Policy KEY2 identifies that development proposals must meet the following specific requirements: a) the principal point of vehicular access will be off Holly Way with pedestrian access only via Meadow Close; b) the development shall deliver off-site traffic calming measures and a new pedestrian crossing across Colchester Road at the western end of the village; c) the development will provide a new village hall at the northern end of the development with access via Holly Way, the specification of which will be agreed with Elmstead Parish Council; and d) the development will set aside a minimum of 0.5 hectares of land as ‘green infrastructure’ that will incorporate allotments at the southern end of the site (to minimise visual impacts on existing properties in Meadow Way) and public open space alongside the new village hall to be transferred to Elmstead Parish Council for future management and maintenance, or suitable alternative management arrangements put in place to ensure long-term maintenance. 1 SAF/ss13498/P390/Reports DEVELOPMENT OFF HOLLY WAY, ELMSTEAD MARKET P390-01 Highways, Drainage and Utilities Position Statement January 2013 1.4 This Position Statement sets out baseline conditions and an assessment of the suitability of the site to deliver the development proposals set out in KEY2 associated with site access and accessibility by non-car modes, flood risk, drainage and utility infrastructure, and outlines opportunities for site provision. 2 SAF/ss13498/P390/Reports DEVELOPMENT OFF HOLLY WAY, ELMSTEAD MARKET P390-01 Highways, Drainage and Utilities Position Statement January 2013 2.0 THE SITE Site Location 2.1 The proposed allocation site is located on the western edge of the village of Elmstead Market, as shown at Plate 1. Plate 1: Site Location 2.2 The outer boundary of the site is formed by open fields (with recent tree planting) to the north and west and residential development to the east and south. Existing Site Use 2.3 The proposed allocation site has a total area of 3.1 hectares and is currently agricultural (arable) use. Surrounding Area 2.4 The surrounding area is predominately residential and agricultural. There is a limited range of facilities within the village including a 3 SAF/ss13498/P390/Reports DEVELOPMENT OFF HOLLY WAY, ELMSTEAD MARKET P390-01 Highways, Drainage and Utilities Position Statement January 2013 convenience store, one primary school (Elmstead Primary School) and one special school (Market Field School). 4 SAF/ss13498/P390/Reports DEVELOPMENT OFF HOLLY WAY, ELMSTEAD MARKET P390-01 Highways, Drainage and Utilities Position Statement January 2013 3.0 THE PROPOSED DEVELOPMENT 3.1 The proposed allocation is for residential development, with community uses and public open space, as referred to earlier at paragraph 1.3. 3.2 This statement is supported by an indicative layout plan at Appendix A, which illustrates the potential layout of development. 5 SAF/ss13498/P390/Reports DEVELOPMENT OFF HOLLY WAY, ELMSTEAD MARKET P390-01 Highways, Drainage and Utilities Position Statement January 2013 4.0 HIGHWAYS AND TRANSPORT Strategic Highway Network 4.1 The site is well connected to the strategic highway network (see Plate 2). The A133 passes through the village and connects to Clacton-on-Sea circa 16km to the south-east and Colchester circa 6km to the west. SITE Plate 2: Strategic Highway Network 4.2 Within the village, the A133 connects to the A604 via a 3-arm signal controlled junction. This links to the A120, which in-turn provides a connection to Harwich to the east and the A12 to the west. Local Highway Network 4.3 The highway network in the immediate vicinity of the site, at Holly Way and Meadow Close, is shown at Plates 3 and 4 respectively, with adopted highway shaded yellow. 6 SAF/ss13498/P390/Reports DEVELOPMENT OFF HOLLY WAY, ELMSTEAD MARKET P390-01 Highways, Drainage and Utilities Position Statement January 2013 Plate 3: Adopted Highway at Holly Way Plate 4: Adopted Highway at Meadow Close Holly Way 4.4 Holly Way is a circa 6m wide single carriageway residential road with footways on both sides (see Plate 5), and is subject to a 30mph speed limit. This provision is comparable to a Feeder Road as defined by the Essex Design Guide (EDG), which can serve up to 400 dwellings as a link or loop, and 200 in a cul-de-sac. 7 SAF/ss13498/P390/Reports DEVELOPMENT OFF HOLLY WAY, ELMSTEAD MARKET P390-01 Highways, Drainage and Utilities Position Statement January 2013 Plate 5: Holly Way 4.5 Holly Way effectively forms a loop with Lucerne Road, Wheatlands and Harvest Way, and connects to Church Road via a simple priority ‘T’ junction at its eastern end. Wheatlands connects to the A133 Colchester Road via Oatlands to the south-west of the ‘loop’. Therefore, these inter-connecting residential roads are accessed from two points on the wider network, and perform a link function. 4.6 The existing residential roads serve circa 300 homes and, therefore, an additional 100 homes could be served in accordance with guidance set out in the EDG. 4.7 North of Harvest Way, Holly Way becomes a cul-de-sac from which circa 80 homes are served, either direct from Holly Way or off Elmcroft. Therefore, up to an additional 100 homes could be served off an extension to Holly Way in accordance with EDG guidance. 4.8 Holly Way has no waiting restrictions, and most houses have off- street in-curtilage parking. 4.9 Elmcroft provides access to Elmstead Primary School. Some children are driven to/from the school and, as a result, it is understood that local roads can suffer short concentrated periods of congestion at the start (08:45) and end (15:15) of the school day due to on-street parking, as is the case with many primary schools. 8 SAF/ss13498/P390/Reports DEVELOPMENT OFF HOLLY WAY, ELMSTEAD MARKET P390-01 Highways, Drainage and Utilities Position Statement January 2013 Meadow Close 4.10 Meadow Close is a circa 4.8m wide single carriageway residential road with footways on both sides (see Plate 6), and is subject to a 30mph speed limit. This provision is comparable to a Minor Access Road as defined by the EDG, which can serve up to 100 dwellings in a cul-de-sac. Plate 6: Meadow Close 4.11 Meadow Close serves circa 40 homes and, therefore, an additional 60 homes could be served in accordance with guidance set out in the EDG. 4.12 Meadow Close has no waiting restrictions, and most houses have off-street in-curtilage parking. Church Road 4.13 Church Road is a circa 4.5m wide single carriageway road with a footway on its east side only (see Plate 7), and is subject to a 30mph speed limit. 4.14 It connects to the A133 Colchester Road at its southern end via a priority ‘T’ junction, located at a slight stagger to School Road opposite. At its northern end, Church Road provides access to a 9 SAF/ss13498/P390/Reports DEVELOPMENT OFF HOLLY WAY, ELMSTEAD MARKET P390-01 Highways, Drainage and Utilities Position Statement January 2013 farm and Elmstead Parish Church, with a private (gated) access road extending north. Plate 7: Church Road A133 Colchester Road 4.15 The A133 Colchester Road is a circa 6.7m wide single carriageway road, subject to a 30mph speed limit as it passes through the village and de-restricted (i.e. subject to the national speed limit 60mph for a single carriageway) either side (see Plate 8). It is designated a ‘Main Distributor Road’ in ECC’s Development Management Route Hierarchy, as it provides a strategic route between Colchester and Clacton-on-Sea.
