b. When the application is found to meet the requirements of this title or could meet the requirements with specific conditions imposed, and all comments have been received from those to whom a request to review was made, the community development director or designee shall cause the application to be forwarded to the designated land use authority for approval. The designated land use authority for preliminary plats shall be the planning commission. Staff shall notify the developer of the date, time, and place of any public meeting at which the application shall be reviewed by the planning commission.

c. The planning commission shall approve a preliminary plat which it finds to be in compliance with the standards and criteria set forth by the city in this title and all other laws, ordinances, plans, and policies of the city and state. When not all criteria are met, the planning commission may conditionally approve a preliminary plat, imposing such conditions as it may require in order to bring the project into compliance with the requirements of state law, or the city’s ordinances, plans, and policies.

d. Upon approval of the preliminary plat including the approval of the partial infrastructure improvement plans as required, a mass grading permit may be issued which allows the developer to begin site work at their own risk, prior to final approval. Issuance of a grading permit prior to final plat or final site plan approval does not constitute a vesting of development rights.

e. Preliminary approval of a subdivision with partial infrastructure improvement plans shall be valid for not more than eighteen (18) months from the date of approval by the land use authority. A letter documenting the approval, the date of the approval, and any conditions of approval shall be provided by the community development director or designee to the applicant within ten (10) business days of the approval.

f. If it is determined by the community development director that substantial progress toward completion of the final subdivision plat has been done, and the final plat cannot be timely approved due to reasons beyond the control of the developer or for other good cause, the community development director may agree to a single reasonable extension of time to complete the final subdivision plat and all infrastructure improvement plans for a period of time not to exceed six (6) months.

g. Approval of the preliminary plat or preliminary site plan does not constitute full approval of the development nor vest any development rights as additional requirements may be imposed that are a result of more detailed and thorough review of all plans, specifications, reports, investigations, etc. (Ord. 2019-10-002, 10-10-2019; amd.
