Severance City Zoning Code

ARTICLE 4

Agreements, Dedications, and Construction Standards

Sec. 16.4.40. - Subdivision and site access requirements.

(a)

Major subdivisions.

(1)

Major subdivisions are required to provide at least two (2) fully functioning points of vehicular and pedestrian access to the public road network. These access points must connect to two (2) separate public roads to ensure adequate traffic circulation, emergency ingress and egress, and community connectivity. Sites with physical constraints or unique conditions may require a detailed analysis to determine if an alternative configuration can meet the intent of this requirement, subject to approval by the Town.

(2)

Subdivisions containing more than one hundred (100) residential units may be required to provide a third point of access to distribute traffic more evenly, enhance overall connectivity, and mitigate potential congestion at subdivision entrances. The need for additional access points will be determined based on the size, layout, and anticipated traffic impacts of the development, in consultation with the Town and emergency service providers.

(b)

Multi-family and commercial developments.

(1)

Multi-family developments and commercial site areas are required to provide a minimum of two (2) fully functioning points of vehicular and pedestrian access to the public road network. The distance between access points must be sufficient to reduce congestion and provide redundancy for emergency ingress and egress, as determined by the Town's adopted driveway spacing standards.

(2)

Where physical constraints or other unique site conditions limit the ability to provide two (2) public access points, developers must include an alternative plan for emergency vehicle access. This may involve the design and implementation of dedicated emergency routes, approved by the Town and emergency service providers, that meet all applicable width, surface, and clearance requirements.

(Ord. No. 2025-03, § 1)

Sec. 16.4.110. - Purpose.

When public improvements, dedications, or similar components are part of a development application, the applicant shall enter into a development agreement with the Town to guarantee timing of dedications and construction of all required public improvements shown in the final development plan(s), together with security in a form approved by the Town.

(b)

Step 2: The applicant returns the draft agreement with proposed revisions for final review and consideration by the Town.

(c)

Step 3: The Town sends the applicant a final signature ready version of the agreement to execute prior to final review and action on the development proposal. The signed agreement accompanies the final development plan for review by the decision body, as outlined in Article 2 of this Code.

(d)

Step 4: If the development plan is approved by the Town, the Town will execute the final development application and send the applicant a signed copy.

(e)

Step 5: The applicant shall post security, in a form approved by the Town Attorney and outlined in the executed development agreement, to cover the construction and warranty period of the necessary improvements outlined in the agreement.

(f)

Step 6: Following installation of the required improvements, the applicant shall apply to the Town for inspection of improvements, as required by this Code and all applicable laws, rules, and regulations.

(g)

Step 7: The Town shall complete inspection(s) of all required improvements and determine if the project has received initial acceptance and can move into the warranty phase.

(1)

If incomplete, the Town will issue the applicant a letter and list of defects or items that require additional attention prior to the Town issuing initial acceptance. Once the applicant has addressed the Town's comments, they shall apply for reinspection of the outstanding improvements, see Step 6.

(2)

If complete, proceed to Step 8.

(h)

Step 8: If deemed complete, the Town will issue initial acceptance of the required improvements and reduce the applicant's posted security to cover the two-year warranty period.

(i)

Step 9: Following the two-year warranty period, the applicant shall apply to the Town for final acceptance and release of the remaining security.

(j)

Step 10: The Town shall complete final acceptance warranty inspection(s) of all required improvements and determine if the project requires warranty work or if the Town can issue final acceptance.

(1)

If warranty work is needed, the Town will issue the applicant a letter and list of defects or items that require additional attention prior to the Town issuing final acceptance. Once the applicant has addressed the Town's comments, they shall apply for reinspection of the warranty items, see Step 9.

(2)

If no warranty work is identified, proceed to Step 11.

(k)

Step 11: If no warranty work is necessary, the Town will issue final acceptance of the required improvements and return the remaining warranty security held by the Town. At this point, all remaining obligations of the applicant should have been met, subject to the requirements of the final development agreement.

It must discuss the impacts on any existing floodways and/or floodplains both on and adjacent to the site as well as any FEMA applications required.

(3)

It must discuss previously submitted drainage studies for the site or project and their influence on the proposed stormwater facility design, and if applicable, the stormwater master plan, how recommendations in the stormwater master plan affect the stormwater facility design for the site, and how the proposed stormwater facility design complies with the stormwater master plan.

(4)

It must provide sufficient information for an initial assessment of whether the proposed stormwater facility design can safely convey stormwater runoff through the development to an adequate stormwater system and accessible point of disposal with sufficient system capacity to carry necessary flow of the proposed development without overflowing downstream channels and existing storm drainage facilities or causing damage to property.

Water and sewer utility plan and report prepared by a registered professional engineer. It is necessary that the engineer consult with the appropriate utility service providers regarding the design of all utilities through the proposed development.

(1)

It must discuss the projected total water needs of the development for domestic consumption and fire protection, including without limitation, data on projected annual usage (GPY), average day demand (GPM/GPD), and maximum day demand (GPM/GPD), peak hour flow (GPM), as well as the projected total flow of sewage through a treatment plant expected to be generated by the proposed development.

(2)

It must discuss previous water and sewer studies for the site or project and their influence on the proposed design for water and sewer facilities, and if applicable, the water, sewer, and/or non-potable water master plans, how recommendations in the water, sewer, and/or non-potable water master plans affect the proposed water and sewer improvements for the site, and how the proposed water and sewer improvements for the site comply with the water, sewer, and/or non-potable water master plans.

(3)

If located within the boundaries of the Town's water, non-potable water, or sewer utility enterprise respective service areas, it must also provide sufficient information for an initial assessment of the proposed development's impact on all parts of the Town's sanitary sewage collection system (including without limitation laterals, interceptors, lift stations, treatment plants, points of discharge), potable and/or non-potable water systems (including without limitation water source, water quality, treatment, storage, pumping facilities, and metering devices), as well as an evaluation of the adequacy of the Town's water, non-potable water, and/or sewer (where applicable) utility enterprises, respectively, to serve the proposed development together with existing development and development which is reasonably probable of connecting to the applicable Town utility system (e.g., legal buildable lots in approved subdivisions for which building permits have not been issued).
