Sections:
19.34.020 Manufactured home parks – Establishment.
19.34.030 Manufactured home parks – Performance regulations.
19.34.040 Additional regulations.
19.34.010 Purpose.
The purpose of this chapter is to establish standards for the development of manufactured home parks (MHPs). Such standards are necessary to ensure the development of well-planned MHP facilities. (Ord. 09-14 § 4, 2014; Ord. 22-08 § 1 (Exh. A), 2008; Ord. 22-05 § 1, 2005; Ord. 40-97 § 7, 1997; Ord. 1020 § 8, 1981).
19.34.020 Manufactured home parks – Establishment.
Where permitted, manufactured home parks shall meet the following minimum requirements:
(1) When two to four manufactured homes are to be located on a lot or parcel, the applicant shall submit a site plan for staff review and approval. The site plan shall show compliance with all performance regulations established by this chapter.
(2) When five or more manufactured homes are to be located on a lot or parcel, such manufactured home parks shall be permitted only upon the issuance of a site plan review permit processed pursuant to Chapter 19.33 BMC. Plans and documents submitted as part of the site plan review application shall show compliance with all performance regulations established by this chapter and Chapter 19.33 BMC.
(3) MHP sites shall be 4,000 square feet (sf) for each single or double wide home; and 5,000 sf for each triple wide home.
(4) Subdividing MHP property is unnecessary if the MHP property remains the property of one person.
(5) Any applicant shall submit, along with the application, plans, drawings and other information sufficient to determine whether the manufactured home park complies with the performance standards contained in BMC 19.34.030. Each application shall include the following:
(a) Overall site development plan showing location of all manufactured home pads, buildings and uses, areas devoted to open space and buffering, ingress and egress points, and internal pedestrian and vehicular circulation. Such plans shall include at least the following:
(i) Location, width and typical cross-sections of internal circulation streets;
(ii) Location and size of all manufactured home pads, with patio and/or deck areas and percent of impervious surface coverage of the site;
(iii) Location and size of all parking and bulk storage areas;
(iv) Location and size of open space areas required by BMC 19.34.030(5);
(v) Existing and proposed topography at contour intervals of no more than two feet;
(b) Storm drainage report complying with Chapter 14.30 BMC;
(c) General landscape plans showing location of buffers and open spaces. Detailed landscape plans must be submitted to, and approved by, the decision maker prior to initial site work.
(6) Improvements required by the approved site plan shall be completed or bonded as required by this code. Failure to comply with the requirements of the decision maker and/or the official site plan shall be sufficient grounds to revoke the site plan review permit. (Ord. 09-14 § 4, 2014; Ord. 01-12 § 23, 2012; Ord. 22-08 § 1 (Exh. A), 2008; Ord. 22-05 § 1, 2005; Ord. 40-97 § 8, 1997; Ord. 1020 § 8, 1981).
19.34.030 Manufactured home parks – Performance regulations.
The performance criteria set forth in this section shall be minimum criteria.

(2) Circulation System.
(a) All interior MHP streets or drives shall be private.
(b) The proposed MHP streets shall be constructed within an easement that extends at least two feet beyond the paved surface and shall be at least 30 feet in width.
