2. All clearing, grading, drainage, construction, and development of the 263 King Street -
Lia Honda Vehicle Storage shall be conducted in strict accordance with the plans,
information, and conditions specified in the Stormwater Management Permit Approval
dated 4/27 /06, revised plans and calculations dated 10/17 /2006 and as amended by the
above referenced plans and information and as amended by conditions attached to this
permit amendment.
Specific Permit Conditions:
1. The Northampton Department of Public Works (DPW) understands that the applicant and
owner are proposing to proceed with construction work that would be covered under an
Amendment to the Stormwater Management Permit issued for 263 King Street-Lia
Honda Vehicle Storage on April 27, 2006 and that the previously issued Amendment to
the Stormwater Management Permit issued for 263 King Street-Lia Kia on September
10, 2009 is no longer applicable. The DPW hereby revokes the Amendment to the
Stormwater Management Permit issued on September 10, 2009.
2. Previously, the DPW had required that the applicant confirm with As-Built Plans and
revised drainage calculations that the Lia Honda Vehicle Storage project had been
completed in accordance with the approved plans and specifications. Lia Honda
Additional Parking As-Built Plans dated August 13, 2009 as well as revised Drainage
Calculations dated October 2, 2009 were submitted to the DPW by Mark A. McClusky,
P.E., Huntley Associates, P.C. The DPW reviewed the As-Built Plans and Drainage
Calculations and discovered that the stormwater management system and the parking lot
islands at 263 King Street had not been constructed in accordance with the approved
plans and specifications and the stormwater management system was not functioning
according to the approved design. Particularly the post-construction peak runoff rates
from the site were not in compliance with the requirements of the Northampton
Stormwater Ordinance or the approved Stormwater Management Permit. The proposed
Lia Kia Site Plans and Drainage Report from June 21, 2012 indicate that post-
development peak runoff rates will be less than pre-development runoff rates for all
design storms and all design points. However, there is additional information and
revisions that are required to confirm that the proposed stormwater system will function
according to design. The DPW requests that within 30 days of the issuance of this
Amendment, the following information must be submitted to the DPW for approval in the
form of revised plans and documentation:
a. The design of the subsurface detention/infiltration system has been proposed with
an outlet through an existing catch basin to the drain line. The subsurface
detention basin must have a direct piped connection to a drain line preferably at a
manhole. The plans must be revised to show this connection.
b. The plans must be revised to specify the elevations and details of the outlet
structure of the subsurface detention/infiltration system consistent with the
specifications in the drainage calculations.
c. A soils investigation (by a Certified Soil Evaluator or Certified Professional Soil
Scientist) must be conducted and documentation submitted to the DPW for
approval including test pits or other tests at the location of the proposed
subsurface detention/infiltration system. Information must be submitted to the
DPW verifying the soil conditions, the elevation of estimated seasonal high
groundwater, and how the proposed rate of infiltration was calculated. Since

Storage\0263 King St -Lia Honda_ Amendment 2.doc

infiltration is proposed, the soil test must demonstrate a separation of at least two
feet between the bottom of the structure and the elevation of estimated seasonal
high groundwater. If the soils investigation reveals groundwater or soil conditions
inconsistent with the proposed design of the subsurface detention/infiltration
system, the applicant must submit an alternative design to the DPW for approval.
d. Sheet 6 of the Site Plans shows three enlarged parking lot islands and refers to
Note 1. Landscape (Grass or Ground Cover). This note must be revised to specify
only grass to be consistent with the drainage calculations.
e. Sheet 7 of the Site Plans includes a note: "Remove Detention Basin. Grade to
Sheet Flow," in the southeast corner of the site. Additional spot grades are
necessary to clarify how the area will be graded.
3. The proposed stormwater management system and site work is designed to mitigate peak
stormwater flows. If, after construction of the proposed project, the site is found to
increase or concentrate stormwater flows to adjacent properties or roadways, the owner
shall redesign and reconstruct the drainage system to prevent any increased stormwater
flows to adjacent properties.
4. Construction plans shall be submitted to the DPW for approval prior to the start of
construction. The construction plans will be reviewed by the DPW for additional
information and consistency with the approved plans and specifications.
5. A Stormwater Management Operation, Maintenance and Inspection Agreement was
recorded on November 21, 2006 for the Lia Honda site. This Agreement must be
amended or a new Agreement recorded that includes maintenance and inspection items
for all new components of the proposed stormwater management system. Lia Kia and Lia
Honda must continue comply with all future operation, maintenance, inspection, and
reporting requirements of the approved stormwater management systems or face notice(s)
of violation and fines for non-compliance. In accordance with the Stormwater
Management Permit, annual reports that are stamped by a Registered Professional
Engineer documenting the actions completed as required by the Operation, Maintenance,
and Inspection Agreement shall be submitted to the Northampton Department of Public
Works by October 1st of each year.
