(d) Minimum and maximum cover depths for plastic pipes are provided on the Town standard detail for "Storm Drain Plastic Pipe - Bedding and Installation."

(e) Minimum slopes for enclosed conduits shall be 0.5%.
(f) Maximum flow velocity for the design storm shall be 12 feet per second.
(g) Minimum circular pipe size within or serving roadways or parking lots with more than eight parking spaces is 15 inches.

(2) Catch basins.

(a) All catch basins shall have four-foot sumps to trap sediment, unless otherwise approved for valid reason (e.g., utility conflict), and appropriate hoods per the CT-SWQM.

(b) Catch basins shall not be located in front of curb ramps or otherwise within intended walking paths, unless practically unavoidable. Where so unavoidable, special grates designed for pedestrian traffic shall be used.

(3) Collection and conveyance system calculations and modelling.

(a) Non-culvert subsurface conduits shall be designed to convey the flow from the design storm in free open channel flow, non-surcharged condition.

(b) Pipe inlets at catch basins with sumps will effectively function as culvert inlets; the lesser value between the inlet capacity at the upstream catch basin and the maximum free open channel flow capacity of a pipe shall be used in conveyance system calculations and modelling.

(c) Bypass flow shall be appropriately accounted for at catch basin grates at grade.

(d) All systems shall be evaluated for the 100-year flow:

[1] Determine where excess water will flow and what will be flooded.
[2] Problematic flooding should be avoided; flood waters shall not reach an elevation that will enter any existing or proposed building.
[3] Flood waters that end up in different locations than stormwater that is being conveyed by the drainage system shall be appropriately accounted for in the modelling.

 

Stormwater quality.

(1) The provisions of the CT_SWQM shall be complied with in the planning, design, construction, operation, and maintenance of all stormwater facilities as relates to stormwater quality and treatment.

(2) As a point of emphasis, LID site planning and design shall be used to the "furthest degree possible," as set forth in the CT_SWQM. The Commission may, at its discretion, require an alternatives analysis to determine compliance with this requirement.

 

Stormwater quantity.

(1) Post development peak flow rate from the subject site to any downstream location shall not increase for the 100-year storm event.

(2) Peak flow rates from the subject site to any downstream location shall not increase for the two- or ten-year storm events, subject to:

(a) Any requirements from the Inland Wetlands and Watercourses Commission to maintain certain flow levels with respect to a downstream wetland, shallow water body, vernal pool, or small watercourse, etc.
(b) In circumstances where stormwater retention possibilities are appropriately limited, peak flow rates from the two- and/or ten-year storm events may be allowed increase by an insignificant amount where it is demonstrated that there is a practical advantage to the overall design of the peak flow attenuation system in doing so.
(c) Note: The CT_SWQM requirement to control the two-year peak flow rate to 50% of predevelopment rate is a goal, and this requirement is not globally applicable to these regulations.

(3) Flow characteristics to any downstream location shall not be altered so as to cause, or threaten to cause, damage, erosion, or other harm to any downstream location.

(4) Subject to § 470-713C(1), § 470-713C(2), and § 470-713H(2)(a) and any groundwater pollution concerns, stormwater retention shall be achieved to the "maximum extent achievable," as set forth in the CT_SWQM.

Shared stormwater management facilities. See § 470-713I for details.

Maintenance. See § 470-713J for detailed information.

See § 470-713: Stormwater management. for more detailed information.

(1) For a special permit use, the applicant shall provide a traffic impact analysis, in accordance with the Institute of Transportation Engineers requirements for traffic impact studies. Such analysis shall evaluate traffic generated by a proposed development and its probable impact on existing roads and intersections in the area for:

(a) Any proposed nonresidential development containing a gross floor area of 10,000 square feet or more;

(b) Any development which, in the Commission's judgment, could generate high levels of traffic, exacerbate existing traffic conditions, or create a traffic safety issue; or

(c) Any intersection that would have 100 or more vehicles trips in a peak hour.

