3.1 ROADS
3.1.1 General Road classification is designated by the MTO and shall be subject to the
approval of the City Engineer. Generally, residential roads are classified as either arterial, collector or
local. Arterial roads are intended to carry large volumes of traffic, moving at
medium to high speeds. Arterial roads serve the major traffic flows between the principal traffic generators and connect with collectors and freeways. Design of arterial roadways are to meet the requirements of the controlling authority.
Collector roads provide for both traffic service and land access. The
primary traffic service function is to carry traffic between local streets and arterial roadways. The City of St. Catharines classifies collector roads as any roadway which, in the opinion of the City and the MTO.
a) will serve as access to 100 or more homes, b) will serve as a traversing route for residents outside of the
subdivision. A local road’s function is to provide for land access to those properties
which directly front on it.
3.1.2 Clearing and Grubbing The road allowance shall be cleared of all trees and shrubs except
where they are to be included in final landscaping, and other obstructions for such widths as are required for the proper installation of all roads, services, and other works. Rough grading shall be done to bring the travelled portion of the road to the necessary grade and in conformity with the cross-section shown on the drawings.
- 25 -
The sub-grade for all roads shall be properly shaped and thoroughly
compacted prior to any application of granular base course materials. In all cases, topsoil shall be stripped for the complete width of the right-of-way and stockpiled at locations approved by the City Engineer.

- 27 -
3.1.4 Alignment Horizontal and vertical alignment is to conform to the requirements as
outlined in Section 3.1.3 Geometric Design and the Ontario Provincial Standard Drawings.
All curves must meet the geometric design standards. Vertical curves are required for changes in grade greater than 1% for
collector and 1.5% for locals. The minimum length of each grade is 6 metres. “Culs-de-sac” are to
have a minimum grade of 0.5% around the longest curb, to ensure adequate surface drainage.
3.1.5 Road Pavement Desing The pavement design for arterial roads will be considered on an
individual basis. The composition and construction thickness of the road pavement shall be designed based upon the following factors:
a) Mechanical analysis of the subgrade soil, b) Drainage, c) Frost susceptibility, d) The future volume and class of traffic expected to use the
pavement. Pavement shall be designed for a minimum ADT – 1000 vehicles and an
anticipated life for 20 years. 3.1.6 Road Allowance Cross-Section The typical road allowance cross-section shall be as per OPS except for
semi-urban cross-section which will be in accordance with the City’s Standard Drawings. Details shall be provided for any approved special provisions required due to unique physical conditions on the site or for existing or future design conditions such as retaining walls, slope protection, culverts, bridges or special crossfall conditions.
- 28 -
3.1.7 Intersections At the intersection of two roads, any transition of the minor classification
road shall not interfere with the normal crossfall of the major road. A 1% to 2% backfall grade shall be provided on all road profiles where local streets intercept with arterial roads. The backfill grade shall be from the crown of the major road to the E.C. or first catchbasin on the local road.
3.1.8 Road Sub-Drains In general, sub-drains will be required to run continuous along both sides
of all roads, as per the City’s standard drawing. However, the City will consider reducing sub-drain requirements for a particular development where a recognized soils consultant indicates that there will be no adverse effects to the road either during or after construction.
In all cases, sub-drains will be required for a minimum length of 6 m on
the upstream side of all catchbasins.
3.2 CURB Curb as shown on Ontario Provincial Standard Drawing shall generally
be used on local streets, “Capping” of curb depressions will not be permitted.
Sawcutting of curb depressions will be allowed. Mountable curbs as per
Ontario Provincial Standard Drawing may be used on the approval of the City Engineer.
Two stage curb poured construction in accordance with City Standard
Drawing may be used with the approval of the City Engineer.

