The proposed Landscape Plan does not include any trees along the west side <br />of the new front walk, the new islands east of the gymnasium, along the <br />walk north of the new event parking lot or around the new drainage pond. <br />Additional shade trees should be planted 50 feet apart along the west side of <br />the new walk, In the pedestrian and parking islands, and along the north side <br />of the event lot. Groupings of evergreen trees should also be planted in the <br />area to the northwest and west of the event lot, and a few groups or <br />clusters of overstory or understory trees should be located around the new <br />drainage basin. <br />plant Palette <br />The proposed plant palette Is very utilitarian and practical. However, it does not <br />Include trees with good fall color or good winter interest. We recommend expanding <br />the plant schedule to include one or more overstory trees with fall color (IE. Red or <br />Autumn Blaze Maple) and two additional understory trees with seasonal interest (IE. <br />Ginnala Maple, Shadblow Serviceberry, Pagoda Dogwood). <br />The Landscape Plan also needs to clarify the areas to be seeded or sodded. <br />Phasing <br />Large public facilities such as this should include the preparation and approval of a <br />Landscape Master Plan that will be phased over several years. The contract <br />documents could include additional plantings as an alternate to provide a means <br />documenting the approved plantings and adjusting to the budget requirements. The <br />planting of additional trees will improve both the aesthetics and function of the <br />campus. We recommend that additional or phased additional plantings be required <br />as a condition of approval. <br />FROSION CONTROL <br />The District must ensure that erosion control be provided, monitored and <br />maintained wherever needed until the vegetative cover in the disturbed areas has <br />been fully and finally restored. Erosion control may be needed along the woods to <br />the northeast of the created wetland depending on the extent of the grading and <br />disturbed area. <br />Erosion control must be also placed to protect the required 26 feet wide buffer zone <br />surrounding the wetlands designated to remain. The grading adjacent to wetlands <br />8 and 6 should be revised to avoid encroaching on this buffer zone. <br />-4-
