to obtain a determination of cash-in-lieu (CIL) of water rights.
Response: Included in this application is correspondence with Brian Heaston
with the City of Engineering Department stating that CIL of water rights
were provided when the Ph 3 Cattail Creek plat was filed. A credit of 4.85
AF exists for the subject properties. This credit supports 39 MF living units
at the MF unit demand of 0.124 AF,well above the 16 proposed for Collins
Apts. Therefore, payment of CIL of water rights is not required for this
project.
4. BMC 38.410.070.A.1: Municipal water, sanitary sewer, and storm system
a. Water and sewer service may not be located within 1 Oft of a structure. The
proposed services are proposed to be routed beneath the front awnings and
entrance divider wall.
Response: The private water and sewer services are a minimum of 5' from
the structures because the site constraints do not allow us to meet a minimum
of 10'. Finally,we are unable to locate this 10' separation requirement in the
COB DSSP, MDEQ Circulars, or ARMS.
b. Water and sewer service must be located a minimum of 5 ft from a property. The
service cannot be reasonable maintained.
Response: Water and sewer services are proposed to be located a minimum
of 5 ft from the property line.

service line must be shown on the site plan and the alignment reviewed prior to
site plan approval. In addition the applicant must prepare plans and specifications
for any fire service line in accordance with the City's Fire Service Line Policy.
The plans must be prepared by a Professional Engineer and be provided to and
approved by the City Engineer prior to initiation of construction of the fire service
or fire protection system. The applicant must also provide Professional
Engineering services for construction inspection, post-construction certification
and preparation of mylar record drawings. Fire service plans, and domestic
services 4" or larger, must be a standalone submittal, separate from the site plan

6. BMC 38.540.020.M: Snow removal storage area—
a. Must demonstrate reasonable storage and conformance to drainage design. Snow
may not be plowed to the end of the drive aisle as there is insufficient area and
drainage will be directed to the adjacent property.
Response: Additional area has been included at the end of the drive lanes to
increase snow storage area. A runoff inlet is proposed at the north end of the
parking lot to capture drainage runoff as well as inlets in the center of the
site.
