Strathcona County - Interactive Land Use Bylaw
Part 13 : Overlays
13.4 MNO – Mature Neighbourhood Overlay
Purpose
To provide for residential development within mature neighbourhoods that respects and maintains the overall character of these areas.
Area of Application
In addition to the development permit application requirements listed in section 2.7, an application for a development permit shall include a completed architectural elements checklist for mature neighbourhoods form in the form prescribed by Administration that contains the following information:
- (a) the primary architectural style of the proposed development; and
- (b) identification of at least two architectural design elements from the primary architectural style found in the streetscape to be incorporated into the proposeddevelopment; or
- (c) in the event that the primary architectural style of the development is modern, then at least two architectural design elements from a different primary architectural style found in the streetscape must be incorporated into the development.
The two architectural design elements must be selected from those listed in the Mature Neighbourhood Urban Form and Architectural Character Assessment for the primary architectural style, unless the development authority is satisfied that such non-listed architectural design element exists within the streetscape.
The two architectural design elements from the primary architectural style found in the streetscape to be incorporated into the development must not be duplicated (such as two types of windows).
Colours must not be either of the two architectural design elements from the primary architectural style found in the streetscape to be incorporated into the development.
To ensure the preservation of the architectural character within mature neighbourhoods, it is strongly encouraged that a development incorporates more than two architectural design elements from the primary architectural style found in the streetscape.
Landscaping
A landscape plan shall be submitted with a development permit application that contains the following information:
- (a) each of the requirements set out in section 3.8(2); and
- (b) indicates the method of protection to be used to meet the requirements of section 3.8(34) (such as a buffer area to limit soil disturbance or physical barriers).
Existing landscaping and natural vegetation located on the lot should be conserved unless the development authority is satisfied that removal is necessary to efficiently accommodate the proposed development.
Grading
Despite section 2.10 of this bylaw, the development authority shall provide advisement of the decision of an application for a development permit including the legal description, civic address, and nature of the development by sending a letter by regular mail to the owners of adjacent land as identified on the County’s Assessment Roll. This advisement shall not be considered a notice of decision. An example of the area for the advisement to the owners of adjacent land is indicated in the below diagram:
Variance
The development authority may grant a variance to the regulations of this overlay where the proposed development is in accordance with the applicable regulations of section 2.8.
Despite section 13.4(13), the development authority must not approve a variance for a development permit which does not comply with the height regulations of this overlay or the site coverage regulations of the underlying zone.
Development Regulations – Principal Building
Development must comply with Table 13.4(A).
