Mountain Village City Zoning Code

17.3.11 Building

Height.

A. General. The Town requires a Building Height and an Average Building Height calculation. The building height requirements of this section shall apply unless other building heights are specified in an approved PUD development agreement or on a recorded plat.

1. The Building Height shall be measured from the highest point on the rooftop, roof ridge, parapet, or topmost portion of the structure (including but not limited to the roofing membrane) to the natural grade or finished grade, whichever is more restrictive, located directly below the highest point of the structure. A building height calculation is produced for each of the four (4) architectural elevations.

2. On complex buildings with multiple heights and/or buildings with multiple heights on sloping sites, the building height shall also be demonstrated relative to a plane parallel to and measured vertically from the natural grade or finished grade, whichever is most restrictive, to the maximum building heights established in Table 3-3 of the CDC. No portion of the building may exceed this parallel plane or slope except as otherwise permitted within the CDC. See Figure 3-2-5 below.

3. If the existing pre-construction grade has been disturbed prior to development, the Director of Community Development may accept an estimation of pre-development topography prepared by a registered land surveyor or civil engineer. The Director may require additional historical documentation, technical studies, reports or other information to establish the natural grade.

4. If the Planning Division determines that there are minor irregularities in the natural grade, these areas shall not be used in determining compliance with the building height limitation set forth herein, and the surrounding typical natural grade shall be used.

5. Window wells and similar building appurtenances installed below grade that extend out five (5) feet or less (as measured from the outside of retaining wall) shall not be counted as the finished grade for the purposes of calculating building height if such features do not add to the perceived height of a building.

1. The Average Building Height shall be measured from the natural grade or the finished grade, whichever is more restrictive, to the point on the roof plane midway between the eave and the highest point on the rooftop, roof ridge, parapet or topmost portion of the structure. An average building height calculation is produced for each of the four (4) architectural elevations. The four (4) height calculations are then averaged to derive the Average Building Height.

2. On complex buildings with multiple heights and/or buildings with multiple heights on sloping sites, the average building height calculation shall be determined by taking the average of heights at equal intervals around the perimeter of a building. Those intervals shall be no more than twenty (20) feet. When multiple roofs occur within any interval, the height for that interval shall be measured from the finished grade or natural grade (whichever is most restrictive) to the highest point on the rooftop, roof ridge, parapet or topmost portion of the structure. For purposes of determining the maximum average height on complex buildings, a roof shall have a horizontal projection of at least ten (10) feet. This definition does not intend to allow strategies to circumvent the intention of the maximum average height limitation through such relationships as high-rise structures surrounded by low secondary roofs.

1. All development applications subject to the building height limits established by this CDC shall submit the following information to ensure the requirements set forth herein are met:

a. A certified topographic survey of the building site with one (1) or two (2) foot contour intervals in a United States Geological Survey (“USGS”) datum prepared by a Colorado public land surveyor. Such survey shall be prepared to ensure that the Town can certify elevations, floorplans and overall height based on reliable site plan datum. The USGS datum shall be indicated as a note on the topographic survey stating what datum was used and how it was derived.

b. Notwithstanding the foregoing, the Planning Division may waive the submission of existing topographic data if a proposed building is:

i. Located on slopes that are ten percent (10%) or less; and,

ii. The proposed building or structure and any associated roof appendages are not within five (5) feet of the maximum height allowed by the underlying zoning district.

c. A site plan of the building site that shows the following information with a maximum scale of one (1) inch equals thirty (30) feet:

i. Natural grade in a dashed line;

ii. Finished grade in a solid line;

iii. The building height measurement points that show the USGS elevations of the existing and finished grades where the building height and the average building height are proposed to be measured;

iv. Outline of the building façade including the exterior wall assembly;

v. Outline of the roof dripline and the corresponding mean sea elevation for all horizontal eaves in a USGS datum;

vi. A roof plan showing roof ridgelines and the corresponding mean sea level elevations in a USGS datum; and

vii. The roof appendages and the corresponding mean sea level elevations in a USGS datum.

d. Elevation drawings of all facades of a proposed building or structure that show:

i. The maximum roof or structure height in mean sea level elevation in a USGS datum based on the certified topographic survey datum as specified above;

ii. The natural grade of the site in a dashed line;

iii. The finished grade of the site in a solid line; and

iv. The ridgeline elevations in mean sea elevation; and

v. Parallel Plane or Slope Analysis as applicable.
