*
Right-of-way width may be reduced to 50 feet if subsurface drainage is used. Right-of-way width for roads in subdivisions approved by the planning board prior to May 2003 may be reduced to 50 feet.
**
Specifications for driveways constructed prior to acceptance of street.
Driveways constructed after acceptance must be approved by the director of the public works department and meet standards of Chapter 17, Article III, Street Openings.
b. 
Continuation of existing streets. Existing streets will be continued at the same or greater width, but in no case should they be extended at less than the original width.
c. 
Dead ended streets.
1. 
All dead ended streets shall be provided at the closed end with a circular turnaround, having a property radius of 68 feet and a traveled way radius of 55 feet.
2. 
Dead ended streets in excess of 1,000 feet to the start of the cul-de-sac will be reviewed by the Fire Chief for fire safety concerns. The Fire Chief will make a recommendation to the City Council prior to acceptance.
3. 
For dead ended streets dedicated, constructed and used for public travel prior to 1973, the following will be required:
i. 
For streets within the hydrant district:
A. 
0 — 300 feet in length, turnarounds may be omitted.
B. 
300 — 600 feet in length, a Y shaped turnaround may be used instead of the circular turnaround. The Y shaped turnaround has legs which have center lines which are at 120° to each other. The legs will have twenty-five-foot wide pavement with two-foot wide gravel shoulders and each leg shall be at least 40 feet in length, measured along the center line.
C. 
Over 600 feet in length, circular turnarounds as described above will be required.
ii. 
For streets outside the hydrant district:
A. 
0 — 400 feet in length, Y shaped turnarounds as described above may be used.
B. 
Over 400 feet in length, circular turnarounds as described above will be required.
d. 
Roadway structure. In all cases the pavement structure of streets and ways shall be designed in accordance with the local soil conditions and anticipated service loads. Design shall be based on current design procedures and approved by the City engineer.
e. 
Storm drainage. All streets shall be provided with adequate open or underground drainage facilities when, in the opinion of the City engineer, they are necessary to provide for the removal of storm water to prevent flooding of pavement and erosion of adjacent surfaces. If underground drainage is provided, curbing will be installed unless waived by the street commisioners and the City engineer. Appropriate erosion control measures will be incorporated into the design to minimize any potential erosion problems.
f. 
Blocks. The length, width and shape of blocks shall be determined with due regard to:
1. 
Provision of adequate building sites suitable to the special needs of the type of use contemplated;
2. 
Zoning requirements as to lot sizes, dimensions and density;
3. 
Needs for convenient access, circulation, control and safety of street traffic;
4. 
Limitations and opportunities of topography;
5. 
Block lengths shall not exceed 1,000 feet or be less than 500 feet; and no block shall be more than 500 feet in width nor less than 200 feet for residential use. This restriction shall not apply in a rural district provided that each lot in each block measures not less than two acres in area. Furthermore, these requirements need not be met in cluster subdivisions.
g. 
Phased developments. The City Council may accept a street without the cul-de-sac being paved if the developer proposes an extension of the proposed street within three years with the following conditions:
1. 
The cul-de-sac is completely constructed except for the pavement.
2. 
An easement is given to the City to plow the cul-de-sac.
3.

b. 
Any storm or sanitary sewer, or other underground utilities in said street or way shall be constructed before any subsurface pavement structure is constructed.
(4) 
Inspections.
a. 
The construction shall be inspected and certified by a Maine Registered Professional Engineer, at the developers cost, that the street has been constructed in compliance with good engineering practices and the ordinances of the City of Old Town.
b.

1. 
Prior to the placement of pavement and after the subsurface improvements have been completed.
2. 
Upon final completion of the proposed street.
3.
