Copyright c 2026

Isaac M. DaRowe Rainwater Harvesting System Designer

PERMEABLE PAVER - CONSTRUCTION NOTES:

1. Installer shall create a construction sequence plan

2. A pre-construction meeting shall be required to discuss:

2.1. Construction sequencing

2.2. Erosion control adjacent to the permeable pavers

2.3. Prevention of stormwater run-on until the permeable pavers are installed

3. Excavate using the smallest equipment possible and work from the sides/perimeter of the facility to avoid over-compaction of the subbase

4. Excavate a level base or slope slightly away from a building/structure

5. The condition of the soil subgrade is unknown in the location of the permeable paver parking at this time. The installer shall provide the designer with a 72 hour notice prior to excavation of the parking area. After the excavation the designer shall determine the condition of the soil subgrade in the location of the proposed permeable pavers. If soil amendments are required due to compacted or impervious soil conditions, then a proposed method will be submitted with the amendment recommendations to the client for approval

6. Scarify native soils to 3 or 4 inch depth and install geotextile fabric as noted in the detail section

7. Install base layer in 6 inch lifts. Use a vibratory roller for compaction until there is no visible movement of the aggregate. Do not crush the aggregate

8. Install aggregate base:

8.1. Base layer - No. 2 stone

8.2. Intermediate layer - No. 57 stone

8.3. Bedding layer - No. 8 stone

9. Install the permeable pavers:

9.1. The pavers are installed by hand or by machine that places a whole pallet section of pavers at one time

9.2. The pavers are compacted and then No. 8 stone spread on the pavers and swept into the openings

9.3. The pavers are compacted again so that the No. 8 stone is just below the paver structure when complete

10. No excavation of native soils to occur during wet or saturated conditions

PERMEABLE PAVER - MAINTENANCE NOTES:

General maintenance:

1. Determine maintenance schedule (annual is likely) based on final permeable paver product installed.

Refer to manufacturer's recommendations

2. Inform contractors working on the property of the locations of permeable paver area(s). A sign is recommended that identifies the surface as permeable

3. Inspect the permeable paver area after storms to ensure rainwater properly drains through the material

Typical annual maintenance:

4. Inspect the permeable paver installation after the initial storm event and seasonally to ensure there is no ponding water

5. Perform (1) surface infiltration test in accordance with ASTM 1701 Standard for every 500 S.F. of permeable paver surface

6. Clean permeable paver with high efficiency vacuum, sweeper-vacuum or walk behind vacuum to remove surface debris

7. Identify and stabilize any sediment sources adjacent to permeable paver area

8. Maintain adjacent landscaping to prevent excessive growth and debris onto permeable paver area

9. Remove excessive moss or other plant growth from permeable paver area using pressure washer, weed burner or an equivalent method. Remove any washed out sediment/debris

10. Replace/replenish the top layer of No. 8 stone between the joints with new clean No. 8 stone after sweeping, vacuuming, pressure washing or when stone is below specified height

11. Remove leaves from the permeable paver surface as needed

12. Snow removal:

12.1. Remove snow with a rubber tipped shovel/plow or keep the plow tip 1 inch above the surface by means of a skid or roller to avoid damage to permeable paver surface

12.2. Salt applications can often be reduced significantly since water drains and black ice does not form easily

12.3. Salt applications do stay on the permeable paver surface longer since it does not wash off compared to regular impervious surfaces that shed water

12.4. Do not apply sand on the permeable paver surface

Non-Routine maintenance:

13. Do not stockpile mulch, sand, soil, yard waste, snow containing sand or salt or any other material on the permeable paver area that could potentially clog the pore space between the joints

14. Protect permeable paver surface from sediment during installation of adjacent planting areas or infrastructure

15. Replace broken permeable paver as needed following manufacturers guidelines

16. Remove and replace permeable paver for utility repairs

17. Clean (rehab) clogged permeable paver using high pressure wash and vacuum to remove desired depth of aggregate. Replace aggregate to specified height

18. Do not replace vehicle fluids or wash a car/equipment over the permeable paver surface

19. Do not apply sealants or any other materials that prevent water to pass through the permeable paver surface

8. More frequent water and weeding may be required during the first two years until the plants are established

9. Replace plants as needed to maintain 80% plant coverage

10. Replace mulch so built-up pollutants do not harm the vegetation and maintain a 3 inch depth

11. Check for erosion and sediment accumulations in ponding area

12. Remove any sediment or vegetation accumulation at inlet/overflow

13. Water during drought periods

14. Clean matted vegetation on rain garden bottom

RAIN GARDEN - CONSTRUCTION NOTES:

1. Installer shall create a construction sequence plan

2. A pre-construction meeting shall be required to discuss:

2.1. Construction sequencing

2.2. Erosion control adjacent to the rain garden

2.3. Prevention of stormwater run-on until the rain garden

is installed and stabilized

3. Installer shall prevent over-compaction of the rain garden area and adjacent areas

4. No excavation, soil placement or soil amendment shall occur during wet or saturated conditions

5. Operate any and all construction equipment adjacent to the proposed rain garden not in the rain garden area

POROUS ASPHALT - CONSTRUCTION NOTES:

1. Contractor shall create a construction sequence plan

2. A pre-construction meeting shall be required to discuss:

2.1. Construction sequencing

2.2. Erosion control adjacent to the porous asphalt

2.3. Prevention of stormwater run-on until the porous asphalt is installed

3. No excavation of native soils to occur during wet or saturated conditions

4. Excavate using the smallest equipment possible and work from the sides/perimeter of the facility to avoid over-compaction of the subbase

5. Excavate a level base or slope slightly away from a building/structure

6. Scarify native soils to 3 or 4 inch depth and install geotextile fabric as noted in the detail section

7. Install base layer in 6 inch lifts. Use a vibratory roller for compaction until there is no visible movement of the aggregate. Do not crush the aggregate

8. Install aggregate base: 12" of 1 1/2" double washed crushed stone and compacted

9. Install choker course: 2"of 3/4" double washed crushed stone and compacted

10. Install the porous asphalt:

10.1. The porous asphalt shall be installed like conventional asphalt. The porous asphalt is placed in an asphalt machine from a dump truck at a specific temperature according to manufacturer

10.2. The porous asphalt is compacted using a 10-ton static roller

11. After installation of the porous asphalt, a minimun of (2) infiltration tests shall be conducted in accordance with ASTM 1701 standard. the results of the infiltration tests shall be provided to the designer and system owner.

POROUS ASPHALT- MAINTENANCE NOTES:

General maintenance:

1. Determine maintenance schedule (bi-annual is likely) based on final porous asphalt product installed. Refer to manufacturer's recommendations

2. Inform contractors working on the property of the locations of porous asphalt area(s). A sign is recommended that identifies the surface as permeable

3. Inspect the porous asphalt area after storms to ensure rainwater properly drains through the material

Typical annual maintenance:

4. Inspect the porous asphalt installation after the initial storm event and seasonally to ensure there is no ponding water

5. Perform (1) surface infiltration test in accordance with ASTM 1701 Standard for every 500 S.F. of porous asphalt surface

6. Clean porous asphalt with high efficiency vacuum, sweeper-vacuum or walk behind vacuum to remove surface debris

7. Identify and stabilize any sediment sources adjacent to porous asphalt area

8. Maintain adjacent landscaping to prevent excessive growth and debris onto porous asphalt area

9. Remove excessive moss or other plant growth from porous asphalt area using pressure washer, weed burner or an equivalent method. Remove any washed out sediment/debris

10. Replace/replenish the top layer of No. 8 stone between the joints with new clean No. 8 stone after sweeping, vacuuming, pressure washing or when stone is below specified height

11. Remove leaves from the porous asphalt surface as needed

12. Snow removal:

12.1. Remove snow with a rubber tipped shovel/plow or keep the plow tip 1 inch above the surface by means of a skid or roller to avoid damage to porous asphault surface

12.2. Salt is acceptable for use as a deicer on the porous asphault though non-toxic, organic deicers, applied either as a blended, magnesium chloride-based liquid products or a preteated salt, are preferable. Any deicing materials should be used in moderation

12.3. Snow storage on the porous asphault should be avoided, because it could lead to clogging due to sediment accumulation

12.4. Do not apply sand on the porous asphault surface

Non-Routine maintenance:

13. Do not stockpile mulch, sand, soil, yard waste, snow containing sand or salt or any other material on the porous asphalt area that could potentially clog the pore space between the joints

14. Protect porous asphalt surface from sediment during installation of adjacent planting areas or infrastructure

15. Replace porous asphalt for utility repairs or other purposes with like material if available. If not, patch with conventional asphalt. Patched with convetional asphalt shall not exceed 10% of the total porous asphalt area

16. Remove and replace porous asphalt for utility repairs

17. Clean (rehab) clogged porous asphalt using high pressure wash and vacuum

18. Do not replace vehicle fluids or wash a car/equipment over the porous asphalt surface

19. Do not apply sealants or any other materials that prevent water to pass through the porous asphalt surface