(2) The traffic analysis shall be prepared by a professional traffic engineer and shall include:

(a) Past and present roadway conditions including location and number of accidents;
(b) Existing and projected traffic volumes (average daily traffic, peak a.m. and p.m.);
(c) Existing roadway capacity; volume and capacity ratios;

(d) Estimates of vehicle miles traveled, and vehicle trips generated that assesses:

[1] The anticipated traffic impact of the proposed development; and
[2] Potential mitigation strategies, such as reducing the amount of required parking for a development or requiring public sidewalks, crosswalks, bicycle paths, bicycle racks or bus shelters, including off-site;
 

(e) Proposed sight lines; and
(f) All calculations shall be based on facts and reasonable generation factors of the site, affected road networks, and intersections.

(3) In analyzing potential traffic impacts, the Commission shall consider:

(a) The effect of the proposed development on traffic conditions on abutting streets and any nearby intersections that would have 100 or more vehicle trips in a peak hour;

(b) The patterns of vehicular circulation in relation to the adjoining street system;

(c) The adequacy of:

[1] Traffic signalization, traffic channelization, left-turn lanes and roadway widths of adjoining streets;
[2] Vehicular stacking lanes and/or distances;
[3] Pedestrian drop-off areas; and
[4] Other traffic or transportation facilities to accommodate the proposed development.
 

(d) Anticipated traffic impact of the proposed development and potential mitigation strategies.

(4) A significant traffic impact shall be presumed where the projected traffic volume:
 

Increases the study area intersection/roadway peak hour volume by 15% for intersections/roadways with an existing peak hour volume over 100, and by 25% for those lower than 100.

Reduces the projected peak hour level of service to "D" or lower for the overall intersection as defined by the Transportation Research Board (TRB) Highway Capacity Manual (HCM) for automobiles.

(5) The Commission shall not approve a proposed development with a significant traffic impact unless:
 

(a) The Commission finds that the development satisfies the special permit criteria and would enhance the character surrounding neighborhood; or

(b) The proposal is revised to mitigate the adverse impacts (such as limiting the number of curb cuts along heavily trafficked roads, widening roadway lanes, adding roadway lanes, adding turning lanes, providing signal modifications, providing traffic signalization, or similar improvements).

See § 470-708: Traffic and visibility at intersections and driveways for more detailed information.

(a) On a corner lot in any district, no planting, snow, structure, fence, walls or obstructions to vision more than three feet in height shall be placed or maintained within the triangular area formed by the intersecting street lines and a straight line connecting points of said street lines, each of which points is 25 feet distance from the point of intersection.



(b) Any obstruction to vision which in the opinion of the Canton Traffic Authority is a traffic hazard shall be removed as a violation of these regulations.

(2) Driveways. In order to provide adequate room for emergency vehicles to turn into driveways and access all buildings and parcels within the Town of Canton, all new driveways (including alleys, private roads, and other access ways) shall provide the following minimum clearances for emergency vehicles, regardless of the paved width of the driveway:
 

(a) No building, fence, wall, lamp post, telephone pole, mailbox, sign, or other structure, nor any trees, boulders, or other obstructions shall be erected, placed or installed alongside any driveway so as to reduce the access to less than 14 feet wide at any point;

(b) No building, fence, trees, boulders or other obstructions shall be erected, placed, or installed within the triangular areas on either side of the driveway at its intersection within the travel portion of the road, formed by connecting the outer points of a line measured 25 feet on the road, (centered on the driveway), and a parallel line 14 feet wide (centered on the driveway) at a distance of 25 feet from the travel portion of the road [Diagram 708C(2)];

(c) If buildings are on the lot within 50 feet from the traveled portion of the road and can be easily accessed from the road, the Commission may exempt the parcel from the requirements of this section as part of any site plan approval; and

(d) Any bridge or culvert in the travel portion of the driveway shall provide enough width to accommodate modern day fire apparatus and be able to sustain the weight of a static fire service engine or tanker.
