We have reviewed this submittal and otTer the following comments: APPLICATION SUMMARY The Applicant, Wenco Inc., has submitted proposed amendments to the existing Landscape Ordinance (MCC 12-13-7-8 and 12-13-7-13.B). The proposed amendments' primary focus is on allowing rock and gravel as an approved mulch in commercial landscape areas. ORDINANCE HISTORY Current ordinance prohibits the use of rock and gravel as mulch in required landscape areas. Instead, it requires the use of bark, soil aid or other organic mulch. During preparation of the ordinance, we received input ftom the extension agency and others that organic mulches are preferable for several reasons. For example, bark and other organic mulches help retBin moisture available to plants, while rock cannot soak up or retain any water. A 2"-3" layer of bark can significantly control weeds on its own, while rock will not usually control weeds without the addition of a weed barrier under the rock. Bark helps moderate soil temperatures, while rock can absorb and reflect heat which exacerbates soil temperatures, creating stress on plants. Thus, current ordinance reads as follows: 12-13-7-8 Mulch: An organic mulch such as bark or soil aid shall be applied to all planting areas for moisture retention, weed contro~ and moderation of soil temperatures.... Gravel/rock mulch is prohibited in required landscape areas per [12-13-7-13.B]. 12-13-7-13.B (Water Efficiency section) Mulch: Mulches shall be organic and broad uses of gravellrock mulch are restricted as per Section [12-13-7-8]. Gravel does not retain water, reflects heat, and causes greater stress on trees and shrubs. Organic mulch retains water for a longer period of time for plants. Landscape Ordinance,ZOA Planning & Zoning Commision, Mayor and Council October 15,2004 Page 2 Another reason that rock/gravel were restricted was due to the then-recent installation of a couple of street buffers that used gravel exclusively as the groundcover with no shrubs or grass and were deemed undesirable for the look of a street buffer. Thus, the ordinance includes a restriction against "broad uses of graveVrock mulches" (see above) and a later requirement in 12-13-10-6 and 12-13-1I-3,E for street buffers and parking lot islands to be planted with "shrubs, lawn, or other vegetative groundcover." The point was for these required landscape areas to be vegetated and not just covered in gravel. Since that time, interest has grown for the use of rock as a mulch for three primary reasons. First, rock mulch is permanent, while bark, soil aid and other organic mulches have to be replaced every couple of years to stay looking nice. Second, organic mulches blow and wash out of planter beds during wind and rain storms more easily than rock does. Third, with the closure of many lumber mills in the Northwest, quality bark products are becoming increasingly difficult for nurseries to stock. In addition, regarding plant stress, applicants are able to point to existing areas that use rock mulch where the plants appear perfectly healthy. Staff agrees that there may be room for compromise on this issue, as detailed in the comments, below. These comments are a compilation ftom P&Z, Parks, and other staff. COMMENTS 1. ~: Rock mulch used in planting areas around shrubs or under other vegetative groundcovers is acceptable to staff. However, the use of rock and gravel as the only groundcover without vegetation should still be prohibited. The goal of providing vegetated landscape buffers is still valid, The street buffers, parking lot islands and other required landscape areas should be designed so that at least 70% of the ground is covered (at maturity) with vegetation. Rock mulches can be used around the shrubs or other plants. 2. Types of Rock: The landscape industry is now producing many varieties of rock, often called "permabark," that can be attractive as a mulch. Things have come a long way from the days of red lava rock and white quartz as the only choices. However, certain types of rock should still be restricted. For example, pea gravel, washed 2" drain rock, road base gravel, and similar products should not be used as mulch. 3. Edging: Staff is aware of certain areas in town where rock mulch has been used and it is constantly migrating onto adjacent sidewalks, especially if the area is bermed. Rock mulch should be contained by a curb or some form of edging that prevents it from rolling onto adjacent surfaces. 4, Weed Barrier: Ifrock mulch is used, a weed barrier should be required beneath the rock. The weed barrier should be one of the many available permeable weed fabrics so that air and water are sti11 able to get to the roots of surrounding trees and shrubs, Impermeable plastic weed barrier is already prohibited perMCC 12-13-7-8. 5. Water Conservation: Allowing rock may have the effect of promoting street buffers with shrubs and rock mulch instead of the current prevalence of lawn. This could aid the City's Landscape Ordinance,ZOA Planning & Zoning Commision, Mayor and Council October 15,2004 Page 3 water conservation efforts, as shrubs and other vegetative groundcovers require much less water and maintenance than lawn areas. RECOl\fMENDA TION Staff recommends approval of the proposed Zoning Ordinance Amendment as amended below. 12-13-7-8 Mulch: Mulch shall be used in all required planting areas. Approved mulches may be organic, such as bark or soil aid, or they may include rock products, such as "permabark" or similar products. Use of mulch, organic or rock, as the only groundcover in required planting areas is prohibited, Required landscape areas shall be at least 70% covered with vegetation at maturity, with mulch used under and around the plants. Pea gravel, drain rock, road base gravel, and similar products shall not be used as mulch. All mulch shall be contained by a curb or other edging material to contain the mulch and prevent it ftom migrating to adjacent surfaces. If rock mulch is used, a weed barrier fabric shall be used beneath the rock Impermeable plastic weed barriers are prohibited because they restrict water and oxygen to the plants. 12-13-7-13.B Mulch: Mulches may be organic or rock as per Section 12-13-7-8. Low shrubs or other vegetative groundcovers with mulch are preferred over lawn areas wherever feasible due to the lower water requirement of shrubs.
