1 Doc ref: CBO Daniel O Brien United Utilities Property Services Grasmere House Lingley Mere Business Park Lingley Green Avenue Warrington WA5 3LP 23 rd June 2017 Dear Daniel MANCHESTER ROAD, BOLTON: INITIAL TRAFFIC GENERATION ANALYSIS CBO Transport Limited [CBO] has been commissioned by United Utilities Property Services [UUPS] to provide preliminary advice in relation to development opportunities at their Manchester Road, Bolton site. Existing site Barnett House 53 Fountain Street Manchester M2 2AN T: F: The site currently houses two commercial properties; the Depot building to the north and Meridian Court to the south. Based on information that is currently available, it is understood that the gross floor area of the Depot building is circa 7.060sq.m and that the gross floor area of Meridian Court is circa 3,565sq.m. The Meridian Court building accommodates B1 office use, whilst the Depot building includes a mix of office, stores, workshop, kitchen and a restaurant. These buildings are served by circa 500 parking spaces within the site. The primary access to this parking is via a ghost island priority junction arrangement with Manchester Road which enters the site between the two buildings. There is also a second priority junction access from Manchester Road towards the north of the site serving some parking outside the Depot building. This is an in only access, with vehicles being required to exit via the main access. Proposals Whilst there is currently no fixed scheme for the site, initial consideration has been given to the following two development scenarios: Scenario 1: A commercial scheme comprising a circa 1,500sq.m discount food store, a circa 280sq.m fast food drive-thru restaurant and a circa 1.4ha car showroom site; and Scenario 2: A 110 dwelling residential scheme. It is assumed that either of the schemes would be served via a single access from Manchester Road, likely using an access in the same location as the existing access. The form of this access is still to be determined and will need to be investigated once a final scheme content is known. Purpose / Scope of Letter In light of the above, the purpose of this letter is to summarise the findings of the initial traffic generation analysis exercise carried out in association with these potential schemes, how they compare with the existing uses at the site assuming they were fully occupied and what this means in terms of traffic analysis work going forward with an application.

2 Traffic Generation: Existing Uses As set out above, it is understood that the gross floor area of the Depot building is circa 7.060sq.m and that the gross floor area of Meridian Court is circa 3,565sq.m. The Meridian Court building accommodates B1 office use, whilst the Depot building includes a mix of office, stores, workshop, kitchen and a restaurant. Page 2 Project: Manchester Road, Bolton Doc Ref: CBO In light of the above and given the mix of uses in the Depot site, two theoretical scenarios have been considered in relation to existing traffic generation: Scenario 1: A scenario whereby 100% of the Meridian Court and Depot buildings are occupied by B1 office use; Scenario 2: A scenario whereby 100% of the Meridian Court building is occupied by B1 office, but where circa 75% of the Depot building is occupied by B1 office with the remaining circa 25% occupied by B2 General Industrial use. Based on these theoretical scenarios, the attached Table 1 shows the trip rates derived from TRICS for these uses, whilst the attached Tables 2 and 3 show the resultant traffic generation for each scenario during the typical weekday morning (8:00 9:00) and weekday evening (17:00 18:00) peak periods. Note that these trip rates are generic, typical trip rates and may need to be refined in due course. The floor areas may also need to be amended if more detailed information becomes available regarding floors areas and their permitted uses under planning. Note also that it is assumed that these existing uses result in no traffic generation at the site during the weekend peaks. Traffic Generation: Proposed Uses As set out above, initial consideration has been given to the following two development scenarios: Scenario 1: A commercial scheme comprising a circa 1,500sq.m discount food store, a circa 280sq.m fast food drive-thru restaurant and a circa 1.4ha car showroom site; and Scenario 2: A 110 dwelling residential schemes. Based on these scenarios, the attached Table 4 shows the trip rates derived from TRICS for these uses, whilst the attached Tables 5 and 6 show the resultant traffic generation for each scenario during the typical weekday morning (8:00 9:00) and weekday evening (17:00 18:00) peak periods. These tables also show the resultant traffic generation during the identified Saturday hours. Note again that these trip rates are generic, typical trip rates and may need to be refined in due course once there is more certainty on the scheme. Traffic Generation Comparison Based on the traffic generations referred to above, the attached Table 7 compares the traffic generation of the existing uses with those of the proposed uses. Scenario 1: Commercial Scheme As can be seen from the attached Table 7, based on the information available and the assumptions made at this stage, the proposed Scenario 1 commercial scheme would generate less traffic at the site than the existing uses could potentially generate during the weekday morning peak under both of the existing use scenarios that have been considered. During the weekday evening peak period, the Scenario 1 commercial scheme would generate between approximately 0 and 25 two way trips more than the existing uses could potentially generate depending on the scenario used for the existing uses. With regard to the Saturday peak, the commercial scheme would generate traffic that is all effectively new to the site.

3 Scenario 2: Residential Scheme As can be seen from the attached Table 7, based on the information available and the assumptions made at this stage, the proposed Scenario 2 residential scheme would generate less traffic at the site than the existing uses could potentially generate during the weekday morning peak under both of the existing use scenarios that have been considered. It would also generate less traffic at the site than the existing uses could potentially generate during the weekday evening peak under both of the existing use scenarios that have been considered. Page 3 Project: Manchester Road, Bolton Doc Ref: CBO With regard to the Saturday peak, this would not normally be considered as part of a residential development assessment. Scope of Traffic Related Work Required Going Forward Scenario 1: Commercial Scheme Based on the findings set out above it is considered that, if UUPS progress with a commercial scheme, Saturday traffic assessments will need to be undertaken as part of a Transport Assessment. For completeness, we would also suggest that weekday evening assessments (likely on a Friday) also be carried out, particularly in the context of understanding how the site access would operate. With regard to the scope of these assessments, these will need to be discussed with Bolton Council when considering the scheme as part of the pre-application process. However, at this stage, we would suggest that these will need to include: The site access off Manchester Road; The Manchester Road / Green Lane traffic signal junction to the east of the site; and The Manchester Road / Raikes Lane traffic signal junction to the west of the site. Bolton highways may also request that one or two other junctions also be considered further north along the Manchester Road corridor. Any traffic counts that are required following discussions with Bolton highways will need to be carried out in September when schools return from the Summer holiday period. Scenario 2: Residential Scheme Based on the findings set out above it is considered that, if UUPS progress with a residential scheme, no off site traffic assessments will need to be undertaken as part of a Transport Assessment. However, for completeness, we would suggest that weekday morning and evening assessments be carried out at the site access off Manchester Road in the context of understanding how the site access would operate.
