About this file

Written by GovTribe AI · Jul 31, 2025

This document is a comprehensive set of engineering and design plans for the Perry Park Green Infrastructure Improvements project, prepared by Geosyntec Consultants and MKSK Studios for the Joseph Jones Drain Drainage District in Pontiac, Michigan. The project involves creating a stormwater management system with green infrastructure improvements, including a stormwater wetland, drainage infrastructure, pedestrian paths, landscaping, and site restoration. The plans are dated May 9, 2025, with a subsequent re-bid date of July 29, 2025, and cover 19 detailed sheets including site layouts, grading, utility plans, erosion control, landscape design, and construction details.

The project is funded by the Clean Water State Revolving Fund (CWSRF), with federal award number SLRFRP0127 from the U.S. Department of the Treasury to the State of Michigan. The total project area is approximately 9.4 acres, with a composite runoff coefficient of 0.36. The design includes stormwater management calculations for channel protection, volume control, and 100-year detention, with a designed pump station and wetland system to reduce non-point source pollution. The project aims to improve water quality by collecting stormwater runoff, facilitating infiltration, and providing vegetative treatment. The site will feature native landscaping, including trees, shrubs, and ground cover, with specific attention to soil preparation, planting techniques, and long-term maintenance considerations.

DISCHARGES FROM DEWATERING ACTIVITIES, INCLUDING DISCHARGES FROM DEWATERING OF TRENCHES AND EXCAVATIONS, ARE PROHIBITED UNLESS MANAGED BY APPROPRIATE CONTROLS. IN NO CASE IS WATER FROM

DEWATERING ACTIVITIES TO BE PUMPED OFF-SITE WITHOUT BEING PROPERLY TREATED.

DEWATERING THAT HAS SEDIMENT-LADEN WATER MUST DISCHARGE TO A SEDIMENT BASIN OR EQUIVALENT SETTLING, FILTERING, OR ENERGY DISSIPATION MEASURES TO REMOVE SUSPENDED SOLIDS BEFORE DISCHARGE.

SEDIMENT BAGS, INFILTRATION TRENCHES, VEGETATED SWALES, OR FILTER BERMS MAY ALSO BE USED.

SECONDARY CONTAINMENT SHOULD BE USED TO PREVENT THE POTENTIAL LEAK OF CHEMICALS USED DURING

DEWATERING, SUCH AS CHEMICALS FOR FLOCCULATION.

CONCRETE WASHOUT

DISCHARGE OF EXCESS OR WASTE CONCRETE AND/OR WASH WATER FROM CONCRETE TRUCKS WILL BE ALLOWED ON THE CONSTRUCTION SITE, BUT ONLY IN DESIGNATED LINED AND DIKED AREAS TO PREVENT CONTACT BETWEEN THE CONCRETE AND/OR WASH WATER AND STORMWATER THAT WILL BE DISCHARGED FROM

THE SITE. THE DESIGNATED CONCRETE WASHOUT SHALL BE INDICATED WITH SIGNAGE.

ANY DISCHARGE FOR WASHING AND/OR RINSING WATERS FROM CONCRETE MIXING EQUIPMENT INCLUDING READY MIX TRUCKS IS PROHIBITED. SUCH POLLUTANTS SHALL BE ADEQUATELY TREATED AND CANNOT BE DISCHARGED TO WATERS OF THE STATE. ANY SPILLS SHALL BE CLEANED IMMEDIATELY UPON DISCOVERY.

DUST CONTROL

LARGE AREAS OF SOIL THAT ARE DENUDED OF VEGETATION AND HAVE NO PROTECTION FROM PARTICLES BEING PICKED UP AND CARRIED BY WIND SHOULD BE PROTECTED WITH A TEMPORARY COVER OR KEPT UNDER CONTROL WITH WATER OR OTHER SOIL ADHERING PRODUCTS TO LIMIT WIND TRANSPORTED PARTICLES EXITING

THE SITE PERIMETER.

WATER TRUCKS OR OTHER DUST CONTROL AGENTS ARE TO BE USED AS NEEDED DURING CONSTRUCTION TO MINIMIZE DUST GENERATED ON THE SITE. TACKIFIERS MAY BE USED TO HOLD SOIL IN PLACE AND PREVENT DUST.

MANUFACTURER RECOMMENDATIONS FOR APPLICATION RATES MUST BE USED FOR DUST CONTROL

APPLICATIONS. DUST CONTROL MUST BE PROVIDED BY THE CONTRACTOR TO A DEGREE THAT IS IN COMPLIANCE

WITH APPLICABLE LOCAL AND STATE DUST CONTROL REGULATIONS.

TREATED AND CANNOT BE DISCHARGED TO WATERS OF THE STATE.

SOLID WASTE

NO SOLID MATERIALS, INCLUDING CONSTRUCTION MATERIALS, ARE ALLOWED TO BE DISCHARGED FROM THE SITE WITH STORMWATER. ALL SOLID WASTE, INCLUDING DISPOSABLE MATERIALS INCIDENTAL TO THE MAJOR CONSTRUCTION ACTIVITIES, MUST BE COLLECTED AND PLACED IN CONTAINERS. THE CONTAINERS SHALL BE EMPTIED WHEN 95% FULL, OR AS NECESSARY, BY A CERTIFIED TRASH DISPOSAL SERVICE AND HAULED AWAY FROM THE SITE. COVERS FOR THE CONTAINERS SHALL BE PROVIDED AS NECESSARY TO MEET STATE AND LOCAL

REQUIREMENTS. CONSTRUCT COVERS AS PRACTICABLE, OR REQUIRED, TO PREVENT STORMWATER CONTACT

AND POLLUTANT DISCHARGES FROM SOLID WASTE RECEPTACLES.

SANITARY FACILIITIES

ALL PERSONNEL INVOLVED WITH CONSTRUCTION ACTIVITIES MUST COMPLY WITH STATE AND LOCAL SANITARY OR SEPTIC SYSTEM REGULATIONS. TEMPORARY SANITARY FACILITIES WILL BE PROVIDED AT THE SITE THROUGHOUT THE CONSTRUCTION PHASE. PORTABLE TOILETS MUST BE KEPT AWAY FROM DRAINAGE COURSES AND LOW AREAS AND SECURELY ANCHORED SUCH THAT THEY WILL NOT BE TIPPED OR KNOCKED OVER.

SECONDARY CONTAINMENT FOR EACH PORTABLE TOILET SHALL BE PROVIDED TO PREVENT THE DISCHARGE OF

SEWAGE ON-SITE.

STOCKPILE MANAGEMENT

MATERIALS RESULTING FROM CLEARING AND GRUBBING EXCAVATION OPERATIONS AND OTHER SUCH SOIL STOCKPILES SHALL BE CONSOLIDATED UP SLOPE FROM ADEQUATE SEDIMENTATION CONTROLS. DIVERSIONS, BERMS, DITCHES, STORAGE BASINS, ETC. WILL BE USED IN ORDER TO DIVERT, RETAIN, OR DETAIN FLOWS OR OTHERWISE LIMIT EXPOSURE TO AND DISCHARGE FROM STOCKPILES. INACTIVE STOCKPILES SHALL BE STABILIZED IN ACCORDANCE WITH THE SPECIFICATION INDICATE IN THE GENERAL PERMIT OR AS SPECIFIED
