Site Analysis and the Blank Map

SLOP2418 — Urban Design Studio
Week 1 · Marisol Quaye · 22 February 2027

direct readout · derived measure · worked hypothetical

How this studio works

  • One student, one save file, one district, Weeks 1 to 12.
  • Everyone builds on the same site: the standard map issued today.
  • Twelve lectures, twelve studio sessions, three assessed pin-ups with a jury.
  • Assessed submissions include screenshots, a memo and the save. Week 1 uploads an untouched archive and a one-page site report.
  • The software of record is Cities: Skylines II. No simulation-altering mods, no unlimited money, no unlock-all.

Survey before plan

Survey before plan.

— the dictum associated with Patrick Geddes, Cities in Evolution (1915); not a verbatim line from the text, but the working principle it argues for

Today’s session ends with a site report and no roads.

What “good” has meant before

Lynch’s five dimensions of good city form, with the two meta-criteria, set as a list:

  • vitality — the settlement sustains the biology of its inhabitants
  • sense — it can be perceived and structured in the mind
  • fit — its spaces match the behaviours people actually perform
  • access — people, goods and information can reach what they need
  • control — those who use a space have some say over it
  • and across all five: efficiency and justice

Kevin Lynch, Good City Form (1981).

Three metrics

fiscal performance mobility performance livability

Every lecture. Every studio session. Every criterion on every mark sheet.

Fiscal performance

Fiscal performance — whether the district can pay for what it has built, and keep paying as it grows.

  • Read it in: the economy panel’s monthly balance; the service budget sliders and the per-service expenditure lines beneath them; road and building upkeep; outstanding loans and their repayments; the tax rates set per zone type and per resource.
  • The jury asks: what does this district cost per month at the service level you are claiming, who pays that, and what does the number do when the population you have zoned for actually arrives?

Mobility performance

Mobility performance — whether people and goods complete their trips at an acceptable cost in time, at the hour the trips are actually made.

  • Read it in: the traffic info view’s flow and volume overlays; the road-level traffic readout; public transport line passenger counts, vehicle loads and stop waiting times; the path taken by a selected citizen or delivery vehicle when you follow it.
  • The jury asks: for one named origin and one named destination in your district, how long is that trip at the morning peak, by which mode, and what is the second-best mode when the first one is full?

Livability

Livability — whether the place is worth being in for the people already there, independent of how many more arrive.

  • Read it in: citizen well-being and health figures; the happiness readout on individual buildings; the land value overlay; the service coverage overlays — health, education, parks, police, fire, garbage, mail; and the four pollution overlays — ground, air, noise and water.
  • The jury asks: name the worst-served block in your district, say what it is short of, and say what you chose to spend the money on instead.

How the three are read, and where they are marked

  • All three are read over time, not at a moment. A screenshot is evidence of a state; the studio marks a trend.
  • Take every reading at the same in-game hour. The studio convention is 08:00, and the memo says which hour the reading was taken at.
  • Where two metrics conflict, name which one you traded and why. A plan that claims all three must account for costs and who benefited.

McHarg’s layers, and where they live

Gold is what the site gives. Black is what somebody drew.

Kerrow Basin in Lynch’s five terms

Lynch termOn this site
PathThe highway spur south from Dunthorpe; the rail line along the terrace
EdgeThe River Kerrow; the break of slope at the foot of Verrall Ridge
DistrictHalstead Reach, Verrall Ridge, Ombersley Flats
NodeDunthorpe interchange; Thackray Cut, where every westward route must pass
LandmarkThe ridge crest itself, visible from every part of the basin floor

Four places the first road could go

GroundFiscal readMobility readLivability read
Halstead ReachCheapest to build and service; forfeits fertile soil under everything you zone1.2 km to Dunthorpe; rail already alongsideFlat, unremarkable, upwind of nothing and downwind of nothing
Verrall Ridge shelf4.1 km of road including the climb; water pumped uphill; ore sterilised under any housingEvery trip runs through Thackray CutLong views, quiet air, the highest land-value ceiling on the map
Ombersley FlatsCheap ground, flood exposure, remote from the interchangeLongest haul to every outside connectionDownwind and downstream of the whole basin
Thackray CutNot a settlement; a piece of infrastructure with a priceThe only westward crossing of the ridgeNothing lives there

The value was in the ground first

The value of land is created by the community, not by the owner of it.

— the argument of Henry George, Progress and Poverty (1879)

  • Land value on this map rises around the things the district paid for collectively — the roads, the services, the parks — and not around the buildings sitting on it.
  • So a site decision is a revenue decision, and it is made in Week 1 whether or not it is noticed in Week 1.

Monday’s studio

  • Load the standard map. Do not regenerate it. Do not open the road tool.
  • Produce a one-page site report: the five McHarg layers, one screenshot each, and one sentence per layer on what it rules out.
  • Name your first settlement area and state the tradeoff you are making in the form used on Slide 14 — which metric you bought, which you paid with.
  • Save as <student ID>-w01 and put a copy somewhere that is not the machine you built it on.
  • Monday studio 13:00–16:00, Studio 2.14. Upload the untouched save and report by 21:00.
