1.4 Soils, Slopes, Vegetation, and Current Drainage Patterns

Soil type(s): Fill soils at the site generally consisted of sand and gravel with trace amounts of clay, silt, wood, brick, and crushed stone. Beneath the rubble of the old building basement level fill soils were found to extend to depths of about 1 ½ to 3 feet below existing grades. Fill amounts found in the borings completed within the parking lot or near the grade of the previous buildings first floor slab level were generally greater with depths of about 8 ½ to 13 ½ feet. On the east corner of the site fill materials were encountered, which extended to about 20 feet below grade. Native soils below the fill soils predominately consisted of fine to coarse sand with gravel or sandy gravel and extended to the boring termination depths of about 25 feet or to bedrock refusal materials. Elevations of the borings ranged from about 634 feet to 642 feet in reference to the benchmark at 647. About 3 to 4 inches of asphalt pavement was encountered at the surface of the existing parking lot and 4 inches of concrete slab was also encountered near Hoyt Place. Slopes (describe current slopes and note any changes due to grading or fill activities): The slopes range from 5.20% - 8.90%. Drainage Patterns (describe current drainage patterns and note any changes dues to grading or fill activities): The existing drainage pattern drains from northwest of the site to southeast of the site towards Fox River.

SECTION 4: SELECTING POST-CONSTRUCTION BMPs

BMP Description: Permeable Paving Installation Schedule: April 2010 Maintenance and Inspection:

It is recommended that permeable interlocking concrete pavements be inspected on an annual basis, preferably in spring after a major rain storm to verify that the stormwater is infiltrating into the system. Areas that have pooled water standing on the surface need to be addressed through remedial maintenance as opposed to routine maintenance. A monitoring well may be installed with the system in some instances and will provide for access to the bottom of the system for observation for rate of exfiltration. The monitoring well also could be used to take water samples to permit runoff quality analysis.
