Data-driven insights for local properties

📊 Environmental Assessment Report

This comprehensive report analyzes both flood risk and industrial pollution exposure for this property. The assessment combines multiple data sources including USGS elevation, FEMA flood zones, historical storm modeling, and EPA Toxic Release Inventory records.

🌊 Part 1: Flood Risk Analysis

Property Overview

This section shows the fundamental characteristics of the property, including its elevation above sea level, FEMA flood zone designation, and our calculated overall flood risk rating based on historical data and topographic analysis.

Flood Risk Recommendations

Based on the property's flood risk profile, here are specific action items to consider.

  • FEMA Zone X (minimal hazard) - flood insurance available at preferred rates.
  • Review the interactive flood simulator to understand how different rainfall events could affect this property.
  • Contact Harris County Flood Control District (HCFCD) for drainage projects and flood information.

🏭 Part 2: Industrial Pollution Exposure

Property Pollution Ranking
Moderate
Higher pollution than 73% of Houston homes
This ranking compares pollution levels within 2 miles of this property against 10,000 randomly sampled Houston metro properties. Lower percentiles indicate higher pollution exposure.
Industrial Pollution Nearby (Last 10 Years)
340 thousand lbs
Very High
52.1x more than typical Houston property
≈ 17 dump trucks of chemicals within 2 miles
Total chemical releases from all industrial facilities within a 2-mile radius over the past decade (2014–2024). Data from EPA's Toxic Release Inventory tracking air, water, and land discharges.
💨 Air Pollution (Last 10 Years)
332 thousand lbs
Very High
68.9x more than typical Houston property
Chemicals released into the air from nearby facilities over 10 years. Includes both fugitive emissions (leaks, evaporation) and stack emissions (smokestacks, vents). May affect local air quality.
💧 Water Pollution (Last 10 Years)
8 thousand lbs
Very High
Most Houston properties have none nearby
Chemical discharges to surface water (bayous, streams, drainage) from industrial facilities within 2 miles over the past decade. May impact local waterways and drainage systems.

❤️ Why It Matters

High chemical activity nearby can indicate industrial zones, truck traffic, or potential odor and noise issues. These factors may affect air quality, long-term property desirability, and neighborhood character. This data helps you understand the industrial footprint around your property.
