Home My WebLink Aboutseptic info � . ! s • i I Orono residents on mound type septic systems m: Willie Gibbs, ISTS Manager ate: May 10,2006 e; Landscaping Do's and Don'ts for Mound Systems, Quick Reminder o plant and maintain a full cover of grass and keep mowed to a normal height, this grass cover aids the evaporation of large amounts of effluent(the liquid left after the "other' stuff has been removed) the summer time and allows the mound system to hefp breakdown nitrogeFl in the effluent. o water the grass over the mound in extreme dry conditions, sparingiy. o avoid unnecessary foot t�affic over the mound, maw it and stay off of it. This is especially true in the inter time. Even human foot traffic can cause frost to penetrate the mound resulting in potential eezing problems. o inspect your mound system annually for winter kill, (reseed if necessary) animal damage, urrowing)or signs of potential failure. o not plant trees or shrubs on the mound system, smaller trees and shrubs may be ptanted at the dges. Remember,that sunshine is the key to a healthy mound system. o ask questions, if you have any concerns or questions concerning your mound system lease feel free to call me, I can be reached at 952-249-4626. , 1 � ,I �� CITY OF ORONO � � Municipal Offices � �, 3treet Address Mailing Address: '� G'�' 2750 Kelley Parkway P.O.Box 66 '�.,9 ,�� Orono,MN 55356 Crystal Bay,MN 55323-0066 kEsHo To: The Current Owner of Address 3120 SUSSEX RD �it Ordinance requires that onsite sewage treatment systems in Orono be inspected on a peri ic basis.

Gaffron, Asst Planning & Zoning Administrator ate: August 22, 1989 ubj�ect: Preliminary Plat of Fox Bend - Septic System Testing Septic system site evaluations for this 17-lot subdivision a�een submitted. Additionally, a topographical survey of the roperty containing a plot of the drainfield sites has been ubmitted ��9� I�make the following comments regarding each proposed lot: Lot 1, Block l. Primary and alternate sites have been located. Both t�re sites require a mound system due to high seasonal water tables. Slopes range from 2$-6�. These two sites are about 50 ' from a proposed detention basin, but should not affect nor be affected by that basin. The sites should be totally fenced off with snow fencing before any road or detention basin construction takes place in the subdivision. Lot 2, Block 1. Primary and alternate sites have been located, and both sites have soil and water table conditions to allow for a trench drainfield system. With the proposed house site at the south end of the lot, there should be no problem preserving these sites. Again, the drainfield area should be fenced off to keep all traffic away during road and de�ention basin construction. , ....._..._,�.�..��.. _�..�_. , .. _... .. .._.. ,�,. Lot 3 , Block l. Again, primary and alternate drainfield � ,sites are suitable for trench systems. The two sites are at the rear of the lot. With the most likely house site near the front of the lot , these sites appear to be very suitable. ,, _ _ .._ � ILot 4, Block 1. Primary and alternate drainfield sites are �located on the knob at the southwest corner of the property. Both sites require mound systems. With the house site suited for a walk-out to the northeast, a driveway would likely be centered on the lot east of the drainfield sites. Slopes are in the range of 3�, and not accurately ref lected by the topographic map. It is critical to totally enclose these sites with snow fence prior to any road construction work, since the sites are very close to the road. Also, road grades and cuts should be reviewed to verify that the roadwork will not cut into site #2. Lot 5, Block 1. Primary and alternate drainfield sites are located to the rear of the property on slopes of 0-2$. Both sites require a mound system. With the probable house centrally located o� the lot, these sites appear ery suitable. , � xe 'minary Plat of Fox Bend - Septic System Testing pg t 22, 1989 �g 2 of 4 � Lot 6, Block 1. The drainfield sites are near the rear property line, and not likely to be affected by construction traffic. These sites are located about 70' back from the travel led portion of Luce Line Trail, and should have no affect nor be affected by the trail. Slopes are virtually flat. Again, the likely house location would be in the center of the lot. Depending on final house location, additional sites might be located on this property. Lot 1, Block 2. Primary and alternate drainfield sites have been located at the north end of the lot, adjacent to the proposed road connection to Leaf Street. These sites both require mound systems, and this is perhaps the most critical lot of this subdivision since drainfield sites are uphill from the proposed house location and surrounded on two sides by proposed road construction. These sites must be surrounded by snow fence to avoid any construction traffic. The building envelope is large enough that a house can be constructed leaving approximately 50-60' or more setback from the drainfield sites. I would further recommend that no driveways or other grading be constructed within 30' of the toe of the mound sites. Again, the contour lines shown on the topographic survey do not quite jive with elevations found in the field. Lot 2, Block 2. Primary and alternate drainfield sites are located at the southeast corner of the property near Fox Street. The house site would be located north of the pond area. The two drainfield sites tested must be preserved, ' since they are the