Depth-Damage Estimate (HCAD Valuation)

Based on HCAD building value of $279,004 (2,999 sqft). Using U.S. Army Corps of Engineers depth-damage curves.

Depth-Damage Estimate (Neighborhood Comparison)

No neighborhood valuation estimate available. Building exists (2,999 sqft) but no comparable neighborhood data found.

Analysis Method

COG Bathtub Model

Raster-based flood inundation query

Flood Simulation

This simulation shows whether the property would flood based on a 5000-year flood event with 3m (9.84ft) water level. Use the interactive tool to explore different scenarios.

⚠️ Property Would Be Flooded

Flood Depth: 0.14 feet
Severity: Minor

Flood Risk Recommendations

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

This property is in a high-risk flood zone. Flood insurance is required for mortgages.
Consider flood mitigation measures like elevated utilities and flood vents.
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.
Simulation shows flooding at current water level - review property drainage and consider mitigation.

🏭 Part 2: Industrial Pollution Exposure

Property Pollution Ranking

High

Higher pollution than 87% 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)

3.81 million lbs

Extremely High

584.1x more than typical Houston property
≈ 191 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)

3.8 million lbs

Extremely High

787.2x 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)

15 thousand lbs

Extremely High

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.
