Chapters 1 to 11 Combined - Century City

CIVIL ENGINEERINGPRINCIPLESEngineering services at CenturyCity are a combination of privatelyowned facilities operated by theCentury City Property Owner’sAssociation (CCPOA), andmunicipal facilities operated by theCity of Cape Town. As a generalrule, specific and local ownershipof services need to be confirmedwith the CCPOA. A briefexplanation follows.RoadsThe external roads leading toCentury City are owned by theMunicipality or Province andmaintained according to theirstandards. Century Boulevard hasbeen constructed by the principaldeveloper of Century City, on landowned by the Municipality, buthas the status of a private road.This allows the Property Owners’Association to exercisemanagement control over theboulevard.Other roads within the project aregenerally private, being ownedand maintained by the PropertyOwner’s Association. The qualityof maintenance remains of a highstandard, but more flexibility ispossible with carriageway andsidewalk specifications.ParkingAll developments within CenturyCity require on-site parkingaccording to agreed standards.However it is envisaged that in thefuture there will be clusteredparking garages to provide off siteparking in selected areas of theproject. Parking standards include:Offices: 4 bays per 100m² GLARetail: 6 bays per 100m² GLAResidential: 2 bays per unit.Public TransportNormal public transport services(buses & taxis) currently operateto and from Century City. Thesewill be expanded on a phasedbasis, as demand increases overtime. At present, there are regularbus and taxi services to a publictransport interchange located inthe northern part of the site andwhich is accessed off RatangaRoad.Internal public transport services(shuttle buses) operated byCentury City Ltd. run along thecompleted section of the internalRing Road (Century Boulevard)between this facility, Canal Walkshopping centre and BosmandamRoad (pick up point at existingShell garage). In the future, theseservices will make use of thecompleted Ring Road system toserve all other developmentswithin Century City.A new transport interchange isproposed at the future SummerGreens station site on the Atlantisrailway line. This facility wouldserve as an interim bus & taxiinterchange prior to theupgrading of the Atlantis line to apassenger rail service, and wouldform an important interchangepoint for the internal shuttleservices.Planning for a new station andtransport interchange on theexisting Monte Vista railway line(Windermere station) hascommenced. Passengers willaccess Century City via a plannedoverhead pedestrian bridgeacross the N1 freeway.An additional station site on theexisting harbour line wasproposed as part of the originalplanning for Century City. Thisproposal may be pursued at somestage in the future in order toprovide a service betweenCentury City and Cape Town CBDand the V&A Waterfront.The Water SystemAn important design feature inCentury City is the water systemcomprising the central wetlandand a series of canals. Watercomes from a number of sources,including natural groundwaterand recycled water from thePotsdam treatment works. Aninnovative system of waterpurification has beenestablished to ensure that therecycled water is maintainedto an acceptable quality. Thisincludes a combination ofengineered and ecologicaltreatment by passing waterthrough filtration processes inthe wetland. The wetland doesnot therefore only function asa visual and environmentalasset, but is vital to thehealthy operation of the watersystems at Century City. It isessential that rubble anddebris are not deposited intothe canal systems to maintainwater quality.Stormwater ManagementThe wetland and canals aredesigned to accommodatenormal and surplusstormwater during major floodevents. However it isimportant to minimizepollution into these systems.For this reason a “low flow”and a “high flow” stormwatersystem has been designed,and needs to be respected bydevelopers.In order to the maintain highwater quality in the wetlandsystem, a low- flow systemhas been implemented. Thepurpose of the "low flowsystem" is to capture thehighly polluted runoff fromstorms of low intensity. ThisPLANNING PARTNERS: CENTURY CITY URBAN DESIGN FRAMEWORK October 2005 54 REVISION 1
