Meetinghouse Hill <br /> Page two <br /> junction of the "Y" but will require traffic to stop and back around in order <br /> to leave the development. There is not sufficient width within the "Yn to <br /> create a cul-de-sac in its present configuration. A cul-de-sac could be <br /> provided at the end of the road near Lot 6 and the drainage easement. <br /> However its diameter would extend into the drainage area provided on <br /> Lot 5 and would require extensive filling in order to achieve reasonable <br /> road grades. <br /> 3. Sheet 1 is the plan that will be used to define the lots on the ground and <br /> will be used as a recordable plan for conveyance purposes. It is <br /> recommended that the road be bounded with concrete monuments at <br /> each change in direction as required by the Subdivision Rules and <br /> Regulations. Placing the monuments after road construction has been <br /> completed will help to define each lot for prospective buyers. It will also <br /> help to reduce future costs of retracement surveys of lot lines within the <br /> development. <br /> 4. The plan shows that the property is tied to the layout of Meeting House <br /> Road but lacks the necessary dimensional ties to make it complete. The <br /> dimensional ties should be noted on the plan. <br /> 5. It is recommended that the drainage area on Lot 5 be defined with <br /> appropriate metes, bounds and area. <br /> 6. If a signature block is required for Board of Appeals signatures and dates <br /> of approval it should be placed on this sheet. <br /> 7. It is recommended that the word "Preliminary" be removed from the plan <br /> so as not to confuse it with an ordinary Chapter 41 preliminary plan that <br /> has no standing and cannot be recorded in the Barnstable Registry of <br /> Deeds. <br /> Sheet 2 of 4 Site Grading and Drainage <br /> 1. Standard practice under the Planning Board Rules and Regulations would <br /> require a statement by the surveyor stating that the topographic survey <br /> was done on the ground. It is assumed that the contours shown are the <br /> results of such a survey but its source should be noted. The existing and <br /> proposed contour interval is 2 feet which is acceptable. <br /> 2. Several of the proposed dwellings indicate a "T.F." number that could be t <br /> interpreted as "top of floor" or"top of foundation". This should be clarified <br /> or noted by the engineer. The number in many instances is <br /> approximately 12" above the finished outside grade. This would be <br /> acceptable for top of foundation but not for top of floor. <br /> 3. It is noted on the plan that there is an existing town drainage structure <br /> within the location of the proposed entrance roadway. It may be <br /> necessary to relocate this structure. Its construction is important since <br /> any structure within the proposed roadway must be able to withstand H- j <br /> 20 wheel loading. The existing Meeting House Road drainage should not <br /> be connected to the proposed new drainage unless adequate sizing has <br /> been provided in the design. The town catch basin that discharges to this <br /> unknown leaching area may also need reconstruction since a portion of <br /> the runoff swale is within the limits of the proposed new pavement. The <br /> Mashpee Public Works Department should be consulted regarding any <br /> modification of town drainage or work within the limits of Meetinghouse <br /> Road. <br /> 4. The driveway that leads to the dwellings on Lot 1 and Lot 2 is a shared <br /> driveway. At a point 60 feet from the Meeting House Road pavement it <br /> narrows to a width of 12'. This width would not be sufficient for two cars <br />
