PLN20170065, Ballinger View 3 lot short plat
23521 75th Ave W
The comments provided below are based upon review of the preliminary civil plans & documents for the subject short plat. Additional information is requested from the applicant at this
time in order to continue review of the application and provide preliminary approval of the short plat. Please ask the applicant to provide a written response to each of the comments
below and revise and resubmit plans accordingly.
1st Review – 1/31/18
2nd Review – 6/25/18
GENERAL
6/25/18 – Comment was addressed; however, it has been determined that curb/gutter and sidewalks are not required. Please show the following items are being met.
Show the street being widened; such that there is an 11’ lane width.
Show a thickened edge so that surface water runoff from the road does not enter the site.
1/13/18 Comment: Show the collection of the street surface water runoff from the flow line of the new curb/gutter being collected and directed to the the City storm system.
The curb line will need to move to the east to allow for an 11’ lane width.
Based on the rim elevation provided and the topographic lines, it appears that the flow line could go both north and south. Please provide spot elevations so that it is clear which
direction the surface water will go.
OK
6/25/18 – Comment was addressed; however, since there is no longer a requirement for sidewalk, the tree should remain. Please show as such on the plans.
1/13/18 Comment: Please show the tree located partially within the right-of-way as to be removed.
OK
6/25/18 – Comment was addressed; however, the proposed driveway layouts are not consistent with City policy. During the subdivision of properties the City attempts to limit the number
of driveways that have access to City streets. Since your plan shows that it is feasible to have each of the three lots take access off of a private drive, please show as such on the
plans.
1/13/18 Comment: Based on the proposed driveway layout the City will not approve two driveways to be constructed off of 75th Ave W. Please show all three homes accessing off of the
private access road.
UTILITIES
OK
6/25/18 – Comment was partially addressed. The City sewer main has not been shown accurately on the plans. This review comment can be addressed during the Civil review phase if you
choose.
1/13/18 Comment: Show all City utilities within 75th Ave W (Sewer has not been shown in its entirety and water has not been shown).
OK
6/25/18 – Comment was partially addressed. The plans do not show the back of water meter at the property line and the plans show private water service lines running within the City
right-of-way. The meter will need to be relocated to the property line and all portions of the water service (form the meter to the house) will need to be located on private property.
This review comment can be addressed during the Civil review phase if you choose.
1/13/18 Comment: Show the water service lines (existing and proposed) from the main to the meter and from the meter to individual property line.
6/25/18 – Comment was addressed; however, it appears based on the inverts provided that portions of the sewer is less than 2%. Please revise the plans accordingly.
1/13/18 Comment: Show the sewers lines (existing and proposed) to each individual lot.
Provide approximate invert elevations for side sewer at existing home (if relocating), property lines and new connection to main to show feasibility.
The sewer must be a minimum have 10’ horizontal separation from the water.
OK
6/25/18 – Comment was addressed; however, it appears that there is a need for a utility easements for the water services (See comment 4) and dry utilities (the City requires the dry
utilities to enter the property immediately and not run parallel lines within the City right-of-way). Typically there is a 10’ public easement along the property line adjacent to
City right-of-ways to accommodate for utilities.
1/13/18 Comment: Show all utility easements.
STORM
There are no further comments for storm for the preliminary short plat phase; however, see attached document from the City’s Stormwater Engineer, Zack Richardson, PE. For items to be
addressed during the Civil review phase.
Thank you.
