ENVIRONMENTAL BOARD MEETING NOVEMBER 28, 2001 111 6. DISCUSSION ITEMS • • A. Clearwater Creek 3rd Addition — This item was discussed later in the meeting. B. Surface Water Management Plan Discussion — Powell distributed and referred to the Infiltration Checklist from the Rice Creek Watershed District, and a memo from Richard Thompson. He stated that they were in the process of assembling information so that they did not have to refer to the project files later. The Infiltration Checklist is distributed to developers to be completed and address all points on the checklist. Any inconsistencies between the checklist and present City policy must be reconciled. There were times that the Watershed had a requirement, but the City removed it. He noted an example of that was the Watershed District required raised islands in a cul -de -sac, while the City needed the streets to accommodate emergency vehicles.

The City ~ quired natural vegetation as stated in the Act; however, no covenants were required as in the Watershed District. Donlin inquired about the needs for fire, snow removal and storage. Powell answered that the issue could be resolved with a raised island. However, residents usually were concerned about the need to see children playing in the street, but he assured the Board that it was not insurmountable with low plants. If snow would be piled on the islands the plants would be crushed. Powell identified in the area of vegetated swales, and noted that education was the biggest obstacle. In the past the City did not allow swales, and developers wanted a catch basin. The major issue was the prevention of compaction, so either the developer could not compact the soil, or must loosen the soil if compaction occurred. The need for imported soils presents another concern because the
