Chapter 176.28

176.28    CLUSTER DEVELOPMENT OPTION.  The intent of the Cluster Development Option is to promote greater design flexibility in land development by offering density transfers in conjunction with relaxation of conventional lot and building bulk controls.  In those zoning districts offering the Cluster Development Option, the developer has the option of choosing either conventional or cluster development.  The Cluster Development option is intended to promote the most appropriate design and development of land, facilitate the adequate and economic provision of public services, and preserve the natural and scenic qualities of open areas.

1.                  General Requirements.  Whenever there is a conflict or difference between the provisions of this section and those of the other sections of this Zoning Ordinance, the provisions of this section shall prevail.  Subjects not covered by this section shall be governed by the respective provisions found elsewhere in this Ordinance.  Cluster development shall conform to the following:

A.                 In a district in which the Cluster Development Option is available, dwelling units may be clustered in one or more locations upon the site, provided that the average land area for which dwelling unit contained in the site, exclusive of the area occupied by private streets or public rights-of-way, shall not be less than the lot area per dwelling unit required in the zoning district within which the development is located.

B.                 Single-family dwellings, two-family dwellings, three- and four-plexes, multiple-family dwellings, and accessory uses may be permitted in a cluster development, provided that the density requirement set forth in paragraph A above is met.  However, no use shall be permitted except in conformity with an approved Cluster Development Plan pursuant to the provisions set forth herein.

C.                 Other principal permitted uses in the zoning district within which the development is located may be permitted in the cluster development.  However, no use shall be permitted except in conformity with an approved Cluster Development Plan.

D.                 Conditional uses set forth in the zoning district within which the development is located may be permitted in the cluster development, when authorized by the Zoning Board of Adjustment as provided in Section 176.36.  However, no conditional use shall be permitted except in conformity with an approved Cluster Development Plan.

E.                  The cluster development may depart from strict conformance with the required lot dimension, lot area, lot width, setback, yard, and bulk regulations and the zoning district within which the development is located, so long as the development will not be detrimental to or endanger the public health, safety, morals, comfort, or general welfare.

(1)        However, the setbacks on all exterior boundaries of the cluster development shall be at least equal in width or depth to that required in the adjacent property.

(2)        No departure from conformance with the lot dimension, lot area, lot width, setback, yard, and bulk regulations shall be permitted except in conformity with an approved Cluster Development Plan pursuant to the provisions set forth herein.

F.                  Adequate off-street parking and loading facilities shall be provided and shall conform to the standards set forth in Section 176.29 of this Ordinance.

G.                 Adequate provision shall be made to provide ingress and egress designed to promote optimal traffic safety and flow.

H.                 If the sequence of construction of various portions of the cluster development is to occur in stages, then the off-street parking, open space, or any other shared facility as contained in the approved Cluster Development Plan shall be developed in proportion to the number of dwelling units developed during the given stage of construction.

I.                    At no time during the construction of the cluster development shall the number of constructed dwelling units exceed the over-all density per acre established in the approved Cluster Development Plan.

J.                   No land may be used or building permit issued on land within the cluster development until all procedural and regulatory provisions of this section have been complied with.

2.                  Coordination With Subdivision Ordinance.

A.                 No lot, tract, parcel, or other division of land may be divided into two or more lots, tracts, parcels or other divisions of land for the purpose of sale, transfer or of building development, whether immediate or future, including the re-subdivision or re-platting of lands or lots, except in conformance with Chapter 175 (Subdivision Regulations) of this Code of Ordinances.

B.                 It is the intent of this section that subdivision plat review, when applicable, be carried out simultaneously with the review of the Cluster Development Plan.

C.                 The Cluster Development Plan required under this section may be submitted in a form which satisfies the subdivision filing requirements set forth in said Chapter 175, provided that such Cluster Development Plan satisfies all the requirements set forth in this Ordinance.

3.                  Filing Procedure.

A.                 Application.  A petition for a cluster development shall be submitted to the Clerk accompanied by thirty (30) copies of the Cluster Development Plan and, when appropriate, subdivision plat.

B.                 Filing Fee.  The filing fee for a cluster development shall be $5.00 per acre or fraction thereof with a minimum fee of $40.00.  If a Cluster Development Plan is submitted in conjunction with a subdivision plat, the applicant shall pay either the cluster development filing fee or the plat filing fee, whichever amount is greater.  The filing fee is not refundable.

C.                 Cluster Development Plan.  The Cluster Development Plan shall contain the following information:
