Plan submitted as part of the Storm water Report dated May 2013 must be revised to the

additional guidance on required revisions to the maintenance schedule. The final

the owner's expense. Section 281-8 of the Northampton Stormwater Management
Ordinance provides additional guidance for the requirements of this agreement.

and timing of sediment and erosion control measures that may be required during
construction of the roadway and swales including but not limited to stone check dams,
temporary sediment basins, silt fence, and other measures to slow down the velocity of
construction flows and settle out sediment prior to discharge to the roadway ditch or
culverts.

flows. If, after construction of the proposed system, the system is found to increase
stormwater flows or pollutants in these flows to adjacent properties or to the municipal
roadway and storm drain system, the owner shall redesign and reconstruct the drainage
system to prevent any increased stormwater flows to adjacent properties or the municipal
storm drain system.
4. All detention basins, outlets, vegetated swales, level-lip spreaders and other non-piped
components of the proposed storm water system shall be constructed as proposed and
st<lbilized as soon as possible during construction of the driveway and preferably prior to
receiving drainage flows from the proposed development. Additional erosion and
sediment control structures may be required during construction.
5. Tile Site Plans specify the Limit of Work and the area of proposed impervious surface
c:111cl gravel driveway. Any expansion of the cleared area beyond that specified on the plan
