This is because, although it is the busiest intersection by traffic count, the intersection <br />of Cleveland and County Road C is relatively far from the receptor locations established. <br /> <br />It can be seen from the above table that the CO standards are not projected to be exceeded at <br />any of the receptor locations assuming the project is developed as envisioned, and using the <br />information and methods outlined above, With the increase in traffic caused by the <br />additional 15,500 SF of office it is unlikely that the Co standards will be exceeded. Thus, it <br />is not anticipated that traffic improvements or other mitigation measures will be required to <br />address air quality issues associated with the proposed project. <br /> <br />Environmental Assessment Worksheet <br />Centre Pointe Business Park <br /> <br />Page 22 of 29 <br />
