Prior to the issuance of a Building Permit, for any Conditional or Allowed Use, the Planning Department must review the proposed plans for compliance with Architectural Review, Chapter 15-5.

As part of a Master Planned Development, or a subdivision, the Planning Commission may designate maximum house sizes to ensure Compatibility. An Owner may combine Lots with designated maximum house sizes and achieve approximately 150% of the maximum house size attributed to a particular Lot. The Owner must request an increase in maximum house size prior to or concurrent with, the Lot combination plat. The request must be made on forms provided by the Planning Department for review by the Planning Director for compliance with the following:

1. HOUSE SIZE. The maximum house size may not exceed 150 percent (150%) of the house size allowed on each single Lot when those maximums are combined and averaged. The following formula must be used to calculate the maximum house size (MHS):
   
   MHS =((hsLot1 + hsLot 2...hsLotn) ÷n)x 1.50
   
   *where n is the number of Lots being combined, and hsLot1, hsLot2, hsLotn are the allowed house sizes in square feet, for the individual Lots in the Lot combination.
   
   For example: if two (2) Lots, one with a 4000 square foot maximum house and one with a 3000 square foot maximum, are combined the maximum house size would be 5250 square feet. The average of the two Lots is 3500 square feet. 3500 x 150% = 5250 square feet, i.e.
   
   ((4000 + 3000)÷2) x 1.5 = 5250 sq. ft.
   
   In Subdivisions where maximum house size is not specified, the house size on combined Lots must be determined by the Planning Director based upon neighborhood Compatibility, Lot size, visibility from Public Streets, and visual analysis.
   
2. SETBACKS. The allowed minimum Setbacks (MSB) for the proposed house size (PHS) on combined Lots must increase in proportion to the percentage of increase in the house size (%IHS) over the average maximum house size (AMHS) for the Lots being combined, according to the following formulas:
   
   %IHS = ((PHS-AMHS) ÷ AMHS) x 100
   
   MSB=Zone Setback +(Zone Setback x %IHS)
   
   For example: Using the previous example, where two Lots, one with a 4,000 sq. ft. maximum house size and one with a 3,000 sq. ft. maximum, are combined yielding a proposed house size (PHS) of 5,250 sq. ft., the percent increase in house size (%IHS) is fifty percent (50%).
   
   %IHS = ((5,250-3,500) ÷ 3,500) x 100 = 50%
   
   If the increased house size (%IHS) is fifty percent (50%) greater than the average maximum house size (AMHS) on any of the Lots being combined, the allowed minimum Setbacks (AMSB) must be fifty percent (50%) greater than the standard Setbacks of the zone.
   
   For example: If the zone Setback for Side Yards is twelve feet (12') and the percent increase in house size is fifty percent (50%) then the minimum Setback for the combined Lot is eighteen feet (18'), as follows:
   
   MSB =12' + (12'X50%) = 18'
   
   Therefore: Minimum Setback (Side) = 12' + (12' X 50%) = 18' if zone Setback is 12'.
   
   

   Lots with unusual configurations, topography, Access, or Significant Vegetation may have the Setbacks shifted upon approval of the Planning Director but in no case may they be less than the required Setbacks.

3. EASEMENT VACATIONS. If an easement must be vacated to allow construction on a combined Lot, the Applicant must show evidence that the easement can be vacated or relocated without affecting service to the adjacent Lots. The easement relocation agreement must be recorded and/or shown on the plat amendment for the Lot combination.
4. PLAT AMENDMENT. The Lots must be legally combined through plat amendment or administrative approval as provided in LMC Chapter 15-7, Subdivisions.

A Bed and Breakfast Inn is a Conditional Use. No Conditional Use Permit may be issued unless the following criteria are met:

1. If the Use is in a Historic Structure, the Applicant will make every attempt to rehabilitate the Historic portion of the Structure.
   
2. The Structure has at least two (2) rentable rooms. The maximum number of rooms will be determined by the Applicant's ability to mitigate neighborhood impacts.
   
3. In a Historic Structure, the size and configuration of the rooms are Compatible with the Historic character of the Building and neighborhood.
   
4. The rooms are available for Nightly Rental only. 
   
5. An Owner/manager is living on-Site, or in Historic Structures there must be twenty-four (24) hour on-Site management and check-in.
   
6. Food service is for the benefit of overnight guests only. 
   
7. No Kitchen is permitted within rental rooms.
   
8. Parking on-Site is required at a rate of one (1) space per rentable room. The Planning Commission may waive the parking requirement for Historic Structures if the Applicant proves that:
   
   1. no on-Site parking is possible without compromising the Historic Structure or Site, including removal of existing Significant Vegetation and all alternatives for proximate parking have been explored and exhausted; and
      
   2. the Structure is not economically feasible to restore or maintain without the adaptive Use.
      
9. The Use complies with Section 15-1-10, Conditional Use review.

Outdoor events and music require an Administrative Conditional Use permit. The Use must also comply with Section 15-1-10, Conditional Use review. An Applicant must submit a Site plan and written description of the event, addressing the following:

1. Notification of adjacent property Owners.
   
2. No violation of the City Noise Ordinance, Title 6.
   
3. Impacts on adjacent Residential Uses.
   
4. Proposed plans for music, lighting, Structures, electrical, signs, etc.
   
5. Parking demand and impacts on neighboring Properties.
   
6. Duration and hours of operation.
   
7. Impacts on emergency Access and circulation.

The raising and grazing of horses may be approved as a Conditional Use by the Planning Commission. In making a determination whether raising and grazing of horses is appropriate, the Planning Commission shall consider the following criteria:

1. Any barn must be located a minimum of seventy-five feet (75') from the nearest neighboring Dwelling Unit.
   
2. There shall be a maximum of two (2) horses per acre.
   
3. Terrain and Slope of the Property must be suitable for horses.
   
4. The Applicant must submit an Animal Management Plan outlining the following:
   
   1. waste removal/odors;
      
   2. drainage and runoff;
      
   3. bedding materials;
      
   4. flies; and
      
   5. feed/hay

Significant Vegetation includes large trees six inches (6") in diameter or greater measured four and one-half feet (4½') above the ground, groves of smaller trees, or clumps of oak and maple covering an Area fifty square feet (50 sq. ft.) or more measured at the drip line. 

Development plans must show all Significant Vegetation within twenty feet (20') of a proposed Development. The Property Owner must demonstrate the health and viability of all large trees through a certified arborist. The Planning Director shall determine the Limits of Disturbance and may require mitigation for loss of Significant Vegetation consistent with Landscape Criteria in Sections 15-3-3 and 15-5-5(N), and Title 14.
