2516 Rid�e L�ne I?ounds View, 1.11nnesota Sentember 7, 1978 S' T:avor John Pickar !,Q �i9I� L:ounds View Citg Hall MDy'� ��(�bL 2401 Highway�l0� 4lev� Brighton, hiinnesota Dear htayor Pickar: In response to n� a�peariag bePore the Cit� Council on Septemoer 5� 1978, srhere I brie£ly talked about tt�y desire to remove sone silt from ou"r pond, the follorring in!'ormation is hereoy subnitted per your request. I am writing this letter as President o_° tkie �Ihite Oak Homeowners Association'vrho omn the oond south of Rid�e Lane and East o° Long Leke Road. The Problem: Vde have a 3z acre reclained pond which is ringed bg 29 homea and a city well house. 7dhen the pond r+as reclaimed� the peat was taken from the nond�and piled uo on the shore ar.d prior to the time it could be hauled�away, a quantity o£ it waened back into the pond vrhere it remains to date. The nezt has not creeted too la^ge a problem foa us a� far as the water quality is concerned, but it has covered a mafor portion oP the sand botton o£ t'�e lake� and �vnen stired up� dnes make tha riater less clean. 'a'!a recently ha3 a consultant look at ocr pond as we had §ome concern abo�t needing to do sor.:e maintene.nce on the wect shora line. He told us aE that tine tnzt our mejor concern should be the removal oP the silt. Aiter exanin_ng a nunber o° possiSle solu�ions to removing this silt, we h�ve decided the best solution r•iould be to use a �uction dredge and vaccuun the 6ottom o: the pond, The exact amount of silt to be removed can onlg be guessed at, as there ar= a number oP factors Sncluding the ease riith vi::ich it is suckc-d out. The Roto-Rooter com�anq has experience with this type of pumnin; an8 has indicated to us ttiat they cokln easily do this project with a n+_nimun of problems to the are� and the hones around the oond. The Pr000sal: As the dumpin; oP the vra+er. and silt is the najor problem' in s suction dred�in� operation, vie are reauastin.� yernission to use the vacunt lots ut the northerst corner of Ridge Lar.e and Long Lake Road. S�ie would nake a dike o^ straw bails starting about 25 feet v�r.st of the east edge oS t'riese lots a::d have the diked in area, s large oval�' covering the area from the startir.� noint over towards 9,ong Lake Road, The silt anc water would be punned into tnis oval wh=re the sclids would settle out and the viater }voud run throu,;h the'strc�w, end into the storm sc�rier outlet in the corner of the vacant lots. The stravi would be aeting ss a filter� leavin� sll of t::e solids within tne CCA1, After the water has bee,n removed fram tne silt, we rrill either remove the silt from the land. or leave it the^e ^or the City io use as fill for thia ares which we understand is to be filled Por e park, 71e understand from the Roto-Rooter representative ti;at tha silt ce.n be sor�es�hat piled up when it ia puMned in this process. The uunoin,r, procFSS might take un to three days, `:ut proba'�ly no lor.;;er.
