Sensitivity (±20% per driver)
Order-of-magnitude annualized value derived from peer-reviewed coefficients (WHO HEAT, EEA shadow price, ITF/UITP, Litman). Bands reflect coefficient uncertainty, not site-specific calibration. Replace coefficients with local elasticities for client-grade work.
Mediterranean core under heavy UHI load — +3.2°C above the regional baseline, ~47 tropical nights/yr; mitigation should rank above further densification.
v0 estimator pending Copernicus Sentinel-3 SLSTR LST integration. Anchored on EEA 2022 Urban Heat Report zone baselines and WHO Europe heat-attributable mortality coefficients. Replace with site-specific LST grid for client-grade work.
Mediterranean core well above the WHO 2021 PM2.5 guideline — annual mean ~20.1 µg/m³ (+15.1 over guideline); air-quality interventions belong in the top tier of the action plan.
v0 estimator — no OpenAQ v3 stations in radius. Anchored on EEA 2023 Air Quality in Europe annual-mean backgrounds and WHO 2021 global Air Quality Guidelines. Replace with site-specific monitor data for client-grade work.
Mediterranean catchment already at or below the EU SUMP 40% car target (~28%). Mobility is not the binding constraint — preserve and extend the existing modal mix.
v0 estimator pending Strava Metro tile pull + GTFS frequency parse cached against the audit isochrone (Sprint 32.1). Anchored on EU SUMP 2019 modal targets, INRIX 2024 Global Traffic Scorecard congestion costs and ITF/UITP per-trip reference values. Replace with site-specific household travel survey for client-grade work.
Mediterranean streetscape reads as exemplary (composite 4.1/5) — walkability, canopy and façade activation reinforce each other; preserve and extend the existing fabric.
v0 estimator pending Mapillary v4 image-grid pull + Gemini 2.5 Flash vision classification over a sampled 50-image grid per AOI (Sprint 33.1). Anchored on Jacobs (1961), Gehl (2010) and Ewing & Handy (2009) perceptual urban-design qualities. Replace with site-walked audit for client-grade work.
Mixed Mediterranean pluvial exposure (~€57/resident/yr at 29% AEP) — moderate flood-driver leaves headroom for green-infrastructure retrofits and ground-floor adaptation.
v0 estimator pending Copernicus EMS pluvial-hazard tile pull + JRC LISFLOOD output cached against the audit isochrone (Sprint 35.1). Anchored on EEA 2024 Floods Directive reporting cycle, JRC 2020 pluvial-hazard atlas and Munich Re NatCat 2023 European urban-flood loss data. Replace with site-specific drainage modelling (SWMM, InfoWorks ICM) for client-grade work.
Lden 67 dB is ~14 dB over the WHO 2018 guideline — chronic-noise exposed. Low-noise asphalt, 30 km/h zones, double-glazing retrofits and street-tree barriers are top-tier mitigations.

Each driver follows the same clamp(raw, 0, 1) × max_dB envelope (CNOSSOS-EU 2012). When the pre-clamp ratio > 1 the lift is capped at its saturation; when ≤ 0 it is zeroed. Apply the same trace to reproduce Lden by hand.
v0 estimator — EEA NOISE-viewer sample unavailable for this catchment (likely outside an END-reported agglomeration). Anchored on WHO 2018 Environmental Noise Guidelines for the European Region, EEA 2020 'Environmental noise in Europe' synthesis and CNOSSOS-EU (JRC 2012) emission + propagation curves. Replace with site-specific acoustic measurement (ISO 1996-2) for client-grade work.
Tenants spend ~61% of income on housing — ~21pp over the Eurostat 40% overburden line. Rent caps, inclusionary zoning bands, social-housing pipeline acceleration and renovation-tax-credit re-targeting are top-tier mitigations.
v0 estimator pending a Eurostat SILC NUTS-3 overburden pull cross-checked against the OECD Housing Affordability Database 2024 deciles, cached against the audit catchment (Sprint 37.1). Anchored on Eurostat SILC 2024 'Housing cost overburden rate' (ilc_lvho07a), JRC 2022 'Affordable Housing in Europe' synthesis and OECD 2023 'Housing Taxation in OECD Countries'. Replace with site-specific rent-roll + income microdata for client-grade work.
Coefficients sourced from NACTO Urban & Transit Street Design Guides, ITDP BRT Standard, World Bank cycling benchmark, C40 Knowledge Hub and EU EIT Urban Mobility. Uplift band inherits Value-at-Stake driver coefficients (±20%). Replace CapEx with site-specific quotes for tendering.