3.3 SIDEWALKS
Concrete sidewalks as per City Standard Drawing shall be constructed
on a) both sides of arterial streets b) at least one side of the collector streets c) at least one side of these streets which serve as a school approach d) at such other locations as may be determined by the Planning
Department of the City of St. Catharines
3.4 BOULEVARDS All boulevards shall be sodded on a minimum of 100 mm of topsoil from
curb line to property line and shall be kept free of rubbish and other materials during the development.
All sod that fails to grow, or dies within one year of placement, shall be
replaced at the developer’s expense.
3.5 DRIVEWAY ENTRANCES The Subdivider shall be required to provide for the excavation, stoning
and maintenance in good condition of each driveway from the travelled portion of the road to the lot line.
The width of curb cut for residential driveways shall be as per City
Standards. The width of curb cut for apartment, commercial and industrial driveways shall take into account the basic width of the driveway and the radius of curvature as further outlined below. Where mutual driveways are constructed between two adjoining properties, the curb cut-out shall be continuous. (Where the curb is less than 1 metre between driveways).
The maximum grade permissible for an access driveway, from the
curbline to the garage shall be 10%. This maximum grade is not recommended and should be employed only in exceptional cases where physical conditions prohibit the use of lesser grades. There shall be a minimum grade of 2% from the streetline to the curbline where sidewalk exists.
- 30 -
The radius of curvature from the road into apartment, commercial and industrial driveways shall be designed to accommodate the anticipated vehicular traffic without causing undue interference with the traffic flow on the street (ARTC Traffic Turning Templates).
Standard Entrances access are as per Ontario Provincial Standard
Drawings.
3.6 DAYLIGHTING When subdivision streets intersect with collector or arterial or local
streets, the Engineer may request land for daylighting triangles. The size of the daylighting required is based on the classification of the intersecting roads and shall be in accordance with Standard Drawing. The City Engineer may request additional daylighting above these requirements if he deems it necessary.

6.2.1.6 Crossings of Watermains Over and Under Sewers
Under normal conditions, watermains shall cross above sewers with sufficient vertical separation to allow for proper bedding and structural support of the watermain and sewer main.
When it is not possible for the watermain to cross above the sewer, the
watermain passing under a sewer shall be protected as follows: a) A vertical separation of at least 0.50 metre shall be provided between
the invert of the sewer and the crown of the watermain. b) The sewers shall be adequately supported to prevent excessive
deflection of joints and settling. c) The length of watermain shall be centred at the point of crossing so that
the joints will be equidistant and as far as possible from the sewer. 6.2.1.7 Utility Crossings Where watermains cross over or under utilities other than sewers, the
clearance and type of crossing provided shall conform to the requirements of the particular utility involved and provide proper bedding and structural support of the watermain and utility.
6.2.1.8 Dead Ends Wherever possible, the distribution system shall be designed to eliminate
dead-end sections. Where dead-ends cannot be avoided, they shall be provided with a fire hydrant, flushing hydrant or a 50 mm blowoff for flushing purposes.
- 60 -
6.2.2.0 LINE VALVES 6.2.2.1 Type
Gate valves shall be used on all watermains 250 mm diameter or less in size.
Butterfly valves shall be used on all watermains of 300 mm diameter and greater.
All valves shall be of the approved type with non-rising stem and a 200 mm
square operating nut opening counterclockwise.
6.2.2.2 Sizes The sizes of the line valves shall be the same size as the watermain.
6.2.3.3 Number, Location and Spacing Generally, a minimum of two valves are required at a tee intersection and a
minimum of three valves are required at a cross intersection. The valves shall be located at the point where the projections of the streetline intersects the watermain. Valve boxes and chambers shall be located in boulevards whenever possible.
Line valves shall be located such that 20 houses can be shut-off from another

appurtenances to a distribution system shall not be connected directly to any sanitary or combined sewer, nor shall blow-offs or air-relief valves be connected directly to any such sewer.
Such Chambers or pits shall be drained to the surface of the ground where
they are not subjected to flooding by surface water, to absorption pits or to a sump within the chamber where ground water level is above the chamber floor or storm sewer.
In order to minimize the total number of chambers on any project, care should
be exercised in locating the line valves, air reliefs, drains, etc., with a view to combining these functions in a single chamber.

hose length of 37.5 metres.
6.2.3.4 Branch Valves and Boxes All hydrants installed on watermains shall be installed with 150 mm diameter
branch valve and box.
6.2.4 WATER SERVICE CONNECTION 6.2.4.1 General
In new developments, the service connections shall be installed in
accordance with the Standard Drawings terminating at the property line. No service connection shall be made to watermains greater than 400 mm
diameter.
- 63 -
6.2.4.2 Pipe Sizes
a) The minimum size for service connections shall be 20 mm diameter
except when the length of the connection from the main to the building setback exceeds 30 metres, then the minimum size shall be 25 mm diameter.
b) Service connections for multiple family dwellings shall be sized to
provide capacity equivalent to a 20 mm diameter connection to each dwelling unit.
c) Service connections for blocks, commercial and industrial areas shall be
sized according to the intended use.
6.2.4.3 Location Water service connections shall be installed at the mid-point of the frontage of
a single family lot. Water service connections shall not be located under a driveway, if possible.
The location of water service connections for semi-detached lots shall suit the house style in accordance with the Standard Drawing.
6.2.4.4 Death
Curb and Gutter Roads – water service connections shall be installed 1.70
metres minimum below finished centerline road grade. Open Ditch and Unimproved Roads – in no case shall the cover of the water
service connection be less then 1.70 metres.
6.2.4.5 Mainstops All domestic water service connections shall have mainstops installed at the
watermain equal to the water service connection diameter.
- 64 -
6.2.4.6 Curb Stops and Boxes
All service connections shall have curb stops and boxes installed at an
approved location.
6.2.4.7 Materials Water service connection 50 mm diameter or less shall be type “K” copper or
polyethylene. Water service connections larger than 50 mm diameter shall be polyvinyl chloride. All material, fittings and appurtenances shall be CSA and A.W.W.A. approved.

