Ivix. Joe Offerman � �� � ���� 1669 N. Farm Road Long Lake, NIN 55350 � KE: F�ood 'L�vei of Pond Dear Mr. Offerman: We ha�ve reviewed the information which Rae 1'esek has subautted as `�vell as infom�atian collected by R.ick Lestina of our firm during his �cyisit to your property last week. The purpose of our review was to estim.a#e the 100-ye�x fiQod level in orde�' t0 52t minirrt� building elevations on the adjacent property. The pond has a very small tributary area and would be expected to h<<ve a �rery small flovd ir�crease. If we assume that the culvert is open and hinctior►al, the 14C�••year flood level would be 0.7 feet above the pipe i.r�vert or approximately 987.4. HowE:ver, it is becoming standard practice in Ilood control to avoid relying upon a single culvert, unless it is a major structvre with a defined m,aintenance program. When Mr. Lestina made his inspectian, #he culvert was compietely plugged with sedunent at the upstream end. (sroundwrai�r intlow and Iong-term runoff could raise the lewe� of the pond si�ificantly ab•��ve 9$7.4 i#the pipe is plugged. Iv�ar. Gaffron af the Cify�of Orono stated that he would pref�?I �'ldt �t2 ��nimt� ' builciing elevation be above the xunout level since standard mauttenar,r.e procedures cannot guarantee that the culvert wili always be kept opes�_ �ased on this inforniation, I would suggest that the m�T+�*rtuut buildut�; elevation be set tliree inches above the runout elevatioa over �.ong Lake Road _ Based vn the topagraphic map this wouid be Elevation 9915. Beca�;�e of the accuracy iimitaiions af t�e topographic maps, I woul�i kca�� the builder refere3nc�+� the actual minim�ctrn � building elevation to.the ov�flow point of the raad whert cor�s#zuctioii begins. I shouid alsa note th.at a second overflow raute exis#s from the pond to the south, ts�ward the cul-de-sac of ; Farm Road.' Lf the Long Lake Road overflow is too high, the overt�ow to the south might be excavated ta produce another, lower overflow route. • -• � � I hope this inforsnation will help avoid any flood daaZage irt your nei€;iZborhood.

Oman: At Terry Dahlstrom s request I have reviewed Barr Engineering's study, dated July 10, 1995, of the small pond on this property. Mr. Dahlstrom has asked for alternatives to raising the proposed house to an elevation 3" above the low point of Long Lake Road or constructing an emergency overflow swale through the wooded site to the south. Both of these alternative would have negative impacts on the aesthetics of the home site. The issue appears to be two fold: what happens if the culvert under Long Lake Road becomes plugged and secondly, what happens if there is an event in excess of the 100 year event. It is my belief that both concerns can be addressed by the installation of a second culvert under Long Lake Road. The culvert should be set 4 inches higher than the existing culvert. This will help prevent sediment from collecting in the second pipe, since under typical situations it will remain dry. The culvert should be 18" in diameter to minimize the potential for clogging. The pipe material should be double wall corrugated polyethylene (MNDOT 3247), which provides a smooth inner wall, again to �in�m»e clogging. Polyethylene pipe should be bed in sand to prevent deforming the pipe. A bedding detail is attached. As an added precaution I recommend that the house be raised six inches. This will allow storage for a second 100 year rainEall event, in the event that both culverts are blocked. As a reEerence point a visable permanent marker (i.e. a boulder, fence post, etc.) should be placed near the proposed home by Mr. Dahlstrom s surveyor at the outlet elevation of the pond (986.�. Standing water above the marker could alert the homeowner to a blocked culvert. Within a day of most rainfall events the water level should return to the outlet elevation If you have any questions feel free to contact me.

James F.Engelhard[ Mr. Lyle Oman, Building Official City of Orono Post Office Box 66 Crystal Bay, Minnesota 55323 Re: 1669 North Farm Rd. File No. 139-Gen Dear Lyle, We have reviewed the proposal to install a second culvert under Long Lake Road and excavate the ditch along County Road 6 to provide an adequate outlet for the existing wetland on Lot 8, Block 1, The Farm at Long Lake. The initial calculations done by Mr. Nels P. Nelson, BARR Engineering Company and the recent letter by Stephen M. Johnston, Landform Engineering Company appear acceptable from an engineering standpoint. The house walkout elevation should be set no lower than elevation 988.5, as determined by Landform Engineering Company. This will provide approximately one foot of freeboard above the calculated 100-year flood clevation. The l�omeowner should be advised that one foot of freeboard may not be adequate protection from flooding during a larger frequency storm event. Silt fence should be installed at the downstream limits of the proposed grading prior to commencing with the work. Long Lake Boulevard must be repaired to its original cross-section or to a minimum of six inchcs of Class 5 aggregate base and 4.5 inches of bituminous mixture ('I�pc 41)whichevcr is greater. Bituminous mixtures must be placed in lifts not exceeding three inches in thickness. All backfill below the Class 5 aggregate must be granular borrow material mecting MnDOT Specification No. 3149. Access along Long Lake Boulevard must be maintained at all times, keeping one lane of traffic op�n. Traffic control must be installed and maintained in accordance with the MMUTCD. The City should be notified for inspection at least 48 hours prior to removing the surface of Long Lake Boulevard. We would recommend a $10,000 letter of credit be provided to the City to insure that the work is done satisfactorily. Please contact me at this office if you have any questions regarding this matter.
