SERVICES; 3-16-98 2: 57PM (612) 338-8971-; 6124730510:# 4/ 4 <br />March l 6, 1998 <br />Page 3 <br />Additionai Considex-atioas <br />In addition. to the dep;r;css,ion volwu~ and schematic discussed alxrve, the following <br />recommendations should be considcr~d in constructing th~ depression and the final landscapin.g <br />of the affected areas: <br />► To accommodate city drainage off'Bahn's Point 'R..ond, tho landscaping should incolp()rate <br />pfa.nt rna1:e-rials and groundcover resistant to :runoff velocitiM and volumes. Anothei: option <br />would be placement of a rock s~le from the road to the low point n~ the lake or to the <br />lake, <br />► The existing drainage patterns direct r1.ID.o:ff into the low area on the property to the south. <br />Final site grading, depression construction~ and other drdlnage efforts sboutd be coordinated <br />with the adjacent p:roperty owner to continue the current drainage pattern to ihe existing low <br />area or to com:;c;t it if it is viewed as a problem. Another option would be to redirect Bohti.'s <br />Point Road drainage onto your lot (by a swale or berm) and east into the lake bypassing the <br />low area on the adjai;e-nt lot. <br />► Proposed grading around th.e front of your home should direct runoff into the proposed <br />depression in ordtt for the plan to accomplish its objective. fo addition~ the depression should <br />only receive drainage from your lot and not from Bohn's Point Road since the mad drainage <br />would regularly fill and ovcrtop the depression. <br />► Although the <lt::preS!lion should not typically have standing water, the area will regularly <br />ri;x:eive runoff and may not re.main dty enough for healthy grass cover to be established. <br />Landscaping within the pond should be water ~olerant, or even a rock garden with a pea <br />gravel base tQ encouxage infiltration. <br />► 1be final depression design $hOUld be coordinated with landscaping efforts to m,itisfy <br />drainage volumes, runoff patterns;r aud aesthetic desires. <br />► The slopes off the southern !Iida of the pxopos.ed house may become steeper 'than des:irnble <br />with the proposed depression and drainage swale. It may be necessary to install a buried pipe <br />in this area or construct a small retaining wall to convey drainage past the home. <br />If you have any questions abo·o.t this memorandum or need additio;o.al assistance, please call me <br />at476-6010.
