Evidence Base for the New Local Plan

We are currently working on a new Local Plan for the borough, which includes gathering a substantial amount of new and updated evidence. New documents will be added to this section as they become available.

South West Hertfordshire Strategic Housing Market Assessment (SHMA)

When the Core Strategy was adopted in 2013 we undertook to review housing and employment development needs within three years to help inform future plan-making. The council jointly with Dacorum, Three Rivers and Watford Council's commissioned consultants in 2015 to prepare two interlinked studies, the SHMA (produced by GL Hearn) and the Economic Study (Regeneris, assisted by GL Hearn).

The purpose of the SHMA is to assess future development needs for housing (both market and affordable) across the relevant housing market area (HMA). Based on the evidence, the South West Hertfordshire HMA is defined as covering the four commissioning authorities, plus St Albans District.

The SHMA considers housing need arising over the 2013 to 2036 period, to inform local plans. It considers the need for different types of housing and the housing needs of different groups within local communities.

South West Hertfordshire Economic Study

The Economic Study provides comprehensive economic baseline and growth scenarios for South West Hertfordshire. The study identifies the scale and characteristics of employment growth that the functional economic market area (FEMA) might plan for over the 2013-2036 period, and the requirements for employment land and floorspace that this entails. In light of the evidence, the SW Hertfordshire FEMA covers the same area as the HMA defined in the SHMA i.e. the commissioning authorities and St Albans.

The Economic Study provides a high level review of some existing employment areas and potential future sites. It also considers whether there is likely to be sufficient land supply to meet the needs of the South West Hertfordshire economy.

Because it is so important to understand the future need for homes and jobs, the studies have been subject to extensive consultation with technical stakeholders. This has included a workshop, for which a separate report has been published.

The SHMA does not set housing targets, nor does the Economic Study set targets for job growth or floorspace increase. Both studies provide important inputs into the setting of these targets.  However, the actual targets will be set by each local authority in future local plans. When setting these targets, the authorities will take account of the SHMA and Economic Study and a range of other factors.  These factors will include the supply of land for new development, the Green Belt, local infrastructure capacity and environmental constraints. These factors may limit the amount of development which can be accommodated sustainably.

The targets included in local plans may also be affected by the outcome of discussions under the Duty to Co-operate between the commissioning authorities and neighbouring and nearby authorities.

Housing and Economic Land Availability Assessment (HELAA)

We are responsible for preparing and keeping up to date a HELAA to inform future plan-making in Hertsmere. The HELAA is a technical study that provides an overview of Hertsmere’s housing and economic land supply to meet the borough’s future development needs. It is kept under regular review to keep up to date on where development potential may exist and may contribute towards the creation of sustainable, mixed communities.Prior to the introduction of the National Planning Policy Framework in 2012, this document was referred to as the Strategic Housing Land Availability Assessment (SHLAA).

The HELAA is used to inform our planning policies and choices on specific allocations of land for development. However, it has no policy status in allocating land for development or on the decisions we make on individual planning applications.

Strategic Housing Market Assessment 2010

The 2010 Strategic Housing Market Assessment (SHMA) considered how the local housing markets operate and assesses housing need and demand in the area. The SHMA was produced in conjunction with us, Hertfordshire County Council, Dacorum Borough Council, St Albans City and District Council, Three Rivers District Council, Watford Borough Council and Welwyn Hatfield Borough Council, to consider the wider housing market.

Please see the 2016 SHMA at the top of this page.

Housing Needs Survey

We, along with Welwyn Hatfield District Council, jointly commissioned David Couttie Associates to examine the levels of housing demand and supply in each district.

Gypsy and Traveller Accommodation Needs Survey

The Centre of Urban and Regional Studies at the University of Birmingham undertook an assessment of need for gypsy and traveller sites and pitches in 2005. This is a joint project between us, Hertfordshire County Council, Dacorum Borough Council, St Albans City and District Council, Three Rivers District Council and Watford Borough Council.

Employment

Hertfordshire / London arc - jobs growth and employment land

Centennial Park ElstreeThis study's purpose is to provide a sub-regional overview of future

requirements for employment land, comprising factories, warehouses and offices, up to 2026. It follows up earlier work on the central Hertfordshire Employment Land Review. Roger Tym & Partners were commissioned to undertake this study in February 2008 by the district and borough councils of the Hertfordshire / London arc, comprising of us and Broxbourne, Dacorum, St Albans, Three Rivers, Watford and Welwyn Hatfield. Together with Brentwood and Epping Forest in Essex, these local authority areas make up the London arc sub-region, as defined in the current Regional Spatial Strategy, the East of England Plan.

Employment site allocations report

The aim of this study was principally to assess the boundaries of allocated employment areas and make recommendations in respect of whether they should be altered before the sites are considered for reallocation. It also sought to recommend whether existing safeguarded employment land adjoining Potters Bar should be retained, and whether any additional land should be safeguarded, in addition to discussing alternative options.

Retail

Retail topic paper  

The topic paper set out the existing evidencelocal shops in Darkes Lane, Potters Barbase regarding the retail needs assessments that covers Hertsmere, but have been prepared by authorities that adjoin Hertsmere. This justifies our position regarding the informed decision not to allocate any major retail sites itself and the choice not to undertake an additional full retail needs / capacity assessment.

Green Spaces Assessment

High quality green space has a positive impact on the urban environment. Green spaces of different sizes and types provide ‘green lungs’ to an urban area, assisting with nature conservation, biodiversity and improvements to air quality. The assessment looks at these aspects for future planning policy.

Building standards and design

Building Futures

Building Futures (opens in new window) is a web-based guide, designed to provide practical, user-friendly and up-to-date guidance on how to make development in Hertfordshire more sustainable and of a higher quality in design terms.

Bushey Heath MOD Housing Special Character Area

This report assesses the Bushey Heath MOD housing area and concludes that it comprises an area of special interest by virtue of the environmental quality. This is because of the following features: • A cohesive feel due to the lack of individual alterations ad extensions to the dwellings. • Generous plot sizes, which are set back from the main road, and general spacing between buildings which enhances the feeling of spaciousness. • A lack of unsympathetic hardstanding at the front of the buildings and numerous trees.  Designation as a Special Character Area would not restrict development as tightly as if it were located within a Conservation Area, however it would guide new development to in order to respect or enhance the character, appearance and environmental quality of the area.
