The following narrative is respectfully submitted as a description of the proposed
Canterbury Commons subdivision. This project complies with the Findings of Fact and
Conditions of Approval approved on October 3, 2006 for case numbers: AZ-OS-013, PP-06-011,
CUP-06-006, and PS-06-005. The project covers 13.99 acres located on the south side of West
Pine Avenue between North Gray Cloud Way and North Ocean Avenue. The project covers
parcels 51211325710, S1211325610, 51211325499, 51211325420, 51211315300, and
S 1311314810. Currently, there are three single-family homes and associated outbuildings on
this site. All existing building will be removed as part of this development. The site is located in
the City of Meridian, Ada County and is zoned R-15. '~
The technical and planning aspects of this proposed development are described in greater
detail below.
AZ-OS-013 COMPLIANCE
The City of Meridian Future Lari~l Use Map adopted on August 6, 2002 was used to
verify the proposed residential designation as being in compliance with the Meridian
Comprehensive Plan. This map indicates that the future land use for this property is Medium
Density Residential. Per the Comp Plan Amendment, Resolution No. 04-454, Medium High
Density Residential is defined as follows:
Medium High Density Residential: areas are locations recommended primarily for
relatively dense multi-family housing types, such as row houses, townhouses,
condominiums and apartment buildings and complexes. Medium High Density
Residential areas should include a mix of housing types that achieve an overall average
density target of 12 dwelling units per gross acre.
• The development is in conformance will the R-15 zoning standards with regards to
property size, setbacks, density, and fences.
PP-06-011 COMPLIANCE
The final design of the project was done in conformance with the approved preliminary
plat and meets all requirements or conditions thereof. Minor changes have been made on the
final plat. These changes include street renaming and removing one condominium building.
Building #39 on the preliminary plat will be replaced with a 3-unit townhouse. The public street
previously known as N Sherwood Avenue will be known as N ~Amuma Avenue. The private
street previously known as North Lyndhurst Lane will now be known as N Clara Lane.

space, parking, amenities, elevations, internal pedestrian paths, Eight Mile Lateral and Ten Mile
Drain, existing residences and buildings, multi-family setbacks, refuse areas, Pine Avenue street
buffer, open space, fencing, pressure irrigation, private streets, and site layout/density. There are
a total of 192 residential condominiums and a net lot density of 18.9. These 192 units are
divided into 48 buildings, 4 units per building. The smallest unit is 937 square feet; the average
unit is 1,109 square feet. The total area of open space is approximately 2.44 acres. This open
space is 55.18% of the project area. 100% of the open space is usable as defined in Title 11,
Chapter 3, Article G of the Unified Development Code.
PS-06-005 COMPLIANCE
This site has been designed to comply all requirements for the private streets. All private
streets have been designed to allow a minimum 24 foot wide drive surface. Access to this
subdivision is limited to the two access points on West Pine Avenue. Direct lot access to West
Pine Avenue is prohibited. ^
ENGINEERING /UTILITY /DRAINAGE
Public utilities in West Pine Avenue will provide connections for both sanitary sewer and
domestic water service to the Canterbury Commons Subdivision. Sanitary sewer service shall be
obtained by connecting a gravity line to an existing manhole. This sewer main gravity flows to a
pump station at the intersection of Ten Mile Road and West Pine Avenue. A twelve inch
domestic water main located West Pine Avenue shall be utilized for botli'fire hydrant service and
domestic water service. These facilities shall be public facilities within the proposed
subdivision.
Pressurized irrigation shall connect to an existing Nampa Meritdian Irrigation District
pressurized pipe located in the Lyndhurst Grove and Kelsee Park subdivisions. This facility will
provide landscape irrigation for the individual lots, open space, and the proposed landscape
buffers adjacent to West Pine Avenue.
