Construction Phase Traffic Management Plan

Transcription

1 Construction Phase Traffic Management Plan The Construction Phase Traffic Management Plan is in connection with the application for the development of a single Wind Turbine and Ancillary Works on land at Ridgecombe Farm, Lifton, Devon, PL16 0HD. General The site comprises part of a single field in agricultural use lying to the South East of Tinhay, as shown on the site location plan submitted with the application. The identified construction traffic delivery route is to leave the A30 at the junction with the A386 at Sourton Down. At the end of the slip road the route takes a right (onto the A386) and then immediately left onto the Bridestowe Road. The route follows this road through Bridestowe and on to Lewdown where there is a left hand turning at the cross roads sign posted to Chillaton. In Chillaton, the route takes the right hand turn sign posted to Lifton and then right at Router Cross which leads to the proposed turbine site entrance. Identified construction traffic route from A30 1

2 The yellow line indicates the route on the public highway from the A30. The last section of the route where it leaves the public highway is via field tracks which will be upgraded. Whilst there is an existing access from the public highway, a new temporary access will be constructed for the construction period to safely accommodate construction traffic and in particular delivery of the main turbine component parts. This will be reinstated after the construction period has completed. A permanent new access track will be constructed from the site entrance to facilitate access to the base of the proposed turbine during the operational period from the existing field gate, as illustrated in drawing ref: 1117/2836. There will be a hard standing area as shown on the development layout drawings submitted with the application. This is for the temporary storage of equipment and materials during construction and parking for site vehicles as shown on the proposed site layout plan. The hard standing area has been sized, and will be managed, to allow two or more vehicles to enter the site at the same time and for vehicles to turn around. A temporary turning head has also been shown on the layout plan for the construction period and then removed thereafter for vehicles to turn around so they can exit the site in a forward gear. The position of the access on a relatively open section of road (as shown below) provides adequate visibility in both directions for vehicles exiting the site. A combination of traffic control and banksmen in communication for all deliveries and vehicles exiting the site will be used. View of Site Entrance from the South East 2

3 View of Site Entrance from the North West Deliveries and Programme of Works Site deliveries of equipment to the site, utilising larger vehicles, will be phased over an eight week construction period, thereafter the majority of vehicles requiring access to the site will be small commercial vehicles and cars. All deliveries will be between 7.30am and 5.30pm. Deliveries to the site will be staged within this time period with drivers given specific time windows for arrival at site. The anticipated number and frequency of vehicle movements are set out below. A temporary wheelwash will be located on site during the construction periods, for all vehicles exiting on to the public highway in wet periods to avoid depositing mud onto the road. Similarly, in excessively dry periods the section of the highway immediately either side of the access will be swept if there is excessive dust. Due to the relative lack of neighbouring properties to the application site, it is not considered necessary to formally notify local residents of the construction phase period. However, as set out below appropriate traffic warning signs will be put in place (subject to prior notification of the Highways Authority). Access for emergency vehicles will be maintained at all times. Once the Programme of Works has been confirmed with the preferred installer including the delivery schedule, it will be submitted in writing for approval by the LPA and Devon and Cornwall Police Abnormal Loads team for approval prior to commencement of development. 3

4 Vehicle Movements Construction traffic will comprise delivery of the turbine and attendant infrastructure, concrete for the turbine base and sub-structure and materials for the access road. Delivery of the turbine and ancillary equipment to the site will comprise heavy and abnormal goods traffic and will comprise up to 10 vehicles over one or two days:- 1. The blades are fitted within transport frames, grouped into a set of three blades and are delivered in one telescopic semi-trailer truck load; 2. The blade hub, transformer and other auxiliaries are delivered in two truck loads; 3. The tower is delivered in two sections and two standard truck and trailer loads; 4. The nacelle is delivered in one truck load; 5. The large ring generator is delivered in one truck load; 6. One ton main crane and one 90 ton hydraulic tail crane. The materials for the new access road and hardstanding concrete for the turbine base/crane pad will generate approximately 10 HGV vehicle movements per day. Other vehicle movements associated with the development will comprise cars and small commercial vehicles for site workers. Post Development It is anticipated that the majority of vehicle movements to the site will be during the construction phase period for the delivery of materials and technical equipment (turbine, inverter station, mounting structure, cables and materials for the construction of the access track and hard standing areas). Once construction is complete, the site will require only periodic visits, for occasional repair and maintenance work. The existing access is considered sufficient for this purpose. As set out in the submitted Design & Access statement the field will remain in agricultural use post development therefore the access will be retained and maintained for that purpose. Contact A key site contact in respect of the construction phase will be confirmed and notified to the Highways department prior to commencement of development. 4
