There are (4) townhouses per building and each building has a proposed foot print of 4,622 square feet (18,488 square feet total combined/proposed foot print). The proposed max structure height is 35’-0”. Maximum structure height will also conform to the one-foot horizontal distance for every foot in foot in building height measured at the eve side of building nearest to the property line. Occupants: 110 maximum occupants are estimated based on habitable floor area and 200 square feet per occupant. Garage areas have been excluded from the occupant calculations. Deliveries: Deliveries are estimated at one delivery per unit or 16 deliveries per day. Buffering: Landscape Plan L101 addresses buffering between adjacent single-family, multi- family, and commercial uses. Trees and shrubs are proposed on all 4 sides of the overall development and a 6’ high privacy fence is included along the north, east, and west development boundaries. Traffic, Circulation, and Parking: Utilize the existing WYDOT Permit for Clearview Drive. Refer to SP101 for trip generation figures. Two-way circulation has been provided within the development and all townhouses have either one or two car garages in addition to driveway parking. Refer to SP101 for required and proposed parking figures. Paved driveways and circulation routes are included to mitigate dust. Water and Sewer: The project will have two phases. Phase one is to construct (1) four unit building on each lot for a total of 8 townhouses. Phase two is to construct (1) additional four unit building on each lot for a total of 16 townhouses. In order to construct phase two, UIC permitting is required. Sunrise Engineering has reviewed this approach with Mark Baron at DEQ and reviewed distances to public/private wells. Refer to exhibits A and B at the end of this document for additional well information. Regarding water, the Etna Water board has agreed to issue (8) 3/4” taps during their regularly scheduled meetings and a letter of intent to serve will be requested at the January meeting. Preliminary Fire Review: Drawings have been sent to Jeff Schoen at the WY State Fire Marshal’s office for comments. Snow Storage: Refer to drawing GP and SP101 for snow storage locations and percentages. Drainage: In conjunction with the general east to west flow, the area between the buildings A-2 and B-1 will be graded to drain southward. This area is grassy so there will be significant infiltration and any remaining water will flow to the western detention basin. The on-site road and parking areas will drain to the grass between the driveways with any overflow going southward into the detention basins on the west side of the driveway entrances. Usable Open Space: All townhomes have access to rear yard areas and are provided with covered decks. Buildings A-2 and B-1 share a larger combined rear yard area for group activities. Location of Use: All surrounding properties within a 300’ radius are within the Etna Mixed Zoning area: See Image Below. Thank you for reviewing our proposed sketch plan submittal.
