• <br />• <br />• <br />AGENDA ITEM 1 - 03 <br />STAFF ORIGINATOR: Marty Asleson <br />DATE: Summit Fire Protection <br />TOPIC: Site Plan and Minor Subdivision Application Review <br />A ," <br />eiJc(u(ai ) <br />BACKGROUND: The site plan for this area was reviewed at the June 28, 2000 <br />Environmental Board Meeting in conjunction with the Marmon Keystone project. <br />Marmon Keystone is an approved project that is currently under construction and <br />is located immediately to the East of the Summit Fire site proposal. Summit Fire <br />is located on what is platted as parcel F. <br />At the June 28,2000 meeting, existing excavated areas that could serve as <br />infiltration ponds were discussed. Pond 1 is the pond that is on the SW corner of <br />this commercial development area and in the SW corner of this property. <br />Virtually all of the surface water drainage for the Summit site will go to this pond <br />#1. This is exactly what was discussed on June 28th. Project engineer John <br />Johnson has created additional swails to slow and infiltrate the water from this <br />site. Pond 1 will also take the water drainage from 2 acres on the parcel to the <br />north. <br />As noted from the submitted infiltration checklist sheet, water from roofs will be directed <br />into storm pipes feeding directly into two constructed infiltration basins. Curb and one <br />catch basin in grass area will be directed to infiltration basins. <br />Soil compaction is indicated to be 95% (engineering standard for settlement <br />assurances). I have talked to John Johnson about this and John will write a spec for the <br />vegetation growth areas that would reflect the soils are no higher in density than 1.7 <br />grams per cubic centimeter. This is the limiting soil bulk density for plant growth in fine <br />sand soils. <br />The landscape plan reflects the standard that seems to be acceptable in the business <br />district. That is, irrigated turf in the front and native materials in the drainage areas. We <br />have in the past asked for a maintenance contract to be signed with a company <br />knowledgeable in native plant culture, for the areas that have these native plant areas. <br />
