Summary
Environmental snapshot for Houston-The Woodlands-Sugar Land — 2 of 10 blocks populated (8 pending upstream migration).
- Coastal metro — tide gauge data available via the optional Coastal Conditions block.
- CBSA population ≈ 7,340,000 (2022).
- Climate zone: Humid subtropical (Cfa).
- Report is statically generated — see Methodology block for trust-tag vocabulary and source list.
Air Quality
Ambient air quality in the Houston-The Woodlands-Sugar Land metro is tracked by EPA AirNow (current AQI) and regulated facility compliance via EPA ECHO. Step 5 scaffolding — live AirNow/ECHO data pending v2 connector migration.
No metric values available yet.
- AirNow reporting area may differ from the CBSA boundary — regional readings approximate metro conditions.
- ECHO compliance status is not a direct measure of local exposure (compliance ≠ exposure).
Climate & Heat
Local climate baseline for Houston-The Woodlands-Sugar Land is drawn from the NOAA 1991-2020 climate normals at the primary city station. Heat-day counts (days ≥ 90°F / ≥ 95°F) are derived from daily summaries. Step 5 scaffolding — ClimateNormals v2 connector pending.
No metric values available yet.
- Köppen climate zone: Humid subtropical (Cfa).
- Reference station: Houston Hobby AP (USW00012918).
Disaster Exposure
Federal disaster declarations affecting Harris County over the past decade are catalogued by OpenFEMA. The summary block reports counts by incident type; the detailed event-level history appears in the optional Disaster History block when ≥1 declaration is present.
No metric values available yet.
- Declarations reflect federal response requests, not the full inventory of hazard events.
Drinking Water & Surface Quality
Public water system compliance in Houston-The Woodlands-Sugar Land is tracked by EPA SDWIS (violations and health-based actions). Ambient surface water quality samples come from the USGS/EPA Water Quality Portal (WQP). Step 5 scaffolding.
No metric values available yet.
- WQP samples are discrete observations — date coverage varies by parameter and station.
- SDWIS violation counts do not include every small system on identical cadence; reporting latency applies.
Industrial & Emissions
Reporting facilities in and around Houston-The Woodlands-Sugar Land disclose toxic chemical releases to the EPA Toxics Release Inventory (TRI) and greenhouse-gas emissions to the GHGRP programme. Both inventories lag by roughly one reporting year.
No metric values available yet.
- TRI covers threshold facilities only — small emitters are not represented.
- GHGRP applies to facilities emitting ≥25,000 metric tons CO₂e.
Contaminated Sites & Cleanup
Federal contaminated-site programmes tracked in Harris County include Superfund NPL (National Priorities List), the EPA Brownfields ACRES database, and RCRA hazardous-waste TSDFs.
No metric values available yet.
- Site status reflects programme listings — active remediation status and on-site exposure pathways are case-specific.
Population Exposure & Environmental Justice
Roughly 7,340,000 residents live in the Houston-The Woodlands-Sugar Land CBSA. Full environmental-justice indicators (EJSCREEN percentile exposure + demographic overlap) are a Step-6 deliverable — this Step 5 block reports CBSA-level population only.
No metric values available yet.
- CBSA boundaries approximate commuting patterns, not exposure watersheds. Block-group EJ analysis requires a different geographic unit.
Coastal Conditions
Tide gauge observations and mean sea-level trends for Houston-The Woodlands-Sugar Land are drawn from NOAA CO-OPS. Step 5 scaffolding — CO-OPS v2 connector pending.
No metric values available yet.
- Station coverage is non-uniform — the nearest gauge may be outside the CBSA boundary.
Methodology & Data Trust
This report is assembled at build time from multiple federal environmental data programmes. Each block above carries its own `trustTag` indicating how direct the underlying signal is — `observed` (direct measurement), `near-real-time` (satellite or sensor feeds with hours-to-day latency), `forecast` (modelled projections), `compliance` (regulatory self-reporting), and `derived` (composite or estimated quantities). Missing data is reported explicitly, never filled by imputation.
Trust-tag vocabulary
- 🟢observed
- Direct instrument measurement (ground station, gauge, or in-situ sensor).
- 🟡near-real-time
- Satellite or sensor feeds processed within hours to a day of observation.
- 🟠forecast
- Modelled projection (e.g. CAMS, GFS, ERA5 hindcast).
- 🔵derived
- Computed or estimated quantity composed from one or more observations.
- 🟣compliance
- Self-reported regulatory disclosure (e.g. EPA ECHO, TRI, GHGRP).
| Metric | Value | Trust |
|---|---|---|
| Core blocks present | 7blocks | 🔵derived |
| Block trust-tag mix | 6 × derived, 1 × observed | 🔵derived |
- No composite environmental score is computed. Each indicator is reported on its own axis with its source programme named.
