We continue to work towards creating a clear plan in terms of development for the borough.  In particular, we wish to identify any new previously developed (brownfield) sites which may be available for redevelopment as part of an update of the Housing and Economic Land Availability Assessment (HELAA).

We undertook a new Call For Sites, which was launched in October 2022, to provide a clear understanding of what land may potentially be available, suitable and achievable for future housing (including self-build and custom-build housing, as well as Gypsy and Traveller pitches) and economic development over the next 15 years.  The Call for Sites also provided an opportunity for land for Biodiversity Net Gain, flood risk management and other green/blue infrastructure to be submitted.

Those submitting sites for consideration were required to complete a HELAA questionnaire, together with a site plan with the site boundaries clearly indicated. View a copy of the questionnaire (DOCX 189KB)

Completed form(s) (DOCX 203KB) had to be returned to local.plan@hertsmere.gov.uk by midday on Thursday 22 December 2022.   Responses for any new sites received after this date cannot be guaranteed for consideration within the updated HELAA.  Details of the submissions will be published on this page in due course. 

Important: The submissions which we have received are not Hertsmere proposals. Instead they are proposals put forward by site promoters and land owners based on individual representations.

A draft revised HELAA Methodology (DOCX 132KB) was issued alongside the Call for Sites with comments invited by 22 December 2022.

stakeholder list (DOCX 20KB) sets out who was notified directly about the call for sites and HELAA Methodology.

A complete list of sources of sites suggested in the NPPG (PDF 57KB)

A pro-forma (DOCX 38KB) to enable assessment and survey work to be undertaken in an integrated way has been produced. New HELAA sites are being surveyed and assessed using this pro-forma.


'Call for Employment Sites' 2021

A 'Call for Employment Sites' was previously issued to identify a number of new sites being promoted for economic development, which have not been previously submitted to us for assessment. The identification of such sites will, if included in our Local Plan, help underpin the borough's economic recovery from the impact of the Covid-19 pandemic.

Important: The submissions included within the ‘Call for Employment Sites’ are not Hertsmere proposals. Instead they are proposals put forward by site promoters and land owners based on individual representations.

The ‘Call for Employment Sites’ process closed on 18 March 2021.  A summary of the individual submissions received, was taken to member planning panel on 30 March 2021 and the presentation can be found here. (7.19KB) All of the individual site submissions can be found below and any additional supporting technical documents submitted with these responses can be viewed on request.

Further information on this process is provided within the Frequently Asked Questions  document (599kb pdf)

Information we have already received on sites, following our previous Call for Sites, is set out in the latest Housing and Employment Land Availability Assessment report published in 2019 (see below). The Council are currently in the process of considering the submissions and will provide an updated assessment of any new sites promoted through the 2021 Call for Employment Sites Process in due course.

HELAA Update May 2018

We have published an interactive map showing the sites which have been promoted either through the Call for Sites in 2017 or the Issues and Options consultation in 2017.

The mapping includes links to basic information about the site and to the submitted site plan and questionnaire.

We are treating all submissions in exactly the same way and considering them all against the same criteria, whether they were submitted through the Call for Sites, Issue and Options, or both, and whether or not they have been submitted with a lot of supporting information or with none.
