2. The plan set does not identify the total area of site disturbance associated with
constructing the extension of Parker Lane. The applicant should confirm if the proposal
exceeds 1-acre of disturbance or is part of a larger common plan of development that
will ultimately disturb an area equal to or greater than 1-acre, which would require filing
a Stormwater Management Permit. A draft copy of the Stormwater Management Rules
& Regulations can be found on The Town of Barnstable’s website at
https://www.town.barnstable.ma.us/Departments/PublicWorks/Projects_and_Updates/St
ormwater-Management-Regulations.asp.
3. A Road Opening/Trench Permit will need to be obtained prior to commencing
construction.

Review of Waiver Requests
It should be noted that the waiver requests shown on the plan set do not match the waiver requests
listed on the Waiver Request letter. The applicant should confirm all waivers requested between the
plan set and the Waiver Request letter and resubmit the letter including all applicable waiver requests.
1. 801-24.A.1(a)[13] Soil Borings: Test pit logs were provided for review in the application
package and showed consistent soil type and depth to groundwater. However, the test pits were
not shown on the plan set provided for review. It is recommended that one test pit be
performed within the proposed roadway at the intersection of Parker Lane and Old Stage Road.
Further, it is recommended that at least one test pit be performed at each drainage system
location to at least 4’ below the proposed bottom of the infiltration system.
2. 801-24.A.1.(a)[16] Environmental Analysis Report: No objection to this request. However, the
plan should provide a statement as to the location of the property relative to those areas defined
in Section 801-24.B(3)(k).
3. 801-24.C Profile Sheet: We do not recommend a waiver of this requirement as there are fairly
significant grades along the roadway which warrant a profile to confirm the proposed roadway
meets the maximum slope requirements, meets vertical curve requirements, among others.
4. 801-24.E.(6-9) Review: No objection to this request. It was also noted that this request is not
mentioned on the waiver request letter but is mentioned on the plan set. The applicant should
clarify if this is a request waiver.
5. 801-24J.(5) Binder Course: No objection to this request.
6. 801-24N.(3)(a) Hydrant System: Defer to the Fire Chief’s recommendation. It was also noted
that this request is not mentioned on the waiver request letter but is mentioned on the plan set.
The applicant should clarify if this is a request waiver.
7. 801-27 Drainage: We do not recommend a waiver of all requirements within 801-27. Not all
subsections are applicable to the stated reason for the waiver. The applicant should reference
specific subsections that waivers are being requested from. Further comments on the drainage
design and analysis have been provided above.
8. 801-27.C.(4) Drainage. 3:1 Slopes: No objection to this request. It was also noted that this
request is not mentioned on the waiver request letter but is mentioned on the plan set. The

leaching structure which should be constructed in accordance with these requirements.
13. 801-44 – Roadway Foundation: The applicant has requested a waiver to allow a 9-inch gravel
base. The standard cross section requires 12 inches of gravel base plus 3 inches of bituminous
concrete. It is recommended that a minimum 12-inch gravel base be provided. If no asphalt is
