I believe the attached plan addresses all of your comments(also see below). How many plans do you want submitted? My understanding is that the fee is$55 for a repair. Are there any other requirements for the Variance Requests? � � Thank You, Bob Cafarelli -----Original Message----- From: vonHone, Amy<AVonHone@yarmouth.ma.us> To: 'rcafar@aol.com' <rcafar@aol.com> Sent: Wed, Dec 28, 2016 11:33 am Subject: RE: 25 , 27 MISTY LANE j Hi Bob- I have attached a copy of your plan that I have marked in red with comments to be addressed. The same comments are listed below. Because you need to maintain a 5' swale between the toe of slope and the property line, you will not have enough distance to grade down from the top of system/liner to the property line. As I have suggested for the design across the street, you can reduce the size of the wall and the amount of sand between the wall and the leach field to 1' since the leach design is a field configuration which doesn't allow sidewall towards the total design capacity. The smaller wall/leach field footprint can be shifted towards the front property line (setback variance to be added to list of variances) as long as you can maintain 10' between the leach field and the water main on the street. The elevations of your design are consistent with the system proposed across the street. ! � ! �Provide Engineer Inspection Schedule: (Scedule added to plan.

With the limited area there, I don't see many alternatives to what I have proposed. I'm proposing low profile infiltrators as the allowed bed area is less than a stone system. The groundwater adjustment was 2.8 feet which surprised me for Zone A. ' Would it be allowable to place 40 mil plastic barrier in the ground 5'around the leach bed and taper the grade at 3 to 1 from there. This would eliminate the need for the concrete wall. Since the finish grade is 3' higher than existing grade, the taper would spread out to 9' beyond the plastic barrier. This would require some fill in the road right of way and to 1' from the house foundation which may cause drainage problems. Just a thought. . To be conservative, I flagged the bank as the wetland limit. The actual wetland is beyond where I flagged as there is little to no vegetation there and the topo drops another foot or two from where I flagged. Even at the base of the bank, the ; separation distance is over 70'from the leach bed. Please review and let me know of any changes you feel are needed.

It looks like there has been dumping of landscaping debris at the property,filling in the edge of the wetland ' between the WF 1 and the shed. The property owner should be advised to find a more suitable upland location for disposal of this debris. ; 2. I would like to see the extended wetland line shown on the plan. 3. If the tank excavations need to be dewatered Amy or I should be notified so we can confirm that the filter � fabric is being used effectively to remove sediment. � 4. We are very close to the edge of the wetland in this work area. Please ensure silt fencing is correctly ! installed. The bottom six inches should be buried in a trench. If concentrated flow is anticipated (i.e. due to � dewatering)then a siltation sock should be installed along with the silt fence and securely staked, being sure to � wrap the ends upward to avoid bypassing. It is the applicant's responsibility to implement and maintain appropriate and adequate erosion controls measures throughout the construction process. � Other standard conditions: � 5. All imported fill shall be clean and not contain any foreign debris such as cement, bituminous concrete, rubber, metal,trash, boulders, etc. ! 6. Debris, including litter, shall be picked up immediately.Any excess material that is excavated from the job site � shall be disposed of at a location approved by the Conservation Administrator or in a covered dumpster. No t debris shall be allowed in a Wetland or Waterway. � 7. Washing of equipment/tools shall be done OFF-SITE or handled in a manner appropriate by the Conservation � E Administrator. j 8. No equipment shall be refueled, nor shall fuel be stored within 100 feet of a resource area. 9. The cesspool is to be pumped dry,the connection broken, and filled with clean sand. 10. Any area that is disturbed during construction shall be revegetated immediately or as soon after as the growing season commences. Permanent stabilization shall be carried out in order to minimize erosion. .