only two available sites on the property, both requiring mounds. From a technical standpoint, location of drainfield systems as much as 300-350' away from the house should not cause any problems. Lot 3, Block 2. Both primary and alternate drainfield sites were located on the property. The primary site would be . suitable for a trench-type system. The alternate site would require a mound. Both sites are located in the wooded area of the lot. Lot 4, Block 2. Both primary and alternate drainfield sites have been located. Those sites are generally parallel with the proposed road and near the north lot line. These sites definitely need to be snow fenced totally in order to preserve them during road construction. I� � t. i P �1' inary Plat of Fox Bend - Septic System Testing A gu 22, 1989 P ge of 4 ot 5, Block 2. Primary and alternate sites are located ' bout a third of the way back into the lot off the road. 'ust above the woods. While additional sites probably could e located in the woods, the sites leave a relatively small uilding envelope near the road. Again, the sites need to e snow fenced to keep construction traffic off of them. oth sites require mounds. ot 6, Block 2. Primary and alternate sites, both being ound systems, are located near the north end of the roperty near the road. Again, topographic contours vary lightly from those shown on the survey. Slopes range from -6$. These sites force the house I.ocation to be more entrally located on the property. The sites need to be now fenced to avoid traffic during road construction. ot 7, Block 2. Both primary and alternate drainfield sites re located near the north end of this lot. Both sites equire mound systems. The sites allow for great lexibility in house location. ot 1, Block 3. Primary and alternate drainfield sites, oth being mound systems, have been located on the property. ouse location would be relatively near the cul-de-sac. The rimary site somewhat limits the potential house locations. ot 2, Block 3. Primary and alternate drainfield sites, oth being mounds, are located near the westerly corner of his property. These sites definitely need to be fenced off � uring road construction, since they are in a prime "short- ut". area. ot 3, Block 3. Both primary and alternate sites are ocated at the extreme east end of the property, leaving reat f lexibility in house placement. These sites are not ' ikely to be disturbed during construction of roadways. - ot 4, Block 3. The two drainfield sites are centrally ocated on the property, having some significant effect on ouse placement. The site evaluator anticipated the xisting house would be removed, with a newer house placed o the northeast corner of the lot. House placement will ave to take into account the drainfield sites. Both sites equire a mound. , �e minary Plat of Fox Bend - Septic System Testing u t 22, 1989 �g 4 of 4 i al Cc�nents - Each proposed lot appears to have suitable primary and �t rnate drainfield sites. On some lots, the primary and lt nate sites shown are the onl possible sites available. On th lots, it is likely that additional testing could find a �lm r of potential sites, al lowing additional f lexibility in qu placement. In each case, drainfield sites have been designed to meet he inimum 20' setback from property lines, and 75' setbacks ro designated wetlands. � On the majority of lots, estreme cantion must be taken ur ' g construction of improvements to the property. Road on ruction will take place within 50' of tested drainfield it on at least 6 of 17 lots, and on 2 lots the sites are e41 ively near the area proposed to be graded to provide a �'te tion basin. I would recommend that each lot have drainfield ijte protected by snow fence total ly surrounding the drainfield it at a distance 20' from the boundaries of each drainfield ys m. Additionally, when road construction plans are ub tted, I would like to review them to determine where road ut ould have a potential impact on drainfield sites. Out of 34 drainfield sites tested, 29 require mound systems d would allow a trench-type system. Each lot has primary and lt i nate sites designated. It would not be surprising if as ny s 20$ of the sites ultimately will have to be re-tested due o t e buyer's preference for house sites near or conflicting '�h rainfields. Some lots are extremely limited for potential �i field sites, others provide a degree of f Iexibility in house p �c ent. , iven the above facts, concerns, and constraints, I would r �o end approval of the subdivision as proposed. Accompanying t is emo is a topographic survey of the preliminary plat showing p te tial house Iocations and locations of both primary and a te ate drainfield sites. �r � :1 i' I � ♦ -� ..�''" � ... `� F / , µ.. , � : � � � �,`'�S';'�� ..,; I ,�'� fOy /',. .�:;: �: �� oya � � _ _ _ � ; i��r '�� =`'�" � � — � � ��!� o ' �. � ' d�' ' I''' .s-�,- � ��° ,.: � � , � � , ��; - 0� ., , '. � ,�� i� �, a! � ��_ `� � v� �� ,i , a�`y �� N , �- ' ' � ;, x � ,� '� °� 1Q� ��'> �.- � �� ' �k� � �° '� ,�i � �� /' ��,~ +~� � �I, i Y } � �.� �C (� � � �'� i��„r If .,�� ^ ' / � �l� � C � �� ii 1�+ ♦ �i � ' •, � t.�� `� 1' ; • � � - � - �1. �� , ,, �„ el"0�:�� ;Ii � ` / ..� � �' ` � � �, i: �� ,\ h�?; �� • 'f �.d� � \ ii • / � � �� 1�'�� 1'� q ♦ , \ � � � �� i �� ' � � � � � �� I � ` ' . ��1 � '�' � � � � � � �� •� 1I#'� '� f w; r � 'I� � � 0 � , � ','� P'k r / /� �jj4 +i t , ,P � , ,_ � `�J � �, � � �- r �;'�a. � ' � � � ` _ ,,[ � ► 1 1\ � � p F � c � i i f � � � � �� .,t � � ��'' + , � ' . .
