Each unfit shall be constricted at the locations and elevations according to the sizes shown om the approved drawings. Any modifications to the elevation or location shall be at the direction of and approved by the Engineer. B. If the Fillterrao is stored before installation, the top slab must be placed on the box using the; 2x4 wood provided, to prevent any contarnination from the site. All internal fittings stupplied (if any), must be left in place as per the delivery. C. The unit :shall be placed on a compacted sub -grade with a minimum 6 -inch gravel base matching, the final grade of the curb line in the area of the unit. The unit to be placed such thatt the unit and top slab match the grade of the curb in the area of the unit. Compactt undisturbed sub -grade materials to 95% of maximum density at +1- 2% of optimum) moisture. Unsuitable material below sub -grade shall be replaced to the site engineer'!s approval. T). nutlet connections shall be aligned and sealed to meet the approved drawings with modificattions necessary to meet site conditions and local regulations. E. Once the unit is set, the internal wooden forms and protective mesh cover must be left intact. Reemove only the temporary wooden shipping blocks between the box and top slab. The; top lid should be sealed onto the box section before backfilling, using a non- shrink grrout, butyl rubber or similar waterproof seal. The boards on top of the lid and boards seaaled in the units throat must NOT be removed. The Supplier (Americast or its authonized dealer) will remove these sections at the time of activation. Backfrlling should bce performed in a careful manner, bringing the appropriate: fill material up in 6" lifts on all sides. Precast sections shall be set in a manner that will result in a watertiglnt joint. In all instances, installation of Filterra® unit shall conform to ASTM specificattion C891 "Standard Practice for Installation of Underground Precast Utility Structures ", unless directed otherwise in contract documents. F. Curb and gutter construction (where present) shall ensure that the flow -line of the Filterra® units is at a greater elevation than the flow -line of the bypass structure or relief (dr(op inlet, curb cut or similar). Failure to comply with this guideline may cause failure amdl,'or damage to the Filterra® environmental device. G. Each Filtterra® unit must receive adequate irrigation to ensure survival of the living system duuring periods of drier weather. This may be achieved through gutter flow or through t}he tree grate. 06%28105 FILTERRA 9YPASS FLOW DIRECTED T01 A LOWER POINT OF RELIEF www.filterra.com GRASS SWALE CONCRETE SWALE AND TRANSITION AT FILTERRA Toll Free: (866) 349-3458 r--------- - - - - --i FILTERRA I i I / ,' DRAWING AVAILABLE IN TIF FILE FORMAT.

This process cannot commence until the project site is fully stabilized and cleaned (full landscaping, grass cover, final paving and street sweeping completed), negating the chance of construction materials contaminating the Filterram system. Care shall be taken during construction not to damage the protective throat and top plates. B. Activation includes installation of plant(s) and mulch layers as necessary Maintenance A. Each correctly installed FilterraV unit is to be maintained by the Supplier, or a Supplier approved contractor for a minimum period of 1 year. The cost of this service is to be included in the price of each Pilterra(V unit. Extended maintenance contracts are available at extra cost upon request. B. Annual maintenance consists of a maximum of (2) scheduled visits. The visits are scheduled seasonally: the spring visit aims to clean up after winter loads including salts and sands. The fall visit helps the system by removing excessive leaf litter. C. Each maintenance visit consists of the following tasks. 1. Filterram unit inspection 2. Foreign debris, silt, mulch & trash removal 3. Filter media evaluation and recharge as necessary 4. Plant health evaluation and pruning or replacement as necessary 5. Replacement of mulch 6.