Storm runoff from these lots will be retained on site or discharged at historic rate to the
Ten Mile stub drain. Runoff `from N Clara Lane and W. Synder Lane will be captured in sand
and grease traps and then discharged into the Ten Mile stub drain. Runoff from N Amuma
Avenue will be captured in catch basins and discharged to the proposed retention pond. All
other runoff will be captured and discharged through subsurface seepage beds. Runoff from
each lot will be retained in subsurface infiltration beds
..
All street finish centerline elevations are set above the minimum of three feet above the
highest established normal groundwater elevation. _

,k The project site is partially developed land located south of W. Pine Avenue, west of N.
Ocean Avenue, and east of N. Gray Cloud Way in Meridian, Ada County, Idaho. This report
represents engineering suplibrt calculations for site development plans for Canterbury Commons.
The project site consists of approximately 20.5 acres of total land. The adjacent land to the east is
Morning Glory Subdivision, to the north are Haven Cove Subdivision No. 09, Kelsee Park,
Lyndhurst Grove, and the future Sommersby No. 02, and to the west is Courtyards at Ten Mile
and Central Valley Baptist Church. A portion of the Eight Mile Lateral passes through the
property in the northeast corner. The Ten Mile stub drain runs parallel to the property on the west
side. The project site slopes from northeast to southwest at an average of 2%. All storm water
sheet flows to the Ten Mile stub drain.
The project site covers parcel numbers S 1211325710, S 1211325610, S 1211325499,
S 1211325420, S 1211315300, and S 1211314810. There are three residences and other accessory
buildings on the site. r
Test pits generally encountered 1 to 3 feet of lean clay at the existing ground surface with
silty sands and poorly graded sands below with infiltration rates varying between 2 and 8 inches
per hour. Based on groundwater monitoring performed on a monthly basis through December
2005 and October 2006, groundwateris expected between 6 to 10 feet below existing grade.
MODIFIED CONDITIONS
The modified conditions for the project site include the street construction to serve the
future residences. Multifamily condominiums and single family attached townhomes will be
'~' constructed in 2 phases. All condominiums, utilities, perimeter fencing, and supporting roads will
be constructed in the first phase. The remaining utilities, roadways, and townhomes will be
constructed in the second phase. Storm runoff from these lots will be retained on site or
discharged ~'t historic rate to the ten mile stub drain. The proposed street improvements include
asphalt pavement, curb and gutter, and sidewalks. Runoff from N. Lyndhurst Lane and W. Synder
Lane will be captured in sand and grease traps and then discharged into the Ten Mile stub drain.
Runoff from N. Sherwood Avenue will be captured in catch basins and discharged to the proposed
retention pond. The retention pond is designed to accommodate the required volume of runoff
from the 100-year storm event. Infiltration rates are considered as part of the volume sizing
calculations. The one hour storm is used to calculate the required volume for storm runoff. All
-other runoff will be captured and discharged through subsurface seepage beds. All calculations
have been included in the attached appendix. Runoff from each lot will be retained in subsurface
infiltration beds. Lot grading and drainage is not included as part of this study.
The City of Meridian Standard Specifications, City of Boise Storm Water Management
Design Manual, and Ada County Highway District Design Policy Manual were referenced to
determine the appropriate seepage bed sizing for the proposed condition drainage basins. The
Rational Method was used for volume calculations and for peak flow calculations. A 100 year -
one hour event was used for volume calculations. This event yields 1.1 inches of rainfall during
that hour. A geotechnical xeport has been prepared by Strata, Geotechnical Engineering and
Materials Testing, dared Apri126, 2007. A copy has been provided with this submittal.
Drainage Zone 1 has an area of 20,194 square feet, a C factor of 0.73, and yields 0.37
cubic feet in runoff in the design storm. Runoff from Zone 1 flows to one of two catch basins on
the north and south sides of the eastern portion of W. Jayton Drive (public). After passing through
the catch basin on the north side of W. Jayton Drive, runoff will be delivered to the catch basin on
