Technical guidance notes and Manual for Streets

The technical guidance (TG) notes detail what the adoptable standards are within Hampshire. These documents form part of the framework of the material use policy and commuted sum policy. This aims to ensure appropriate use of materials and minimising long term maintenance costs. The guidance informs developers of what Hampshire County Council will accept on the highway network early in the design proposal stage.

The Technical Guidance Notes will replace most of the content of Hampshire County Council's companion guide to Manual for Streets, which has become out-of-date. When the technical guidance notes have been completed, we will review the companion guide to Manual for Streets and other guidance documents. If there is a discrepancy between the existing documents and the new technical guidance notes, then the new TGs take precedence.

TG18 Road Safety Audits

Due to the current Covid-19 restrictions on travel and 2m distancing the following procedure shall apply:

For Stage 1 and 2 Road Safety Audits: - These audits are still required for a design submission to pass inception, however we will accept the either of the following:

  • a) The lead auditor visits the site, takes photos/video and then supplies this information to the other auditor, so they are both reviewing the same information. The report will need to clearly state how the audit was undertaken
  • b) Both auditors visit the site, travelling independently and keep the 2m distance rule in place. Again report will need to clearly state how the audit was undertaken

For Stage 3 Road Safety Audits:

  • a) Given the recent increases in traffic level back towards normal volumes, Stage 3 audits will be classes as full audits. For S278 schemes, the RSA 3 and Designer's Response is required prior to the Certificate of Completion being issued. For S38 schemes, the RSA 3 and Designer's Response is required prior to the Part 2 Certificate being issued.
  • b) Prior to the audit taking place, the HDA Engineer will advise the auditors of any issues which they would like reviewed that have been raised during the construction period
  • c) Both auditors visit the site, travelling independently and keep the 2m distance rule in place
  • d) Both a day time & night time audit will be required
  • e) The Designers response will be required as normal and any agreed actions recorded formally in accordance with TG18
  • Please note that prior to adoption an RSA4 may be required but this will be reviewed on a case by case basis

Manual for streets

The Manual for Streets is the official government guidance for design, planning and approval of new residential streets and modifications to existing ones.

The Companion Document to the Manual for Streets was Hampshire County Council’s formal highways guidance on the Hampshire approach to street design. It did not replace or duplicate the national guidance but sat alongside it as local guidance.

Over time the County Council’s policies have evolved and been updated. This has resulted in parts of the Companion Guide becoming out-of-date. The Technical Guidance Notes will be the new source of information about adoptable standards in Hampshire.

Traffic management
Traffic signal controlled junctions

To assist developers in submitting appropriate drawings, typical layouts of preliminary and detail design drawings show the level of information required at A1 and A3 size for both design check stages.

*New* Trees on the highway

If a development is likely to impact trees on highway land, refer to Hampshire County Council's policy for the protection of highway trees affected by new developments. This outlines that compensation will be due for the loss of highway trees and the method for calculating the value.


For queries about applying this to your project, contact:

  1. the Design Check Engineer dealing with your S278 or S38 application (if you are a Developer or Developer’s Consultant)
  2. the Technical Guidance Note Specialist(s) (if you are a working within Hampshire County Council)

For queries or feedback on the Technical Guidance Notes, email stating the TG number in the subject line (eg. TG17 advice required about para 3.2)
