Local Environmental Conditions
This area, within the neighborhood's edge, has hazel and willow cluster near the water, an early and reliable source of allergenic pollen. Located within the neighborhood, this area has a wooded area built around oak and birch, both contributing heavily to the region's spring pollen totals. Local microclimate and soil conditions can push these figures slightly higher or lower.
Along the waterway, hazel and willow release pollen first, starting well before the main spring rush, topping out around March. The area's oak and birch trees pollinate through mid-to-late spring, building to its sharpest point across April and May. Moving into early summer, grass pollen climbs to its seasonal high in June, handing off to ragweed, which peaks from mid-August through October.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
