A. Pre-application Meeting:
1. Intent: The purpose of a pre-application meeting is to allow the applicant the opportunity to share proposed project plans with the ALUA. It also allows the ALUA to share thoughts and ideas with the applicant regarding the proposed plans.
2. The city recommends that a pre-application meeting is held as a course of procedure. However, a pre-application meeting is optional and cannot be mandated. If requested, a pre-application meeting shall be held within 5 business days of an applicant request.
3. If an applicant requests that a pre-application meeting is held, the ALUA will comment on the compatibility of the proposed development with the general plan, the zoning ordinance, this title, and other ordinances and/or city regulations and policies.
B. Preliminary Subdivision Application Approval: The planning commission shall act as the ALUA that receives, reviews, considers and issues its approval of preliminary plat applications. It is charged with making investigations, reports and recommendations on proposed subdivisions as to their conformance to the general plan and zoning ordinance, and other pertinent ordinances, regulations, documents, standards and requirements. After reviewing the preliminary plat and determining that it meets all the applicable preliminary requirements and standards, the planning commission may approve, approve with conditions, or disapprove of the preliminary plat to the DRC.
C. The planning commission shall review the preliminary plat and may visit the site of the proposed subdivision if deemed appropriate. The applicant must submit the application within sixteen (16) business days prior to a scheduled planning commission meeting. The planning commission must review the subdivision application within thirty (30) business days from the date a complete application has been received. (1-2025, 3-18-25)
D. The planning commission will discuss the application and the findings of their review during a regularly scheduled planning commission meeting, which may
include a single public hearing to receive public comment, although a public hearing is not required and is not recommended.

d. A signed statement shall be provided for decision by the ALUA from each of the utility companies involved, stating that they have reviewed the plat, that they approve the plat as it relates to their company, that they agree with placing all of their utilities underground within the rights-of-way or utility easements as shown on the plans and are willing to provide the needed service for the development. The signed statements shall also include descriptions of any restrictions that will be imposed by the utility companies, any fees that will be assessed by the utility companies to install the utilities and any timetables that the utility companies might use to install their respective utilities.

d. The location, width, and names of all existing streets within two hundred feet (200') of the subdivision and of all prior platted streets or other public ways, railroad and utility rights of way, parks, and other public open spaces, permanent easements and section and corporation lines within and adjacent to the tract.

a. Intent: The purpose of having a site analysis map completed is to better understand what parts of the land are buildable, what must be left alone, and what features the community may want to preserve.
b. Process: The applicant prepares a site analysis map of the property of the proposed project site. The site analysis map shall be prepared in a digital pdf format and shall include all existing resources, including, but not limited to:
(1) A contour map (request for these maps can be made from the U.S. Geological Survey [USGS]).
(2) A map showing soil types (requests for these maps can be made through the Soil Conservation Service [SCS]).

(6) Historical sites and buildings.
(7) Cultural features.

(10) Unusual rock formations.
(11) Any other features that make the property distinctive. (See title 10, chapter 11 of this code for additional information.)
4. Site Visit:
a. Intent: Seeing the property and its features will aid in understanding the dimensions and elements of the property. Important features may be very different than they appear on paper; not all natural resources are alike or have the same value. Before the ALUA agrees to modifications of the property, they should know the full impact on the surrounding area.
b. Process: Once the preliminary plat has been submitted, the ALUA may decide to visit the site. If a site visit is held, the applicant will be invited to join. The results of the site visit used to help to determine whether the preliminary application complies with applicable local regulations, and whether it shall be approved and proceed for final subdivision review.
5. Proposed Plan: The preliminary plat shall also show all appropriate and pertinent information required to facilitate a thorough review process. At a minimum, the following shall be shown:
a. The layout of the streets, showing location, widths, and other dimensions of proposed streets (designated by actual or proposed names and numbers), crosswalks, alleys, and easements.
b. The layout, numbers, and typical dimensions of lots.
c. Parcels of land intended to be dedicated or temporarily reserved for public use or set aside for use by property owners in the subdivision.
d. Building setback lines as required by code.

h. Typical street cross sections and grades of streets where required by code.
i. A tentative plan or method by which the applicant proposes to handle storm water drainage for the subdivision.
j. Where necessary, copies of any agreements with adjacent property owners relevant to the proposed subdivision. Said agreements shall be presented to the ALUA at the time of preliminary plat submission.
G. If the preliminary application complies with applicable local regulations, it shall be approved and proceed to final subdivision review. The ALUA shall return one signed copy of the plat to the applicant with any conditions attached. Other signed copies shall be forwarded to each of the interested city departments. The ALUA shall retain one signed copy of the plat for its files.
H. If the preliminary plat is rejected, the ALUA shall return a signed copy of the plat bearing the reason for the rejection.
I.
The receipt of a signed copy of the approved preliminary plat shall authorize the
applicant to proceed with the preparation of the final plat and construction
documents. In the event a final plat is not submitted for at least one phase of the
proposed subdivision within twelve (12) months following approval of the
preliminary plat, such prior approvals shall be void and the applicant shall again
be required to submit a sketch plan as per this title. When a subdivision is
developed in phases, the final plat for a second phase and any subsequent phases
must be submitted for approval within two years of the previous phase approval,
or as extended by the city council. If a second phase and any subsequent phases
are not submitted within two years of the previous phase approval, the preliminary plat and sketch plan approval for all phases not submitted shall be void.
