10.116 It is proposed that there will be a split responsibility for surface water storage between private and public lands by requiring all developments to limit discharges to the public system to an absolute maximum of 68l/s/ha (approximately 50% of design peak brownfield runoff rate for critical storm event) irrespective of tidal phase. 10.117 Development proposals will have to demonstrate site run-off flow rates of 50% of greenfield run- off rate to the public SuDS. Developments will be required to ameliorate the private 50% rainfall on-site utilising sustainable urban drainage system solutions (see Objective 9.4: Sustainable Urban Drainage Systems and para. 11.259).
The key guidance for each character area is set out below.
10.121 The guidance may be updated by masterplans prepared during the lifetime of the Plan. This guidance is indicative and development proposals must demonstrate high quality placemaking and must comply with other objectives of this Plan. It should be noted that building heights are expressed in residential storey equivalents. 10.122 All finished floor level guidance provided in Tables 10.6 to 10.13 are subject to final levels pending the completion of the South Docks Drainage Strategy.
Basements and Structural Design Strategies 10.118 Based on the findings of the preliminary
Land Use Targets
10.123 The land use targets reflect the intended nature of the City Docks, including a city centre extension and a residential neighbourhood. The targets provide an overview for the Character Area. 10.124 Applicants for development proposals must demonstrate how the proposal contributes towards the achievement of the land use targets for each character area. 10.125 Deviations from the land use targets may be considered on their merits where justified, including where: 1. a proposed development is of strategic significance. 2. a proposed development is a catalyst development of civic significance 3. a proposed development is deemed to be of exceptional design quality.
hydrogeology study completed as part of the Strategy, it will be vital to protect the integrity of the existing aquitard (alluvium) soil layer as part of the proposed redevelopment of the South Docks. The nature of the ground conditions and height of the buildings will require piling, and so the detailing of this in a way which maintains the integrity of the clay layer is vital. Equally, deep excavations for basements should be avoided. 10.119 Development proposals must demonstrate that piling / structural design avoids penetrating the aquitard soil layer in any planning application. Guidance for the City Docks Character Areas 10.120 The City Docks has been divided into character areas to enable the creation of coherent precincts with distinct characters to create strong places and neighbourhoods (see Character Areas, above).
