for a residential dwelling and pool and associated PD conditions.

the property was recommended for denial by the Planning and Zoning Commission.

ground floor and a room upstairs with a bathroom, this is located to the west of the

DISCUSSION: The current owners would like to make some improvements to their property in the form

Site Plan:
With this request the applicant is requesting to amend the existing Planned Development
to include all of the proposed new building as well as the existing the accessory building
constructed sometime around 2002/2003 by the previous owner, identified on the current
plans as a “carriage house” that was built on the property. This is a two-story building with
a garage on the ground floor and a room upstairs with a bathroom. This is located to the
west of the main house along the circular drive.
The majority of the new development will occur behind the existing house, backing up to
Denton Creek. The construction begins with an extension of the concrete slab at the rear
of the existing house and the addition of a covered porch area. The new covered open air
porch area will match the main house in color and will have a stone veneer. A built-in
grill, smoker and countertop with a sink is proposed. A new guest suite of 810 sf is
proposed to be located on the west side of the pool area. It is a one story building
approximately 18 feet in height to the roof peak. This building is proposed to contain a
guest bedroom and bathroom. This will not be rented out but available for visiting family.
The building also contains a pool bathroom (toilet, sink and shower) that is accessible only
from the outside. The building will be mostly of stone veneer with a cast stone band. The
roofing for all of the new construction will be a Tesla shingle roof.
To the east of the guest suite, a pool house (2,303 sf) with a kitchen is proposed. This
building is proposed to contain a cooktop area in an island, a sink, oven, refrigerator,
freezer and a large open area. This portion of the pool house is directly north of the pool
and opens up into a bar and game area to the east of the pool. The game area will include
a golf simulator area. Also, a pool storage room is part of this building, but only accessible

from the outside. The pool equipment will be located beside this area and screened with a
wooden fence. A concrete pad with a trellis of 9’7” in height is proposed between the pool
area and the new pool house. Detailed drawings of the buildings are included with this
application.
A green house (392 sf) is proposed to the east of the existing residence and approximately
44-120 feet from the adjacent properties and is just under 17 feet in height. The first ten
feet of height will be stone like the other buildings, with the remaining portion being a
skylight.
The entrance into the property on Deforest Road is also proposed to be modified. The
existing retaining wall will be reconstructed, and a new entrance feature and gate is
proposed. The existing gate is a sliding gate, while the proposed gate swings open into the
property. The Fire Department will require that the entry gate be equipped with GTT
Opticom sensor for emergency apparatus to open the gate and a Knox override in the event
of malfunction. There are no planned improvements to the existing asphalt driveway from
the entry gate to the house. While most residences can be accessed by the fire department
and fire apparatus from the street or fire lane that is constructed, typically of concrete, to
withstand the weight of the fire apparatus (80,000 lbs.), this driveway is approximately a
quarter of a mile in length and is constructed of asphalt. Staff is concerned that the
driveway may be damaged if they have to respond to a call at this address. A PD condition
that the city will not be responsible for repairing the driveway for any damaged that may
be caused responding to a call at this address from emergency apparatus.
