-cycles, scooters, cycle sharing schemes and horse riding.

Find out more about what Biodiversity Net Gain means for development proposals and planning applications

BREEAM assessment

Evaluates the procurement, design, construction, and operation of a development against a range of targets based on performance benchmarks. It focuses on sustainable value across a range of categories: Energy, Land use and ecology. "BREEAM" stands for "Building Research Establishment Environmental Assessment Methodology." BREEAM accreditation is administered by its parent company, Building Research Establishment (BRE). It is the oldest method of assessing, rating, and certifying a building's environmental sustainability.

Brownfield or PDL (previously developed land)

Land which has had a development on it before; often brownfield sites are ex-industrial, and later converted to housing.

Development Management

That part of the planning process that deals with planning applications.

Development Plan

Our Development Plan is made up of a series of documents that are the starting point for all local Planning decisions.

Health Impact Assessment (HIA)

A practical tool which is used to assess the potential health impacts of a policy, programme or project on a population. HIAs are used to maximise positive health effects and minimise and mitigate any possible negative health impacts. A HIA helps decision-makers in local authorities and other stakeholders make choices and actions to prevent ill health, promote good health and reduce health inequalities.

Heritage Action Zone (HAZ)

Learn more about regulations around HMOs

Housing and Economic Land Availability Assessment (HELAA)

The HELAA is a technical document that helps to identify a supply of potentially suitable sites for housing or economic use and is used to inform planning policies. It is not a decision-making document and the inclusion of sites in a HELAA should not be seen as an intention to allocate these sites for development, or that planning permission will be granted.

View the draft HELAA documents submitted as part of the Evidence Base for this consultation

Learn more about the HELAA process and the call for sites in B&NES

Housing Development Boundary (HDB)

The boundary which defines that part of certain settlements within which the principle of residential development will usually be acceptable subject to compliance with policies in the Development Plan and other material considerations.

I to M

Infrastructure

Facilities, services, and installations needed for the functioning of a community, such as transportation and communications systems, water and power lines, and public institutions including schools and hospitals.

Liveable Neighbourhoods

Residential areas in cities and towns are often used by through-traffic, which creates noise, pollution and hazards. By reducing the dominance of vehicles, Liveable Neighbourhoods reconsider how street space is reallocated, creating healthier outdoor spaces for everyone to share, as well as vibrant places where people want to dwell and spend money. Liveable Neighbourhoods reduce car dependency by transforming streets into safer, more attractive spaces where everyday needs can be met locally and where people travelling actively and by public transport are prioritised.

Learn more about our Liveable Neighbourhoods programme

Local Development Order (LDO)

Local Development Orders are made by local planning authorities and give a grant of planning permission to specific types of development within a defined area. They streamline the planning process by removing the need for developers to make a planning application to a local planning authority. They create certainty and save time and money for those involved in the planning process.

Local Housing Allowance (LHA)

Rates are used to calculate Housing Benefit for tenants renting from private landlords.

Local Nature Recovery Strategies (LNRS)

An England-wide system of spatial strategies that will establish priorities and map proposals for specific actions to drive nature’s recovery and provide wider environmental benefits.

Find out more about the WECA LNRS

Local Planning Authority (LPA)

As a local planning authority, we are the local government body that is empowered by law to exercise urban planning functions within the council’s boundary area

Main town centre uses

See NPPF definition linked here.

Micromobility

There is no fixed definition of micromobility, but it is generally used as a term to define types of vehicles that are small (or under a certain weight). For example, some commentators define micromobility as a vehicle under 500kg. Examples include bicycles and scooters. Most vehicles that fit into the micromobility definition are designed to carry a single person, however others, for example cargo cycles can carry multiple people or goods. It can include motor powered or assisted modes such as e-bikes or e-scooters, as well as self-propelled vehicles such as bicycles or skateboards.

Mitigation

Extra measures that may be necessary to lessen any harmful impacts of a development. These might include things which limit noise or light pollution, or compensate for environment loss.

Mobility Hub

Mobility hubs are spaces where public, shared and active travel modes are co-located alongside improvements to the public realm. They enable travellers to make smooth and safe transfers between different modes, swapping private cars for shared vehicles, bikes, buses, trains, scooters or walking.

Modal Filter

A modal filter is any measure, at a single point in a road, that allows the passage of some modes of transport but not others. One common type of modal filter allows walking, cycling and emergency vehicles to pass through, but stops other types of motor traffic at that point. Types of modal filter include a bollard, planter, gate, banned turns, cycleway filter, bus gate and cameras / enforcement. Modal filters offer the opportunity to significantly enhance the quality of the walking and cycling environment on both the street that is being filtered and adjacent roads.

Learn more about the role that modal filters can play in developing liveable neighbourhoods

Nationally described residential space standard (NDSS)

The national minimum space standard deals with internal space within new dwellings and is suitable for application across all tenures. It sets out requirements for the gross internal floor area of new dwellings at a defined level of occupancy as well as floor areas and dimensions for key parts of the home, notably bedrooms, storage and floor to ceiling height. However, these can only be applied where there is a local plan policy based on evidenced local need and where the viability of the development is not compromised.
