RE: Oakwind Estates Phase 1—Noise Abatement Alternative Compliance
Dear Planning Staff,
The Oaks Build to Rent LLC is applying for final plat approval of Oakwind Estates Subdivision Phase 1.
As part of the Phase 1 Construction Plans, per the City of Meridian Staff Report, noise abatement is
required for the subdivision frontage along McDermott Rd.
The proposed construction for the noise abatement is a 4 ft tall berm in combination with 6 ft tall fence.
The fence is Simtek® Ashland® style product by CertainTeed. It is composed of steel reinforced
polyethylene fence panels and posts. It has an STC 26 rating according to ASTM E 90 Sound
Transmission Loss Test.
The fence has been approved as a noise abatement alternative by the City of Meridian through
coordination and submittal by Toll Brothers.
Phase 1 of the subdivision has approximately 1,230 linear feet of frontage along McDermott Road and
proposes 1,166 linear feet of noise abatement fence. Less fence than frontage is proposed due to
subdivision pathway connections to McDermott Rd and existing easements.
Alternative Compliance is required by the City of Meridian UDC as the proposed installation does not
conform with UDC section 11-3H-4.D.1.c.2. Section 11-3H-4.D.1.c.2 states "the wall shall be staggered
every three hundred (300) linear feet subject to subsection (D)(3)B of this section that prohibits breaks in
the wall."
Construction of the Simtek®Ashland@)noise abatement fence is not intended for staggering as described
in the UDC. It is proposed the construction of the noise abatement fence is linear without staggering.
This construction will be similar to the vinyl fencing proposed for the rest of the subdivision and the existing
adjacent road frontages for Oaks North and Oaks South developments.
The "Red Cedar" color option has been chosen for this subdivision. Below are pictures of the proposed
noise abatement fence.

This request meets the requirements of UDC 11-5B-5.B.2 regarding the conditions when alternative
compliance are allowed; specifically condition "(f) Additional environmental quality improvements would
result from the alternative compliance."
The additional environmental quality improvements by granting this alternative compliance request are:
• Aesthetically pleasing nature of the fence and how the fence will blend with proposed
landscaping and adjacent the existing adjacent subdivision developments.
The proposed fence meets the noise abating needs of the subdivision and is more aesthetically pleasing
than a traditional concrete or modular block noise abatement wall, even one that is staggered per City of
Meridian Code. Additionally, the red cedar color and slatted appearance style will blend better with the
proposed landscaping within the McDermott Rd landscaped buffer.