7.1 GENERAL 63
7.2 OBJECTIVES 63
7.3 DESIGN CRITERIA 64
7.4 PREGRADING 65
- 66 -
7.1 GENERAL
New development lot grading shall conform to the latest edition of the City of St. Catharines “Storm Drainage Manual”. Such lot grading must be prepared by a P. Eng. Or O.L.S.
At the time of final acceptance the Consulting Engineer shall provide the City
with an as-built grading plan for the subdivision showing the finished grade of all key points as of a certain date. Minor variations will be allowed, provided the intent of the proposed approved plan was followed and there is not problems. This plan must carry the following certifying statement, signed and sealed by a Professional Engineer or O.L.S.
“I have taken the field elevations shown ( ), and hereby certify that the
house grade and the grading of each lot or block is in conformity with the submission for a building permit. I further certify that as of this date that each lot or block within this subdivision drains satisfactorily and the grading of this subdivision has not adversely affected adjacent lands.”
It will be the responsibility of the developer to ensure that lot grading is
completed to the satisfaction of the City Engineer. Lot grading shall be in accordance with the approved drawings.
Any deviation from the overall grade plan will require approval of the City
Engineer.
7.2 OBJECTIVES The lot grading plan will be reviewed and, therefore, should be designed with
the following objectives in mind: a) The establishment of independent and adequate drainage for each lot.
This can be provided by either rear to front drainage or split drainage intercepted in a rear yard swale, catchbasins, etc.
b) The establishment of lot and house grades which are compatible with
existing topography and surrounding development. This will achieve maximum utility and protection for the property and enhance its appearance.
c) The establishment of gradual gradation without terraces, steep slopes,
or abrupt changes in grade. These are not only difficult to maintain, but also accentuate the artificiality of the new topography.
d) Defined ditch like swales should be avoided.
- 67 -
7.3 DESIGN CRITERIA a) The maximum allowable difference in elevations between abutting lots
along the rear lot line is 0.3 metres. The slope should be located on the lower property.
b) Slopes shall have not less than a 3:1 slope unless approved by the City
Engineer. c) The use of rear yard swales, embankments or retaining walls should be
minimized. d) Grass surfaces shall have a minimum slope of 1%. e) Grading around houses and buildings shall direct the water away from
the structure. f) Swale depth will vary depending on location and safety consideration
(preferably not more than 500 mm). g) Swale grades are recommended to be at least 1.0 percent. In clay-type
soils swales shall be underdrained. h) The maximum runoff typically allowed in a swale between two houses is
the drainage from those two yards. i) The maximum swale length shall not exceed 90 metres. Such drainage
shall not outlet along the surface between houses. Not more than 6 lots shall be serviced by one basin.
j) When rear lot catchbasins are installed to pick up surface drainage, the
municipality maintains them, in which case, easements must be provided by the developer. The width of such easements shall be 3 m.
k) The proposed elevations at the boundary of the subdivision shall match
existing elevations and accept any surface drainage from the adjacent lands.
l) Provision is to be made to prevent ponding of water on lands bordering
the subdivision and within the subdivision during construction. m) Where below grade garage driveways are designed, the portion
between the property line and street must drain towards the street.
- 68 -
7.4 PREGRADING The subdivision shall be pregraded prior to issuance of building permits and the
Consulting Engineer shall clarify that such work has been done. Pregrading requires that all lot corners, rear yard catchbasins, swales and underdrainage of same and boulevards have been constructed in accordance with the “General Grading Plan”. The Niagara Peninsula Conservation Authority may have specific concerns related to pregrading. Consultations with the NPCA prior to and during the pregrading of the site is recommended.
