least 7 feet above ground. Two 2 x4" diagonal braces should be nailed to the inside bock of the
posts and staked at the ground to provide stability against wind or soft soil conditions if posts
are less than 24 inches into the ground,
The notice board shall be attached to the posts with four lag bolts and washers (3/8 inch dia.
and 3" long)
No tice BOGrd L OCG t10n.'
The notice board shall be located°
• At the midpoint on the site street frontage or as otherwise directed by DOES staff
maximize 11sibillty
At a location 5 feet inside the street property line, a notice board structurally
attached to on existing building shall be exempt from the setback provisions,
provided that the notice board is located not more than 5 feet from the property
line without approval from DOES staff
• So that the top of the notice board Is between 7 to 9 feet above grade.
• So that it is totally visible to pedestrians

7. The geotextile used must meet the standards listed below. A copy of the
manufacturers fabric specifications must be available on —site.
AOS (ASTM D-4751) = 30-100 sieve size (0.60-0.15 mm) for slit film
50-100 sieve size (0.30— 0.15 mm) for other fabrics
Water Permittivity (ASTM D-4497) — 0.02 SEC min.
Grab Tensile Strength (ASTM D-4632) = 180 lbs min. for extra strength fabric
100 Ibs min. for standard strength fabric
Grab Tensile Elongation (ASTM D-4632) a 307. max.
Ultraviolet Resistance (ASTM D-4355) = 707 min.
2. Standard strength fabric requires wire backing to increase the strength of the fence.
Wire backing or closer post spacing may be required for extra strength fabric if
field performance warrants a stronger fence.
J. Where the fence is installed, the slope shall be no steeper than 2N° 7V,

Maintenance Standards
1. Any accumulated sediment on or around the �Iter fabric protection shall
be removed immediately, Sediment shall not be removed with water, and
all sediment must be disposed of as 611 on —site or hauled off —site.
2. Any sediment in the catch basin insert shall be removed when the sediment
has filled one—third of the available storage. The filter media for the insert
shall be cleaned or replaced at least monthly,
3 Regular maintenance is critical for both forms of catch basin protection.
Unlike many forms of protection that fail gradually, catch basin protection
will fail suddenly and completely if not maintained properly,
