1 Supplementary Transport Analysis

Introduction

1.1 This Technical Note has been prepared to consider the traffic implications of revisions to the development proposals at Selby Paper Mill.

1.2 The note should be considered alongside the following previously submitted transport reports:

I Supplementary Transport Statement, April 2013

I Supplementary Transport Assessment, May 2012

I Transport Assessment, July 2010

Revised Development Proposals

1.3 The change in development proposals is summarised in Table 1.1 below. In effect, there is a reduction in overall dwellings, and a revision to the use of the feature building.

TABLE 1.1 REVISIONS TO THE DEVELOPMENT PROPOSALS

Land Use Allocations (April 2013) Revised Allocations

199 houses 250 houses

172 flats 42 flats

Feature Building

- 30 apartments

- 1200m2 leisure

- 600m2 bar/restaurant

Feature Building

- 10 apartments

- 520m2 office

- 260m2 retail

- 260m2 bar/restaurant

112m2 leisure (at marina entrance)

7 retail units 7 retail units

32 berth marina 32 berth marina

1.4 A revised layout diagram is provided in Appendix A.

1.5 It is now proposed that the feature building is divided between retail and bar/restaurant uses on the ground floor, with offices occupying the first floor and apartments on the upper floors.

1.6 This represents the re-introduction of office use to the site, which has not been included since the July 2010 analysis.

Car Parking Provision

1.7 Table 1.2 provides a summary of the North Yorkshire County Council parking standards1 applicable to this development and the maximum number of car parking spaces that should be provided.

TABLE 1.2 CAR PARKING GUIDELINES

Land Use NYCC Parking Standard Maximum provision

Residential - houses 250 units 3+ beds – 2 spaces per dwelling 500

Residential – flats 52 units 1&2 beds – 1 space per dwelling 52

Offices 520m2 1 space per 40m2 GFA 13

Retail 1,100m2 1 space per 40m2 GFA 28

Restaurant 260m2 1 space per 10m2 + 1 per 4 staff 26 + 2

Leisure 112m2 Not directly applicable 1 (assumed)

Marina 32 berth n/a n/a

Total Vehicular Parking (maximum) 622

1.8 Parking for the houses will be provided within each plot, and underground parking will be provided for the 28 riverside apartments. Excluding these elements from the above provisions, leaves a maximum allocation of 94 spaces for all other site uses. Previous analysis has also assumed a further 24 spaces for marina uses.

1.9 A total of 100 parking spaces is allocated in the latest layout, with the majority located towards the centre of the site, close to the feature building, retail and marina. This is 18 spaces short of the maximum number of spaces indicated by the parking guidelines. As stated in earlier assessments, the retail element of the site will largely serve residents and commercial users of the site, particularly those using the marina. This will also apply to the restaurant use and, as such, the maximum number of parking spaces at each site will not be required.

1.10 The guidelines recommend additional residential parking for visitors, at a ratio of 1 space per 5 dwellings. For a total of 302 dwellings, this would equate to a further 60 car parking spaces. The internal road network will be greater than 5.5m in width and therefore, as suggested in the guidance, provision for visitors will be allocated within the main residential area of the site.

Impact on Trip Generation

1.11 The previous Supplementary Transport Statement from April 2013, outlined trip generation forecasts set out in Table 1.3 below. It has consistently been assumed that the retail element of the development will be “ancillary to commercial uses on site”, generating trips from within the development and pass-by trips already

on the network. As such, the retail proposals will not generate any new trips to the site.

TABLE 1.3 TRIP GENERATION FORECASTS (85TH %ILE TRIPS) – PREVIOUS DEVELOPMENT PROPOSALS

Land Use Unit AM Peak PM Peak

In Out In Out

Residential: Houses Number of dwellings 59 75 103 41

Residential: Flats Number of dwellings 30 61 67 51

Leisure 100m2 GFA 11 6 28 13

Marina Number of berths 3 1 2 5

Total Generated Trips 104 149 242 139

1.12 Apart from the number of berths in the marina, each element of the site has been revised in the current proposals. To allow a comparison of the previous trip generation forecasts with those we might expect from the revised proposals, the trip rates in Table 1.54 have been used. For each land use, the trip generation rates have been taken from previously submitted transport reports for the site.

TABLE 1.4 TRIP GENERATION RATES


In Out In Out

Residential: Houses Number of dwellings 0.321 0.405 0.556 0.222

Residential: Flats Number of dwellings 0.150 0.300 0.333 0.250

Office 100m2 GFA 2.862 0.345 0.300 2.491

Bar/Restaurant 100m2 GFA 0 0 6.166 4.372

Leisure 100m2 GFA 0.941 0.529 2.313 1.063

Marina Number of berths 0.103 0.029 0.067 0.164

1.13 The resulting change in trip generation forecasts for the revised development are given in Table 1.5. Comparing these with the previous forecasts in Table 1.3, we see that trip generation forecasts are reduced under the revised proposals, particularly in the PM peak where total two-way trips are reduced by more than 100 trips.

Total Commercial Trips 19 4 23 30

Trip Distribution

1.14 Although the revised proposals re-introduce a small amount of office use to the site, there is no reason to change the trip distribution assumptions presented in previous transport assessments. Similarly there has been no update to base year flows or general traffic growth assumptions.

1.15 The following figures are a repeat of those presented in the April 2013 Supplementary Transport Statement and show the distribution of trips on to the local network (Figures 1.1 to 1.4) and the impact on traffic forecasts in the 2017 assessment year. Where applicable, each figure indicates the difference to the April 2013 forecasts.

1.16 In each case, forecasts based on the current land use mix are lower than previously presented.

Conclusion

1.17 The revised proposals for redevelopment of the Selby Paper Mill site will result in fewer trips than previously forecast, particularly in the PM peak hour where total two-way trips are predicted to reduce by more than 100 trips.

1.18 When added to forecasts of general traffic in 2017, flows are lower than those previously assessed and, subject to previously agreed mitigation, there are no additional highway reasons why planning consent for the proposed mixed use development at the former Paper Mill in Selby should be withheld.
