Local Environmental Conditions
Located within the neighborhood, this area has the riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze. Nearby, nearby, a stand of oak and birch, the latter ranked among the region's most potent tree allergens. This park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load, not far from here.
The bank's hazel and willow kick off the pollen season ahead of the rest, leading off the pollen calendar, with a peak generally falling in late winter. The area's oak and birch trees pollinate through mid-to-late spring, topping out in the April-to-May stretch. Through late spring, grass pollen climbs steadily toward its June peak, 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. |
