The intent of this district is to preserve and establish peaceful low-density neighborhoods in which owner-occupied single-family structures are the dominant form of dwelling unit. This district is intended to provide a minimum density of three units per acre and maximum of six units per acre to promote the efficient use of land within the Grand Mound urban growth area. This district will allow infilling with a variety of housing types and at a relatively low urban density to maintain the existing character of the Grand Mound community.

(Ord. 11398 § 3 (part), 1997: Ord. 11220 § 1 (part), 1996)

(Ord. 12761 § 15, 2002; Ord. 11804 § 60, 1998; Ord. 11398 § 3 (part), 1997: Ord. 11220 § 1 (part), 1996; Ord. No. 15355, 1(Att. A, § Z), 10-18-2016)

(Ord. No. 16332, § 2(Att. A, § I), 12-12-2023)

1.

For any land division that is submitted in phases of development, and for any development where sewer is not available, the approval of each phase of development shall be contingent upon the following:

a.

The lots created by the land division for residential and associated uses (e.g., dwelling units; private recreation areas; stormwater detention, treatment and infiltration) shall meet all of the requirements of Section 20.15.050.

b.

A conversion plan must be submitted for the remaining portion of the site reserved for future phases of development (i.e., reserve tract) which demonstrates that the reserve tract can be subsequently subdivided to create sufficient lots to achieve the minimum densities necessary to comply with Section 20.15.050. Such conversion plan shall depict a schematic lot layout, approximate location of utility easements, and potential street access and an internal circulation system consistent with county transportation policies. Conversion plans shall not be required to be stamped by an engineer or surveyor, and may be included as part of a drawing or plan submitted for the land division application. Simultaneous with the filing of the conversion plan, the applicant will be required to record with the county auditor, in a form acceptable to the prosecuting attorney, a document to be placed in the chain of title of the property giving constructive notice of the special density requirements relating to the reserve tract. This conversion plan will not bind future phases of development of the site to anything except the obligation to meet the overall density requirements of the total tract. Acceptance of a conversion plan by the county does not, by itself, constitute approval of the granting of vested rights to a future phase of development. (Note: The purpose of the conversion plan is to ensure that the reserve tract can be ultimately developed at the residential densities required for this district, not to limit future development to a specified development scheme. Recognizing that some property subject to this requirement may not be redeveloped in the near future, the time and cost involved in preparing and obtaining approval of a conversion plan should be kept to a minimum.)

2.

A permit to construct any single-family dwelling on a lot of record that is greater than one acre in size shall be contingent on the submission of a conversion plan which demonstrates that the remainder of the lot may be subsequently subdivided to create sufficient lots to achieve the minimum densities necessary to comply with Section 20.15.050. Such conversion plan shall meet all of the provisions of subsection (1)(b) of this section.
