  • Naval & Garrison Towns
    Naval & Garrison Towns Plymouth is possibly unique in the UK in that, at one time, it had all four armed forces stationed in the City, the Royal Navy, the Army, the Royal Marines and the Royal Air Force. The earliest reference to Plymouth’s military history is in 1287 when Edward I used the port as the assembly point for his fleet to carry an army to France. Plymouth Castle was built in the early 1400s. A series of gun platforms and block houses had been added along the waterfront by 1540. Drake’s Hoe Fort of the 1590s was largely replaced by the Royal Citadel after 1665. Across the mouth of the Plym, Mount Batten Tower probably dates from about 1650. The Naval Dockyard on the River Tamar at Plymouth Dock, later renamed Devonport, was developed from the 1690s. It had its own defences, mostly constructed in the second half of the 18th century. The Plymouth Division of Marines was established in 1755 with the Marine Barracks at Stonehouse being opened in 1783. Much later, in 1916-7, the Royal Naval Air Service became established at Mount Batten and operated seaplanes and flying boats from the Cattewater. This, in turn, became RAF Mount Batten. The strategic position of Plymouth made it an appropriate location for permanent military establishments including the Royal Citadel and the Naval Dockyard. Further fortifications, victualling facilities, barrack blocks for the men and military hospitals followed; these included the Royal Naval Hospital, the extended Royal Marine Barracks and Royal William Yard, all in Stonehouse. Devonport had the Dock Lines and their associated barracks, plus the Military Hospital.

  • 17 Socio-Economics
    MVV Environment Devonport Ltd Energy from Waste Combined Heat and Power Facility North Yard, Devonport 17 Socio-economics 17.1 Introduction 17.1.1 This chapter of the Environmental Statement (ES) assesses the socio-economic impacts of the proposed EfW CHP Facility at North Yard, Devonport. The chapter comprises: • An economic impact assessment, including employment impacts and income/supply chain multiplier effects; and • A review of other relevant socio-economic impacts. 17.1.2 This chapter describes the relevant policy context to demonstrate the fit of the proposal with objectives at the national and local levels; describes the assessment methods used; outlines the baseline conditions; and identifies the potential direct, indirect and induced impacts during construction and operational phases of the proposed development. 17.2 Planning Policy Context 17.2.1 This section reviews those policies that are relevant to the proposed development. National Policy 17.2.2 Planning Policy Guidance (PPG) and Planning Policy Statements (PPSs) provide a national guidance framework that sets out a range of principles and objectives on different aspects of land-use planning in England. 17.2.3 PPS1 'Delivering Sustainable Development' (Ref. 17-1) sets out the role of the planning system in the delivery of sustainable development. PPS1 encourages local authorities to recognise the wider sub-regional, regional or national benefits of economic development and consider these alongside any adverse local impacts. In addition, PPS1 seeks to: • Promote urban regeneration to improve the well being of communities, to include mixed- use developments in locations that allow the creation of linkages between different uses; • Provide development in locations which are easily accessible by foot, bicycle or public transport; and • Encourage the use of vacant and underused previously developed land and buildings.

  • The Next Stop
    THE NEXT STOP A PARENT’S GUIDE TO THE MAIN BUS ROUTES SERVING SECONDARY SCHOOLS IN PLYMOUTH SEPTEMBER 2014 This leaflet is designed to help parents when deciding which secondary school they would prefer their child to attend in September 2014. Most opt for the local school or community college, often within easy walking distance of home, but others choose one outside the immediate area and may, therefore, need information about the availability of bus services. All Plymouth secondary schools and community colleges are listed in this leaflet, together with the main bus routes that stop at, or very near to, each one and the local areas that each route serves. (The route number and operator are coded – for example, PC 50 is a Plymouth Citybus route serving Tor Bridge High from the city centre via Prince Rock and Leigham). For further information about routes and times contact:- First Devon & Cornwall: Telephone 0845 600 1420 Plymouth Citybus: Telephone 0845 077 2223 Warning This leaflet lists bus routes as at September 2013, but these may be changed or even cancelled at any time. The leaflet cannot, therefore, be a firm guide as to the bus services available from September 2014 onwards, nor does it imply that pupils using these services would be entitled to free school transport. Free School Transport and Concessionary Fares The current position is that Plymouth pupils are not normally entitled to free transport to a mainstream secondary school because they all live within walking distance – defined in law as 3 miles by the shortest available walking route – of a designated comprehensive school.

Mayflower Marina (Start) a,Ocean Quay At around 1877 a rail good shed was erected at friary leading to a goods line established beyond Devonport and Stonehouse to Ocean Quay. A few years after this in 1890 the quay was improved to take passengers. The idea was that Liner passengers would land by tender and be whisked to London and get there well in advance of those that stayed onboard and alighted at Southampton. There was then competition by the London and South Western Railway (LSWR) picking up from Ocean Quay with Brunel’s Great Western Railway (GWR) from Millbay.
