ABOUT THIS TECHNICAL MANUAL
The purpose of this technical manual is to act as a reference documentfordesignersanddevelopersoperatingwithinthepublic realm and private spaces of the City of London. Itprovidesguidanceonthematerialselection,visualaestheticandqualityexpectationsforsurfacematerials,streetfurniture,treesandplanting.ItistheexpectationthattheseelementswillofferalastingcontributiontothestreetsandspacesoftheCityasawholeandshouldberesponsiblysourced, robustlyimplementedandmaintainable.
The contents of this public realm Technical Manual are both prescriptive, where specific materials and elementsare generally to be used, as well as descriptive, outliningthe expectations on design, layout and other materialconsiderations.Thismanualshouldtobereadinconjunctionwith the City Public Realm SPD (adopted 2016) and will be updatedperiodicallyovertime.
Certain spaces within the City, often brought about bynew development, offer the chance for greater andmoredistinctive spaces, building upon and extending the richhistoryofchange.Insuchinstances,theremaybeexceptionalopportunities to vary the baseline guidance on materialselectionand introducemore tailoredandbespokedesignsolutionsextending the senseofqualityplacemakingwithintheCity.Suchexceptionalcircumstancesaretobediscussedwith the City Public Realm team at the City of London DepartmentoftheBuiltEnvionment.

The public realm provides a number of opportunities to introduce trees, planting and other natural elements. TheCity of London supports schemes that seek to increasenatural biodiversity, improve environmental conditions suchasair quality and safeguard thecontributionof thenaturalenvironment over the coming decades as climatic factorscontinuetochange.
Whilst much emphasis is rightly placed on the significantcontribution of green infrastructure to thecharacter of the public realm within the City, successfulplanting thatwill contribute in the long term is not withoutits challenges. Below ground conditions, often rich inarchaeology and an array of service utilities, present aconsiderable challenge to attaining appropriate rootvolumes for planting, particularlyfor trees. Careful treespecies selection focusing on growth habit, vigourand irrigation demand is critical inachieving long termsuccess.
This section identifies the technical requirements andconsiderations for successful plant selection and implementation.
