WHEREAS pursuant to the provision of Section 633(1) of the Municipal Government Act, RSA 2000, Chapter M-26, the Council of the Town of Trochu (hereinafter called the Council), has adopted the Northwest Area Structure Plan Bylaw 2020-16;
AND WHEREAS the Council deems it desirable to amend the Northwest Area Structure Plan Bylaw 2020-16; and
NOW THEREFORE the Council hereby amends "Schedule 1" of the Northwest Area Structure Plan Bylaw 2020-16; as follows:
1. In the Executive Summary replace the second paragraph with the following:
"The lands within NW 17-33-23-4 W4M (the Plan Area) are currently owned by the Town and the Trochu Housing Corporation. The lands are situated along the north and western boundary of the Town. This ASP is a statutory planning document adopted by a bylaw pursuant to the Municipal Government Act (Section 633) to satisfy Town's Municipal Development Plan's vision for residential and commercial development in this location."
2. Under the heading 1.1 PURPOSE OF THE AREA STRUCTURE PLAN:
- a. replace the first paragraph with the following:
"The Northwest Area Structure Plan (ASP) is a long-range statutory planning document that provides a roadmap for future development of a specific area of the Town of Trochu (the Town), specifically, the lands within NW 17-33-23-4 W4M (the Plan Area)."
- b. delete the last sentence in the 5th paragraph as follows:
"The increased density outlined in this ASP has the ability to achieve approximately 196 to 263 housing units, not including the units dedicated to the seniors housing facility".
3. Under the heading 1.2 PLAN INTERPRETATION delete the 4th and 5'h paragraphs as follows:
"Neighbourhood commercial should be interpreted similarily to the Central Commercial District in the Town's MDP. Though not located within the urban core, the Neighbourhood Commercial identified in the ASP will provide opportunities for retail, service, and employment and act as a buffer between Highway Commercial and residential land uses in the Plan Area.
Highway Commercial areas should be interpreted similarly to the General Commercial District in the Town's MDP, located adjacent to the Highway 21 corridor. The MDP's Figure 9 Future Land Use Map identifies the area north of North Road along highway frontage as highway commercial."
4. Under the heading 1.3 PLAN ORGANIZATION, Part 2 Plan Policies, replace the sentence with the following:
"Part 2 builds off Part 1 and contains goals, objectives and policies for the Plan Area addressing land use, servicing, and infrastructure."

- b. Delete the following text:
## "Town of Trochu MDP
To accomodate the demand for coventional single detahced dwellings, raw land will need to be developed. Future expansion would be best located to the north of North Road. This area is desirable for residential development as it is serviceable at a relatively low cost, contains sufficient access from a major road and is within the Town's boundaries. The projected 25 year growth requirement of 92 lots could therefore be accommodated in the area north of North Road (Pg. 21)"
- c. Replace the text under the subheading Alignment with the Town of Trochu Municipal Development Plan with the following:
"The Town's MDP Bylaw MDP Bylaw 2023-05 serves as a general guide to facilitate the orderly development of land use, density of development, and location of major roads and facilities in the Town. The lands within the Northwest ASP are identified in the MDP as a Priority Growth Area for future commercial and residential development, including park and open space and the development of a senior's assisted living facility."
6. Under the heading 1.5 PLAN AREA, delete the following sentence from the second paragraph:

- a. The third bullet is replaced with the following:
"A 10.0 m right-of-way (URW 2411933) that accomodates a pipeline runs diagonally north/south through the Plan Area. This pipeline is a significant constraint for road crossings and development unless the pipeline is relocated by ATCO and the existing pipeline be abandoned and removed."
- b. A new fourth and fifth bullet are added in accordance with the following:

- c. The last bullet in the list is replaced with the following:
"Also within URW 801 1422, a private lease road runs along the eastern boundary of the Plan Area, servicing an oil and gas well located outside of the Plan Area that is undergoing remediation. When the well is remediated, this road may be retained by the Town to provide emergency response and maintenance access to the Plan Area."
8. Under the heading 2.2 LAND USE CONCEPT:
- a. Under the subheading Purpose, delete the last sentence as follows:
"Table 1 provides a breakdown of land use areas and statistics".
- b. Delete Table 1: Land Use Concept.
- c. Policy 2.2.1 is replaced with the following:

- k. Under the subheading Seniors Housing the first paragraph is replaced with the following:
"The MDP projects gradual growth in the Town's population with a trend towards an aging population and small household sizes. The provision of a senior's housing facility in the Plan Area supports an aging in place scenario for future senior residents by providing units designed for independent living and assisted living. This development has been allocated 4.2 hectares (10.4 acres) of land. The development is centrally located in the Plan Area, connected by paths and the local road network to the adjacent recreational uses and the Town's services. The senior's housing facility is expected to be built as the first phase of development in the Plan Area."
1. Figure 3 Seniors Housing, Open Space and Pathways is replaced with the attached Schedule 'B'.
- m. A new subheading "Population Projections" is added after the Senior's Housing subheading, and before the Commercial subheading, with the following text and tables:
"The population projection for the Plan Area is shown in Tables 1 and 2. The total population projection for the residential areas is estimated based on the potential number of dwelling units in each of the areas identified in Figure 2. The Low Density area assumes 464 m2 per dwelling unit, the Low to Medium Density are assumes 366 m2
per dwelling unit, and the Medium Density area assumes 285 m2 per dwelling unit. The number of units was then multiplied by the average number of residents per dwelling in Trochu (2.2 residents per dwelling) and a 10% range was used to calculate the low and high population estimates.
The first phase of the senior's facility is anticipated to include approximately 80 units, with a future expansion of an additional 64 units. The population projection for the senior's facility includes a mix of studio, single and two bedroom units."
