Construction drawings - development
The design and approval of public infrastructure, such as utilities, roads, and other surface improvements, is managed through the construction drawing design review process. The construction drawing approval process is a major step towards achieving permission for the construction of both underground utilities (water, sanitary, and storm mains) and surface improvements (roadways, sidewalks, pathways, and surface drainage).
Types of construction drawing submissions
- Onsite – Required for the development of a Subdivision Phase in a community; shows the infrastructure designed to make each parcel serviceable and the subdivision functional.
- Offsite – Infrastructure that connects the subdivision services to utilities and may be required to make Onsite operational.
- Ponds – Required for storm water management within a community. Alberta Environment approval required.
- Main Extension – Required to extend infrastructure a short distance, commonly associated with a Development Site Servicing Plan (DSSP).
- Landscape Construction Drawings – Required when the development includes or affects adjacent Reserve land (MR, MSR, ER) and Public Utility Lots (PUL, Storm Pond), or includes Road cross sections that include street trees. Please refer to Park development guidelines for landscape construction specifications.
To submit construction drawings and permission to construct requests, applicants must become a registered user to log onto VISTA and have a valid Business ID number. To request an account and Business ID, visit calgary.ca/vista.

Top reasons for circulation delays
- Not adhering to the current CAD standard.
- Incomplete application submission including the omission of updated adjacent/adjoining block profiles.
- The detailed cover letter is not explicit enough to clarify complexities.
What makes a smooth circulation
- A comprehensive detailed cover letter. At the preliminary submission, outline the project scope and justifications and explanations of any unusual conditions. All subsequent submissions should clearly and thoroughly address the comments from the review.
- Providing a CPC approved and stamped Outline Plan within the drawing set.
Construction drawings can be in circulation for approximately 6 weeks to complete a thorough design review, depending on the complexity of the project. Reviews by specialists occur simultaneously and by Generalists, successively.

Permission to construct
The objective of the review and approval of the infrastructure design, such as utilities, roads and other surface improvements, is the issuance of the permission to construct. A request to construct may be submitted at any time during the construction drawing review process.
Types of Construction Requests
- Underground Infrastructure – full or partial, or remainder
- Surface Infrastructure – full or partial, or remainder
Permission to construct is granted when the following requirements have been met
- Design approval has been achieved.
- A financial agreement is in place.
- For underground permission, an approved Erosion & Sediment Control Report and, for Storm Ponds, authorization from Alberta Environment.
- For surface permission, an approved Pavement Design from Roads, Construction, Material and Research and an approved Storm Water Management Report.
*Each request must be submitted in one multi-page PDF document.
Top reasons for circulation delays
- An incomplete request.
- The Development Agreement or Indemnificatin Agreement number is unavailable due to outstanding requirements.
What makes a smooth circulation
- Clear site map(s) displaying the exact infrastructure requesting to be built. This may mean including multiple site maps depending on the extent of the proposed infrastructure to be constructed.
- Clear site map titles (ie. Underground Construction Permission Request or Partial Surface Construction Request).
- Requests for partial permisson to construct - indicate which area is being constructed with a red boundary, and hatch and label the area which is not included in the request.
Typically, the timeline to review each request to construct is 5 business days. It can take up to 3 business days to release the permission letter once the review is complete.
The following process is standard for construction requests:
- Public Infrastructure: Reviewed for completeness of request (CARL). The Infrastructure Strategist ensures the subdivision construction area is accurate.
- Development Engineering: Reviewed for compliance with and adherence to all prior to approval requirements and comments.
- Once both Public Infrastructure and Development Engineering are satisfied all requirements have been met, the permission letter is prepared and delivered.
Financial obligations for public infrastructure construction
A Development Agreement will be entered into between The City and a Land Developer. This legal contract is used for all residential, industrial and commercial developments. It sets out the terms and conditions under which development of the lands are to take place within The City including the responsibility to construct public infrastructure and associated financial obligations.
Tiering and Securities Framework
The City uses a ranking system that determines the securities amount required before construction begins. This framework provides a risk-managed approach to supporting new investment opportunities through easing securities requirements for developers who meet their performance requirements.
An Indemnification Agreement may be entered into between The City and a property owner and authorizes a certified contractor working on behalf of the property owner/ developer to excavate, break or reconstruct all or any portion of infrastructure for a project.
If unknown to you, The City will identify which agreement is applicable as part of your construction drawing submission.
Construction drawings supporting documents and reports
On an annual basis, The City of Calgary requires the Development Industry to provide information regarding proposed developments involving the extension or replacement of watermains, sanitary sewers and/or storm sewers.
The information collected will facilitate Alberta Environmental Protection and Enhancement Act (EPEA) applications and authorizations as well as assist various divisions within The City with forecasting capital projects and scheduling for the year.
Every proposed development must be reported to Calgary Approvals Coordination-Public Infrastructure who then applies to Alberta Environment and Parks (AEP) for authorization to proceed with construction of said developments.
Under AEP’s EPEA, The City of Calgary is the approving authority for these activities within its jurisdiction and is responsible for coordinating and integrating the review of potential impacts of proposed projects on the environment in The City of Calgary’s administrative region. See, Letter of Authorization (LOA) and project data sheet.
If a storm drainage system for a subdivision drains to a stormwater pond, a Pond Report must be submitted and approved by Water Resources-Development Approvals prior to submitting the infrastructure construction drawings to Calgary Approvals Coordination-Public Infrastructure. Stormwater management facilities must be constructed prior to, or in conjunction with, the first phase of development in the Outline Plan area.
The City of Calgary will coordinate the registration of public ponds under the Alberta Environmental Protection and Enhancement Act (EPEA) with Alberta Environment and Parks (AEP). The purpose of EPEA is to support and promote the protection, enhancement, and wise use of the environment, and is administered by AEP. A written authorization from AEP is required for the construction or modification of storm drainage treatment facilities, including stormwater ponds. Pond Submission and Approval Process (calgary.ca)
A Pond Report, approved The City (Water Resources), is required prior to Water Resources submitting the application for registration to AEP. The owner, developer, or designated consultant is responsible for preparing and submitting the required information to Water Resources including a completed EPEA application form.

