Local Environmental Conditions
Located within the neighborhood, this area has hazel and willow crowd the water's edge, both classic sources of early allergenic pollen. Woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen; this sits just around the area. Nearby, in the vicinity, a stretch of mown parkland where turf and ornamental trees feed local grass and ragweed pollen.
Hazel and willow by the water are typically first out of the gate, usually the first pollen source active, peaking sometime in February or March. Woodland oak and birch pick up the pace next, through mid-to-late spring, usually hitting its highest point sometime between mid-April and mid-May. Late spring sees grass pollen build steadily toward a peak in June, followed by ragweed's own peak stretch from mid-August into October.

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. |
