The renovation of balboa park, the oldest in the city of san francisco, and now it is the newest part in the city of san francisco. Through our partnership, and because of Public Investment from the two thousand eight fund, we are celebrating a renewal and an awakening of this park. We have it safer, happier, more joyous. 3, 2, 1, [laughter] [applause] it is a great resource for families, to have fun in the city, recreation. This is an amazing park. We have not revitalized it without public and private investment. The critical piece of the process of this renovation was that it was all about the community. We reached out to everyone in this community. We love this park dearly and they all had thoughts and ideas and they wanted to bring their own creativity and their personality to bear on the design. What you see is what the community wanted. These ideas all came from the residents of this community. As a result, there is a sense of ownership, pride and responsibility that goes along with what is going to be an exciting park. Hello, everybody. This is the department of brown bag lunch. We are Walking Around looking at trees on the hottest day of the year in san francisco. Theres a few bicycles coming and going. It must be a long hot day to be bike riding. Were joined with carla short whos the city urban forrestor. Is that right . Uhhuh. Shes going to look at trees and talk about tree issues. And we invite your questions. She knows all about trees. We have a whole pile of trees ready to put b put in the ground. What kind of trees are they. Victorian box trees. What size are they . A 24 inch box, which is the new standard. We do at least 24inch box or larger unless the site is to constrained that we have to go small every. Er smaller. It increases the survival rate of the tree. So this is our new standard. It takes a little while until they can adapt to the location. How long does that usually take . A couple of seasons . It does. We normally will water a tree throughout the dry season which we estimate about nine months of the year. So if it is has not rained, we have to go water the tree. Once it is established, then it does not need our help. Theres a particular problem with trees that are in boxes or in planters or that are not planted in the ground and thats that they have a lot of area of evaporation. So trees like this that are sitting in boxes in sidewalks need a lot of care and a lot of water. Thats right. We would water these extra so several times a week while we are waiting. One of the reasons why we try to get trees planted in the ground rather that in raised plantearns is because you only have to water for a few seasons. If you put it in a planter box youre going to be watering it for the rest of your life you often see dead plants and that is because they dry out so fast. It says ud undulaem mean . Undough undolatting. What can they tell us . Form. Form is s. So thats a good thing we can note. Thats what we call standard form. Which when you are talking about a tree, it looks like a tree. It has one trunk. The other forms are multistems or multitrunk. So for street trees it is important to have that standard form because we need to have clearances for pedestrian and vehicular access. Quantity 50. Well, hmm, guess there are 50 of them. What does this mean . L. M. It means lance scape maintenance landscape maintenance. We know which project they are for. And this nursery would have said something about the fertilization history. Thats right. And they do to have that on there. We try to get trees established into their natural environment. Once we get phlegm the nursery, we get the nursery, we will try to already have them established. We dont do a lot of fertilizing. If there is really bad soil conditions then we might amend the soil. Do people need to fertilize their trees. Typically they dont if you are planting in your own yard, and if they have some products that are root stim lay tors, there are fungi that will help your roots adapt. You can scatter it around the roots and water it in. And it helps those roots to develop and get adapted. But generally most trees dont need a lot of fertilization if your soil conditions are very bad, you might want to amend the soil, i always like to do organic soil. We work with a variety of nurseries in the area. So theres not just one. We have some nurseries where we get a lot of the same species that ke with count on them. Sometimes we have to go a little bit further up field. There are a few nurseries that they are not based in the city. They are based in the nearby areas where there is more land. And they have to be acityapproved vendor. So we are restricted a lot of times is having that paperwork. Everybody is qualified, they just havent done that. But there are some good
