7.0 Design

7.1 Introduction The following section outlines certain design criteria and submission requirements applicable to site servicing, stormwater management, surface works, and landscaping requirements for site plan and subdivision development in the City of Waterloo. All designs must be completed in accordance with applicable provincial standards, guidelines, codes, municipal specifications, policies, by-laws, engineering best management practices, and all applicable legislation. The following list references documents that may be relevant to the design process, including but not limited to:

• MOE Design Guidelines for Drinking Water Systems • MOE Design Guidelines for Sewage Works • MOE Stormwater Management Planning and Design Manual • Ontario Provincial Standard Specifications • Region of Waterloo Design Guidelines and Supplemental Specifications for Municipal Services (DGSSMS) • Ontario Building Code • Region of Waterloo By-laws • City of Waterloo By-laws • City of Waterloo Policies • City of Waterloo Stormwater Management Guidelines • Laurel Creek Watershed Study • Urban Design Manual • Landscape Design Process and Requirements Manual • Northdale Urban Design and Built Form Guidelines

7.2 Design Criteria

7.2.1 General The design information included herein is intended to provide initial clarification on design issues and to delineate specific requirements for development within the City of Waterloo. This manual is not intended to be a complete reference for detailed design. Any questions about these requirements should be referred to City staff at the early stages of the design process. The Region of Waterloo, in conjunction with area Municipalities, has prepared the DGSSMS to create a common set of design guidelines and contract specifications for servicing works within the Region. The City of Waterloo endorses these standards and design works within the City must conform to them. The DGSSMS take precedence over the related OPS documents and they are to be used in conjunction with the City’s design standards as outlined in this manual.

7.2.2 Exceptions to the DGSSMS Exceptions to the Region standards that are specific to the City of Waterloo are indicated below. Items are listed with the corresponding section numbers found in the Design Guidelines. A.4 Chief Municipal Engineer The Chief Municipal Engineer for the City of Waterloo is the Director of Engineering Services. B.1.6 Easements The minimum easement width shall be the greater of: a) 2 x depth where the depth is from the proposed final grade to the invert rounded up to the nearest half metre, or: b) 5.0 m

.2

D.2.5.6.1 Non-Metallic Mains Anodes shall not be connected to the tracing wire. They shall be connected to each metallic fitting using a brass grounding clamp to connect the lead to the fitting. D.2.5.12 Wrapping All metallic watermain fittings (excluding curb/main stops and brass fittings) and appurtenances including saddles, valves, tees, bends, etc. are to be wrapped with an approved petrolatum system consisting of paste, mastic and tape. All components of the system must be provided by the same supplier. D.2.6.2 Valves Road levellers are not permitted. The valve box must be raised to final grade. D.3.3.1 Maintenance Hole Lid Adjustment Tolerance Ring maintenance hole risers are not accepted. D.3.3.3 Maintenance Hole Connections Resilient connectors are not required on storm maintenance holes in the City of Waterloo. D.3.3.4 Maintenance Hole Benching All catchbasin maintenance holes shall not be benched, but shall be installed with a 600 mm deep sump.

7.2.3 Grading All sites must be graded to match existing elevations at the property limits, to provide positive drainage from the site and to convey surface runoff to approved locations at controlled rates. Grading on adjacent lands will only be considered with written permission from the applicable land owner.

Erosion Control Erosion control measures must be in place throughout construction to minimize soil and sediment transportation, and to reduce surface water flows from the site.

Lot Grading Proper drainage should not cause damage or adverse effects to any adjacent property including roads and public lands. The intent of the following Lot Grading Criteria is to provide for positive drainage away from buildings and permit the reasonable use of the property:

• Drainage features should be designed so that one property does not accept an unreasonably larger amount of runoff than the others

• Backyard is designated as the area from the rear foundation of house to rear property line

.2

66


• The grading plan should indicate that all of the water leaders should drain to the front of the property. If conditions permit, then roof water leaders can drain to the backyards

• Landscaped areas on all lots must be finished with topsoil to a minimum depth of 0.150 meters prior to sod placement

• The proposed driveway entrances shall be as far away as possible from intersections; (Maximum grade within the City owned boulevard shall not exceed 4%

• Maximum grade within a 2m easement for municipal and gas use shall not exceed 4% • Designer shall ensure embankments designed to match proposed grades to existing grades at property line

maintain positive drainage • Hydro transformer concrete pad shall be placed at an elevation outside of the 100yr ponding limits • Hydro poles and other street furniture shall off set driveway entrance including apron radius by 1.5m • Cross sections may be required at the discretion of the City to clarify the proposed grading, particularly in

relation to adjacent properties, proposed elevations on paved areas, around proposed buildings, along swales, along roadways, parking areas, driveways, catchbasin rim elevations and any other elevations necessary to establish the grading and drainage patterns for the development

Lot Grading Detail In subdivisions, lot grading shall be designed in accordance with the following City of Waterloo Standard Drawings:

Lot Drainage Type ‘A’ W-302 Lot Drainage Type ‘B’ W-303 Lot Drainage Type ‘C’ W-304 Lot Drainage Type ‘D’ W-305

• Drainage flows shall be directed away from houses • Where feasible, storm drainage is to be self-contained within development and/or phase limits • No front yard catchbasins shall be allowed. Side-split lots shall be in general conformance with the lot

grading criteria • Typical toe of slopes for walkout and back-split lots shall be designed at 22 meters from front property

line, based on a 6-meter setback with a 16 metre building length

Lot Grading Criteria The following criteria are to be used as a guide in planning the various types of lot grading unless severe existing conditions require special consideration. In those situations specific lot grading criteria will be prepared for that development:

Driveways Optimum gradient 4% Minimum gradient 2%

Maximum gradient Maximum Cross Slope

8% 5%

Walkways/Trails

Maximum gradient Maximum cross slope

8% 4%

Minimum cross slope (where gradient is less than 2%) 2% Parking Areas Maximum slope 5% Barrier Free Parking Maximum slope 2% Boulevards As per City of Waterloo Standard Road Cross-sections (appendix L) Paved Utility Area Optimum slope 1% Maximum slope 6% Minimum slope 0.5%

• If the average yard slope exceeds 6%, a retaining wall or 3:1 slopes will be required to reduce the grade to

an acceptable amount (An exception will be made for where noise attenuation berms are required) • Sod cannot be maintained on slopes greater than 2:1, therefore, such slopes are to be avoided. If required,

these slopes will be covered in low maintenance ground cover • There shall be a minimum 0.6 m wide surface at 2% slope away from the house along both sides of the

building except where side yard setbacks from lot lines do not permit. This requirement is needed for easy access to the rear of the house

• The alignment of swales conveying runoff from more than 2 lots shall not change more than 45°. If this occurs, additional catchbasins shall be installed to maintain objectives stipulated elsewhere in this specification

• In cases where sideyard swales are proposed with their center-line on a common property line, and the adjacent property is vacant, the swale must be installed to property line by the builder. This grading is required in order to:

• provide for proper drainage of completed lots when they border vacant lots • ensure that neighbouring lots are constructed to match the proposed drainage design • minimize or eliminate grading activity on completed lots when vacant lots are finally built

upon • limit the construction impacts to new homeowners

.2

68


An adjacent property is deemed to be vacant when, at the time of the final grading and landscaping of the subject lot, the adjacent lot is still unsold, excavations for the foundation have not begun, or final grading and sod are not anticipated for some time.
