1 INTRODUCTION

Canham Consulting Ltd have been commissioned by The Lind Trust to produce a

Transport Assessment Addendum in support of a planning application for commercial/

business use at the site located on Former St Andrews Hospital, Northside, St Andrews

Business Park.

The addendum follows the Transport Assessment (TA) undertaken by Richard Jackson

Ltd for the previously consented development (planning ref: 2013/0486). The reason for

the addendum is that since the original TA was undertaken several planning policies

have changed and some time has passed resulting in the need for a validation count to

verify the original traffic count data.

This report then reviews the original TA to identify what areas need to be renewed, then

provides the additional information needed.

2 DEVELOPMENT DESCRIPTION & ACCESSIBILITY

2.1 Proposed Development

The proposed development consists of commercial and business units on what was the

former Saint Andrews Hospital. Since the time of the original TA, the original buildings

have been demolished with only the clock tower and central section remaining. The

demolition works have had no impact on the access or existing loop road.

The proposed development remains as per that presented within the original TA. The

proposed development floor space is 12750m2 equal to the previous use. Appendix A

contains the proposed development plan.

It is proposed that the site will be accessed from Northside as the current development is

accessed. There are no proposed changes to the access arrangements and facilities to

allow movement to the Norvic Clinic to the north of the site will remain.

Parking standards for the proposed development uses have not changed since the

original TA.

2.2 Public Transport

As covered in the TA, there are four bus stops within the vicinity of the site. These are:

Thorpe St Andrew, adjacent Business Park’ on the Yarmouth Road. This is next to

the main entrance to the business park approximately 400m south of the site.

‘Broadland Business Park, adjacent Old Chapel’ accessible by foothpaths and is

approximately 400m south east of the site.

‘Thorpe St Andrew, adjacent Sainsburys’ is adjacent Sainsburys supermarket and is

accessible by footpath/footbridge over the railway line, 700m south west of the site.

‘Dussindale Park, opposite Cavalier Close’ is adjacent to the playing fields to

Dussindale Primary School and is approximately 800m north west of the site. This is

also accessible by footpaths.

The bus services that serve the above stops are summarised in Table 1. Timetables can

be found online at www.travelineeastanglia.co.uk.

3 TRAFFIC GENERATION AND ASSESSMENT

The development proposals remain the same as previously therefore the trip generation will

be the same as presented in the original TA. For ease, the previous and proposed trip

generation is summarised below.

3.1 Previous Trip Generation

The previous trip generation as derived using TRICs data. The former use had a floor

space of 10,000m2. Table 2 shows the trips, trip rates and comparison trip rates for a

building of 12750m2.

Trip rate per 100m2 1.69 0.8 0.7 1.36

Trips for 12750m2 of

previous use 215 102 89 173

Table 2: Previous Trip Generation

3.2 Proposed Trip Generation

The site is proposed to accommodate 12,750m2 of office space. Based on Norfolk County

Council’s parking standards 2007, this would equate to 425 spaces which has been

identified within the original TA.

The proposed trip generation for office space has been derived using NCC’s method of

80% of vehicles which will park at the development are likely to arrive between 0800-0900

hours. This is the same method as the original TA. Table 3 summarises the proposed trip

generation for the AM peak period.

Office Trip Generation Calculation 80% x 425

16% of arrivals (i.e 16% of 340)

Number of Vehicles 340 54

Table 3: Proposed Trip Generation

It can be seen from Table 3 that the total number of two way trips in the AM peak hour is

394.

3.3 Traffic Count

The original TA undertook a traffic count of the Yarmouth Road/Northside/Southside

roundabout junction on 6 March 2013. Following discussion with Norfolk County Council

(NCC) to discuss the scope of works for this addendum report it was agreed to undertake a

validation traffic count for the AM peak hour of 0800-0900 hours.

A validation traffic count was undertaken on Tuesday 12 July 2016. The traffic count data is

included within Appendix B.

3.4 Traffic Impact

To assess the likely impact the proposed development will have on the local highway

network the previous use trips will need to be offset against the proposed trips. This means

that the net effect will be 77 new trips (394 - 317).

The impact that the proposed development site traffic may have will be the additional

generated traffic in the AM peak which has been calculated as 77 two way trips. The impact

of these trips can be assessed against the number of trips already using the main access of

the highway network at the Yarmouth Road/Northside/Southside junction.

The total number of trips, on the Yarmouth Road/Northside junction in the AM peak were

counted as summarized in Section 3.3 above. The total number of vehicles (excluding

pedestrians and cyclists) from the 2016 count was 2425. The proportion of the additional

impact can therefore be calculated as (77/2425) x 100 = 3%. This is the same impact as

derived in the original TA and 2013 counts. (2013 impact was (77/2536) x 100 = 3%.)

This impact of 3% is relatively small and NCC’s guidance is such that any impact less than

5% is negligible and therefore no mitigation is required.

The NPPF guidance on impact states that:

‘All developments that generate significant amounts of movement should be

supported by a Transport Assessment. Plans and decisions should take account of

whether:

The opportunities for sustainable transport modes have been taken up depending

on the nature and location of the site, to reduce the need for major transport

infrastructure;

Safe and suitable access to the site can be achieved for all people; and

Improvements can be undertaken within the transport network that cost effectively

limit the significant impacts of the development. Development should only be

prevented or refused on transport grounds where the residual cumulative impacts of

development are severe.

It can therefore by seen that the impact is not severe and in fact very small at only 3% of the

total movements at the sites initial connection to the highway network.

4 SUMMARY

The development proposals are the same as the previous application with proposals to

change the use to B1 office and modify the existing building to provide 12,750sqm of office

use.

The traffic impact assessment has demonstrated that the change of use could generate

approximately 3% additional traffic during the AM peak hour, which is a small amount and

not deemed significant. It can be concluded that the proposal will not have a detrimental

impact on the highway network.

Given the above, it is considered that there are no transport related reasons for an

objection to be raised to this planning application.
