definition as published in Preparation of Environmental Statement
and Guidelines for Discussion of Cultural Resources).
Professionally conducted surveys, carried out in accordance
with the standards and guidelines described in the Environmental Review
Primer consisting of the following levels of investigation: Archaeological
Assessment Survey (Phase 1), Reconnaissance Survey (Phase 2), and
Intensive Survey and Data Recovery Program (Phase 3).

list of recognized professional archaeologists.
(3)
An archaeological assessment study shall be completed on any subdivision
submitted to the Commission. Results of the survey can be supported
by the Town of Newtown Archaeological and Historical Sensitivity Map,
generated by the Newtown GIS Department. If an archaeological or archaeological
assessment survey is significant, a complete archaeological assessment
survey and report shall be prepared in accordance with the standards
and guidelines described in the Environmental Review Primer and shall
accompany the application. The survey and report, prepared at the
applicant's expense, shall be conducted by a professional archaeologist
with credentials recognized by the state Historical Preservation Office
or the Office of the State Archaeologist.

Where any portion designated for development within a subdivision
tract lies within an area identified as significant by the archaeological
assessment survey, an archaeological reconnaissance survey and report
shall be conducted at the applicant's expense.
(5)
The archaeological reconnaissance survey and report shall specifically
identify, locate and describe all archaeological and historical resources
of the site and shall identify their boundaries. The report shall
also analyze and evaluate the archaeological and environmental data
and shall include mapping of resource-free areas.
(6)
If a site is determined by the Commission, in its review of the application,
to possess significant archaeological or historical merit, it shall
withhold approval of the plan unless the applicant:
(a)
Restricts the full extent of the area found to possess historical
or archaeological significance, so as to preserve the same area free
from development, by means of a permanent preservation easement granted
to the Town or a recognized conservation entity, with perpetual rights
to conduct limited archaeological research on the same area at reasonable
times; or

acceptable means deemed appropriate by the Commission to prevent excess
stormwater runoff and to ensure adequate on-site recharge.
A.
A performance bond shall be filed with the Commission guaranteeing the improvements required for existing and proposed streets, water supply, water storage tanks for fire suppression, sanitary sewer and storm drainage facilities and any other improvements required by these regulations, including without limitation the improvements required by §§ 560-23, 560-27 and 560-32 hereof. Said performance bond shall assure the installation and completion of the improvements before an agreed date, not to exceed five years.

at the subdivider's expense in the office of the Town Clerk within
90 days of the expiration of the appeal period specified under Section
8-8 of the Connecticut General Statutes, as amended, or in the case
of an appeal, within the period of time specified under Section 8-25

1977, failure to complete all work within such five-year period shall
result in automatic expiration of the approval of such plan, provided
the Commission shall file on the Newtown Land Records notice of such
expiration date on the approved subdivision plan on file in the office
of the Newtown Town Clerk, and no further lots shall be conveyed in
the subdivision except with approval by the Commission of a new application
