About this file
This is a Grading, Erosion & Sediment Control (GESC) Plan prepared by RESPEC Company LLC for the Cherry Creek Basin Water Quality Authority (CCBWQA) and Colorado Parks and Wildlife (CPW) for the East Shade Shelters Shoreline Stabilization Project located at Cherry Creek Reservoir in Arapahoe County, Colorado. The project involves shoreline stabilization work spanning approximately 561 linear feet, with multiple phases including initial, interim, and final erosion control measures. The plan details specific erosion control techniques such as construction fencing, silt fencing, sediment control logs, stabilized staging areas, and slope protection methods. The project is scheduled for implementation in July 2024, with comprehensive documentation submitted to Arapahoe County under case number EE24-030.
The GESC plan focuses on controlling potential pollutants during construction and ensuring final site stabilization through various engineering and environmental control measures. The project area includes a group picnic access area, concrete staircase, and shade shelter, with careful attention to maintaining slopes at 3:1 or less and implementing seeding and mulching of disturbed areas within 14 days if sites will remain undisturbed for over 30 days. The United States of America is listed as the property owner, with the project area located at 6060 Broadway, Denver, CO 80216. The plan emphasizes ongoing erosion control, sediment management, and water quality enhancement throughout the construction process, with specific requirements for installing and maintaining control measures to prevent environmental degradation.

THIS GRADING, EROSION AND SEDIMENT CONTROL (GESC) DOCUMENT HAS
BEEN PLACED IN THE ARAPAHOE COUNTY FILE FOR THIS PROJECT AND
APPEARS TO FULFILL THE LATEST VERSION OF THE ARAPAHOE COUNTY
GRADING, EROSION AND SEDIMENT CONTROL MANUAL. ADDITIONAL
GRADING, EROSION AND SEDIMENT CONTROL MEASURES MAY BE
REQUIRED OF THE OWNER AND HIS/HER AGENTS, DUE TO UNFORESEEN

FUNCTION AS INTENDED. THE REQUIREMENTS OF THIS GESC PLAN SHALL
RUN WITH THE LAND AND BE THE OBLIGATION OF THE LAND OWNER, OR
HIS/HER DESIGNATED REPRESENTATIVE(S) UNTIL SUCH TIME AS THE PLAN
IS PROPERTY COMPLETED, MODIFIED OR VOIDED.
ARAPAHOE COUNTY CASE NUMBER: EE24-030
I HEREBY ATTEST THAT THIS GRADING, EROSION AND SEDIMENT CONTROL
(GESC) DOCUMENT FOR THE EAST SHADE SHELTERS SHORELINE
STABILIZATION HAS BEEN PREPARED BY ME OR UNDER MY DIRECT
SUPERVISION, AND TO THE BEST OF MY KNOWLEDGE AND ABILITY HAS BEEN
PREPARED IN ACCORDANCE WITH THE LATEST VERSION OF THE ARAPAHOE
COUNTY GESC MANUAL. THE SIGNATURE AND STAMP AFFIXED HEREON
CERTIFIES THAT THIS GESC DOCUMENT WAS PREPARED IN ACCORDANCE
WITH THE REQUIRED REGULATIONS AND CRITERIA; HOWEVER, THE STAMP

NOTES
1. APPROPRIATE CONTROL MEASURES MUST BE
IMPLEMENTED PRIOR TO THE START OF LAND
DISTURBANCE ACTIVITY, MUST CONTROL
POTENTIAL POLLUTANTS DURING EACH PHASE
OF CONSTRUCTION, & MUST BE CONTINUED
THROUGH FINAL STABILIZATION. APPROPRIATE
STRUCTURAL & NON-STRUCTURAL CONTROL
MEASURES MUST BE MAINTAINED IN
OPERATIONAL CONDITION.
2. SEE STANDARD NOTES & DETAILS (EC-7) FOR
LEGEND OF CONTROL MEASURES NAMES &
SYMBOLS.
3. STAGING AREA SHALL BE PLACED ON EXISTING
ASPHALT AND NOT REQUIRE STABILIZATION.
ASPHALT SHALL BE PROTECTED FROM
DAMAGE.
INITIAL
4. ANY CONTROL MEASURES SHOWN THAT
REQUIRE GRADING, (E.G. SEDIMENT BASINS,
SEDIMENT TRAPS, CONCRETE WASHOUT
AREAS, ETC.), SHALL NOT BE PLACED UNTIL
AFTER THE PRE-CONSTRUCTION MEETING IN
ISSUANCE OF THE GESC PERMIT, BUT MUST BE
FULLY FUNCTIONAL PRIOR TO ANY
LARGE-SCALE GRADING. THE INITIAL PLAN
ILLUSTRATES EXISTING CONDITONS. NO
PROPOSED INFRASTRUCTURE IS SHOWN.
INTERIM
5. CONTROL MEASURES WERE INSTALLED IN THE
INITIAL STAGE & SHALL BE LEFT IN PLACE IN
THE INTERIM STAGE UNLESS OTHERWISE
NOTED.
6. CONTROL MEASURES, INCLUDING SEEDING
AND MULCHING OF DISTURBED AREAS, MUST
BE COMPLETED WITHIN 14 DAYS, IF THE AREA
WILL REMAIN UNDISTURBED FOR A PERIOD
GREATER THAN 30 DAYS.
