Cambridge Properties Personnel:
Our office has received multiple complaints related to water running into the road nearby the stormwater pond at
the referenced site. Upon reviewing our files and database, I found inspection reports from 2021 and 2022
indicating non-compliance issues related to the post construction stormwater permit. AJuly 2022 letterfrom our
office to Cambridge Denver LLC,Attention George Maloomian indicated that repairs to the level spreader were
needed, requested an investigation into the seepage hole below the retaining wall west corner, and requested that
a plan for repair and maintenance of the basin as well as the BMP inspection and maintenance records be sent to
the Mooresville Regional Office by August 30, 2022.
Upon reviewing our file,these additional requested records could not be located. Email records after August 20,
2022,appear to indicate that some repairs were being made at the site. The current status of these issues is
currently unclear to our office.
Someone from our office will be in touch with you within the next month to conduct a Stormwater Inspection at
this site. The purpose of this email is to request that someone from your group meet us on site and bring copies of
all the BMP operation and maintenance records, as well as copies of any records or Engineering Reports related to
the drainage issue.
Additionally, upon viewing aerial photographs of the site, it appears the stormwater pond has a dam that is
immediately upgradient of a busy road. Please see the attached Jurisdictional Determination/Hazard
Classification Request form. Please complete the referenced form and submit as described on the form so that
the jurisdictional status of the referenced dam may be determined. With a proximity so close to a major road, it is
likely that this dam could be classified as a high-hazard dam. If this form has been previously submitted, please
provide a copy.
Please let me know if you have any questions.

Inspection Summary:
Based upon the inspection conducted, maintenance is needed at wet pond one. Wet pond one is showing signs
of erosion from water flowing from the far end of the level spreader. A scour an inch or two deep is located at
the end of the level spreader. Additonally, at the west corner of wet pond one, a small hole has formed at the
base of the retaining wall. These two issues are sending sediment to the southern entrance/exit of the Cameron
Village Shopping Center on NC-16.

Inspection Summary:
During the inspection of the basin, multiple items requiring repair were noted. A small hole measuring
approximately 3 inches in diameter is located at the west corner at the base of the retaining wall. While there
was no flow at the time of the inspection, complainants have alleged that seepage is occurring at this hole
during rain events. This seepage must be investigated and the hole repaired. The rock along the level spreader
is sparse.Additionally, erosion is occuring at the west end of the level spreader.Additional rock is needed along
the level spreader and the erosion must be repaired and stabilized. The skimmer is still installed on the riser
structure. This should be removed.
Additionally, no records of BMP inspection and maintenance were located. Please provide these to the
Mooresville Regional Office for the dates August 23, 2021 to June 30, 2022.
Please send BMP records as well as a plan for repair and maintenance of the noted compliance issues by

Inspection Summary:
A seepage hole approximately 3 -4 inches deep was present at the west corner of the retaining wall. Wetness
on Baxley lane was identified during the inspection as being caused by the seepage hole due to dry toe drains
and the distance from inactive sprinkler systems. The wetness on Baxley Lane was accompanied by algae and
a small amount of sediment indicating extended periods of wetness in the street.
Erosion was present at the end of the level spreader and consisted of a single scour measuring 2-3 feet in
length and about 6 inches deep. A portion of the gravel pad for the level spreader has washed away.
The skimmer should be removed from the basin's riser as it is no longer needed.