Erosion and Sediment Control plan reviews are a parallel process to Construction Drawing reviews. Approval is required prior to approval of underground or surface construction.
Find guidelines, standards & specifications and the ESC Field Manual, refer to Erosion and Sediment Control Plan Reviews.
The City of Calgary requires that Geotechnical Reports be submitted as part of Land Development Applications to provide confirmation that the lands in question can physically accommodate the proposed development while minimizing Risks to Public Safety.
There are three main types of Geotechnical Reports that may be required as part of a Land Development Application.
They are defined as follows:
- Geotechnical Evaluation Report – An interpretative report that is completed by a qualified Geotechnical Engineering Consultant and is intended to evaluate the geotechnical conditions of the site and confirm that the land may be used safely for the intended use without undue risk of hazards.
- Slope Stability Report – A detailed report intended to assess Stable Land within the area set out in the report. This report is used to determine the boundaries of Development.
- Deep Fills Report – A geotechnical analysis of the soils within areas of the Development being filled more than two metres deep. The report contains recommendations on any Development restrictions, including bearing certificates and special foundation designs that may be necessary to provide integrity of any structure, including buildings, roads and utilities constructed on those fill areas. A Deep Fills Report will also typically contain a plan showing all areas of cuts and fills known as a Cut-Fill Plan.
Depending on the characteristics of the parcel, more than one type of Geotechnical Report may be required in connection with a given Land Development Application.
For more details, see Geotechnical Reports.
Plans must be created by the applicant or an Alberta Land Surveyor to show the boundaries of each new lot. Upon approval of a subdivision by plan, an Alberta Land Surveyor prepares a plan of survey, based on monuments placed in the ground. The plan gets registered at the Land Titles office.
Plans for corner cuts, road widening, access easements, utility rights-of-way, that have no concurrent subdivision applications.
A conceptual stormwater drainage plan in support of the Area Structure Plan and prepared for large drainage areas serviced by a single outfall to a receiving water body such as the Bow River.
For more information see Staged Master and Master Drainage Plans.
Required from the Province of Alberta prior to approval of Outline plans.
As part of the planning process in Calgary, residential areas are examined to determine whether there is an existing or potential problem in outdoor rear leisure areas around the home. The City is committed to reducing the impact of noise generated by vehicles in existing and future residential areas.
Related info: Network Planning.
An approved Pavement Design is required to obtain surface construction permission. The pavement design must be submitted, under cover letter by the developer or their consulting engineer, to The City of Calgary, Transportation, Roads, Materials & Research for approval. See Road specifications & guidelines for more information at Roads.
The objective of a Sanitary Servicing Study (SSS) is to demonstrate the adequacy of the existing and proposed sanitary sewer systems to satisfy the demands of a proposed development or redevelopment.
For more details, see refer to the Sanitary Servicing Study Guidelines
For more information on what to submit and to get additional support or to inquire about report availability, see Sanitary Servicing Studies.
