System Performance Evaluation For Ditches & Canals:

Service Level A: Flow is contained within the system (i.e., no flooding of major roadways, minor roadways, yards or buildings occurs)

Service Level B: Flow is contained within the right of way (i.e., flooding is limited to the outer lane of major roadways and right-of-way area of yards)

Service Level C: Flooding of minor streets precludes travel and flooding of yards is at the buildings but no structure flooding occurs.

Service Level D: Extensive flooding of yards including buildings.

Note: Level of Service Objective = “B” Level “C” is considered deficient

Level “D” is considered unacceptable

Level of Service Evaluations

Section 35 and 37 High water levels due to

Constrictions at London Drive, US 1 (to Hulett Branch) I-95 (to Mulberry Creek)

Home flooding predicted in < 1 % of homes (all in Bird of Paradise area) Number of homes below City standard for 100-year event = 9% - 11 % Secondary drainage deficiencies - 10 year event = 2 % - 6%

Modeling Results

Sections 35 & 37 – Recommended Capital Improvements

Possible Detention Storage Locations ~100-acft required in total

Storage Capacity Breakdown

COPC needs a total of 100acft of storage capacity within Sections 35 and 37.

COPC currently owns enough property to create 70.85acft of storage capacity.

With the additional area acquired from the Drummond property the City would have a total of 78.53acft.

The Drummonds property acquisition also includes existing drainage ditches that serve the community wide drainage system.

Next Steps

Accept Donation of 70 Laramie DriveEnter into a land transaction to acquire

additional storage capacity and drainage ditches on the Drummonds property.

Partial compensation for Drummonds property will be the transfer of 70 Laramie Drive to the Drummonds.
