Although I do <br />not have the benefit of walking an site, from a distance the plan appears <br />incomplete. Specifically I would like your staff to Snspect the site and <br />respond to the following list o£ concerns at their earliest convenience. <br />~A: Has tree planting been completed to the prescribed density and species <br />~~ at corrective plan areas one through four? <br />B: Has tree planting Started at areas five through seven, and i£ so, to the <br />prescribed density and species? ~"''° <br />G: Have the trees been tagged for future accounting at anniversary dates? <br />?ir. Heifner stated in our previous hearing than by tagging and counting, <br />replanting for demise, the establishment criteria would eventually be roes. <br />D: Has reseeding occurred at areas two, three and four? If so, why does <br />erosion still appear prevalent in these areas? If we are expecting a <br />future germination date, whac is that date? <br />E~ Why is an eroded area still highly visible and without improvement ?~1~ <br />- ~ feet down the road from area four? This area appears to be 80 feet Sn <br />length and 40 feet in width from the road shoulder. 1 <br />F: Silt fences in area one appear in disarray. Should they not be rebuild? <br />G: Would it appear prudent to add silt fences or blankets to steep and <br />highly eroded areas at locations two and three? <br />This is a brief checklist after a cursory look from a distance. This list <br />does not address other corrective plan items such as the culverts and the <br />Williams Canyon corrective work. I would be appreciative of receivin6; your <br />staff's report, a reply to the Stems above, and any additional report items <br />your staff could review to verify we are reaching are mutual goal. TF~ank you, <br />in advance, for these efforts. <br /> <br />Sincerely, <br />~~~ <br />~+regory I.
