Checklist #19 https://sclhresidents.com/documents/10184/251862/Checklist+19+Landscape+Plants+Trees/1972f43b-39e2-44b2-940b-6ef4698d2cb8?version=1.2 (The ARC 'Plant and Tree List' detail worksheets currently begin on page 6 of Checklist #19) DG Appendix A, Acceptable Plant List https://sclhresidents.com/documents/10184/252552/Acceptable+Plant+List/0cde3f9c-8a2a-45e7-b052-3c0432a1ca7f?version=1.1 Design Guidelines Effective 4/10/17 https://sclhresidents.com/documents/10184/13538/Design+Guidelines+%28Effective+2017.04-10%29/a7d7c78c-2e95-4ce5-9154-123c46e3d929?version=1.1 EXCERPTS: The red font below is added emphasis by myself. Checklist #19 -- Landscape Plants and Trees Required Documents: -- A detailed landscape plan drawn at a minimum scale of 1/8" = 1.0', showing the location of new and existing plants, trees, drains, grading and required setbacks for plants and trees**. -- A plant and tree list with plant names and a legend (color code, letters, or numbers). -- Calculations showing how the required plant quantities are being met (see the attached Calculation Worksheet and Calculation Summary Sheet). ** The ARC - DG underscored emphasis for minimal scale of 1/8" = 1.0', effectively ruled out copying my original, 1" = 10.0' scaled purchase plan landscape diagram -- adjusted in the past by us non-professional gardeners, whenever adding / replacing plants and trees for ARC approval, or, switching a small area from turf to bark as undertaken by the above, frustrated resident ..... The need to use a new diagram scale potentially invoking a paid professional agent to convert my original lot plan, did not leap to my own eye: -- On my purchase plan diagram with scale 1" = 10.0', the standard, 5-foot setback from property lines for most trees is represented by 4/8 inch. -- On the new mandatory minimum scale 1/8" = 1.0' diagram, a 5-foot setback is represented by 5/8 inch. ....................................................................................................... The ARC-DG solution for perceived plant excess "Fewer than the minimum plant quantities may be considered for approval if the design drawing clearly shows that the number of plants provided will achieve the stated goal of fifty percent coverage at MATURITY ...." Checklist #19 and DG 6.1 ....................................................................................................... DG 6.1 Design Requirements and Minimum Plant Quantities "All landscape designs shall be prepared by a Landscape Architect, Landscape Designer, or Licensed Landscape Contractor. If an Owner is capable of preparing a design and drawing that meets the stated requirements, they may prepare and submit their own drawing." ........................................................................................ "Each fifty (50) or (100) square feet of plantable area shall contain the following minimum plant quantities with the goal of achieving fifty percent (50%) plant coverage at maturity ...." See 6.1 Table: 4 shrubs / 50 SF = 2 (5 gal) + 2 (1 or 2-gal) 8 shrubs /100 SF = 4 (5 gal) + 4 (1 or 2-gal) ....................................................................................................... DG 6.2 Front Yard and Corner Lot Street Side Yard Landscaping Requirements "For front yards and corner lot street side yards, a minimum of fifty percent (50 %) of the plantable area, must be covered with an approved living material such as shrubs and ground cover plants. The required coverage must be achieved when the plants reach MATURITY." "Each individual nonturf area of the yard shall have the required coverage. This includes both sides of the driveway. The remaining plantable area shall be covered with approved bark or a combination of approved bark and decorative rock." ....................................................................................................... |

How to calculate expected plant growth SF coverage ....
Add two columns to the ARC Plant & Tree List detail worksheets from Checklist #19 (page 6), for calculating the SF ground coverage expected at maturity for each type of plant: Mature Size Expected Coverage (H' x W') (No. x PCSF) Mature Size: Use data from DG Appendix A, Accepted Plants & Tree List, local nurseries, or Internet sites for plant expected height 'H' and width 'W' at maturity. DG Appendix A, Acceptable Plant List https://sclhresidents.com/documents/10184/252552/Acceptable+Plant+List/0cde3f9c-8a2a-45e7-b052-3c0432a1ca7f?version=1.1 Expected Coverage: The quantity of each plant type (No.) times the PCSF (plant coverage SF) expected for that plant type's width (W') listed in "Plant Coverage SF Table" Plant Coverage SF Table W = width in feet = 1' 2' 3' 4' 5' 6' 7' 8' 9' 10' PCSF = 3.14 x (W / 2)^2 = 1 3 7 12 20 28 38 50 64 78 SF Area (SF area of circle) Example: I have 3 dwarf Lemon Bottlebrush, each expected to grow 3 feet tall and 5 feet wide. The above table shows the plant coverage area SF (PCSF) for every 5' wide plant = 20 SF. Expected coverage for these 3 plants = 3 plants x 20 PCSF at 5' = 60 SF total area.. |

DG - Appendix A ACCEPTABLE PLANTS -- STATS Approximately 180 shrubs and ground cover plants on this list are 1 to 5 feet tall at maturity. 140 (78%) of these are three feet wide or greater = minimum 7 SF and maximum 78 SF plant area coverage per EACH 100 SF of PA 40 (22%) of these are from one to two feet wide IF .... every 8-plant combination for any PA uses plants 3' wide or more ..... then, plant coverage will range from a MINIMUM of 56 SF and MAXIMUM of 624 SF for EACH 100 SF .... IF .... every 8-plant combination for any PA uses plants UNDER 3' wide ..... then, plant coverage will range from a MINIMUM of 8 SF and MAXIMUM of 24 SF for EACH 100 SF ...... ...... The effort to juggle DG-required combinations of 8 plants per each 100 SF, to try to attain 'no more and no less' than 50% coverage for avoiding unnecessary irrigation can conceivably be more time-consuming and less efficient, than simply comparing all expected plant growth area SF data to a 50% PA goal ... ? |
