Local Environmental Conditions
Nearby, near this part of town, the waterside growth here is largely hazel and willow, both efficient wind-pollen dispersers. Oak and birch dominating the treeline, both heavy contributors to the spring pollen load, within the neighborhood. This park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load; this sits nearby.
Hazel and willow along the water get the season underway before other species, getting an early start, typically cresting between February and March. Further into spring, the area's oak and birch stands drive the pollen count, typically the year's sharpest tree-pollen spell, centered on April and May. Grass pollen takes over next, building to a peak around June, before ragweed takes over as the dominant allergen 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. |
