The main minerals extracted in Hertfordshire are sand and gravel, with smaller amounts of chalk and clay.
The county council produces a Minerals Local Plan which sets out the development planning framework for future minerals extraction and associated development whilst providing for environmental protection. This plays an important role in providing certainty and consistency for both industry and the general public. It contains minerals policies which are used to inform decisions on minerals planning applications in the county.

The Mineral Local Plan Review 2002–2016 was adopted on 27 March 2007.
The Minerals Local Plan contains preferred areas for sand and gravel extraction and policies for determining planning applications for mineral extraction.
The Plan is used to protect sand and gravel resources from non-minerals development, making them inaccessible for extraction or introducing development which is not compatible with mineral extraction nearby.
Maps within the Minerals Local Plan
We're currently reviewing our Minerals Local Plan.
We're planning to adopt our new Minerals Local Plan by Winter 2019.
The Secretary of State issued a Direction in respect of saving the Minerals Local Plan policies for decision making purposes which is in force until the Minerals Local Plan is reviewed.
Hertfordshire County Council has adopted a Supplementary Planning Document to the Minerals Local Plan.
The purpose of the document is to ensure that district and borough councils consult the County Council before determining applications for development in mineral consultation areas.
Much of Hertfordshire is underlain by sand and gravel resources. Allowing new building and other development in some areas could 'sterilise' the mineral deposits, either by making them inaccessible for extraction, or by introducing new activities such as housing into the area which would not be compatible with mineral extraction nearby.
Adopted mineral consultation areas are identified on county and district and borough proposals maps in their Local Plans.
The county council has a duty to produce an annual Local Aggregate Assessment (LAA). The purpose of this document is to monitor aggregate production and plan for a steady and adequate supply of aggregate in Hertfordshire (namely sand, gravel and clay within the county).
The county cannot source all of its aggregate requirements from within Hertfordshire and therefore must rely on external sources brought into the county via road or rail aggregate depots, before being transported to development sites. This is particularly the case for hard rock as this is not found within Hertfordshire.
The document details the supply and demand of minerals in the county, including:
- existing mineral sites
- sales and reserves
- aggregate apportionment levels
- recycled and secondary aggregates.
The LAA will inform the review of the Minerals Local Plan.
